Description

Technical Field

[0001] The utility model relates to a washable antibacterial nylon fabric, belonging to the technical field of textile fabrics. Background Art

[0002] Microorganisms such as bacteria can multiply in large numbers in a suitable environment. Various types of textiles used in daily life are prone to adsorb various impurities in the gas, liquid and solid phases, becoming a breeding ground for bacteria. In the long run, these bacteria will cause textiles to discolor, mold, become brittle, degrade, etc. In severe cases, they will also irritate human skin and induce a variety of diseases. There are currently two methods for producing antibacterial products. One is to add a specific antibacterial agent to the spinning solution and mix it with a fiber-forming polymer to spin antibacterial fibers, and the other is to obtain it through an antibacterial finishing method. Nylon refers to the general term for thermoplastic resins containing repeated amide groups -NHCO- in the main chain of the molecule. Because nylon-based fibers have excellent mechanical properties, resilience, wear resistance and fatigue resistance, they are widely used in the fiber field. Fabrics with fluff on the surface are also popular because of their soft touch surface effect and can be used in warm clothing. Adding antibacterial ingredients in the preparation process of nylon fibers can make nylon fabrics have a washable and lasting antibacterial effect. The pile fabric made of nylon fiber combines the advantages of nylon fabric and pile fabric, but the pile of the existing pile fabric will fall down after being rubbed, forming smear marks.

[0015] Figure 2 It is a schematic diagram of the cross-sectional structure of a single filament in the nylon 6 multifilament involved in Example 1.

[0016] The markings in the figure are as follows: 1-surface layer; 2-inner layer; 3-fluff layer; 11-fiber body; 12-protrusion. DETAILED DESCRIPTION

[0017] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0018] Embodiment 1

[0019] Combination Figure 1 and Figure 2 The present embodiment is described in detail. The washable antibacterial nylon fabric of the present embodiment comprises a surface layer 1 and an inner layer 2 connected by a binding weft yarn; the surface of the surface layer 1 away from the inner layer 2 has a fluff layer 3 formed by warp raising.

[0020] The surface layer 1 is formed by interweaving nylon 6 core-spun yarn in a satin weave, and the inner layer 2 is formed by interweaving bio-based nylon 56 core-spun yarn. The nylon 6 core-spun yarn includes a first core yarn and a wrapping yarn wrapped around the outside of the first core yarn, the core yarn includes linen yarn, the wrapping yarn includes antibacterial nylon 6 multifilament, and the cross section of the monofilament in the antibacterial nylon 6 multifilament includes a straight-line fiber body 11 and protrusions 12 symmetrically arranged on both sides of the fiber body 11.

[0021] In the surface layer 1, specifically, 8 pieces of 3-fly satin weave are interwoven. The satin weave has good softness. When the surface layer 1 is fluffed, the wrapped yarn is fluffed to form the fluff layer 3. The cross-sectional shape is a slender flat structure, which is very similar to the shape of a caterpillar and has good uprightness, so that the fiber can stand up quickly after bending. The fluff in the fluff layer 3 can stand up quickly after lodging.

[0022] The bio-based nylon 56 core-spun yarn includes a second core yarn and a covering fiber layer covering the outside of the second core yarn, the second core yarn includes antibacterial nylon 6 filaments, and the covering fiber layer is antibacterial bio-based nylon 56 fiber.

[0023] Furthermore, the binding weft yarn is an antibacterial nylon 6 filament with a cross-shaped cross section. Since the cross-shaped cross-section fiber has grooves on the surface, the antibacterial nylon 6 filament has a moisture absorption and perspiration effect through the wicking effect.

[0024] Furthermore, the antibacterial nylon 6 filament and the antibacterial nylon 6 multifilament are obtained by adding an antibacterial agent to a molten nylon 6 slice and then extruding it. The antibacterial bio-based nylon 56 fiber is also obtained by adding an antibacterial agent to a molten bio-based nylon 56 slice and then extruding it. The added antibacterial agent can be nano zinc oxide particles.

[0025] Embodiment 2

[0026] The washable antibacterial nylon fabric involved in this embodiment is different from that in the first embodiment in that the first core yarn also includes a coral grass fiber yarn twisted with a linen yarn. The coral grass fiber is a natural plant fiber, which is made by blending and spinning the effective ingredients extracted from the leaves of the natural plant coral grass with viscose, has a natural antibacterial effect, and the antibacterial rate reaches more than 99%, which exceeds the national requirements for antibacterial fabrics.

[0027] Another difference from the first embodiment is that the second core yarn also includes hygroscopic heat-generating fiber yarn and far-infrared fiber yarn twisted with the antibacterial nylon 6 filament. The hygroscopic heat-generating fiber yarn and far-infrared fiber yarn can improve the warmth-keeping effect of the fabric in different ways.

[0028] The preferred specific embodiments of the utility model are described in detail above. It should be understood that ordinary technicians in this field can make many modifications and changes based on the concept of the utility model without creative work. Therefore, all technical solutions that can be obtained by technicians in this technical field based on the concept of the utility model through logical analysis, reasoning or limited experiments on the basis of the existing technology should be within the scope of protection determined by the claims.
