Description

Technical Field

[0001] This invention relates to the field of textile technology, and in particular to a partially elastic fabric and its weaving method. Background Technology

[0002] Currently, with the rapid development of science and technology, the application range of textile fabrics is becoming increasingly wide. Existing locally elastic textile materials require multiple post-processing steps to laminate another elastic textile fabric onto a non-elastic fabric to achieve the effect of localized elasticity. Composite fabrics are not ideal in terms of wash resistance, abrasion resistance, and hand feel. Furthermore, the splicing process requires cutting and sewing multiple pieces of fabric processed separately. During the cutting and sewing process, not only will the fabric shed yarns, but the sewing and splicing also requires leaving space, which is not only wasteful of materials but also relatively cumbersome and results in high weaving costs. Summary of the Invention

[0003] The purpose of this invention is to provide a partially elastic fabric and its weaving method, which can solve the problems of partially elastic textile materials being not wear-resistant and having unstable structures.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a partially elastic fabric, comprising a mesh body, wherein the mesh body comprises an embroidery layer, a textured layer, a functional yarn layer, and an elastic and reinforcing structural layer, wherein the embroidery layer is woven on the textured layer, the functional yarn layer is woven under the textured layer, and the elastic and reinforcing structural layer is disposed between the textured layer and the functional yarn layer and is woven to connect the textured layer and the functional yarn layer.

[0005] Furthermore, the yarn used in the embroidery layer is polyester, nylon, or cationic yarn; the yarn used in the texture layer is elastic or non-elastic yarn between 40D and 200D; the yarn used in the functional yarn layer is polyester filament or elastic yarn between 40D and 150D; and the yarn used in the elastic and reinforced structural layer is yarn of 100D or higher.

[0006] A locally elastic weaving method, using a warp knitting machine, includes the following steps:

[0007] Step S1: By using the lace comb transverse pressing mechanism, various three-dimensional patterns are woven on the top layer of the fabric to form an embroidery layer.

[0008] Step S2: Using a double Jacquard combing jacquard mechanism, a texture layer is woven by combining thin weave, thick weave, and mesh weave to form three-dimensional, planar, and mesh structures.

[0009] Step S3: Through the double ground comb loop forming mechanism, the two loop-forming ground combs each weave straight chain, variable chain, warp flat, double warp, warp segment structure, or cooperate to weave double ground comb structures such as pull loop, regular hexagonal net, etc. to form functional yarn layers.

[0010] Step S4: Through the ground comb weft insertion mechanism, one of the weft insertion type ground combs in the ground comb weft insertion mechanism only moves the back of the knitting needle laterally, but does not move the front of the knitting needle laterally, and acts as weft padding. It works in conjunction with the looping ground comb of the functional yarn layer to weave a regular mesh structure to form an elastic and reinforced structural layer.

[0011] Furthermore, the yarn guide bar transverse shift pressing mechanism is PB1-24, the base fabric double Jacquard guide bar loop forming jacquard mechanism is JB25-28, the double ground guide bar loop forming mechanism is GB29-30, and the ground guide bar weft insertion mechanism is GB31.

[0012] Furthermore, the yarn threading method of PB1-24 is full threading with passive warp feeding from the yarn rig; the yarn threading method of B25-28 is full threading with passive warp feeding from the yarn rig; the yarn threading method of GB29-30 is full threading with active warp feeding from the yarn head; and the yarn threading method of GB31 is full threading with active warp feeding from the yarn head.

[0013] Furthermore, the PB1-24 is a warped, fully combed 900D / 288F SD polyester semi-dull low-elastic yarn; the JB25-26 is a warped, fully combed 100D / 24F polyester matte low-elastic yarn; the JB27-28 is a warped, fully combed 150D / 36F polyester bright low-elastic twisted yarn; the GB29 is a warped, fully combed 100D / 36F polyester semi-dull high-strength filament; the GB30 is a warped, fully combed 100D / 36F polyester semi-dull high-strength filament; and the GB31 is a warped, fully combed 210D spandex.

[0014] Furthermore, the padding yarn number for JB25-26 is 0-1 / 2-1 / / or 2-1 / 1-2 / / , the padding yarn number for JB27-28 is 0-1 / 2-1 / / or 2-1 / 1-2 / / , the padding yarn number for GB29-30 is 1-0 / 0-1 / / , and the padding yarn number for GB31 is 0-0 / 3-3 / / .

