Description

TECHNICAL FIELD

[0001] The utility model relates to textile technical field more specifically, it relates to moisture absorption and perspiration polyester composite fabric. BACKGROUND

[0002] Polyester fabric is a kind of chemical fiber fabric woven by polyester fiber, and polyester fiber is a synthetic fiber made of organic diacid and dihydric alcohol by chemical polycondensation, which has excellent wrinkle resistance and shape retention, so that the fabric made is firm and durable, wrinkle-free and ironing-free, and is widely used in the production of products such as clothing, bedding, home decorations, luggage, umbrella and tent.

[0003] However, the moisture absorption and air permeability of polyester fiber are relatively poor, so that the clothes made therefrom will feel stuffy when worn, and sweat is easy to produce and cannot be absorbed and dissipated by the clothes in time, which makes the fabric adhere to the skin and affects the wearing comfort of the clothes.

[0004] Therefore, a new scheme is needed to solve the problem of poor moisture absorption and moisture dissipation of polyester fabric. SUMMARY

[0005] In view of the deficiencies in the prior art, the purpose of the utility model is to provide a moisture absorption and perspiration polyester composite fabric, which improves the moisture absorption and moisture dissipation of polyester fabric through a new structure.

[0006] The above technical purpose of the utility model is realized by the following technical scheme: the moisture absorption and perspiration polyester composite fabric comprises an inner layer and an outer layer fixedly connected to each other, the outer layer is provided with a plurality of protrusions on the side away from the inner layer, the outer layer is provided with a plurality of recesses on the side close to the inner layer, the outer layer is provided with a plurality of air grooves one and a plurality of air grooves two, the air grooves one and the recesses are in communication with each other, the inner layer is provided with a plurality of moisture guide strips on the side close to the outer layer, adjacent moisture guide strips and the inner layer, the outer layer and the plurality of recesses form an air space, the inner layer is provided with a plurality of air holes in communication with the air space, and the moisture absorption of the outer layer is greater than that of the inner layer.

[0007] The utility model is further provided as follows: the plurality of protrusions and the plurality of recesses are formed by extruding and deforming the two sides of the outer layer through two embossing rollers, and the distance between adjacent protrusions along the length direction of the inner layer is twice the distance between adjacent air grooves one and air grooves two.

[0008] The utility model is further provided as follows: the air grooves one are located on the protrusions, the air grooves two are staggered along the length direction of the inner layer, and the plurality of air grooves one and the plurality of air grooves two are formed by cutting the outer layer.

[0009] The present invention is further configured such that: the inner layer is made by alternating weaving of moisture-absorbing yarn with perforated structure and raised strip structure; the plurality of air-permeable holes are all made by weaving perforated structure; and the plurality of moisture-wicking strips are all made by weaving raised strip structure.

[0010] The present invention is further configured such that: the moisture-absorbing yarn is made by spirally winding a first strand around a second strand, the first strand being made by twisting cotton fibers, and the second strand being made by twisting polyester shaped fibers with a Y-shaped cross section.

[0011] The present invention is further configured such that: the side of the moisture-wicking strip away from the inner layer abuts against two of the several breathable grooves opened in the outer layer; the width of the moisture-wicking strip is greater than the length of the second breathable groove; and the abutting part of the outer layer and the moisture-wicking strip is fixed by reciprocating stitching with moisture-wicking yarn.

[0012] The present invention is further configured such that: the outer layer is made by a plain weave of moisture-wicking yarn, the moisture-wicking yarn is made by spirally winding a third strand around a second strand, the third strand is made by twisting flax fibers, and the moisture absorption of the third strand is greater than that of the first strand.

[0013] In summary, this utility model has the following beneficial effects: The increased protrusions increase the contact area between the outer layer and the air, thereby improving the moisture-wicking performance of the outer layer. The interconnected ventilation channels, ventilation spaces, and ventilation holes improve airflow on both sides of the fabric, preventing stuffiness during wear. This improved airflow further enhances the overall moisture-wicking performance of the fabric. Simultaneously, the ventilation channels increase the three-dimensionality of the protrusions, enriching the visual appeal of the fabric. The ventilation channels also improve the moisture-wicking performance at the moisture-wicking strips, preventing the increased fabric thickness due to the moisture-wicking strips from affecting the moisture-wicking and breathability. Cotton fibers have good moisture absorption, allowing the inner layer to absorb sweat from the skin in a timely manner. Linen fibers have even better moisture absorption and wicking properties than cotton fibers, allowing moisture in the inner layer to be quickly transferred to the outer layer through the moisture-wicking strips and dissipated, thus maintaining the dryness of the fabric and skin, resulting in comfortable clothing.

[0020] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0021] Example: Moisture-wicking polyester composite fabric, such as Figures 1-4 As shown, the inner layer 1 and the outer layer 2 are fixedly connected to each other. The inner layer 1 is provided with a number of moisture-wicking strips 7 on the side near the outer layer 2. The length of the moisture-wicking strips 7 is the same as the width of the inner layer 1. The number of moisture-wicking strips 7 are symmetrically arranged on the inner layer 1 along the length direction of the outer layer 2. The inner layer 1 is provided with a number of vent holes 9. The number of vent holes 9 are arranged in an array between adjacent moisture-wicking strips 7 along the width direction of the inner layer 1. The inner layer 1 is made by feeding the moisture-absorbing yarn 10 into the air-jet loom and weaving it alternately with perforated structure and raised strip structure. The number of moisture-wicking strips 7 are all made by the weaving method of raised strip structure. The number of vent holes 9 are all made by the weaving method of perforated structure. The number of vent holes 9 improves the air permeability of the inner layer 1.

