Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of textiles, in particular to a three-dimensional jacquard textured gauze crepe. Background Art
[0002] As people's living standards continue to improve, people are paying more and more attention to the comfort of contact between the body and fabrics, as well as the aesthetics of the fabrics, for home textiles, clothes and other fabrics that come into contact with the body or have aesthetic requirements.
[0003] With the development of textile technology and materials, crepe fabrics have emerged. These fabrics feature a pleated surface structure, providing increased comfort when in contact with the body. The pleated structure also creates a three-dimensional feel and aesthetically pleasing aesthetics. Conventional crepe fabrics are made from a double-layered gauze blank that is sand-washed or water-washed to impart a wrinkled feel. However, since the pleated structure is achieved solely through water and sand washing, crepes produced using this method often suffer from a lack of wrinkle quality. Utility Model Content
[0004] The utility model provides a three-dimensional jacquard texture gauze crepe, which is used to solve the technical problem of insufficient wrinkle feeling of the crepe in the prior art.
[0005] The utility model provides a three-dimensional jacquard texture gauze crepe.
[0006] A three-dimensional jacquard gauze crepe comprises warp yarns and weft yarns, wherein the warp yarns and the weft yarns form a single-layer structure at some locations and a layered structure at other locations, wherein the layered structure comprises a surface layer and an inner layer, wherein at least part of the weft yarns of the inner layer are elastic yarns, so that the elastic shrinkage capacity of the inner layer is greater than that of the surface layer, and the three-dimensional jacquard gauze crepe has a pleated structure at least on the surface layer.
[0007] In one technical solution, the number of weft yarns in the inner layer is smaller than the number of weft yarns in the outer layer.
[0008] In one technical solution, the elastic yarn is cotton spandex yarn.
[0009] In a technical solution, the intervals between the weft yarns of the inner layer along the warp direction are greater than the intervals between the weft yarns of the surface layer along the warp direction.
[0010] In a technical solution, along the thickness direction of the three-dimensional jacquard texture gauze crepe, the projection of the weft yarns of the inner layer and the projection of the weft yarns of the surface layer are distributed at intervals.
[0011] In one technical solution, the ratio of the number of weft yarns in the inner layer to the number of weft yarns in the outer layer is 1:3.
[0012] In one technical solution, the number of warp yarns in the surface layer is equal to the number of warp yarns in the inner layer.
[0013] In one technical solution, the single-layer structure is an interwoven structure of N warp yarns and n weft yarns, where N≥2 and n≥2.
[0014] In one technical solution, the single-layer structure and the layered structure are alternately distributed at least in the weft direction.
[0015] In one technical solution, the layered structure accounts for 10% to 50% of the surface area of the three-dimensional jacquard texture gauze crepe.
[0016] Beneficial effects of the utility model:
[0017] According to the above-mentioned three-dimensional jacquard gauze crepe, since the inner weft yarn of the layered structure has elastic yarn, the elastic contraction capacity of the inner layer is greater than that of the surface layer. Therefore, after leaving the machine, the inner layer of the layered structure shrinks and the surface layer arches, so that a pleated structure is formed on the surface of the layered structure, that is, the three-dimensional jacquard gauze crepe has a pleated structure after leaving the machine.
[0018] The production process of three-dimensional jacquard gauze crepe needs to be washed and sand washed. Since the three-dimensional jacquard gauze crepe has a pleated structure after it comes off the machine, after subsequent water washing or sand washing, the pleated structure of the three-dimensional jacquard gauze crepe can be more prominent, with a better wrinkle effect.

Therefore, the specification and drawings are only for the purpose of clearly describing a particular embodiment and do not imply a required composition and / or sequence.

References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).
[0029] In the utility model, at least part of the weft yarns in the inner layer of the layered structure of the three-dimensional jacquard texture gauze crepe are elastic yarns, so that the elastic contraction capacity of the inner layer is greater than that of the surface layer. After the three-dimensional jacquard texture gauze crepe comes off the machine, the elastic contraction of the inner layer causes the surface layer to arch, forming a pleated structure on the surface of the layered structure.
