Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cationic fabrics, in particular to a cationic imitation memory fabric. Background Art
[0002] As the market continues to evolve, people are placing greater emphasis on the comfort and functionality of clothing. Manufacturers of high-end apparel and fashion are placing increasingly diverse demands on fabric performance. Cationic fabrics, a type of all-polyester fabric, are widely used in clothing due to their excellent water absorption, soft feel, comfort, and vibrant colors. High-end clothing often requires the elbows of tops and knees of pants to return to their original shape after arching. Therefore, fabrics with excellent shape retention and the ability to return to their original shape are required, a feature that standard cationic fabrics lack.
[0003] Memory fabric refers to fabric with shape memory function, that is, the fabric has the property of returning to its original shape after being deformed by external factors. It is a good choice for making suits, windbreakers, jackets, etc. Therefore, it is necessary to develop a cationic memory fabric. Utility Model Content
[0004] The purpose of the utility model is to provide a cationic imitation memory fabric, which aims to solve the problems raised in the above background technology.
[0005] In order to solve the above technical problems, the purpose of the utility model is achieved as follows: a cationic imitation memory fabric, comprising: a wear-resistant layer, an antibacterial layer and an antistatic layer composited in sequence; the wear-resistant layer is interwoven by a first warp yarn and a first weft yarn; the first warp yarn has a shape memory polyurethane fiber filament as a core, and cationic polyester fiber filaments are spirally wound on the outside; the first weft yarn has a shape memory polyurethane fiber filament as a core, and nylon fiber filaments are spirally wound on the outside; the antibacterial layer is interwoven by antibacterial shape memory core-spun yarn; the antistatic layer is interwoven by antistatic shape memory core-spun yarn.
[0006] On the basis of the above solution and as a preferred solution of the above solution: the cross-section of the cationic polyester fiber filament is pentagonal.
[0007] On the basis of the above solution and as a preferred solution of the above solution: the antibacterial shape memory core-spun yarn has shape memory polyurethane fiber filaments as the core and is wrapped with modified flax fibers on the outside.
[0008] On the basis of the above solution and as a preferred solution of the above solution: the antistatic shape memory core-spun yarn has shape memory polyurethane fiber filaments as the core and antistatic polyester fiber filaments are spirally wound on the outside.

[0010] The beneficial effects of the utility model are as follows: based on the cationic imitation memory fabric of the utility model, shape memory polyurethane fiber filaments are used to make the fabric have the functions of arch recovery and wrinkle recovery. After the fabric is deformed under the influence of external factors, it has the property of being able to return to its original shape. The wear-resistant layer enhances the wear resistance of the fabric and resists pilling, thereby extending the service life of the fabric; the antibacterial layer can inhibit the growth of microorganisms and play an antibacterial and mildew-proof role; the antistatic layer avoids static electricity generated by friction during wearing of the fabric, thereby improving the comfort of the wearer. BRIEF DESCRIPTION OF THE DRAWINGS
[0011] Figure 1 This is a schematic structural diagram of the cationic imitation memory fabric involved in the present utility model;
[0012] In the figure: 1-wear-resistant layer, 2-antibacterial layer, 3-antistatic layer. DETAILED DESCRIPTION
[0013] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.
[0014] Combine Figure 1 This embodiment is described in detail. A cationic imitation memory fabric comprises: a wear-resistant layer 1, an antibacterial layer 2 and an antistatic layer 3 composited in sequence; the wear-resistant layer 1 is interwoven by a first warp yarn and a first weft yarn; the first warp yarn has a shape memory polyurethane fiber filament as a core, and cationic polyester fiber filaments are spirally wound on the outside; the first weft yarn has a shape memory polyurethane fiber filament as a core, and nylon fiber filaments are spirally wound on the outside; the antibacterial layer 2 is interwoven by antibacterial shape memory core-spun yarn; the antistatic layer 3 is interwoven by antistatic shape memory core-spun yarn.
[0015] The shape-memory polyurethane filaments can be produced by various spinning processes, including dry spinning, wet spinning, melt extrusion, or chemical reaction. These temperature-sensitive shape-memory fibers possess the physical and mechanical properties of conventional fibers, while also exhibiting a wide temperature response range and excellent shape memory properties. Fabrics containing these fibers exhibit features such as arch recovery and wrinkle recovery, providing added aesthetic value and comfort to the wearer.
[0016] Furthermore, the cationic polyester fiber filament has a pentagonal cross-section. Cationic polyester is made by introducing cationic groups into the polyester molecular chain, allowing the fiber to be dyed with cationic dyes at room temperature and pressure. Compared to conventional polyester, cationic fibers exhibit better color fastness and brighter colors. Fibers with a pentagonal cross-section have a soft luster and excellent resistance to pilling and fuzzing.
[0017] Nylon fiber filaments have excellent wear resistance, good elasticity, and fatigue resistance, and their fabrics have good wearing properties. Specifically, in this embodiment, the nylon fiber filaments are UV-resistant nylon fiber filaments, which are synthesized from cyanuric chloride, resorcinol, and n-butyl bromide as raw materials to synthesize the triazine UV absorber 2,4,6-tris(2'-hydroxy-4'-butoxyphenyl)1,3,5-triazine, and then the UV absorber is blended with nylon 6 chips and melt-spun to obtain the product. The protection value of the UV-resistant nylon fiber filaments can be as high as 68.25, and the UV protection value can still reach 51.89 after washing 20 times, showing good UV resistance and washability.
[0018] Furthermore, the antibacterial shape-memory core-spun yarn comprises a core of shape-memory polyurethane filaments wrapped with modified flax fibers. Specifically, the modified flax fibers are pre-treated using a low-concentration alkali scouring method, followed by ultrasonic-assisted modification using a scutellaria baicalensis extract and a tannic acid solution. Scutellaria baicalensis is a commonly used herbal medicinal plant, rich in active ingredients, with excellent antibacterial effects against Staphylococcus aureus, Escherichia coli, and Candida albicans. It also contains a variety of flavonoids that scavenge free radicals and inhibit microbial growth, achieving antibacterial and mildew-proof properties. Furthermore, Scutellaria baicalensis itself is non-toxic and harmless to the human body.
[0019] Furthermore, the antistatic shape-memory core-spun yarn comprises shape-memory polyurethane filaments as the core, with antistatic polyester filaments spirally wound around the outside. The antistatic polyester filaments are produced by melt-spinning the fiber by adding a high-molecular-weight permanent antistatic agent to the base polymer. The antistatic agent is blended or copolymerized with the base polymer, imparting the fiber with inherent antistatic properties. This long-lasting antistatic effect enhances wearer comfort when woven into fabrics.
[0020] Furthermore, the wear-resistant layer 1, the antibacterial layer 2 and the antistatic layer 3 are compounded by dot-shaped hot melt adhesive.
[0021] The above describes in detail the preferred embodiments of the present invention. It should be understood that those skilled in the art can make numerous modifications and variations based on the concepts of the present invention without inventive effort. Therefore, any technical solutions that can be derived by those skilled in the art based on the concepts of the present invention through logical analysis, reasoning, or limited experimentation based on the existing technology should be within the scope of protection defined by the claims.
