Description

Technical Field

[0001] The utility model relates to the technical field of textiles, and more specifically, it relates to a cool-sensation anti-sticking polyester fabric. Background Art

[0002] Polyester fabric is a kind of fabric woven by polyester fibers, which is a common chemical fiber clothing fabric in people's daily life. Polyester fiber is a synthetic fiber made by chemical polycondensation of organic dibasic acids and diols. It has excellent wrinkle resistance and shape retention, making the produced polyester fabric strong, durable, wrinkle-resistant and non-ironing. It is usually used to make home furnishing products such as clothes, bedding, and curtains.

[0003] However, the hygroscopicity and air permeability of polyester fibers are poor, so that the clothes made will produce a stuffy feeling when worn, and it is easy to sweat and the sweat produced cannot be adsorbed and removed by the clothes in time and stays on the skin surface, making the clothes easily stick to the skin surface by sweat, which affects the wearing comfort.

[0004] Therefore, a new solution is needed to solve the problem of poor hygroscopicity and air permeability of polyester fabric. Content of the Utility Model

[0005] Aiming at the deficiencies of the existing technology, the purpose of the utility model is to provide a cool-sensation anti-sticking polyester fabric, which aims to improve the hygroscopicity and air permeability of the polyester fabric through a new structural setting.

[0006] The above technical purpose of the utility model is achieved through the following technical solutions: The cool-sensation anti-sticking polyester fabric includes an inner layer and an outer layer fixedly connected to each other. A number of depressions one and a number of depressions two are respectively formed on both sides of the inner layer. An air-permeable space is formed between the depression one and the outer layer. A number of ventilation grooves arranged in an array are formed through the inner layer. The ventilation grooves are bent in a Z shape along their length directions together with the inner layer and are communicated with the air-permeable space and the depression two. A number of ventilation holes communicated with the air-permeable space are formed through the outer layer directly above the depression one.

[0007] The utility model is further arranged as follows: The depression one and the depression two are of the same size and are arranged alternately along the length direction of the inner layer. A number of the depression one and a number of the depression two on both sides of the inner layer are integrally formed by pleating at the ventilation grooves through an I-shaped pleat pressing process.

[0008] The utility model is further arranged as follows: A number of the ventilation grooves are all located at the adjacent bending parts in the thickness direction of the inner layer, and the length of the ventilation grooves is greater than the distance between the adjacent bending parts in the thickness direction of the inner layer.

[0009] The utility model is further arranged as follows: The area of the outer layer between the adjacent depression one abuts against the inner layer, and the abutting part of the inner layer and the outer layer is fixedly sutured by reciprocating wet-spreading yarns.

[0010] The present utility model is further configured such that: the outer layer is made by weaving moisture-dispersing yarns through a through-hole weave, and a plurality of the ventilation holes are integrally formed on the outer layer through the through-hole weave.

[0011] The present utility model is further configured such that: the moisture-dispersing yarn is made by helically winding a first strand around a second strand, the first strand is twisted from linen fibers, and the second strand is twisted from a polyester profiled fiber with a C-shaped cross-section.

[0012] The present utility model is further configured such that: the inner layer is made by weaving cool-sensation yarns through a plain weave, the cool-sensation yarn is made by helically winding a third strand around the second strand, and the third strand is twisted from viscose fibers.

[0013] In summary, the present utility model has the following beneficial effects: By making the polyester fibers profiled, larger voids and surface areas are obtained, thereby improving the moisture absorption and breathability of the polyester fibers. Viscose fibers have good moisture absorption and thermal conductivity. They can quickly absorb the sweat generated on the wearer's body surface and produce an evaporation heat absorption effect, quickly taking away the temperature of the body surface. The inner layer made by blending viscose fibers coated on the profiled polyester fibers can produce a cool feeling when in contact with the skin. By means of a plurality of depressions II, the contact area between the inner layer and the skin is reduced, and the gap and air circulation effect between the inner layer and the skin are increased. Linen fibers have strong moisture absorption and moisture dispersion properties, enabling the made outer layer to quickly disperse the moisture inside it, thereby maintaining the dryness of the polyester cloth and the skin, and avoiding the discomfort caused by the polyester cloth adhering to the skin due to sweat. The mutually connected plurality of ventilation holes, ventilation spaces, ventilation grooves and depressions II improve the air circulation effect between the inside and outside of the polyester cloth, and avoid the stuffy feeling when the made clothing is worn.

Specific implementation mode

[0020] The following combines the drawings and embodiments to describe the present utility model in detail.

