This disclosure relates generally to textiles and, more particularly, to a method, an article of manufacture, device and/or a system of production of high cotton number or low denier core spun yarn for weaving of reactive fabric and enhanced bedding.
The comfort of a woven textile against the human skin may be related and/or directly proportional to a thread count. Use of the coarse diameter yarn may lead to a low “thread count” in the woven textile. In contrast, using relatively fine yarns yield a high thread count. A thread count of a textile may be calculated by counting the total weft yarns and warp yarns along two adjacent edges of a square of the woven textile that is one-inch by one-inch. A high thread count may be a commonly recognized indication of the quality of a woven textile, and may also be a measure that consumers associate with tactile satisfaction and opulence.
A core spun yarn that is comprised of a core filament and a sheath may be used in a production of a woven textile to create a new yarn and/or a fabric that has some characteristics of a material of the core filament and some characteristics of a material of the sheath. For example, a core spun yarn comprising a spandex core and a cotton sheath may have an ability to stretch like a spandex polymer, but still retain a set of favorable characteristics of cotton such as a pleasant feeling to human skin and/or an ability resist a sticky sensation. Core spun yarn may also be referred to a “polycore” yarn, and may be created by twisting a set of staple fibers (also known as a roving) and/or a synthetic yarn (e.g., a polyester yarn) around a central filament core that may be made of a synthetic polymer (e.g., polyester, spandex).
Core spun yarns may be used in the production of some woven apparel items, but may not have yet been adapted to the production of bedding fabrics or certain types of fine apparel. When the core filament is reduced in diameter in order to construct a corresponding core spun yarn of reduced diameter, the core filament may break during the process by which the sheath is added to the core filament. A smaller diameter instance of the core filament may also break when fed into a loom apparatus to weave the woven textile. Therefore, use of core spun yarn may be limited to applications that tolerate a low thread count, which may prevent imparting the beneficial characteristics of core spun yarns to a set of woven textiles that require a relatively high thread count to be considered usable, saleable, and/or desirable.
Disclosed are a method, an article of manufacture, device and/or a system of production of high cotton number or low denier core spun yarn for weaving of reactive fabric and enhanced bedding.
In one aspect, a woven textile fabric includes a warp yarn and a weft yarn. The weft yarn is a core spun yarn having a spandex core, and the woven textile fabric is a sateen weave and/or a plain weave.
The methods and devices disclosed herein may be implemented in any means for achieving the various aspects. Other features will be apparent from the accompanying drawings and from the detailed description that follows.
Example embodiments are illustrated by way of example and not limitation in the Figures of the accompanying drawings, in which like references indicate similar elements and in which:
Other features of the present embodiments will be apparent from the accompanying drawings and from the detailed description that follows.
Example embodiments, as described below, may be used to provide a method, an article of manufacture, device and/or a system of production of high cotton number or low denier core spun yarn for weaving of reactive fabric and enhanced bedding
In one embodiment, a method of producing a core spun yarn includes drawing a partially oriented yarn from a polyester supply package through a primary input roller to form an oriented polyester yarn, and drawing the oriented polyester yarn through a secondary input roller. The method further includes drawing the oriented polyester yarn through a primary heater, exposing the oriented polyester yarn to a cooling plate, and drawing the oriented polyester yarn through a friction twisting unit using an intermediate roller. The method also includes drawing a spandex core from a spandex bobbin to become associated with the oriented polyester yarn at a supporting guide located between the friction twisting unit and the intermediate roller.
The method includes drawing both the spandex core and the oriented polyester yarn through an intermingling jet, and texturizing the oriented polyester yarn using the intermingling jet using a hot air punching technique. Also included is twisting the oriented polyester yarn around the spandex core using the intermingling jet and the friction twisting unit, as well as drawing the oriented polyester yarn and the spandex core through a NFR roller after the intermingling jet. Finally, the method includes heating the oriented polyester yarn and the spandex core using a secondary heater to form the core spun yarn.
The primary heater and the secondary heater may be set to a temperature between 50° C. and 200° C. Also, the cooling plate may be set to a temperature between 0° C. and 40° C. The intermingling jet may apply a uniform air pressure to the oriented polyester yarn to provide a counter-twist opposing the friction twisting unit. Additionally, the friction twisting unit may manipulate the oriented polyester yarn such that the oriented polyester yarn gains a texture and/or a weaving stability. Also, the manipulation may include a twisting and/or a detwisting.
