This disclosure is directed to surface covering articles (e.g., tufted, woven, or knitted surface covering articles) comprising yarns (e.g., engineered yarn structures) having sections with different aesthetic characteristics, and systems and methods for making said yarn and said articles. The yarns can be associated with a primary backing. In some examples, the yarns can be tufted through, woven through, or knitted through the primary backing.
Yarn can be tufted, woven, or knitted into a backing to form surface covering articles, such as, for example, carpet. In order to prevent noticeable flaws in the article, yarns must either (1) be uniform (to avoid variations from uniformity that lead to undesirable looks such as streaks); or (2) have a particular, consistent pattern (to avoid visible deviations from said pattern that are identifiable as a flaw). Both alternatives are associated with their own costs and lead to waste when uniformity and/or pattern requirements are not met.
Moreover, leftover yarn is typically a waste product having a cost associated with disposal thereof Accordingly, a use for small batches of leftover yarn is desirable.
Yarns can be dyed along their lengths according to a method called “space dying.” However, these space-dyed yarns have long (several centimeter) transitions between dyed sections that can look undesirable in tufted articles. Further, space dying yarn is an expensive process.
Disclosed herein is an article comprising a backing and a plurality of yarns tufted, woven, or knitted through the backing, each yarn defining at least one aesthetic characteristic. The at least one aesthetic characteristic can comprise one or more of luster, color, size, physical attribute associated with material type, or texture. At least one yarn of the plurality of yarns can comprise an engineered yarn structure comprising a first yarn section and a second yarn section. The engineered yarn structure can comprise a transition junction that comprises commingled portions of the first yarn section and the second yarn section. The transition junction can have a length of less than 1 millimeter. The first yarn section can have a first type of a first aesthetic characteristic of the at least one aesthetic characteristic, and the second yarn section can have a second type of the first aesthetic characteristic that is different from the first type. Optionally, the first and second yarn sections can correspond to respective yarn segments that are joined together via the transition junction.
In one aspect, a method can comprise tufting, weaving, or knitting a plurality of yarns through a backing. Each yarn can define at least one aesthetic characteristic, wherein the at least one aesthetic characteristic comprises one or more of luster, color, size, physical attribute associated with material type, or texture. At least one yarn of the plurality of yarns can comprise an engineered yarn structure comprising a first yarn section and a second yarn section. The engineered yarn structure can comprise a transition junction that comprises commingled portions of the first yarn section and the second yarn section. The transition junction can have a length of less than 1 millimeter. The first yarn section can have a first type of a first aesthetic characteristic of the at least one aesthetic characteristic, and the second yarn section can have a second type of the first aesthetic characteristic that is different from the first type. Optionally, the first and second yarn sections can correspond to respective yarn segments that are joined together via the transition junction.
A method can comprise tufting, weaving, or knitting a plurality of yarns through a backing. A first yarn of the plurality of yarns can comprise an engineered yarn structure comprising a first yarn section and a second yarn section. The engineered yarn structure can comprise a transition junction that comprises commingled portions of the first yarn section and the second yarn section. The transition junction can have a length of less than 1 millimeter. The first yarn section can have a first type of a first aesthetic characteristic selected from luster, color, size, physical attribute associated with material type, or texture. The second yarn section can have a second type of the first aesthetic characteristic that is different from the first type.
In one aspect, a method can comprise forming a yarn comprising an engineered yarn structure comprising a first yarn section and a second yarn section. The engineered yarn structure can comprise a transition junction that comprises commingled portions of the first yarn section and the second yarn section.

For example, a plurality of single end yarns can be twisted together to form a plied yarn (e.g., a two-ply yarn can include two single end yarns that are twisted together). Each single end yarn can be formed from at least one filament (optionally, a plurality of filaments). Thus, within a multiple end yarn, each single end yarn that makes up the multiple end yarn can include a respective filament or plurality of filaments.
Yarn with Different Aesthetic Characteristics along Yarn Length
Disclosed herein with reference to
The yarn 10 can define one or more aesthetic characteristics. The one or more aesthetic characteristics can comprise one or more of a color, a luster, a size (e.g., a diameter and/or a number of fibers), a physical attribute associated with material type, or a texture. In further aspects, the at least one aesthetic characteristic can be a function of a polymer type(s) and/or a shrinkage rate. Each yarn section (e.g., the first, second, and third sections 12, 14, 18) can have a respective type of each aesthetic characteristic associated therewith. For example, the first yarn section 12 can have a first type of a first aesthetic characteristic, and the second yarn section 14 can have a second type of the first aesthetic characteristic. The third yarn section 18 can have a third type of the first aesthetic characteristic. In one example, the first aesthetic characteristic is a color. Thus, the first yarn section 12 can have a first color, and the second yarn section 14 can have a second color. In another example, the first aesthetic characteristic can be a luster. In this example, the first yarn section 12 can have a first luster, and the second yarn section 14 can have a second luster. In some examples, each yarn section can define a first aesthetic characteristic and a second aesthetic characteristic. In some aspects, the first and second yarn sections 12, 14 can have different types of the first aesthetic characteristic. In further aspects, the first and second yarn sections can further have the same or different types of the second aesthetic characteristic.
