Description

Technical Field

[0001] This utility model relates to the field of denim fabric technology, specifically to a breathable and durable denim fabric. Background Technology

[0002] Denim is a classic woven fabric, originally used for workwear and renowned for its durability and abrasion resistance. Its unique indigo dyeing process gives the fabric varying shades of blue, making it both vintage and versatile. The fabric has a clear texture, and with different finishing processes, it can be given diverse styles such as distressed, ripped, and washed finishes, making it widely used in various garments, especially jeans.

[0003] Traditional denim fabric is loved by consumers for its unique style, but it generally suffers from poor breathability, making it uncomfortable to wear in summer. While there are breathable knitted denim fabrics on the market, their durability is insufficient. As people's living standards improve, the performance requirements for denim fabrics are also increasing. They not only demand that it maintain its traditional look and texture but also desire better breathability and durability to meet the needs of daily wear and various activities. Therefore, we propose a breathable and durable denim fabric. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a breathable and durable denim fabric that can maintain the traditional appearance and texture while having better breathability and durability to meet the needs of daily wear and various activities.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A breathable and durable denim fabric includes a fabric woven from warp and weft yarns using a honeycomb weave, the surface of which is coated with a hydrophilic layer.

[0006] Preferably, both the warp and weft yarns are made of irregular cross-section fiber materials.

[0007] Preferably, the honeycomb weave is a composite weave, specifically including 5 / 1 weave units, 2 / 2 weave units and 1 / 1 weave units arranged in a sequential cycle.

[0008] Preferably, in the 5 / 1 weave unit, every 5 warp yarns float above the corresponding weft yarns in sequence, and then 1 warp yarn sinks below the corresponding weft yarn; in the 2 / 2 weave unit, every 2 warp yarns float above the corresponding weft yarns in sequence, and then both warp yarns sink below the corresponding weft yarn; in the 1 / 1 weave unit, one warp yarn floats above the weft yarn, and the next adjacent warp yarn sinks below the weft yarn.

[0009] Preferably, the hydrophilic layer is made of polyvinyl alcohol (PVA).

[0010] Preferably, the thickness of the hydrophilic layer is 0.05-0.1 mm.

[0011] Beneficial effects This invention provides a breathable and durable denim fabric. Compared with the prior art, it has the following advantages: This breathable and durable denim fabric is woven with warp and weft yarns using a honeycomb weave. Both warp and weft yarns utilize irregularly shaped cross-section fibers. The unique structure of these fibers gives both warp and weft yarns quick-drying and breathable properties, thus improving the fabric's quick-drying and breathability. The honeycomb weave, with its multiple weaving units, not only gives the fabric a unique visual appeal but also creates more and more complex air channels and gaps within the fabric, significantly enhancing its breathability. The fabric surface is coated with a hydrophilic layer made of polyvinyl alcohol (PVA). PVA enhances the fabric's durability while maintaining its breathability, allowing it to retain its traditional appearance and texture while providing superior breathability and durability to meet the needs of everyday wear and various activities.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a breathable and durable denim fabric, including fabric 1, which is woven from warp yarns 3 and weft yarns 4 using a honeycomb weave, and the surface of fabric 1 is coated with a hydrophilic layer 2.

[0016] Both warp yarn 3 and weft yarn 4 use irregular cross-section fiber materials.

[0017] By using irregularly shaped cross-section fibers to spin warp yarns 3 and weft yarns 4, the irregularly shaped cross-section fibers break the structure of traditional circular fibers. Their unique geometry increases the specific surface area of ​​the fibers, allowing for more sufficient contact between the fibers and the air. During the evaporation of moisture, it is as if providing more "escape channels" for the moisture, accelerating the diffusion of moisture into the air, thereby achieving quick drying. Due to the irregular shape of the fibers themselves, more and more complex gaps and channels are formed inside and between the yarns. These gaps and channels are interconnected, forming an air circulation network. When the heat and moisture generated by the human body try to escape, they can quickly escape along these channels, while fresh air from the outside can also enter smoothly, achieving efficient air exchange and breathability. This gives both warp yarns 3 and weft yarns 4 quick-drying and breathable functions, thereby improving the quick-drying and breathable performance of fabric 1.