[0022] like Figure 1 and Figure 4 As shown, the moisture-absorbing yarn 10 is made by spirally winding a first strand 11 onto a second strand 12 using a fancy twisting machine. The first strand 11 is made by twisting cotton fibers using a twisting machine, and the second strand 12 is made by twisting polyester profiled fibers with a Y-shaped cross-section using a twisting machine. The polyester profiled fibers with a Y-shaped cross-section are spun through a spinneret. By shaping the polyester fibers, they gain larger gaps and surface areas, thereby improving the moisture absorption and breathability of the polyester fibers. Cotton fibers have good moisture absorption and breathability, allowing the inner layer 1 to absorb sweat produced by the skin in a timely manner and keep the skin dry. At the same time, cotton fibers have a soft and comfortable touch, further improving the wearing comfort of the fabric.

[0023] like Figures 1-3As shown, the outer layer 2 has several protrusions 3 arranged in an array on the side away from the inner layer 1, and several recesses 4 are formed on the side of the outer layer 2 closer to the inner layer 1. The cross-sectional shape of the protrusions 3 is the same as that of the recesses 4. The protrusions 3 and the recesses 4 are formed by extrusion and deformation on both sides of the outer layer 2 by two embossing rollers. The protrusions 3 increase the contact area between the outer layer 2 and the air, thereby improving the moisture dissipation performance of the outer layer 2. Various shapes of protrusions 3 can be formed on the outer layer 2 according to customer needs, thereby enriching the visual appearance of the outer layer 2. For aesthetic purposes, the outer layer 2 has several ventilation grooves 5 and 6 that are cut through it. The ventilation grooves 5 and 6 have the same cross-sectional shape. The ventilation grooves 5 and 6 improve the breathability of the outer layer 2. The ventilation grooves 5 and 6 are formed integrally through the outer layer 2 by a laser cutting machine. The ventilation groove 5 is located on the protrusion 3, so that the ventilation groove 5 and the recess 4 are interconnected. The ventilation groove 5 increases the three-dimensionality of the protrusion 3 and further enriches the visual aesthetics of the outer layer 2.

[0024] like Figures 1-3 As shown, the distance between adjacent protrusions 3 along the length of the inner layer 1 is twice the distance between adjacent ventilation grooves 5 and 6. Ventilation grooves 6 and protrusions 3 are staggered along the length of the inner layer 1. The side of the moisture-wicking strip 7 away from the inner layer 1 abuts against several ventilation grooves 6 on the outer layer 2. The width of the moisture-wicking strip 7 is greater than the length of the ventilation grooves 6. The abutting part of the outer layer 2 and the moisture-wicking strip 7 is fixed by repeated stitching with moisture-wicking yarn 13, so that ventilation space 8 is formed between adjacent moisture-wicking strips 7 and the inner layer 1, outer layer 2 and several recesses 4. Several ventilation holes 9 located between adjacent moisture-wicking strips 7 are all interconnected with the ventilation space 8. The interconnected ventilation grooves 5, ventilation space 8 and ventilation holes 9 improve the air circulation effect on both sides of the fabric, avoid the fabric from feeling stuffy when worn, and further enhance the overall moisture-wicking performance of the fabric through good air circulation.

[0025] like Figures 1-5 As shown, the outer layer 2 is made by feeding the moisture-wicking yarn 13 into an air-jet loom and weaving it with a plain weave. The moisture-wicking yarn 13 is made by spirally winding a third strand 14 onto a second strand 12 using a fancy twisting machine. The third strand 14 is made by twisting flax fibers using a twisting machine. Flax fibers have strong moisture-wicking properties due to their special porous structure, which allows the outer layer 2 to quickly remove moisture from its interior. Flax fibers have stronger moisture absorption and wicking properties than cotton fibers, making the moisture absorption of the outer layer 2 greater than that of the inner layer 1. Therefore, the moisture absorbed in the inner layer 1 can be transferred to the outer layer 2 through several moisture-wicking strips 7 and quickly removed, thereby keeping the fabric and skin dry and making the finished garment comfortable to wear.

[0026] like Figures 1-5As shown, when it is necessary to make this moisture-wicking polyester composite fabric, firstly, the woven outer layer 2 is cut through by a laser cutting machine to create several ventilation grooves 5 and several ventilation grooves 6. Then, an embossing machine is used to process the ventilation grooves 5 on the outer layer 2 to form several protrusions 3 and several depressions 4. The woven inner layer 1 is laid flat with the integrally formed moisture-wicking strips 7 facing upwards. After moving the ventilation holes 6 on the outer layer 2 to directly above the moisture-wicking strips 7 on the inner layer, the outer layer 2 is placed on top of the inner layer 1. Finally, the inner layer 1 and the outer layer 2 are sewn together and fixed with a sewing machine to complete the production of the moisture-wicking polyester composite fabric.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