[0030] Such three-dimensional jacquard texture gauze crepe already has a pleated structure before water washing or sand washing after it comes off the machine. Then, after water washing and sand washing, the three-dimensional jacquard texture gauze crepe can have a better crepe feeling.
[0031] An embodiment of the three-dimensional jacquard texture gauze crepe in the utility model:
[0032] Please refer to Figure 1 The three-dimensional jacquard gauze crepe fabric includes warp yarns and weft yarns, and has an alternating single-layer structure 100 and a layered structure 200, that is, the warp yarns and weft yarns form a single-layer structure 100 at some locations and a layered structure 200 at other locations. It should be noted that the finished three-dimensional jacquard gauze crepe fabric has a larger fabric surface. Figure 1The fabric structure of only part of the three-dimensional jacquard gauze crepe is shown. In a larger fabric area of the three-dimensional jacquard gauze crepe, there are more single-layer structures 100 and layered structures 200.
[0033] Please refer to Figure 2 , Figure 2 This is a partial weft-wise cross-sectional diagram of an embodiment of a three-dimensional jacquard gauze crepe. The layered structure 200 is specifically a two-layer structure, comprising a surface layer 201 and an inner layer 202. The inner layer 202 is located to one side of the surface layer 201. In some other embodiments, there may be other layers between the inner layer and the surface layer. Of course, the inner layer may also be a collective term for multiple layers located to one side of the surface layer. In this case, the multi-layer structure has more than two layers. The surface layer 201 is woven from surface warp yarns 2011 and surface weft yarns 2012, and the inner layer 202 is woven from inner warp yarns 2021 and inner weft yarns 2022. The inner weft yarns 2022 are elastic spandex yarns, and the surface weft yarns 2012 are 100% cotton yarns. This makes the elastic shrinkage capacity of the inner layer 202 along the weft direction greater than the elastic shrinkage capacity of the surface layer 201 along the weft direction. After the three-dimensional jacquard texture gauze crepe is unloaded from the machine, the inner layer 202 shrinks along the weft direction, causing the surface layer 201 to deform into a pleated structure, thereby forming a pleated structure on the surface of the layered structure 200.
[0034] In one embodiment, the number of inner weft yarns 2022 is less than the number of outer weft yarns 2012, so as to ensure the elastic shrinkage of the inner layer 202, so that after the three-dimensional jacquard texture gauze crepe is unloaded from the machine, the inner layer 202 remains as flat as possible after elastic shrinkage.
[0035] Please refer to Figure 2 The ratio of the number of inner weft yarns 2022 to the number of surface weft yarns 2012 is 1:3. In some other embodiments, the ratio of the number of inner weft yarns 2022 to the number of surface weft yarns 2012 can be other ratios less than 1, such as 1:2, 1:4, etc. When the ratio is 1:2, some of the inner weft yarns 2022 can be set as elastic yarns, and the other inner weft yarns 2022 can be made of the same material as the surface weft yarns 2012. Regarding the ratio of the number of surface weft yarns 2012 to the inner weft yarns 2022, in some other embodiments, the ratio can be 1, or even the number of inner weft yarns 2022 can be greater than the number of surface weft yarns 2012. However, this will cause the inner layer to form a wrinkled structure after elastic contraction.
[0036] As those skilled in the art can understand, the purpose of arranging elastic yarn-type weft yarns in the inner layer 202 is to make the weft elastic shrinkage capacity of the inner layer 202 greater than the elastic shrinkage capacity of the surface layer 201. Based on this purpose, those skilled in the art can flexibly design the number and material of the weft yarns of the surface layer 201 and the inner layer 202. As long as a suitable difference in elastic deformation capacity can be achieved, the inner layer weft yarns 2022 can be entirely elastic yarns or partially elastic yarns.
[0037] As for the material of the elastic yarn, in some other embodiments, one or more elastic fibers, elastic nylon, elastic filaments, and other elastically deformable yarns may be added to cotton yarn.