Each yarn section can comprise a plurality of fibers. The transition junction 16 can be formed by splicing (e.g., air splicing) the first yarn section to the second yarn section. Although air splicing is one specific method for joining (and commingling) the yarn sections, it is contemplated that any conventional splicing or yarn joining method can be employed. In addition to, or as an alternative to air splicing, it is contemplated that the transition junctions can be formed by wrap splicing, mechanical knotting, twisting, entanglement (e.g., air entanglement), or combinations thereof. Accordingly, the transition junction 16 can comprise fibers of the first yarn section 12 commingled with fibers of the second yarn section 14. Thus, the transition junction 16 can comprise aesthetic characteristics associated with each of the first yarn section and the second yarn section. Thus, unlike conventional yarn splicing, wherein yarns of the same aesthetic characteristics are joined, the adjacent yarn sections can have different aesthetic characteristics, with the different aesthetic characteristics mixed within each transition junction.
Optionally, the yarn 10 can comprise sequential yarn sections that are joined at respective transition junctions and that alternate between the first and second type of the first aesthetic characteristic. Thus, the first and third yarn sections 12, 18 can share the same type of first aesthetic characteristic, with the second yarn section 14 being different from the first and third sections. Optionally, the first and third yarn sections 12, 18 can be identical in terms of aesthetic characteristics. In further aspects, the first aesthetic characteristic of the third yarn section can be a third type that is different from the respective first aesthetic characteristics of the first and second yarn sections 12, 14.
In some aspects, each section (e.g., the first, second, and third yarn sections 12, 14, 18) can have the same length. In further aspects, each yarn section can have a different length. In yet further aspects, some yarn sections can have the same length, and other yarn sections can have a different length. For example, the first yarn section 12 can have a first length L1, the second yarn section 14 can have a second length L2, and the third yarn section 18 can have a third length L3. Optionally, the first length L1 can be different from the second length L2. It is contemplated that the length of each yarn section can be randomly generated or selected during formation of the yarn 10 as further disclosed herein. Thus, each of the first length L1 and the second length L2 can be randomly generated. In various optional aspects, the length of each segment can be from about 800 meters to about 5000 meters, or from about 1000 meters to about 3000 meters.
In some optional aspects, the first aesthetic characteristic can be uniform along each yarn section. In other aspects, the first aesthetic characteristic can vary along at least one yarn section of the yarn. In some optional aspects, the first aesthetic characteristic can be uniform through a cross section of the yarn, which can contrast to, for example, yarn that has aesthetic characteristics imparted through dying of the yarn.

Optionally, yarn(s) 10 of the plurality of yarns 54 can further comprise a third yarn section 18 and a transition junction 20 that comprises commingled portions of the second and third yarn sections 14, 18. The yarn 10 can comprise any number of yarn sections (e.g., 2-20 sections or 3-10 sections). The transition junction 20 can have a length of less than ten millimeters, less than four millimeters, less than 2 millimeters, or less than one millimeter.
Each yarn section (e.g., the first, second, and third yarn sections 12, 14, 18) of the yarn(s) 10 of the plurality of yarns 54 can define at least one aesthetic characteristic. The at least one aesthetic characteristic can comprise one or more of a color, a luster, a size (e.g., a diameter or a number of fibers), or a texture. Each yarn section can have a respective type of each aesthetic characteristic associated therewith. For example, the first yarn section 12 can have a first type of a first aesthetic characteristic, and the second yarn section 14 can have a second type of the first aesthetic characteristic. When provided, the third yarn section 18 can have a third type of the first aesthetic characteristic. In one example, the first aesthetic characteristic is a color. Thus, the first yarn section 12 can have a first color, and the second yarn section can have a second color. In another example, the first aesthetic characteristic can be a luster. The first yarn section 12 can have a first luster, and the second yarn section can have a second luster. In some examples, each yarn section can define a first aesthetic characteristic and a second aesthetic characteristic. The first and second yarn sections 12, 14 can have different types of the first aesthetic characteristic. The first and second yarn sections 12, 14 can further have the same or different types of the second aesthetic characteristic. Optionally, yarn sections can differ in combinations of one or several aesthetic characteristics (e.g., color, luster, size, texture, polymer, or shrinkage). Optionally, the yarn sections can differ due to different material properties. For example, each yarn section can comprise, or consist of, or consist essentially of nylon 6, nylon 66, polyethylene terephthalate (PET), polypropylene, wool, or a combination thereof. Yarns made of different materials can have different aesthetic characteristics. Each yarn section can comprise any number of yarn plies (e.g., the number of yarn plies can be the same as or different from adjacent sections or other sections of the same yarn).