The method may include fixing a torsion of the oriented polyester yarn by translating a twist imparted by the friction twisting unit through the oriented polyester yarn back to the primary heater. The secondary input roller may be a twist-stopper preventing the twist from propagating to the polyester supply package. The spandex core may have a denier of 20 to 300.
In another embodiment, a method of producing a core spun yarn includes drawing a roving thread from a roving bobbin through a roving guide, an aft drafting roller, and a mid drafting roller to a front drafting roller. The method further includes drawing a spandex core from a spandex bobbin using a guide roller, associating the roving thread and the spandex core by drawing the roving thread and the spandex core in an approximately parallel fashion through the front drafting roller, and drawing the roving thread and the spandex core through a lappet hook and an anti-ballooning guide. Finally, the method includes winding the roving thread and the spandex core on a ring-frame bobbin including a ring traveler attached to a rotatable ring. A circular motion of the ring traveler around the ring-frame bobbin causes the roving thread to twist around the spandex core, forming the core spun yarn. The roving thread may include cotton staple fibers and/or polyester staple fibers.
In yet another embodiment, a woven textile fabric includes a warp yarn and a weft yarn. The weft yarn is a core spun yarn having a spandex core, and the woven textile fabric is a sateen weave or a plain weave. The woven textile fabric may assume a native state in the absence of external strain, and may assume a first distributed state when experiencing a first strain. Furthermore, the woven textile fabric may assume a second distributed state when experiencing a second strain. The first distributed state may include a slight stretch of the weft yarn which inhibits wrinkles while inhibiting airflow through the woven textile fabric. The second distributed state may include a further stretching of the weft yarn which may permit an enhanced airflow through the woven textile fabric.
The warp yarn may be 100% cotton and have a 60 Ne count, while the core spun yarn may be a roving-spandex yarn and have a 60 Ne count including the spandex core. The spandex core may have a denier from 20 to 300, and the roving-spandex yarn may include a cotton staple sheath and the spandex core. Additionally, the woven textile fabric may also include from 170 to 200 ends per inch of warp yarns, from 100 to 110 picks per inch of the core spun yarn, and a total thread count from 270 to 310. A material content of the woven textile fabric may be approximately 97% to 98% cotton and approximately 2% to 3% spandex, by weight.
Alternatively, the warp yarn may be 60% cotton and 40% polyester and have a 45 Ne count. The core spun yarn may be a roving-spandex yarn and have a 60 Ne count including the spandex core. The spandex core may have a denier of 20 to 300, and the roving-spandex yarn may include a cotton staple sheath and the spandex core. The woven textile fabric may also include from 148 to 170 ends per inch of warp yarns, from 88 to 100 picks per inch of the core spun yarn, and
a total thread count from 240 to 270. A material content of the woven textile fabric may be approximately 72% cotton, approximately 25% polyester, and approximately 3% spandex, by weight.
The warp yarn may be 100% cotton and have a 60 Ne count, and the core spun yarn may be a poly-spandex yarn and have a 60 Ne count including the spandex core. The spandex core may have a denier of 20 to 300. The poly-spandex yarn may include the spandex core and a sheath including a set of intermingled polyester filaments derived from a polyester strand, and the poly-spandex yarn may have a denier of at least 95. The woven textile fabric may also include from 170 to 200 ends per inch of warp yarns, from 70 to 80 picks per inch of the core spun yarn, a total thread count from 250 to 270. A material content of the woven textile fabric may be approximately 94% to 95% polyester and approximately 5% to 6% spandex, by weight.
The warp yarn may be 60% cotton and 40% polyester and have a 45 Ne count, while the core spun yarn may be a poly-spandex yarn and have a 90 Ne count including the spandex core. The spandex core may have a denier of 20 to 300. Also, the poly-spandex yarn may include the spandex core and a sheath including a set of intermingled polyester filaments derived from an oriented polyester yarn. The woven textile fabric may also include from 148 to 170 ends per inch of warp yarns, from 88 to 100 picks per inch of the core spun yarn, and a total thread count from 250 to 270. A material content of the woven textile fabric may be approximately 37% cotton, approximately 61% polyester, and approximately 2% spandex, by weight.