[0018] Honeycomb weaving is a composite weaving method, specifically consisting of 5 / 1 weaving units, 2 / 2 weaving units, and 1 / 1 weaving units arranged in a sequential cycle.

[0019] In a 5 / 1 weave unit, every 5 warp yarns 3 float above the corresponding weft yarns 4, and then one warp yarn 3 sinks below the corresponding weft yarn 4; in a 2 / 2 weave unit, every 2 warp yarns 3 float above the corresponding weft yarns 4, and then both warp yarns 3 sink below the corresponding weft yarns 4; in a 1 / 1 weave unit, one warp yarn 3 floats above the weft yarn 4, and the next adjacent warp yarn 3 sinks below the weft yarn 4.

[0020] The honeycomb weave, which combines 5 / 1, 2 / 2, and 1 / 1 weave units, not only creates a unique texture or three-dimensional effect on the surface of fabric 1, giving it a unique visual appeal, but also creates more and more complex air channels and gaps within fabric 1. Compared to a single weave, this composite weave makes the structure of fabric 1 more porous, allowing air to flow more easily between the warp yarns 3 and weft yarns 4, thereby greatly improving the breathability of fabric 1.

[0021] The hydrophilic layer 2 is made of polyvinyl alcohol (PVA) material, and the thickness of the hydrophilic layer 2 is 0.05-0.1 mm.

[0022] The organosilicon molecules of polyvinyl alcohol (PVA) material can be oriented on the fiber surface with their hydrophilic groups facing outward, making the surface of fabric 1 hydrophilic without affecting the gaps between fibers, thus ensuring the breathability of fabric 1. Through finishing processes such as post-baking, polyvinyl alcohol (PVA) can undergo chemical reactions or cross-linking and curing with the fibers, thereby improving the durability of fabric 1.

[0023] Working principle: Fabric 1 is woven from warp yarns 3 and weft yarns 4 using a honeycomb weave. Both warp yarns 3 and weft yarns 4 use irregularly shaped cross-section fiber materials. This irregular cross-section fiber breaks the traditional circular fiber structure, and its unique geometry increases the fiber's specific surface area. This increased surface area allows for more thorough contact between the fiber and the air. During moisture evaporation, it acts like providing more "escape channels" for the moisture, accelerating its diffusion into the air and achieving quick drying. Due to the irregular shape of the fiber itself, more and more complex gaps and channels are formed inside and between the yarns. These gaps and channels are interconnected, forming an air circulation network. When the heat and moisture generated by the human body attempt to escape, they can travel along... These channels allow for rapid airflow while simultaneously enabling the smooth entry of fresh air from the outside, achieving efficient air exchange and breathability. This allows both warp yarns 3 and weft yarns 4 to possess quick-drying and breathable functions, thereby improving the quick-drying and breathability performance of fabric 1. The honeycomb weave, which combines 5 / 1 weave units, 2 / 2 weave units, and 1 / 1 weave units, not only creates unique textures or three-dimensional effects on the surface of fabric 1, giving it a unique visual appeal, but also forms more and more complex air channels and gaps within fabric 1. Compared to a single weave, this composite weave makes the structure of fabric 1 more porous, allowing air to flow more easily between the warp yarns 3 and weft yarns 4, thus greatly improving the breathability of fabric 1. Fabric 1 is coated with a hydrophilic layer 2, which is made of polyvinyl alcohol (PVA). The organosilicon molecules of PVA can be oriented on the fiber surface with their hydrophilic groups facing outward, making the surface of fabric 1 hydrophilic without affecting the gaps between fibers, thus ensuring the breathability of fabric 1. Through finishing processes such as baking, PVA can chemically react with the fibers or cross-link and cure, improving the durability of fabric 1.