Optionally, the at least one yarn 10 of the plurality of yarns 54 can comprise sequential yarn sections that are joined at respective transition junctions and that alternate between the first and second type of the first aesthetic characteristic. Thus, for example, the first and third yarn sections 12, 18 of the at least one yarn 10 can share the same type of first aesthetic characteristic (e.g., a first type of the first aesthetic characteristic), with the first aesthetic characteristic of the second section 14 (e.g., a second type of the first aesthetic characteristic) being different from the first aesthetic characteristic of the first and third yarn sections 12, 18. Optionally, the first and third yarn sections 12, 18 can be identical in terms of aesthetic characteristics. In further aspects, the first aesthetic characteristic of the third yarn section 18 can be a third type that is different from the respective first aesthetic characteristics of the first and second yarn sections 12, 14.
Optionally, some (e.g., at least 20%, between 20% and 80%, or up to 80%) of the yarns or all the yarns of the article 50 can be in accordance with the yarn 10 as disclosed herein. Each respective yarn 54 can be tufted into a respective row using conventional tufting methods. Each yarn 54 can form tufts 55 in respective rows 58 that extend along a tufting axis 56. The article 50 can have a tufting axis 56 along which each row 58 extends. Similarly, in further aspects, each yarn 54 can be woven or knitted into respective rows using conventional weaving or knitting methods.
A yarn 10 can form a plurality of tufts 55 within a single row 58. The yarn 10 can be tufted by a single needle (e.g., a single needle of a needle bar) to form the plurality of tufts 55 within the single row 58. The tufts 55 of the single row 58 can comprise tufts formed from the first yarn section 12 and the second yarn section 14. In some aspects, a portion of the tufts 55 within a row 58 can consist of the first yarn section and a portion of the tufts of the row can consist of the second yarn section. The transition junction 16 can be disposed within the single row 58 and can be positioned at a location (e.g., within a tuft) between tufts 55 formed entirely from the first yarn section 12 and tufts formed entirely from the second yarn section 14. Optionally, in some aspects, the yarn 10 can further comprise a third yarn section and a second transition junction 20 formed by commingled portions of the second and third yarn sections. In these aspects, it is contemplated that a portion of the tufts 55 within the row 58 can consist of the third yarn section, with the second transition junction disposed within the row 58 and positioned at a location (e.g., within a tuft) between tufts formed entirely from the second yarn section and tufts formed entirely from the third yarn section. In exemplary aspects, the tufts 55 within each row 58 can be loop or cut pile or combinations of loop and cut pile.
In some aspects, the article 50 can have at least a first yarn 54a and a second yarn 54b, each having a structure in accordance with yarn 10. A first yarn section 60 of the first yarn 54a and a first yarn section 62 of the second yarn 54b can each have a respective starting location 64, 66 along the tufting axis 56 at which the respective sections begin. Optionally, the starting location 64 of the first yarn section 60 of the first yarn 54a can be axially offset from the starting location 66 of the first yarn section 62 of the second yarn 54b along the tufting axis 56. Alternatively, the starting locations 64, 66 can be in alignment or even or substantially even along the tufting axis 56.
In some aspects, each yarn section (e.g., the first, second, and third yarn sections 12, 14, 18) of one or more yarns of the plurality of yarns 54 can have the same length. In further aspects, each yarn section of one or more yarns of the plurality of yarns 54 can have a different length. In yet further aspects, some yarn sections of one or more yarns of the plurality of yarns 54 can have the same length, and other yarn sections of the same yarns can have a different length. For example, and with reference to
Optionally, adjacent (side-by-side or parallel) yarn sections of adjacent yarns can have different lengths. For example, the first and second yarns 54a,b can be adjacent each other. As shown, the first yarn 54a can have a first yarn section 60, and the second yarn 54b can have a second yarn section 62, wherein the first yarn section 60 and first yarn section 62 are adjacent. The first yarn sections 60 and 62 can optionally have different lengths. This can advantageously prevent patterns forming in the tufted, woven, or knitted article.
