A face surface is predominantly composed of the set of primary warp yarns and a back surface is predominantly composed of the set of secondary warp yarns, while the plurality of warp yarns alternates between the set of primary warp yarns and the set of secondary warp yarns. A substantial percent of light incident to the woven shielding textile does not pass through.
Description
FIELD OF TECHNOLOGY

This disclosure relates generally to textiles and, more particularly, to a method, a device and/or a system of a woven shielding textile impervious to visible and ultraviolet electromagnetic radiation.


BACKGROUND

Shielding electromagnetic radiation in the visible range and the ultraviolet range may be desirable to create a dark environment during daylight hours or to prevent ionizing radiation, such as what may occur at wavelengths below 400 nanometers, from damaging biological tissue and/or other oxidation-sensitive materials.


Visible light and ultraviolet radiation may primarily penetrate woven textiles by penetrating through a set of pores that exist between an interlacing of a set of weft yarns and a set of warp yarns that make up the fabric. Some visible and ultraviolet radiation may also pass directly through the yarns of the woven textile or pass by indirect diffraction through the textile. A method for creating a light-impervious textile-like material that forms a barrier against electromagnetic radiation breach may including coating one or both sides of a woven textile in synthetic polymer (e.g., a rubber or a plastic) to fill the pores between the interlacing. However, the addition of a light-blocking coating such as a synthetic polymer may substantially decrease desirable mechanical properties of a native state of the woven textile as well as decrease breathability.


A person or an organization may require complete darkness for several reasons. Hotels and/or hospitals may be subject to a set of regulations requiring curtains over windows of a room to create a “blackout” environment that is substantially lacking in visible light and/or UV radiation. Specifically, a person may wish to have darkness so that they can rest with greater ease, or may even be subject to medical conditions that require complete darkness (e.g., sensitivity to light). The person may also wish to prevent visible and/or UV light from entering a location to decrease the heat absorbed by that area and therefore possible save money and energy to cool the area.


Additionally, darkness may be required in deployed military settings such as a command tent that may be set up in a desert. The command tent may have a set of communications and control equipment, and a display screen associated with the communications and control equipment may be difficult to see in a bright environments. Additionally, an exposure to UV light penetrating small pores in a tent fabric may, after a prolonged period, give rise to sun burn or even skin cancer in personnel within the tent despite the inclination that one is in the “shade” of the tent.


The synthetic polymer coating used to increase resistance to visible and UV light penetration may lack aesthetic appeal and create undesirable physical properties. For example, a woven curtain inside a hotel room may be coated on one side by the synthetic polymer. The woven curtain may look aesthetically pleasing from the interior of the hotel room (being that the woven side faces the inside of the hotel room), but may not look aesthetically pleasing as seen from the exterior of the hotel through the windows of the hotel room. Additionally, adding the synthetic polymer may decease flexibility, causing limited application (e.g., cannot be comfortably employed as apparel). Adding the synthetic polymer may also decrease breathability, for example causing the command tent to rapidly heat up being that it may be employed in the desert.

FIG. 1 is an interlacing diagram 150 showing a face surface 110 of a woven shielding textile 100, according to one embodiment. Particularly, FIG. 1 shows a woven shielding textile 100, a set of weft yarns 102, a plurality of warp yarns 104, a set of primary warp yarns 106, a set of secondary warp yarns 108, and a face surface 110, according to one embodiment.


The woven shielding textile 100 may be a textile which is a substantially impervious barrier to light 500, particularly electromagnetic radiation in the visible and/or ultraviolet electromagnetic radiation bands. According to one embodiment, the woven shielding textile 100 is made of a set of yarns that are interlaced by a loom apparatus. The loom apparatus may be, for example, an air jet loom (e.g., a Picanol Omni Plus®, a Picanol Omni Plus® 800), a loom with a rapier loom, etc. In various embodiments, the woven shielding textile 100 may be described as a woven multi layer fabric, the surfaces of which are primarily comprised of warp yarns (e.g., on both the face and the back). Such a textile would be described as “warp faced”. In the context of the present description, the face surface 110 refers to one side of the woven shielding textile 100.


The set of weft yarns 102 may be the crosswise yarns on a loom over and under which other yarns (e.g. warp yarns, etc.) are passed to make a textile. In the context of the present description, a yarn may refer to a spun thread suitable for the production of textiles. The set of weft yarns 102 may also be referred to as “picks.”