The poly-spandex yarn 100 may be a yarn made out of a combination of polyester and spandex. Polyester is a synthetic resin in which the polymer units are linked by ester groups. Spandex is a type of stretchy polyurethane fabric. The set of intermingled polyester filaments 102 may be a combination of thin polyester strands. The spandex core 104 may be the strand of spandex material which serves as the core of a core spun yarn. The spandex core will be wrapped in a sheath made of a yarn or other material.
The sheath 105 may be a close fitting cover for something, such as a core. By wrapping a core (e.g. a spandex core, etc.) in a sheath made out of a different material (e.g. cotton, polyester, etc.), one may obtain the benefits of both materials. The polyester supply package 106 may be a spool, a reel, or other form of packaging for a polyester thread or yarn. The partially oriented yarn 108 may be polyester yarn as it is just coming off of a container, such as a polyester supply package. The primary input roller 110 may be a roller through which a yarn may pass. The oriented polyester yarn 112 may be a polyester yarn after passing through a primary input roller. The secondary input roller 114 may be a roller through which a yarn may pass. In some embodiments, the secondary input roller 114 may also serve as a twist-stopper that prevents a twist from propagating to the polyester supply package.
The primary heater 116 may be a device for supplying heat to a yarn or thread being drawn through it. The cooling plate 118 may be a device used to chill or cool a thread or yarn which is passing through it. The friction twisting unit 120 may twist/detwist a set of the filaments comprising the oriented polyester yarn 112 such that the oriented polyester yarn 1121 gains a texture (e.g., such that within the resulting textile that the poly-spandex yarn 100 may be woven into gains in “body” and/or heft) and may also provide a low stability interlacing in a weaving process. The friction twisting unit 120 may also help to intermingle the filaments comprising the oriented polyester yarn 112 such that they provide a more uniform and comprehensive instance of the sheath 105.
The spandex bobbin 122 may be a cylinder or cone holding a spandex thread or yarn. The supporting guide 124 may be a guide which facilitates the introduction of the oriented polyester yarn to the polyester core, which may be coming from different directions. The intermediate roller 126 may be a roller which may be used to pull one or more yarns, filaments, and/or threads through a system. The intermingling jet 128 may be an air jet used to texturize, combine, or otherwise manipulate yarns and threads. The NFR roller 130 may be a bearing supported roller type freewheel. In some embodiments, the NFR roller may have no sealing.
The secondary heater 132 may be an additional heater. The output roller 134 may be a roller which may be used to pull a yarn through a process or system. The oil applicator 136 may be a device for the application of conning oil near the end of a yarn fabrication process. The traverse box 138 may be a device which assists in the storage of yarn, such as the core spun yarn being fabricated in
The poly-spandex yarn 100 comprises a spandex core 104 of a denier of 20 to 300 along with the sheath 105 comprising the intermingled polyester filaments 102. The intermingled polyester filaments 102 are derived from the oriented polyester yarn 112 that is twisted around the spandex core 104. A process of producing the poly-spandex yarn 100 begins by drawing the partially oriented yarn 108 from the polyester supply package 106 to the primary input roller 110. The partially oriented yarn 108 may then be referred to as the oriented polyester yarn 112 which may then enter the secondary input roller 114. The secondary input roller 114 may be a twist-stopper that prevents a twist from propagating to the polyester supply package 106. The oriented polyester yarn 112 may then be drawn through the primary heater 116. The primary heater 116 may be heated to a temperature between 50° C. and 200° C. In one preferred embodiment, the primary heater may be set to 190° C. After leaving the primary heater 116, the oriented polyester yarn 112 may then be exposed to the cooling plate 118 that may be set at a temperature between 0° C. and room temperature (e.g., about 20-25° C.). The cooling plate may also be set at temperatures between 25° C. and 40° C., and in one preferred embodiment 38° C.
