[0001] The utility model relates to the technical field of textile fabrics, and more specifically, to a high-elastic moisture-absorbing composite fabric. Background Art

[0002] Composite fabrics are generally made of double or multiple layers of fabrics bonded together with adhesives, thereby improving the texture of the fabric and giving the composite fabric certain special functions.

[0003] Due to the multi-layer structure of composite fabrics, their elasticity is poor, which may cause a heavy and restrained feeling on the human body. In addition, composite fabrics usually have poor moisture absorption and breathability, causing the wearer's sweat to be retained on the skin surface, affecting the wearing comfort. Therefore, a new structure is proposed to solve the problem of poor elasticity and moisture absorption of some composite fabrics. Utility Model Content

[0009] The utility model is further configured as follows: the moisture-conducting lines are formed by twisting strands of polypropylene special-shaped fibers with Y-shaped cross-sections into bundles.

[0010] The utility model is further configured as follows: the knitting density of the elastic outer layer is less than the knitting density of the moisture-absorbing inner layer.

[0011] The utility model is further configured as follows: the hygroscopic inner layer is woven from hygroscopic yarns, and the elastic outer layer is woven from elastic yarns.

[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] Example:

[0023] like Figure 1-Figure 4As shown, the high elastic hygroscopic composite fabric comprises a hygroscopic inner layer 1 and an elastic outer layer 2 which are fixedly connected to each other by sewing yarns, a plurality of hygroscopic parts 3 are fixed to the side of the hygroscopic inner layer 1 close to the elastic outer layer 2 by sewing with a sewing machine, a plurality of strands formed by viscose fibers 8 are woven and cut to form a square hygroscopic part 3, the viscose fibers 8 have good hygroscopicity, the hygroscopic part 3 accelerates the absorption of liquid on the skin surface, the hygroscopic part 3 supports the hygroscopic inner layer 1 and the elastic outer layer 2 to form a breathable cavity, and the flowing air can flow better between the fabrics and take away heat The moisture conducting component 4 is formed by weaving a plurality of strands of polypropylene shaped fibers 7 with a Y-shaped cross-section, stacking and sewing them in multiple layers, and the moisture dissipation characteristics of the polypropylene shaped fibers 7 are utilized to ensure that the moisture conducting component 4 has a stable moisture conducting performance. The moisture absorbing component 3 and the moisture conducting component 4 are sewn together by a sewing machine. The side of the moisture conducting component 4 away from the moisture absorbing component 3 is hot-pressed by a hot press to form a plurality of arc grooves 6. A plurality of I-shaped cracks are formed on the elastic outer layer 2 at positions corresponding to the moisture conducting component 4 by laser cutting. The height of the moisture conducting component 4 is greater than the thickness of the elastic outer layer 2. 4 is smaller than the width of the slit. When the hygroscopic inner layer 1 and the elastic outer layer 2 are stacked together, the moisture conducting member 4 passes through the slit, so that the fabrics on both sides of the slit expand outward with the moisture conducting member 4. A plurality of moisture conducting lines 5 are sewn on the elastic outer layer 2 along the length direction of the groove 6. The groove 6 limits the moisture conducting line 5, ensuring that the moisture conducting line 5 can smoothly expand outward and fix the fabrics on both sides of the slit. The moisture conducting line 5 is formed by twisting the strands of polypropylene shaped fibers 7 with a Y-shaped cross section into bundles. The moisture conducting line 5 is in an 8-shaped direction and penetrates from the side of the hygroscopic inner layer 1 away from the hygroscopic member 3 and penetrates through the hygroscopic member 3 and the moisture conducting member. 4 passes through the slit and then passes back to the moisture-absorbing inner layer 1 through the elastic outer layer 2 on both sides of the slit. The moisture-conducting lines 5 directly contact the skin to enhance the absorption, conduction and diffusion of the liquid. Through the above-mentioned sewing method, the fabrics on both sides of the slit are folded and fit the elastic outer layer 2, thereby enhancing the overall moisture dissipation and breathability of the fabric. The weaving density of the elastic outer layer 2 is less than that of the moisture-absorbing inner layer 1. Compared with the elastic outer layer 2, the moisture-conducting ability of the moisture-absorbing inner layer 1 is stronger than that of the elastic outer layer 2. The liquid is guided from the moisture-absorbing inner layer 1 to the elastic outer layer 2 and can quickly diffuse and evaporate, thereby improving the moisture absorption and quick-drying effect of the fabric.

