Description

Technical Field

[0001] This utility model relates to the field of textile technology, and more specifically, to a chemical fiber fabric. Background Technology

[0002] Chemical fiber fabric is a common type of yarn fabric, usually woven from chemical fibers such as polyester, nylon, spandex, and acrylic. Due to their good elasticity and abrasion resistance, chemical fiber fabrics are not easy to wrinkle or break, and are widely used in clothing, bags, home textiles, and outdoor products.

[0003] However, the aforementioned chemical fibers generally suffer from insufficient breathability and moisture wicking. Due to the tight molecular structure of the fibers, air circulation is poor, and when the human body sweats, the sweat is difficult to evaporate quickly, resulting in a stuffy, sticky, and uncomfortable feeling.

[0004] Therefore, a new solution is needed to address this problem. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a chemical fiber fabric.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a chemical fiber fabric, including an inner layer and an outer layer, wherein the inner layer has a plurality of protrusions one and a plurality of protrusions two on both sides, and the inner layer and the outer layer are supported by the plurality of protrusions one to form a plurality of ventilation cavities, and the outer layer includes a plurality of moisture-wicking parts and a plurality of breathable parts arranged alternately along its warp direction, wherein the breathable parts array has a plurality of breathable holes one, and the moisture-wicking parts and the protrusions two each have a plurality of breathable holes two, and the breathable holes one and the breathable holes two are all interconnected with the ventilation cavities.

[0007] The present invention is further configured such that a plurality of protrusions one and a plurality of protrusions two are staggered along the weft direction of the inner layer, and both protrusions one and two are formed by hot pressing of the inner layer.

[0008] The present invention is further configured such that: the weaving structure of the inner and outer layers is a plain weave, and the warp and weft threads of the inner and outer layers are both moisture-wicking yarns, wherein the moisture-wicking yarns are made by spirally winding the first strand around the second strand.

[0009] The present invention is further configured such that: the first strand is made of viscose fiber twisted together, the second strand is made of polyester profiled fiber twisted together, and the diameter of the first strand is larger than the diameter of the second strand.

[0010] The present invention is further configured such that: a plurality of the ventilation holes are formed by removing the first strand of yarn through a deburring process of the ventilation part and increasing the spacing between the warp and weft yarns; and the thickness of the two sides of the ventilation part is reduced after the first strand of yarn is removed, thus forming grooves.

[0011] The present invention is further configured such that: a plurality of the second ventilation holes are arranged in an array along the warp direction of the inner layer, and the second ventilation holes on the moisture dissipation part and the second ventilation holes on the second protrusion are the same size and are arranged opposite to each other.

[0012] In summary, this utility model has the following beneficial effects: several interconnected ventilation chambers, ventilation holes one and two improve the air circulation effect inside and on both sides of the fabric; the support of several protrusions two improves the air circulation effect between the inner layer and the skin, thereby obtaining good breathability. At the same time, the good air circulation effect enhances the moisture evaporation speed of the fabric. Since the moisture absorption of viscose fiber is greater than that of polyester profiled fiber, the moisture absorbed by the fabric will be dispersed on the viscose fiber as the outer yarn, so that the good air circulation can directly contact the viscose fiber for rapid moisture evaporation, making the finished fabric breathable and quick-drying comfortable to wear.

[0018] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0019] Example: A synthetic fiber fabric, such as Figures 1-3As shown, it includes an inner layer 1 and an outer layer 2. The inner layer 1 has several protrusions 101 and several protrusions 102 on both sides. The protrusions 101 and 102 have the same cross-sectional shape. The protrusions 101 and 102 are staggered along the weft direction of the inner layer 1. The protrusions 101 and 102 are formed by hot pressing the inner layer 1 using a hot press. The hot press has two plates with pressure blocks 1 and 2. Pressure block 1 is opposite to protrusion 101, and pressure block 2 is opposite to protrusion 102. After the two pressure plates hot press the inner layer 1, protrusions 101 and 102 are formed. The support of the protrusions 102 increases the gap between the inner layer 1 and the skin, thereby improving the air circulation between the inner layer 1 and the skin, making the inner layer 1 less likely to stick to the skin.