[0038] For the positional relationship between the surface weft yarn 2012 and the inner weft yarn 2022, please refer to Figure 2 Because the number of inner weft yarns 2022 is less than the number of outer weft yarns 2012, the intervals between the inner weft yarns 2022 and the outer weft yarns 2012 along the warp direction are greater than the intervals between the outer weft yarns 2012 along the warp direction, minimizing wrinkling of the inner weft yarns 2022 during elastic contraction. Furthermore, when projected along the thickness direction of the three-dimensional jacquard gauze crepe, the projections of the inner weft yarns 2022 and the outer weft yarns 2012 are spaced apart. This prevents the layered structure 200 from being too sparse, thereby enhancing the line of sight blocking effect of the layered structure 200 and minimizing the visibility of objects covered by the three-dimensional jacquard gauze crepe through the layered structure 200. For example, when using this three-dimensional jacquard gauze crepe to make a quilt cover, the inner quilt core can be minimized from being visible through the layered structure 200.
[0039] Please refer to Figure 3 , Figure 3 This is a partial warp-wise cross-sectional view of an embodiment of the three-dimensional jacquard gauze crepe of the present invention. It can be seen that in the layered portion 200, the number of surface warp yarns 2011 of the surface layer 201 is the same as the number of inner warp yarns 2021 of the inner layer 202. In other embodiments, depending on actual performance requirements for the three-dimensional jacquard gauze crepe, the number of surface warp yarns 2011 in the layered portion 200 may be greater or less than the number of inner warp yarns 2021.
[0040] Please refer to Figure 2 and Figure 3 In the layered structure 200, the surface layer 201 and the inner layer 202 are both in an up-down structure, i.e., a one-warp-one-weft interwoven structure. This can prevent the layered structure 200 from being too sparse to a certain extent, and as mentioned above, improve the effect of the layered structure 200 in blocking vision. Figure 1 、 Figure 2 and Figure 3Outside the layered structure 200, the surface warp yarns 2011, surface weft yarns 2012, inner warp yarns 2021, and inner weft yarns 2022 are woven into a single-layer structure 100. The weft yarns have a repeat of four yarns, each of which contains one elastic weft yarn. The transition between the single-layer structure 100 and the layered structure 200 is a junction point 300.
[0041] In one embodiment, the single-layer structure 100 is an interwoven structure of two warp yarns and two weft yarns, which ensures that the single-layer structure 100 is flat and has an obvious sparse structure, so as to have good air permeability.
[0042] More specifically, in some embodiments, the single-layer structure 100 is a plain weave. In other embodiments, the single-layer structure can also be a combination of one or more weaves such as twill and satin. In other embodiments, the single-layer structure can also be a weave structure with both the number of weft yarns and the number of warp yarns greater than two, such as a three-warp-three-weft interwoven weave structure, a three-warp-four-weft interwoven weave structure, a four-warp-three-weft interwoven weave structure, etc. In general, under the premise of conforming to engineering practice and meeting usage requirements, the single-layer structure is an N-warp-n-weft interwoven weave structure, where N ≥ 2 and n ≥ 2. In some embodiments, if the application of the three-dimensional jacquard texture gauze crepe does not require high breathability, the single-layer structure can be a one-warp-one-weft interwoven weave structure.
[0043] Please refer to Figure 1 、 Figure 2 and Figure 3 In the weft direction, the single-layer structure 100 is arranged next to the layered structure 200. That is, the single-layer structure 100 and the layered structure 200 are arranged alternately in the weft direction. The elastic inner layer weft yarn 2022 also constitutes part of the weft yarn of the single-layer structure 100. The elastic yarn shrinks, which can also cause the single-layer structure to wrinkle. In some other embodiments, the single-layer structure and the layered structure can be arranged alternately only in the warp direction. In this case, the single-layer structure and the layered structure do not share any weft yarns. Of course, the single-layer structure and the layered structure can also be arranged alternately in both the warp and weft directions.