[0024] like Figure 1 and Figure 3 As shown, the hygroscopic inner layer 1 is woven from hygroscopic yarn 9, which includes a core yarn and a covering yarn. The core yarn is twisted by a plurality of viscose fibers 8, and the covering yarn is twisted by a plurality of polypropylene shaped fibers 7 with a Y-shaped cross-section. The covering yarn is spirally wound around the outside of the core yarn. There are many hydrophilic genes on the cellulose macromolecules of the viscose fiber 8, which best meets the physiological needs of human skin. The polypropylene shaped fiber 7 with a Y-shaped cross-section has the advantages of being fluffy and having good water transport properties, and can quickly absorb liquid on the skin.

[0025] like Figure 1 and Figure 4 As shown, the elastic outer layer 2 is woven from elastic yarns 10, and the elastic yarns 10 are twisted after being formed into strands by a plurality of spandex fibers 11 and a plurality of polyester shaped fibers 12 with a C-shaped cross section through a twisting machine. The spandex fibers 11 have high elasticity and softness, and can stretch and retract without losing their shape, so that the elastic yarn 10 has a strong stretchability, and thus the elastic outer layer 2 can return to its original shape in time when pulled by external force, and is not easily deformed. The polyester shaped fibers 12 with a C-shaped cross section, as chemical fibers, not only have good elasticity, but also have a plurality of grooves formed on their outer peripheral walls to ensure the transfer efficiency of the elastic yarn 10 to sweat, and utilize the unidirectional moisture conduction function of the polypropylene fiber to the polyester fiber to ensure that the liquid in the hygroscopic inner layer 1 can flow better to the elastic outer layer 2.

[0026] like Figure 1-Figure 4 As shown, when it is necessary to make the fabric, firstly, a plurality of viscose fibers 8 and polypropylene shaped fibers 7 with a Y-shaped cross-section are placed in a twisting machine to form strands, which are then twisted to form hygroscopic yarns 9. The hygroscopic yarns 9 are then woven by an air jet loom to form a hygroscopic inner layer 1. A plurality of hygroscopic components 3 are fixed to the side of the hygroscopic inner layer 1 close to the elastic outer layer 2 by gluing or sewing with a sewing machine. The strands formed by the plurality of viscose fibers 8 are woven and cut by a cutting machine to form square hygroscopic components 3. A plurality of polypropylene shaped fibers 7 with a Y-shaped cross-section are placed in a twisting machine and twisted to form strands. The strands are then woven by an air jet loom to stack the fabrics in multiple layers and then sewed to form a hygroscopic component 4. The hygroscopic component 3 and the hygroscopic component 4 are sewed together by a sewing machine. The side of the hygroscopic component 4 away from the hygroscopic component 3 is hot-pressed by a hot press to form a plurality of arc grooves 6. A plurality of spandex fibers 11 are placed in a twisting machine and twisted to form a core yarn. The C-shaped polyester shaped fiber 12 is put into a twisting machine for twisting to form a covered yarn, the core yarn and the covered yarn are spirally wound through a spindle spinning process to form an elastic yarn 10, and then the elastic yarn 10 is woven through a jet loom to form an elastic outer layer 2, and a plurality of I-shaped cracks are formed on the elastic outer layer 2 at positions corresponding to the moisture conducting member 4 through laser cutting, the elastic outer layer 2 and the moisture absorbent inner layer 1 are sewn together through a sewing machine, the moisture conducting line 5 is formed by forming strands of polypropylene shaped fibers 7 with a Y-shaped cross-section and twisted into bundles, and the moisture conducting line 5 is sewn on the elastic outer layer 2 along the length direction of the groove 6 through a sewing machine, the moisture conducting line 5 is in an 8-shaped direction, penetrates from the side of the moisture absorbent inner layer 1 away from the moisture absorbent member 3, penetrates the moisture absorbent member 3 and the moisture conducting member 4, and then passes through the crack and then passes back to the moisture absorbent inner layer 1 from the elastic outer layer 2 on both sides of the crack, and the fabrics on both sides of the crack are folded when the moisture conducting line 5 is sewn, so that it is folded and fits the elastic outer layer 2, and finally the fabric is formed.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
