Description

Technical Field

[0001] The invention relates to the technical field of denim fabric weaving, and in particular to a soft and cool denim fabric and a weaving method thereof. Background Art

[0002] As a classic and widely used fabric, denim fabric occupies an important position in people's daily life. However, traditional denim fabric has certain limitations in performance. In hot seasons or specific environments, traditional denim fabrics often show problems such as insufficient softness, poor moisture absorption and air permeability, and lack of coolness due to their material and structure. The warp and weft yarns of traditional denim fabrics usually use single fibers or simple fiber combinations, which cannot give full play to the advantages of different fibers, resulting in the fabrics being difficult to meet people's growing needs in terms of skin-friendliness, comfort, and heat dissipation performance. For example, although common pure cotton denim fabrics are soft and comfortable, they have limited moisture absorption and air permeability, and are easy to stick to the skin when sweating, causing discomfort; while some denim fabrics containing chemical fibers may have certain strength and durability, but they are often not soft enough and lack coolness. With the improvement of people's living standards and the pursuit of wearing comfort, these shortcomings of traditional denim fabrics have become more and more obvious, and an innovative denim fabric with better performance is urgently needed to improve this situation.

[0003] It can be seen that the existing technology still needs to be improved and enhanced. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a soft and cool denim fabric and a weaving method thereof, so as to solve the problems of insufficient softness, poor moisture absorption and poor air permeability of the denim fabric in the prior art.

The warp yarn is divided into N original warp beams by a ball warp machine, and each original warp beam is dyed by a rope dyeing machine to obtain N dyed warp yarn bundles; the dyed warp yarn bundles are evenly divided into N dyed warp beams by a warp dividing machine, and the N dyed warp beams are combined and sized by a sizing machine and then wound into a weaving beam; S4. The warp yarn of the weaving beam is passed through the machine according to the organization and woven with the weft yarn through a rapier loom to form a grey cloth, which is then post-processed to obtain a denim fabric.

[0006] In one embodiment of the present invention, the warp yarn has a count of 6-32S, and the weft yarn has a count of 6-32S.

[0007] In one embodiment of the present invention, the weft density of the grey fabric is 38-53 threads / inch and the weight is 5-13 ounces / square yard.

[0008] The beneficial effects of the above-mentioned embodiments are that the grey cloth has a tight structure and stable connection, which helps to improve the tear strength and wear resistance of the grey cloth, making the manufactured product more durable.

[0009] In one embodiment of the present invention, in step S4, the warp yarns and the weft yarns are interwoven by weaving on a rapier loom using a straight-through weaving process.

[0012] As described above, the soft and cool denim fabric and its weaving method of the present invention have the following beneficial effects: the rush in the weft yarn is rich in natural ingredients of nitrogen and silicon with high thermal conductivity, which can achieve the effect of rapid heat dissipation on the surface. At the same time, the rush contains highly volatile and highly hygroscopic alcohol and ester components, which can achieve a cool feeling by rapid moisture conduction. Its unique structure can quickly dissipate heat and can quickly absorb sweat to keep the skin dry and comfortable. In addition, the rush also has antibacterial and fresh aromatic properties, which can inhibit bacterial growth and reduce odor generation. The unique weft yarn combination in the denim fabric enables the denim fabric to achieve a comprehensive improvement in performance while maintaining the inherent characteristics of the denim fabric.

The warp yarn of the weaving beam is passed through the machine according to the organization and the weft yarn is woven with the rapier loom to form a grey cloth, which is then post-processed to obtain a denim fabric.

[0018] See also Figure 6 , Rush Herb Cool Nylon Modified Fiber comes from cultivated rush, which is bred from wild rush through long-term artificial selection. The grass stems are smooth and slender, uniform in thickness, straight and green in color, with sparse wall core, rich fragrance, long fibers, elasticity, and good tensile strength. It is an excellent natural green fiber. Rush has a hollow structure and has good moisture absorption and perspiration function. It also contains a variety of phenolic small molecules, has a fresh and fragrant smell, and has antibacterial effects. The cooling performance is a highlight of this fabric. Rush Herb Cool Nylon Fiber has the characteristics of rapid heat dissipation and moisture conduction, which gives the fabric a significant cooling effect. In a high temperature environment, the wearer can obviously feel cool and comfortable, which greatly improves the wearing experience in hot seasons or special environments.

[0019] Optionally, the warp yarn has a count of 6-32S, and the weft yarn has a count of 6-32S.

The 3 / 1 right twill weave structure enhances the strength and wear resistance of the denim fabric in the warp and weft directions, so that the denim fabric can withstand greater tension and friction, and is not easy to be damaged or worn, thereby extending the service life of the clothing. The straight-through method can ensure the consistency of the interweaving pattern of the warp and weft yarns, making the fabric surface smoother and more uniform, which helps to improve the appearance quality of the fabric and meet the market demand for high-quality fabrics.

The moisture absorption characteristics of cotton fiber and lyocell fiber in the warp yarn, combined with the good moisture conduction function of linbencao icy nylon in the weft yarn, can quickly absorb and discharge sweat produced by the human body. Even in a hot and humid environment, it can keep the skin dry and effectively avoid the discomfort caused by sweat accumulation.

[0022] In addition, denim fabrics have excellent durability and wrinkle resistance. The high strength of the lyocell fiber in the warp yarn and the special finishing process enable the fabric to maintain good shape and performance after long-term use and multiple washings, and it is not easy to be damaged and wrinkled, extending the service life of the clothing.