Method of Making Article Comprising Yarn with Different Aesthetic Characteristics along Yarn Length
Referring to
The method can comprise drawing the plurality of yarns from respective yarn packages 30, wherein at least one yarn package of the respective yarn packages comprises a plurality of sections, wherein each section of the plurality of sections differs from adjacent sections by the aesthetic characteristic. The yarn packages can, for example, be positioned on a creel that feeds the yarn of the yarn packages into a textile machine (e.g., a tufting machine, a weaving machine, or a knitting machine). In exemplary aspects, it is contemplated that each section of the plurality of sections of a yarn package 30 can correspond to a respective yarn section in a yarn 54.
Referring to
System and Method of Making Yarn with Different Aesthetic Characteristics along Yarn Length
A method can comprise forming a yarn 10 comprising an engineered yarn structure having a first yarn section 12 and a second yarn section 14,. The engineered yarn structure can comprise a transition junction 16 that comprises commingled portions of the first and second yarn sections. The transition junction can have a length of less than 4 millimeters, less than 2 millimeters, or less than 1 millimeter. The first yarn section 12 can have a first type of a first aesthetic characteristic, and the second yarn section 14 can have a second type of the first aesthetic characteristic that is different from the first type. Forming the yarn 10 can comprise splicing or otherwise securely coupling a first yarn segment with a second yarn segment (e.g., via a transition junction), wherein the first yarn segment has the first type of the first aesthetic characteristic, and wherein the second yarn segment has the second type of the first aesthetic characteristic. As further described herein, the first and second yarn sections can correspond to respective yarn segments that are joined together to produce a unitary yarn structure. Optionally, the first and second yarn segments can be leftover yarns (or portions of yarns) or yarn that is off specification from an intended specification. Thus, instead of disposing of leftover or off-specification yarns as waste, the first and second yarn segments can be formed into yarn 10.
In some optional aspects, an apparatus 100 can be configured to form the yarn 10. The apparatus 100 can assemble a plurality of yarns to form the yarn 10. The apparatus 100 can receive yarn from a yarn supply 102 comprising a plurality of yarns 104. The type of each aesthetic characteristic of each yarn 104 can optionally be uniform along its length. Each yarn 104 can optionally be leftover yarn or yarn that is off specification from an intended specification. The apparatus 100 can comprise an assembler 106 (e.g., an air splicer or a heat splicer) that is configured to selectively assemble yarns 104 from the yarn supply 102 to form a yarn 10. The apparatus 100 can optionally be in communication with a winder 108 that is configured to wind yarn from the apparatus 100 into a yarn package 30.
The apparatus 100 can be in communication with a controller 110 that determines which yarn 104 the apparatus draws from. Thus, the controller can determine, based on the yarns 104 in the yarn supply 102, the aesthetic characteristics of each segment of the yarn 10 by determining the yarn 104 from which the apparatus 100 is drawing. The controller 110 can further determine the length of each segment formed by the apparatus. Optionally, the controller 110 can be integral to the apparatus 100. In further aspects, the controller 110 can be separate from and in communication with the apparatus 100.
In some aspects, the controller 110 can use a randomization algorithm to randomly select between yarns 104 of the yarn supply 102, thereby causing the first section of at least one yarn of the at least one yarn to have a random type of aesthetic characteristic. In further aspects, the controller 110 can randomly generate a length of the yarn 104 to be formed into a segment of yarn 10. For example, a randomized time can be generated, and the apparatus 100 can draw yarn from a given yarn 104 for the randomized time.
It is contemplated that randomization of the aesthetic characteristic(s) of each yarn segment and/or length can be particularly advantageous in avoiding undesirable features in a tufted, woven, or knitted article. For example, it can be understood that if all lengths of segments of yarn are identical, patterns repeat along the article (along the tufting axis 56 in which each yarn forms tufts). Similarly, if ends of adjacent yarns are aligned and segments of adjacent yarns have the same length, thick lines that are perpendicular to the tufting axis 56 in which each yarn forms tufts would appear. That is, tufts formed from different-looking yarns next to each other appear to blend together to provide the appearance of a color gradient, whereas multiple yarns of the same aesthetic characteristic(s) across the tufted article transverse to the tufting axis 56 form a noticeable elongate portion that stands out and does not blend with the rest of the tufted article, and can be perceived as undesirable. Similarly, randomization of the aesthetic characteristic(s) can avoid unintentional streaks formed by adjacent yarns having the same aesthetic characteristic(s). Randomization of the aesthetic characteristic(s) can further avoid a need for an operator to order yarn packages in a particular order on a creel that feeds a tufting apparatus.
It can be understood that the disclosed systems and methods can form tufted, woven, or knitted articles having desirable aesthetic patterns. For example, as shown in
In view of the described products, systems, and methods and variations thereof, herein below are described certain more particularly described aspects of the invention.