The intermediate roller 126 may draw the oriented polyester yarn 112 from the cooling plate 118 to the friction twisting unit 120. The friction twisting unit 120 (e.g., an FTU) may twist/detwist a set of the filaments comprising the oriented polyester yarn 112 such that the oriented polyester yarn 1121 gains a texture (e.g., such that within the resulting textile that the poly-spandex yarn 100 may be woven into gains in “body” and/or heft) and may also provide a low stability interlacing in a weaving process. The friction twisting unit 120 may also help to intermingle the filaments comprising the oriented polyester yarn 112 such that they provide a more uniform and comprehensive instance of the sheath 105. The twist imparted by the friction twisting unit 120 may be translated through the oriented polyester yarn 112 back to the primary heater 116, which, in conjunction with the cooling plate 118, may “fix” the molecular structure of the twisted filaments of the oriented polyester yarn 112, imbuing it with a “memory” of torsion.
The spandex core 104 may be drawn from the spandex bobbin 122 to become associated with the oriented polyester yarn 112 at the supporting guide 124, which may be located between the friction twisting unit 120 and the intermediate roller 126. The intermediate roller 126 may draw both the oriented polyester yarn 112 and the spandex core 104 through the intermingling jet 128. A combination of an action of the intermingling jet 128, which may texturize the oriented polyester yarn 112 through a hot air punching technique, along with the friction twisting unit, may twist the oriented polyester yarn 112 around the spandex core 104. The intermingling jet 128 may apply a uniform air pressure to the oriented polyester yarn 112 in order to provide counter-twist to the friction twisting unit 120. The oriented polyester yarn 112 may then be heated by the secondary heater 132. The secondary heater 132 may be set to between 50° C. and 200° C. In one preferred embodiment, the intermingling jet 115 may be set to a pressure of 2 bars and the secondary heater 132 may be set to a temperature of 170° C. Upon leaving the intermingling jets 128, the oriented polyester yarn 112 and the spandex core 104 may enter the NFR Roller 130, which may be a bearing supported freewheel-type roller without any sealing.
The combination of the spandex core 104 with the oriented polyester yarn 112, upon exiting the secondary heater 132, may be referred to as the poly-spandex yarn 100. The poly-spandex yarn 100 may have a conning oil applied by the oil applicator 136. The conning oil applied by the oil applicator 136 may act as a lubricant, reducing a friction between two or more yarns (e.g., several of the poly-spandex yarns 100) and between one or more yarns and a loom apparatus (e.g., metallic components the poly-spandex yarns 100 may contact). The conning oil may also minimize a static charge formation of synthetic yarns.
After passing the oil applicator 136, the poly-spandex yarn 100 may be drawn through a traverse box 138 by a take-up roller 140 to be wound on the poly-spandex bobbin 145. The poly-spandex bobbin 145 may be fed into a loom apparatus as a weft yarn of a woven textile (e.g., as disclosed above, the third woven textile and/or the fourth woven textile).
The roving-spandex yarn 200 may be a yarn made out of a combination of a roving fiber and a spandex material. The roving thread 202 may be long and narrow bundle of fibers. For example, the roving 202 may be produced during the process of making yarn from raw cotton, polyester fibers, and/or a combination of cotton and polyester fibers. The roving bobbin 206 may be a cylinder or cone which holds a roving. The roving guide 208 may be a device which helps ensure the roving is fed correctly into the aft drafting roller. The aft drafting roller 210 may be the first drafting roller the roving is passed through.
The mid drafting roller 212 and the front drafting roller 214 may be rollers which draw the roving thread into the system, maintaining a proper level of tension to make various properties of the thread uniform. The guide roller 216 may be a roller which assists with the introduction of the spandex core to the roving thread. The lappet hook 218 and the anti-ballooning guide 220 may be devices which assist with maintaining the ballooning of the thread within a certain limit. The ring traveler 222 may be a hook which assists with the winding of the yarn on the bobbin. The roving-spandex bobbin 245 may be a cylinder or cone which may be used to hold a roving-spandex yarn.