[0020] like Figures 1-4 As shown, the inner layer 1 and outer layer 2 are stitched together at several protrusions 101, forming several ventilation cavities 3 under the support of the protrusions 101. The outer layer 2 includes several moisture-wicking sections 201 and several breathable sections 202 arranged alternately along its warp direction. The breathable sections 202 are arrayed with several breathable holes 4. Several breathable holes 5 are simultaneously drilled through the moisture-wicking sections 201 and the protrusions 102 by a laser punch. The weave of both the inner layer 1 and the outer layer 2 is a plain weave. Due to the interlacing of the warp and weft threads, it is not easy to loosen after cutting. At the same time, the high temperature generated during laser cutting can seal the cut edges. The edge treatment ensures the structural stability of the inner layer 1 and outer layer 2 after cutting out several ventilation holes 25. The ventilation holes 25 on the moisture-wicking part 201 and the ventilation holes 25 on the protrusion 202 are the same size and are arranged opposite each other. Several ventilation holes 25 are arranged in an array along the warp direction of the inner layer 1, so that several ventilation holes 14 and several ventilation holes 25 are interconnected with the ventilation cavity 3. Several interconnected ventilation cavities 3, ventilation holes 14 and ventilation holes 25 improve the air circulation effect inside and on both sides of the fabric, thereby obtaining good breathability. At the same time, the good air circulation effect enhances the moisture wicking speed of the fabric, further reducing the situation where the inner layer 1 sticks to the skin.

[0021] like Figure 2As shown, both inner layer 1 and outer layer 2 are woven using an air-jet loom. The warp and weft yarns of inner layer 1 and outer layer 2 are set as moisture-wicking yarns. The moisture-wicking yarn is made by spirally winding a first strand of yarn onto a second strand of yarn using a ring spinning machine. The first strand of yarn is made by twisting viscose fiber using a twisting machine, and the second strand of yarn is made by twisting polyester profiled fiber using a twisting machine. By shaping the polyester fiber, the gaps and surface area within the fiber are increased, which is conducive to air circulation and moisture penetration and diffusion, thereby improving the breathability and moisture-wicking properties of the polyester fiber. The polyester profiled fiber has high strength and elasticity, so the moisture-wicking yarn made of polyester profiled fiber as the yarn core has good elasticity and is not easy to tear or break, thus ensuring the weaving strength of the fabric.

[0022] like Figure 1 As shown, the production process of viscose fiber involves rearranging the cellulose structure, resulting in a looser molecular structure with more gaps and pores. This allows water molecules to absorb and diffuse more easily. Furthermore, viscose fiber molecules contain a large number of hydrophilic groups, giving them superior hygroscopicity and rapid moisture dissipation compared to polyester profiled fibers. This means that moisture absorbed by the moisture-dissipating yarn is dispersed within the viscose fiber, which acts as the outer yarn. Moisture does not easily remain in the yarn core for extended periods. Therefore, good air circulation allows for direct contact with the viscose fiber, enabling rapid moisture dissipation. Apparel made from this fabric offers a breathable and quick-drying comfortable feel. The breathable section 202 undergoes a burnout process, where burnout paste is applied to the breathable section 202 using a transfer printing machine. This burnout paste is an acidic solution. Viscose fibers have poor alkali resistance, while polyester fibers have good acid resistance. The printed outer layer 2 undergoes heat treatment, causing the cellulose molecular chains of the viscose fibers to break upon contact with the acidic solution, thus being removed by the acidic burnout paste. After the burnout process, the outer layer 2 is washed with water to remove impurities and excess printing paste.

[0023] like Figure 4 As shown, the diameter of the first strand is larger than that of the second strand. Therefore, after removing the first strand, which serves as the outer covering yarn, the diameter of the moisture-wicking yarn will shrink to less than one-third of its original size. Several ventilation holes 4 are formed by increasing the spacing between the warp and weft threads after removing the first strand through a burnout process on the ventilation section 202. The thickness of the ventilation section 202 is reduced due to the reduced diameter of the moisture-wicking yarn after the burnout process. Reducing the thickness of the ventilation section 202 facilitates the flow of air and further improves the breathability of the ventilation section 202. The reduced thickness of the ventilation section 202 forms a groove 6 on both sides. Several ventilation chambers 3 can be connected together through several grooves 6, further improving the air circulation effect inside the fabric and increasing the moisture wicking speed inside the 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.
