TECHNICAL FIELD

[0001] The utility model relates to textile technology field more specifically, it relates to a quick dry terylene fabric. BACKGROUND

[0002] Terylene fabric is a chemical fiber fabric woven by terylene fiber, and terylene fiber has good elasticity and wear resistance due to its compact molecular structure, so that the made fabric is not easy to wear and deform, therefore terylene fabric is widely used in the manufacture of clothing, household supplies, backpacks and other products.

[0003] However, the compact molecular structure of terylene fiber reduces the pore and surface area in the fiber, which is not conducive to the circulation of gas and the penetration and diffusion of moisture, so that the air permeability and moisture permeability of terylene fabric are relatively poor, and it is easy to produce stuffy feeling when wearing, easy to sweat and the continuously produced sweat cannot be quickly removed through the fabric and retained on the skin surface, which affects the wearing comfort.

[0004] Therefore, a new scheme needs to be proposed to solve this problem. UTILITY MODEL CONTENT

[0005] In view of the deficiencies in the prior art, the utility model aims at providing a quick dry terylene fabric, which improves the air permeability and moisture permeability of terylene fabric through new structure setting.

[0006] The above technical purpose of the utility model is realized by the following technical scheme: a quick dry terylene fabric, comprising an inner layer and an outer layer, the inner layer comprises a plurality of air permeable parts and a plurality of moisture conducting parts arranged alternately along the length direction thereof, the two sides of the air permeable part are respectively provided with a recess and a protrusion, the two sides of the outer layer are respectively provided with a plurality of grooves and a plurality of protrusions, the gap between the plurality of protrusions and the outer layer and the recess forms an air permeable space, the air permeable part array is provided with a plurality of air permeable holes which are in communication with the air permeable space, the protrusion is provided with an air permeable groove which is in communication with the groove and the air permeable space, and the moisture absorption of the outer layer is greater than that of the moisture conducting part.

[0007] The utility model is further provided as follows: the curvature of the recess is the same as that of the protrusion, and the recess and the protrusion are both formed by hot pressing and setting of the air permeable part.

[0008] The utility model is further provided as follows: the side length of the protrusion is greater than that of the groove, the groove is located directly above the protrusion, and the protrusion and the groove are both formed by hot pressing and setting of the outer layer, and the air permeable groove is connected to the bottom surface of the groove.

[0009] The utility model is further provided as follows: the depth of the recess is greater than the thickness of the protrusion, and the width of the recess is greater than the side length of the protrusion.

[0010] The present invention is further configured such that: the two sides of the length of the moisture-wicking part are sewn to the outer layer by abrasion-resistant yarn, and the inner layer is made by abrasion-resistant yarn through a perforated structure and plain weave alternatingly.

[0011] The present invention is further configured such that: the wear-resistant yarn is formed by twisting multiple strands of first strand, and the first strand is formed by twisting polyester shaped fibers with a five-lobed cross section.

[0021] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] Example: A quick-drying polyester fabric, such as Figure 1 , Figure 4 and Figure 5 As shown, the inner layer 1 and the outer layer 2 are fixedly connected to each other. The inner layer 1 includes a number of breathable parts 3 and a number of moisture-wicking parts 4 arranged alternately along its length. The breathable parts 3 are arrayed with a number of breathable holes 10, which improves the breathability of the inner layer 1. The warp and weft yarns of the inner layer 1 are both made of abrasion-resistant yarns 12. The inner layer 1 is made by feeding the abrasion-resistant yarns 12 into an air-jet loom and weaving them alternately with perforated and plain weave structures. The moisture-wicking parts 4 are woven integrally with the plain weave structure on the inner layer 1. The breathable parts 3 and the number of breathable holes 10 are woven integrally with the perforated weave structure on the inner layer 1.

[0023] like Figures 1-5 As shown, the wear-resistant yarn 12 is formed by twisting two strands of the first strand 13 together using a twisting machine. The first strand 13 is formed by twisting polyester profiled fibers with a five-lobed cross-section using a twisting machine. The polyester profiled fibers with a five-lobed cross-section are then spun through a spinneret. By shaping the polyester fibers, the internal pores and surface area of ​​the fibers are increased, thereby improving the moisture absorption and breathability of the polyester fibers. This results in the inner layer 1 having a certain degree of breathability and moisture absorption, reducing the feeling of stuffiness, and effectively absorbing sweat produced by the skin. The breathable part 3 has a recess 5 on the side near the outer layer 2 and a protrusion 6 on the side away from the outer layer 2. The concave 5 has the same curvature as the convex 6. Both the concave 5 and the convex 6 are formed by hot pressing the breathable part 3 on the inner layer 1 through a hot press. The bottom plate of the hot press has a forming groove with the same curvature as the convex 6. The pressure plate of the hot press is integrally formed with a pressure block with the same curvature as the concave 5. The inner layer 1 can be hot-pressed and shaped by the cooperation of the pressure plate and the bottom plate. The convex 6 reduces the contact area between the inner layer 1 and the skin, thereby increasing the air circulation between the inner layer 1 and the skin. The polyester profiled fiber has high elasticity and wear resistance, making the inner layer 1 less prone to wear and deformation, thus improving its service life.