The roving-spandex yarn 200 comprises a spandex core 104 of a denier between of 20 to 300 along with the sheath 105 comprising the roving thread 202. Creating a core spun yarn with a 60-80 Ne count may be difficult, and may require long staple yarn fibers, a compact spinning with a high twist. To form the roving-spandex yarn 200, the roving thread 202 is drawn from the roving bobbin 206, through the roving guide 208, the aft drafting roller 210 and the mid drafting roller 212 until it reaches the front drafting roller 214. The roving thread 202 may be a thread made of cotton staple fibers and/or polyester staple fibers. Proximate to a drafting zone associated with the front drafting roller 214, the spandex core 104 is drawn from the spandex bobbin 122 by the guide roller 216. The spandex core 104 and the roving thread 202 may become associated near the drafting zone, and drawn in an approximately parallel fashion through the front drafting roller 214.
The spandex core 104 and the roving thread 202 may then be drawn through the lappet hook 218 and an anti-ballooning guide 220 to be wound on a ring-frame bobbin 224. The ring-frame bobbin 224 uses a ring traveler 222. The ring traveler 222 may be attached to a ring that may rotate. A rapid circular motion of the ring traveler 222 around the ring-frame bobbin 224 may cause the roving thread 202 to twist around the spandex core 104, which may form the sheath 105 of the roving-spandex yarn 200. The ring traveler 222 may then wrap the roving-spandex yarn 200 on the ring-frame bobbin 224 at the same time a spindle of the ring-frame bobbin 245 rotates, forming the roving-spandex bobbin 245.
The elastane weft bedding 300 may be a bed sheet made from the first woven textile, the second woven textile, the third woven textile, or the fourth woven textile, and which may be a different woven textile also made from the poly-spandex yarn 100 and/or the roving-spandex yarn 200. The user 301 may be a customer, a consumer, a guest at a hotel, or any other individual who may make use of the elastane weft bedding. The core spun weft 302 may be a core spun yarn, such as the polyester-spandex core spun yarn or the roving-spandex core spun yarn, which is being employed as a weft yarn in a textile. The first distributed state 303A and the second distributed state 303B may be states of a textile fabric which may be defined by the degree to which a stretchable weft is being stretched, due to a force being applied (e.g. the strain of being fitted on a mattress, the strain due to a user resting on top of the fabric, etc.) The warp 304 may be the yarn which is interlaced with the weft in a textile fabric. The inhibited airflow 306 may be an air flow that is prevented from passing through the elastane weft bedding. The enhanced airflow 308 may be additional or increased air which flows through the elastane weft bedding.
The present disclosure related to a number of embodiments of the woven textile that have a relatively small diameter of core spun yarn, resulting in a higher thread count and the realization of a reactive fabric that may be used as a bedding (e.g., a bed sheet, a pillow case, a duvet cover) with enhanced comfort and functionality. In one embodiment, a first woven textile comprises from 170 to 200 ends per inch of warp yarns and from 100to 110 picks per inch of a core spun yarn (the core spun yarn being a weft of the first woven textile fabric) that is a roving-spandex yarn (e.g., the roving-spandex yarn 200 of
In another embodiment, a second woven textile comprises from 148 to 170 ends per inch of warp yarns and from 88 to 100 picks per inch of a core spun yarn (the core spun yarn being a weft of the second woven textile fabric) that is a roving-spandex yarn (e.g., the roving-spandex yarn 200 of
In yet another embodiment, a third woven textile comprises from 170 to 200 ends per inch of warp yarns and from 70 to 80 picks per inch of a core spun yarn (the core spun yarn being a weft of the third woven textile) that is a poly-spandex yarn (e.g., the poly-spandex yarn 100 of
In yet another embodiment, a fourth woven textile comprises from 148 to 170 ends per inch of warp yarns and from 88 to 100 picks per inch of a core spun yarn (the core spun yarn being a weft of the woven textile) that is a poly-spandex yarn (e.g., the poly-spandex yarn 100 of
The poly-spandex yarn 100 and/or the roving-spandex yarn 200 may be used as a feed yarn for a loom apparatus to form a woven textile (e.g., any of the first woven textile, the second woven textile, the third woven textile, and the fourth woven textile disclosed above). In one preferred embodiment, the loom apparatus is an air jet loom apparatus such as a Picanol Omni Plus® or a Picanol Omni Plus® 800. In the air jet loom apparatus, a picking cycle should be completed as quickly as possible during a weft insertion event. For example, if a normal weft insertion would begin at a pick departure of 75° and end with a pick arrival at 255°, the air jet loom apparatus should be adjusted for the a pick departure of 80° and a pick arrival of 245°. A drive time of a main valve and a relay valve may be increased for usage of a spandex weft. For example, the drive time of the a main valve may be increased from 90° to 150° and the drive time of the relay valve may be increased from 70° to 125°. A pressure of a main nozzle may be increased from 4.5 bars to 5.5 bars, and a pressure of a set of relay nozzles may be increased from 5 bars to 6 bars. For the air jet loom apparatus of Picanal brand, an ELCA holding pressure may be 1.5kg/cm3 maximum.
