Description

Technical Field

[0001] This utility model relates to a fabric, specifically a super-imitation cotton polyester fiber fabric. Background Technology

[0002] Cotton fiber possesses natural moisture absorption, breathability, soft touch, and good biocompatibility, making it a mainstream raw material for traditional textile fabrics and widely used in clothing, home textiles, and other fields. However, cotton fiber production is limited by factors such as planting area and climate, resulting in significant price fluctuations. Furthermore, it has drawbacks such as being prone to wrinkling, having poor abrasion resistance, and weak corrosion resistance, making it difficult to meet the demands of high-end functional fabrics.

[0003] While ordinary polyester fabrics are durable and easy to care for, their poor moisture absorption makes them unsuitable for meeting consumers' demands for comfort and texture. With advancements in chemical fiber spinning technology, new fibers such as ultra-fine denier, multi-component composites, and raw material blends are emerging in large numbers. Furthermore, the application of nanotechnology has led to the continuous development of functional filaments. Among these, cotton-like polyester fiber filaments are favored for their short processing flow, low energy consumption, ease of assembly, and diverse properties. Therefore, this application provides a super-cotton-like polyester fiber fabric. Utility Model Content

[0004] The purpose of this invention is to provide a super-imitation cotton polyester fiber fabric, which aims to provide a texture close to that of cotton fiber fabric, while solving the problems of easy wrinkling of pure cotton fabric and poor moisture absorption of ordinary polyester fabric.

Detailed Implementation

[0014] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0015] Combination Figure 1-2 This embodiment provides a detailed description of a super-imitation cotton polyester fiber fabric, comprising: a fabric body, wherein the fabric body is a double-layered bonded structure, the double-layered bonded structure comprising a surface layer and an inner layer, both the surface layer and the inner layer being plain weaves; the surface layer is woven from surface warp yarns and surface weft yarns, and the inner layer is woven from inner warp yarns and inner weft yarns; the surface warp yarns and surface weft yarns are super-imitation cotton polyester fiber filaments; the inner warp yarns are antibacterial yarns; and the inner weft yarns are polyamide ester fiber yarns.

[0016] Furthermore, the outer layer warp yarns and inner layer warp yarns are arranged in a 1:2 ratio, and the outer layer weft yarns and inner layer weft yarns are arranged in a 1:2 ratio. The double-layered weft structure consists of an outer layer and an inner layer, each layer being woven from its own independent warp and weft yarns. These two independent layers are then connected using an appropriate weft-jointing method. Specifically, in this embodiment, the outer layer and inner layer are connected using a bottom-to-top weft-jointing method. Because the outer and inner layers are relatively independent, different raw materials can be used, simultaneously giving the fabric multiple functions and achieving a good cotton-like effect.

[0017] Furthermore, the cross-sectional shape of the super-imitation cotton polyester fiber filament is triangular.

[0018] Super-imitation cotton polyester filament achieves a soft, fluffy feel similar to cotton by controlling the fiber's cross-section, molecular chain segments, and fiber modulus. During the PTA and EG polymerization process, flexible segments are introduced into the PET fiber molecular chain segments, reducing their rigidity and improving the feel. In the spinning stage, the spinneret shape is changed, and a triangular cross-section spinneret is used to create shaped fibers, making the feel close to cotton. The triangular cross-section also creates grooves on the fiber surface, facilitating moisture absorption and wicking, and accelerating moisture absorption. By using an air network variation method, the filaments are blown into an intertwined, uneven state, presenting a curly, fluffy, and slightly curved three-dimensional appearance. Super-imitation cotton polyester fiber enables fabrics to possess the fluffiness, softness, and moisture absorption of cotton, while also having higher strength, wrinkle resistance, and quick-drying properties than cotton.

[0019] Furthermore, the antibacterial yarn is nano-zinc oxide modified nylon 6 filament. Nano-zinc oxide modified nylon 6 filament is produced using the masterbatch method in blend spinning. The inorganic antibacterial agent nano-zinc oxide is added to nylon 6 chips, and an antibacterial masterbatch is prepared using a screw extruder. Then, the antibacterial masterbatch and nylon 6 chips are thoroughly mixed and fed into a hopper for melt spinning. Zinc oxide is a white inorganic antibacterial agent that releases antibacterial ions upon use, thereby giving the product antibacterial properties. Nano-zinc oxide is an inorganic nano-antibacterial agent; due to its nano-carrier structure, its specific surface area is increased, allowing for better adsorption of microorganisms, thus achieving a superior antibacterial effect compared to micron-sized nano-zinc oxide. Specifically, with a zinc oxide mass fraction of 5% and an antibacterial masterbatch addition of 5%, the resulting nano-zinc oxide modified nylon 6 filament exhibits an antibacterial rate of over 90% against Candida albicans, Escherichia coli, and Staphylococcus aureus. Furthermore, the addition of nano-zinc oxide has minimal impact on the mechanical properties of the nano-zinc oxide modified nylon 6 filament.

[0020] Furthermore, the polyamide ester fiber yarn has an H-shaped cross-section. By introducing polyamide segments into the polyester macromolecular chain, the polyamide ester fiber combines the excellent properties of both natural and traditional synthetic fibers, compensating for the shortcomings of cotton fiber in terms of moisture wicking, wrinkle resistance, and insect resistance.

[0021] The breaking strength of polyamide ester fiber is between 2.5 cN / dtex and 3.0 cN / dtex, close to that of cotton fiber but lower than that of polyester. Due to the introduction of polyamide segments into the fiber macromolecular chain, the regular long-chain structure of the molecules is disrupted to some extent, reducing the rigidity of the macromolecules and increasing their flexibility, resulting in a lower fiber modulus. The initial modulus of polyamide ester fiber is less than 50 cN / dtex, about half that of ordinary polyester, and its breaking elongation is 20-40%. The strength of polyamide ester fiber yarn is between that of long-staple cotton yarn and short-staple cotton yarn, and its elongation is between that of cotton and polyester. Its initial modulus is lower than both cotton and polyester, reflecting the fiber's soft hand feel. The bending stiffness and shear stiffness of polyamide ester are about one-third lower than those of conventional polyester of the same specification, requiring no wrinkle-free finishing. The fabric has good wrinkle resistance. The breaking strength of polyamide ester fiber is similar to that of cotton fiber, and it also helps improve the anti-pilling and anti-fuzzing properties of the fabric.

[0022] The H-shaped cross-section makes it easy for adjacent fibers to come together, and the surface area of ​​the fiber is 20% larger than that of ordinary circular cross-section fibers of the same density. At the same time, based on the capillary principle, the polyamide ester fiber with the H-shaped cross-section can quickly absorb, transport, diffuse and volatilize water, thereby keeping the skin in contact with the fabric dry.

[0023] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