[0044] In the production of this three-dimensional jacquard gauze crepe, the smallest recurring unit of the weave is a single jacquard pattern return. The weft yarn 2022 of the inner layer is made of stretch yarn (i.e., cotton spandex), and the layered structure 200 forms the jacquard pattern on the fabric surface. The total area of the layered structure 200, or the jacquard pattern area, accounts for 10% to 50% of the fabric surface area, with the specific value determined based on actual needs. The warp yarns are either 30S / 1-80S / 1 single yarn or ply yarn, and the inner weft yarn 2022 is 30S / 1-80S / 1 + (20D-40D) spandex. The warp density is 100-173 ends / inch, and the weft density is 80-120 ends / inch. After the three-dimensional jacquard gauze crepe comes off the loom, the shrinkage of the inner layer 202 causes the outer layer 201 to deform into a pleated structure.
[0045] The following content takes 1:60S double-layer elastic three-dimensional jacquard gauze crepe as an example to introduce the production process of three-dimensional jacquard gauze crepe. The process flow is as follows:
[0046] Fabric structure design
[0047] Spinning - Weaving - Greige fabric inspection - Singeing - Washing, wrinkling and semi-bleaching - Dyeing - Stentering and setting - Pre-shrinking - Finished product inspection
[0048] 1. Spinning
[0049] Different yarns are used in the warp and weft directions, of which the warp yarn is 60S / 1 compactly spun yarn, and the weft yarn is a combination of two or more yarns. The weft yarn used for the surface layer is 40S / 1 compactly spun yarn, and the bottom weft yarn is 40S / 1 compactly spun yarn and 40S / 1+40D yarn alternately beaten.
[0050] 2. Weaving
[0051] The warp yarn density is designed to be 173 yarns / inch. The pattern design is based on the jacquard weaving equipment design with warp return positions of 18.5 / 37 / 74 cm. In this embodiment, both the warp return position and the weft return position are 18.5 cm.
[0052] The pre-weaving preparation work includes sizing the warp yarn, threading the warp yarn through the reed, and preparing for weaving on a large jacquard machine.
[0053] The fabric structure design is that the surface gauze and the inner layer (specifically the bottom layer) gauze of the layered structure (specifically the double-layer structure) are plain weave, which has relatively more interweaving points and a more stable structure; and the area ratio of the layered structure is designed to be about 15%, and the warp yarn arrangement is such that the ratio of the single-layer warp yarn: the inner-layer warp yarn is 1:1, and the ratio of the surface weft yarn: the inner-layer weft yarn is 3:1 or 2:1, that is, the surface layer beating density is higher than that of the bottom layer, and the surface layer presents a three-dimensional structural texture on the surface of the overall fabric structure, and the inner layer weft yarn is fed at intervals when beating, that is, elastic yarn, specifically cotton spandex yarn, which plays a shrinkage role, and the three-dimensional sense of the surface is more obvious. The double-layer structure part is all pattern texture, and the rest is a single-layer structure, that is, the warp and weft yarns of the double-layer structure are merged into the warp and weft yarns of the single-layer structure. The single-layer structure adopts a double-warp and double-weft heavy plain weave structure to reduce interweaving points, and the fabric structure is sparse and flat with good air permeability.
[0054] After washing, wrinkling and de-bleaching treatment, the singed grey fabric is folded into sections and bagged to avoid entanglement during the washing process. It is placed in an industrial washing machine, and 10-20 g / L of sodium hydroxide, 3-6 g / L of hydrogen peroxide, 0.5-2 g / L of dispersant and 0.1-0.5 g / L of hydrogen peroxide stabilizer are added. After fully dissolved, the temperature is set at 90-100°C and the operation state is operated for 90-120 minutes, followed by dehydration, washing and drying.
[0055] This process makes the wrinkle structure on the three-dimensional jacquard texture gauze crepe more obvious and prominent. In addition to forming a prominent wrinkle structure on the surface 201 of the layered structure 200, the single-layer structure 100 will also be deformed into a wrinkle structure because the weft yarn contains elastic threads.
[0056] The above examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. Those skilled in the art of the present invention can make some simple deductions, modifications or substitutions based on the concept of the present invention.