The plurality of warp yarns 104 may be a collection of yarns that run lengthwise on a loom which are interwoven with weft yarns to form a textile. In various embodiments, the plurality of warp yarns 104 may be divided into two sets: the set of primary warp yarns 106, and the set of secondary warp yarns 108. In one embodiment, the primary and secondary warp yarns may be substantially identical. In another embodiment, the primary and secondary warp yarns may differ from each other in aspects which may include, but are not limited to, weight, color, and/or material. In various embodiments, the weft yarns and/or the warp yarns may be thermoplastic yarns. In one preferred embodiment, the thermoplastic may be continuous-filament polyester having multiple filaments.


As shown in FIG. 1, the set of primary warp yarns 106 and the set of secondary warp yarns 108 are selectively interlaced with the set of weft yarns 102 to form the woven shielding textile 100. FIG. 1 is showing the face surface 110 of the textile, which is predominantly composed of the set of primary warp yarns 106.



FIG. 2 is an interlacing diagram 250 of a back surface 200 of the woven shielding textile 100 of FIG. 1, according to one embodiment. Particularly, FIG. 2 illustrates a back surface 200 of the woven shielding textile 100 of FIG. 1, in addition to the set of weft yarns 102, the plurality of warp yarns 104, the set of primary warp yarns 106, and the set of secondary warp yarns 108 of FIG. 1, according to one embodiment.


In the context of the present description, the back surface 200 refers to the side of the woven shielding textile 100 which is opposite the face surface 110. Similar to the interlacing diagram 150 of FIG. 1, FIG. 2 illustrates the selective interlacing of the plurality of warp yarns 104 with the set of weft yarns 102. FIG. 2 is showing the back surface 200 of the woven shielding textile 100, which is predominantly composed of the set of secondary warp yarns 108, in accordance with one embodiment.



FIG. 3 is an interlacing diagram 350 showing a weaving pattern 300 in the face surface 110 of FIG. 1, according to one embodiment. Particularly, FIG. 3 shows a weaving pattern 300, a first warp yarn 302, a first weft yarn 304, a second warp yarn 306, a second weft yarn 308, a third warp yarn 310, and a third weft yarn 312, all within the context of the woven shielding textile 100 of FIG. 1, according to one embodiment.


The weaving pattern 300 may be a repeated design formed by the selective interlacing of warp yarns and weft yarns. The first warp yarn 302, the second warp yarn 306, and the third warp yarn 310 may refer to specific warp yarns within a weaving pattern, whose relative position defines, at least in part, the repeated design. In various embodiments, the first warp yarn 302 and the third warp yarn 310 may belong to the set of primary warp yarns 106, while the second warp yarn 306 belongs to the set of secondary warp yarns 108.


The first weft yarn 304, the second weft yarn 308, and the third weft yarn 312 may refer to specific weft yarns within a weaving pattern, whose relative position defines, at least in part, the repeated design.


The weaving pattern 300 illustrated in FIG. 3 is defined by the interlacing of weft and warp, and represents a preferred embodiment. As shown, the first warp yarn 302, which belongs to the set of primary warp yarns 106, floats over six weft yarns before passing under the first weft yarn 304 in circle ‘1’. The second warp yarn 306, belonging to the set of secondary warp yarns 108, floats under six weft yarns before passing over the second weft yarn 308 at circle ‘2’. As shown, the first weft yarn 304 and second weft yarn 308 are separated by three weft yarns. A third warp yarn 310, belonging to the set of primary warp yarns 106, floats over six weft yarns before passing under the third weft yarn 312 at circle ‘3’. The second weft yarn 308 and the third weft yarn 312 are adjacent, and the third weft yarn 312 is one of the three weft yarns between the first and second weft yarns.


Similar weaving patterns may be used in other embodiments, which slightly differ from that illustrated in FIG. 3. For example, the warp yarns may float over/under more or less than 6 weft yarns. While the pattern shown in FIG. 3 represents a preferred embodiment, similar benefits may be obtained through slight variations, while also varying other properties such as appearance, texture, and flexibility.



FIG. 4 is an interlacing diagram 450 showing multiple pattern instances of the weaving pattern 300 of FIG. 3, according to one embodiment. Particularly, FIG. 4 shows a first pattern instance 402, and a second pattern instance 404, as well as the weaving pattern 300 of FIG. 3 in the context of the woven shielding textile 100 of FIG. 1, according to one embodiment.


The first pattern instance 402 may be a single instance of a repeating design created by a weaving pattern. The second pattern instance 404 may refer to a single instance of a weaving pattern 300 which overlaps, at least in part, with the first pattern instance 402, according to one embodiment. In FIG. 4, the first pattern instance 402 and the second pattern instance 404 overlap at circle ‘4’, such that the third weft yarn 312 of the first pattern instance 402 is also the first weft yarn 304 of the second pattern instance 404.