[0015] The beneficial effects of this invention are as follows: Compared with the prior art, the purpose of this invention is to provide a locally elastic textile fabric and a weaving method that are woven in one piece, so that the fabric has excellent physical properties such as wash fastness and rubbing fastness. The textile material with locally elastic function of this invention has excellent physical properties such as wash fastness, rubbing fastness, tear resistance, and burst resistance. The textile fabric of this invention is woven in one piece, with a stable structure. The one-piece molding can reduce multiple subsequent processes, save raw materials, and reduce weaving costs. Moreover, the pattern changes are diverse during the weaving process, making it widely applicable to clothing, footwear, furniture and other fields. Attached Figure Description

[0021] The invention will now be further described with reference to the accompanying drawings.

[0022] Please see Figures 1 to 3 The present invention provides an embodiment of a partially elastic fabric, comprising a mesh body 1, wherein the mesh body 1 comprises an embroidery layer 7, a textured layer 4, a functional yarn layer 2, and an elastic and reinforcing structural layer 3, wherein the embroidery layer 7 is woven on the textured layer 4, the functional yarn layer 2 is woven under the textured layer 4, and the elastic and reinforcing structural layer 3 is disposed between the textured layer 4 and the functional yarn layer 2, and is woven to connect the textured layer 4 and the functional yarn layer 2.

[0023] Please continue reading. Figures 1 to 3 As shown, in another embodiment of the present invention, the yarn used in the embroidery layer 7 is polyester, nylon, or cationic yarn; the yarn used in the texture layer 4 is elastic or non-elastic yarn between 40D and 200D; the yarn used in the functional yarn layer 2 is polyester filament or elastic yarn between 40D and 150D; and the yarn used in the elastic and reinforced structural layer 3 is yarn of 100D or higher.

[0024] Please see Figures 1 to 3As shown, the present invention provides another embodiment: a partially elastic weaving method, using a warp knitting machine. This machine, from front to back, has four functional working lines: a yarn guide bar transverse pressing mechanism, a base fabric double Jacquard guide bar loop forming mechanism, a double ground guide bar loop forming mechanism, and a ground guide bar weft insertion mechanism. These four functional working lines perform different weaving movements sequentially within one revolution of the needle bed cam, combining to form a complete textile fabric. The method includes the following steps:

[0025] Step S1: Using a yarn guide bar transverse shifting and pressing mechanism, various three-dimensional patterns are woven into the top layer of the fabric to form an embroidered layer 7; patterns include, but are not limited to, trademarks and logos, which can reduce subsequent processing steps. Yarn raw materials include, but are not limited to, polyester, nylon, and cationic yarns; the yarn guiding mechanism is an electronic transverse shifting system, yarn guiding needles, carbon fiber needle guide bars, and stainless steel guide bar boxes; the warp feeding mechanism is a yarn frame type passive warp feeding.

[0026] Step S2: Using a double Jacquard combing jacquard mechanism, a texture layer 4 is woven, consisting of a combination of thin, thick, and mesh structures to form three-dimensional, planar, and mesh structures. By using different colors or materials for the front and back Jacquard layers, along with various Jacquard patterns, the fabric can have a richer appearance, feel, performance, and style. Furthermore, due to the small size of the Jacquard needles and the high quality requirements of the fabric, the Jacquard raw material is best used to be a 40D-200D elastic or non-elastic material. The yarn guiding mechanism is a Jacquard signal communication system, wireless communication electromagnetic Jacquard needles, and Jacquard yarn guiding combs. The warp feeding mechanism is a frame-type passive warp feeding.

[0027] Step S3: Using a double-comb loop-forming mechanism, two loop-forming combs each weave straight chain, varied chain, warp flat, double warp, and warp segment structures, or work together to weave double-comb structures such as loop-forming and hexagonal nets to form functional yarn layer 2; by combining raw materials of different thicknesses, materials, and functions, the physical properties of the fabric, such as abrasion resistance, folding resistance, tear resistance, and burst resistance, can be optimized. The performance and structural tests of products woven using this method are as follows: Figure 4 As shown, the fabric can have different functions, expanding the range of applications of the fabric. The yarn guiding mechanism is an electronic transverse system, a yarn guiding needle bar, and a stainless steel yarn guiding comb, while the warp feeding mechanism is a multi-segment warp beam type electronic warp feeding system.

[0028] Step S4: Through the ground comb weft insertion mechanism, one of the weft insertion type ground combs in the mechanism only performs the back-of-needle lateral movement of the knitting needles, not the front-of-needle lateral movement, acting as a weft pad. This works in conjunction with the loop-forming ground comb of the functional yarn layer 2 to weave a regular mesh structure, forming an elastic and reinforced structural layer 3. Further thickening and light-blocking with materials of 100D or higher, and the use of spandex or core-spun yarn, gives the fabric weft elasticity. The localized elasticity is provided by the combination of the elastic and reinforced structural layer 3, the texture layer 4, and the functional yarn layer 2.