[0024] like Figure 1 , Figure 3 and Figure 4As shown, the outer layer 2 has several square-section protrusions 8 arranged on the side near the inner layer 1, and several square-section grooves 7 arranged on the side away from the inner layer 1. The side length of the protrusions 8 is greater than the side length of the grooves 7. The grooves 7 are located directly above the protrusions 8. A ventilation groove 11 that communicates with the grooves 7 is opened through the protrusions 8. The contact area between the outer layer 2 and the air is increased by the several grooves 7, protrusions 8, and ventilation grooves 11, thereby improving the moisture dissipation speed of the outer layer 2. At the same time, the several ventilation grooves 11 improve the air permeability of the outer layer 2. The protrusions 8 and grooves 7 are both formed by hot pressing the outer layer 2 by a hot press. The bottom plate of the hot press has a forming groove with the same cross-sectional shape as the protrusions 8. The pressure plate of the hot press is integrally formed with a pressure block with the same cross-sectional shape as the grooves 7. The outer layer 2 can be hot-pressed and shaped by the cooperation of the pressure block and the bottom plate.

[0025] like Figure 1 , Figure 3 and Figure 4 As shown, the length of the moisture-wicking part 4 is fixed to the outer layer 2 by sewing with abrasion-resistant yarn 12 using a sewing machine, which ensures the fixing effect of the inner layer 1 and the outer layer 2. This makes the gaps between the protrusions 8 and the outer layer 2 and the recesses 5 form several breathable spaces 9. The depth of the recesses 5 is greater than the thickness of the protrusions 8, and the width of the recesses 5 is greater than the side length of the protrusions 8. This makes the breathable grooves 11 on the protrusions 8 interconnected with the breathable spaces 9. The breathable holes 10 on the breathable part 3 are also interconnected with the breathable spaces 9. The interconnected breathable spaces 9, breathable holes 10, and breathable grooves 11 improve the air circulation effect on both sides of the fabric, thereby enhancing the breathability and moisture dissipation speed of the fabric, making it less likely to feel stuffy when wearing it.

[0026] like Figure 1 and Figure 6 As shown, both the warp and weft yarns of the outer layer 2 are set as moisture-wicking yarns 14. The outer layer 2 is made by feeding the moisture-wicking yarn 14 into an air-jet loom and weaving it with a plain weave. The moisture-wicking yarn 14 is made by spirally winding a second strand 15 onto a first strand 13 using a ring spinning machine. The second strand 15 is made by twisting flax fibers using a twisting machine. Due to its special porous structure, flax fibers can quickly absorb and wick away moisture, making the moisture absorption of the second strand 15 greater than that of the first strand 13. Therefore, the moisture absorption of the outer layer 2 is greater than that of the inner layer 1, allowing the outer layer 2 to absorb moisture from the inner layer 1 in a timely manner and quickly wick it away through several moisture-wicking parts 4, thereby keeping the inner layer 1 and the skin dry and improving wearing comfort.

[0027] like Figures 1-6As shown, when it is necessary to make this kind of quick-drying polyester fabric, firstly, a hot press is used to heat-press and shape several grooves 7 and several protrusions 8 on both sides of the woven outer layer 2 through the cooperation of the second base plate and the second pressure plate. Then, a laser cutting machine is used to cut ventilation grooves 11 in the middle of the several protrusions 8 on the outer layer 2. The hot press is used to heat-press and shape depressions 5 and protrusions 6 on both sides of the woven inner layer 1 through the cooperation of the first base plate and the first pressure plate. The outer layer 2 is laid flat with the side with the protrusions 8 facing up. The inner layer 1 is then placed on the outer layer 2 with the side with the depressions 5 facing down. By moving the outer layer 2 horizontally, the several depressions 5 are moved to the top of the several protrusions 8. Finally, the inner layer 1 and the outer layer 2 are sewn together and fixed by a sewing machine, thereby completing the production of this kind of quick-drying polyester fabric.

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.