[0021] Embodiment: The cool-sensation anti-sticking polyester fabric, as Figure 1 and Figure 5 shown, includes an inner layer 1 and an outer layer 2 that are fixedly connected to each other. The inner layer 1 is made by feeding the cool-sensation yarn 12 into an air-jet loom and weaving it in a plain weave pattern. The cool-sensation yarn 12 is made by helically winding a third strand 13 around a second strand 11 through the processing technology of ring spinning. The second strand 11 is twisted from polyester profiled fibers with a C-shaped cross-section. The polyester profiled fibers with a C-shaped cross-section are spun through a spinneret. By making the polyester fibers profiled, they obtain larger voids and surface areas, thereby improving the moisture absorption and breathability of the polyester fibers. The third strand 13 is twisted from viscose fibers through a twisting machine. Viscose fibers have good moisture absorption and thermal conductivity. It can quickly absorb the sweat generated on the wearer's body surface and produce an evaporation heat absorption effect, so that the inner layer 1 made of viscose fibers coated on polyester profiled fibers can quickly take away the body surface temperature when in contact with the skin, thereby generating a cool feeling and keeping the skin dry and comfortable.

[0022] As Figure 1 and Figure 2 shown, several first depressions 3 and several second depressions 4 are provided on both sides of the inner layer 1. The first depressions 3 and the second depressions 4 are of the same size and are arranged alternately along the length direction of the inner layer 1. By several second depressions 4, the contact area between the inner layer 1 and the skin is reduced, and the gap and air circulation effect between the inner layer 1 and the skin are increased. Several first depressions 3 and several second depressions 4 on both sides of the inner layer 1 are integrally formed after being pleated by a pleating machine in an I-shaped pleat pattern.

[0023] As Figure 1 and Figure 4 shown, the outer layer 2 is made by feeding the moisture-dispersing yarn 9 into an air-jet loom and weaving it in a porous weave pattern. The moisture-dispersing yarn 9 is made by helically winding a first strand 10 around a second strand 11 through the processing technology of ring spinning. The first strand 10 is twisted from linen fibers through a twisting machine. Linen fibers have strong moisture absorption and breathability. The densely distributed voids in the linen fibers can allow air to circulate better, so as to quickly disperse the moisture inside, so that the moisture absorbed in the inner layer 1 can be adsorbed by the outer layer 2 and quickly dispersed, thereby maintaining the dryness of the polyester fabric and the skin, and preventing the polyester fabric from adhering to the skin due to being wetted by sweat.

[0024] As Figures 1-3 shown, a plurality of air-permeable holes 8 arranged in an array are formed through the outer layer 2. The plurality of air-permeable holes 8 are integrally formed on the outer layer 2 by means of the weaving method of openwork tissue. The overall air permeability of the polyester fabric is further improved through the plurality of air-permeable holes 8. The plurality of air-permeable holes 8 are all located directly above the first recess 3. The outer layer 2 abuts against the area between the adjacent first recesses 3 of the inner layer 1. The abutting portion of the inner layer 1 and the outer layer 2 is fixedly stitched reciprocally by a sewing machine using moisture-dispersing yarn 9, so that an air-permeable space 6 communicating with the plurality of air-permeable holes 8 is formed between the inner peripheral wall of the first recess 3 and the side of the outer layer 2 close to the inner layer 1.

[0025] As Figures 1-3 shown, a plurality of strip-shaped ventilation grooves 7 arranged in an array are formed through the inner layer 1. The plurality of ventilation grooves 7 are formed through cutting by a cutting machine before the pleating process on the inner layer 1. Pleating is performed on the ventilation grooves 7 located on the inner layer 1 by a pleating machine, so that the plurality of ventilation grooves 7 are all located at the bent portions adjacent in the thickness direction of the inner layer 1. The ventilation grooves 7 are zigzag along their length directions after being bent together with the inner layer 1. The length of the ventilation grooves 7 is greater than the distance between the adjacent bent portions in the thickness direction of the inner layer 1, so that the ventilation grooves 7 communicate with the air-permeable space 6 and the second recess 4 at the same time. The air circulation effect between the inside and the outside of the polyester fabric is improved through the mutually communicating plurality of air-permeable holes 8, air-permeable space 6, ventilation grooves 7 and second recess 4. While further strengthening the moisture-dispersing performance of the polyester fabric, the produced clothes are prevented from generating a stuffy feeling when worn.

[0026] The above is only the preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