A holding pressure of a main nozzle MB (Main Breeze) may be set to 150 KPa, and a tandem nozzle holding pressure may be set per a spandex weft requirement of a manufacturer of the looming apparatus. Additionally, one or more extra instances of the relay nozzle may be added near an end of a side selvedges of the woven textile, after a first filling detector. The extra instance of the relay nozzle may keep the poly-spandex yarn 100 and/or the roving-spandex yarn 200 at a required tension at the end of a picking cycle of the air jet loom apparatus. The loom apparatus may be set up in almost any of a type of weave, but in one preferred embodiment the type of weave used to form the first woven fabric, the second woven fabric, the third woven fabric, and/or the fourth woven fabric may be a sateen weave or a plain weave.
The woven textile that results from the use of the poly-spandex yarn 100 and/or the roving-spandex yarn 200 may be used to form a variety of useful and enhanced products. In one or more primary embodiments, the fabric may be used to for a bedding (e.g., a bed sheet, a pillow case, a duvet cover). The woven textile fabric may increase a sleep experience for several reasons. One reason may be that the woven textile comprised of the poly-spandex yarn 100 and/or the roving-spandex yarn 200 may lend a global stretch effect to the bedding. A lack of wrinkles is associated with a positive sleeping experience. Traditional bed sheets attempt to diminish wrinkles by using elastic bands around the corners of the bed-sheet, two edges of the bed sheet and/or the entire parameter of the bed-sheet, but no stretch effect is imparted to the bed sheet itself. In contrast, the bedding made from poly-spandex yarn 100 and/or the roving-spandex yarn 200 may be able to stretch over the surface of the bed sheet, which may increase comfort as a result of the uniform surface under constant tension from two opposite edges of the sheet.
Another benefit may be that the woven textile comprising poly-spandex yarn 100 and/or the roving-spandex yarn 200 may provide increased comfort as the weight of a person on top of the bed-sheet causes a stretching action in the direction of the core-spun yarn (e.g., the weft), which may temporarily increase the distance between a set of perpendicular yarns forming the weft, creating an enhanced airflow. The enhanced airflow may, among many benefits, cause the bed-sheet to feel cooler and may allow moisture or sweat to dry faster, further causing the comfort against the human skin. In one respect, if the thread count of the bed-sheet textile is defined as the number of yarns in both one inch of the warp direction and one inch of the weft direction when a fabric of the bed-sheet is in a native state, the thread count may decrease when a human weight is placed on, or moves over, the surface of the be bed-sheet due to the stretching of the fabric. However, in this instance a dynamic decreased in thread count experienced in an in-use state, rather than decrease comfort, may increase comfort by increasing a breathability of the bed sheet. Furthermore, no decrease in comfort may occur because the diameter of a core spun weft and a warp of the woven textile do not substantially change.
The advantages of the enhanced bedding are illustrated in
In the embodiment of
In operation 412, a spandex core may be drawn from a spandex bobbin to become associated with the oriented polyester yarn at a supporting guide located between the friction twisting unit and the intermediate roller. In operation 414, both the spandex core and the oriented polyester yarn may be drawn through an intermingling jet. In operation 416, the oriented polyester yarn may be texturized using the intermingling jet using a hot air punching technique. In operation 418, the oriented polyester yarn may be twisted around the spandex core using at least one of the intermingling jet and the friction twisting unit. In operation 420, the oriented polyester yarn and the spandex core may be drawn through a NFR roller after the intermingling jet. Finally, in operation 422, the oriented polyester yarn and the spandex core may be heated using a secondary heater to form the core spun yarn.