[0029] Under electrical control, the machine's needle bed, driven by cams, sequentially weaves the yarns fed through the patterned yarn guide bar transverse movement pressing mechanism, the base fabric double Jacquard guide bar loop forming mechanism, the double ground guide loop forming mechanism, and the ground guide weft insertion mechanism into the knitting needles, completing one knitting cycle. After all the transverse movement elements in a pattern cycle are knitted, they are combined together to form a complete design pattern that repeats highly.

[0030] Please continue reading. Figures 1 to 3 As shown, in another embodiment of the present invention, the yarn guide bar transverse shifting and pressing mechanism is PB1-24, the base fabric double Jacquard guide bar loop forming jacquard mechanism is JB25-28, the double ground guide bar loop forming mechanism is GB29-30, and the ground guide bar weft insertion mechanism is GB31. PB1-24 is woven to form an embroidery layer 7, JB25-28 is woven to form a textured layer 4, GB29-30 is woven to form a functional yarn layer 2, and GB31 is woven to form an elastic and reinforced structural layer 3.

[0031] Please continue reading. Figures 1 to 3 As shown, in another embodiment of the present invention, the yarn threading method of PB1-24 is full threading with passive warp feeding from the yarn rig; the yarn threading method of B25-28 is full threading with passive warp feeding from the yarn rig; the yarn threading method of GB29-30 is full threading with active warp feeding from the yarn head; and the yarn threading method of GB31 is full threading with active warp feeding from the yarn head.

[0032] Please continue reading. Figures 1 to 3 As shown, in another embodiment of the present invention, the PB1-24 is a warped and fully combed 900D / 288FSD polyester semi-dull low-elastic yarn, the JB25-26 is a warped and fully combed 100D / 24F polyester matte low-elastic yarn, the JB27-28 is a warped and fully combed 150D / 36F polyester bright low-elastic twisted yarn, the GB29 is a warped and fully combed 100D / 36F polyester semi-dull high-strength filament, the GB30 is a warped and fully combed 100D / 36F polyester semi-dull high-strength filament, and the GB31 is a warped and fully combed 210D spandex.

[0033] Please continue reading. Figures 1 to 3As shown, in another embodiment of the present invention, the padding yarn number of JB25-26 is 0-1 / 2-1 / / or 2-1 / 1-2 / / , the padding yarn number of JB27-28 is 0-1 / 2-1 / / or 2-1 / 1-2 / / , the padding yarn number of GB29-30 is 1-0 / 0-1 / / , and the padding yarn number of GB31 is 0-0 / 3-3 / / . PB1-24 The pattern comb allows for arbitrary needle movement within the machine's permissible range without fixed yarn padding numbers. Different yarn padding numbers can create different textures and patterns. Combined with different raw materials, this makes the fabric suitable for more environments. JB25-28 The base fabric with double Jacquard combs moving 1-0 / 1-2 / / forms a texture layer 4 in a 2-plain fabric state. Moving 2-1 / 1-2 / / creates a lifting hole effect 6. GB29-30 Moving 1-0 / 0-1 weaves into a chain weave structure to form a functional yarn layer 2. Using some special raw materials, the fabric can have functions such as cooling, warmth, and odor resistance. GB31 Using elastic raw materials with 0-0 / 3-3 movements gives the fabric weft elasticity. Using non-elastic raw materials can reinforce the fabric. The local elastic area 5 is a lifting hole 6 structure woven by a double Jacquard comb loop weave mechanism on the base fabric. Texture layer 4 is composed of an elastic and reinforcing structural layer 3 made of elastic raw materials and a functional yarn layer 2 woven by a double-base comb loop weave mechanism.

[0034] Compared to existing technologies, the partially elastic fabric provided by this invention breaks through the limitation that existing elastic or non-elastic fabrics can only be woven and used separately. It realizes that in the case of integrated weaving, the same piece of fabric can have the process characteristics of both elastic and non-elastic fabrics at the same time. It solves the limitation of the composite process of elastic and non-elastic fabrics on the market, saves fabric costs, reduces the later sewing process, and enriches the design of fabrics.

[0035] The above description is only a preferred embodiment of the present invention and should not be construed as a limitation of this application. All equivalent changes and modifications made in accordance with the scope of the patent application of the present invention should be covered by the present invention.