FIG. 5 is a woven shielding textile section view 550 showing the woven shielding textile 100 of FIG. 1 cut across a set of weft yarns 102, according to one embodiment. Particularly, FIG. 5 shows a light 500, in addition to the set of weft yarns 102, the set of primary warp yarns 106, the set of secondary warp yarns 108, and the face surface 110 of FIG. 1, as well as the back surface 200 of FIG. 2, according to one embodiment.


The light 500 may be electromagnetic radiation to which the woven shielding textile 100 may be exposed. In some embodiments, the light 500 may be sunlight 500. In one embodiment, the light 500 may comprise at least one of visible light and ultraviolet light.


As shown, the woven shielding textile 100 is warp-faced, according to one embodiment. The face surface 110 is predominantly composed of the set of primary warp yarns 106, while the back surface 200 is predominantly composed of the set of secondary warp yarns 108.



FIG. 6 is a construction parameter table 650 describing the woven shielding textile 100 of FIG. 1, according to various embodiments. Particularly, FIG. 6 shows a textile weight 600 (e.g. for embodiment Sr.No. 1, “280 GSM”), a warp weight 602 (e.g. for embodiment Sr.No. 1, “100Den”), a weft weight 604 (e.g. for embodiment Sr.No. 1, “300”), a linear density of warp yarns 606 (e.g. for embodiment Sr.No. 1, “308”), and a linear density of weft yarns 608 (e.g. for embodiment Sr.No. 1, “92”), according to one embodiment.


The textile weight 600 may be the weight of a textile, expressed in grams per square meter of the textile. The warp weight 602 may be the weight of a warp yarn, expressed in denier (i.e. the weight, in grams, of 9,000 meters of the yarn). The weft weight 604 may be the weight of a weft yarn, expressed in denier (i.e. the weight, in grams, of 9,000 meters of the yarn). Denier may roughly correlate with the yarn diameter. The linear density of warp yarns 606 may be the number of warp yarns in a woven textile within one inch, measured perpendicular to the warp yarns; it may be expressed in yarns per inch. The linear density of weft yarns 608 may be the number of weft yarns in a woven textile within one inch, measured perpendicular to the weft yarns; it may be expressed in picks per inch. In FIG. 6, “DD” may stand for dope dyed weft, although in one embodiment, the weft may not be dope dyed.


The construction parameter table 650 of FIG. 6 describes the woven shielding textile 100 in a variety of embodiments. The warp of the woven shielding textile 100 has a weight of between 50 denier and 100 denier. The weft of the woven shielding textile 100 has a weight of between 300 denier and 350 denier. The linearly density of the warp yarns in the woven shielding textile 100 is between 250 and 336 yarns per inch. The linear density of the weft yarns of the woven shielding textile 100 is between 57 and 118 picks per inch.


The woven shielding textile 100 may have a weight of between 180 GSM and 280 GSM. To manage a high density of the warp yarns in the final product (e.g., the woven shielding textile) relative the weft yarns, the warp yarns that are to be incorporated into the woven shielding textile 100 may be split into two warp beams that may be operated independently while fed into the looming apparatus. Specifically, the woven shielding textile 100 may be woven using a “double beam” weaving system, with the set of primary warp yarns 106 drawing from a first beam and the set of secondary warp yarns 108 drawn from a second beam. Each of the two warp beams may be synchronized such that a balanced tension in both the face surface 110 and the back surface 200 of the fabric results. Balancing the tension may provide stability of the woven shielding textile 100 during the weaving process. Each of the two warp beams may be driven by a servomotor, and a tension of the warp yarns drawn from each of the beams may be controlled by a load cell. Both of the load cells may be adjusted to further promote the balanced tension of the warp yarns within the looming apparatus.


The plurality of warp yarns 104, which may comprise the majority of the face surface 110 and of the back surface 200 of the woven shielding textile 100, may be over-dyed. In contrast, the set of weft yarns 102 of the woven shielding textile 100 may be made up of a dope dyed yarn. A yarn which is dope dyed may be a synthetic yarn where a polymer that comprises the synthetic yarn (e.g., polyester, etc.), before an extrusion process that forms the synthetic yarn, is mixed with a dye such that the extruded fibers that comprise the synthetic yarn have dye integrated into and therefore substantially permanently associated with them synthetic yarn (e.g., it cannot rub off, etc.). The weft yarn of the woven shielding textile 100, in one embodiment, may be a highly texturized polyester yarn.


In one embodiment, the woven shielding textile 100 may block between 90% and 100% of visible light. In the heavier end of the range of textile weights, the woven shielding textile 100 may block between 98% and 100% of visible light. In one embodiment, the woven shielding textile 100 may block between 90% and 100% of ultraviolet light.
