Description
Technical Field
The invention relates to a textile finishing solution, in particular to an antiviral and antibacterial finishing solution for high-density polyester-nylon composite fiber fabric. Meanwhile, the invention also provides an antiviral and antibacterial finishing process of the high-density polyester-nylon composite fiber fabric.
Background
The polyester-nylon composite fiber belongs to the extension of nylon or a nylon product, and mainly comprises polyester fiber and nylon fiber, wherein the polyester-nylon composite fiber is formed by shunting a high polymer melt of the polyester fiber and the nylon fiber through a special distribution plate and extruding the high polymer melt through the same spinneret orifice. The monofilament of the polyester-nylon composite fiber belongs to superfine fiber, and the fiber fineness of the polyester-nylon composite fiber can be about 20 times smaller than that of common fiber.
The high-density fabric is a high-grade product in textile products and is also the direction of product development, when the tightness of the fabric exceeds 100%, the secondary coverage area of yarns is generated, even the third coverage is generated, and the tightness of the fabric can reach more than 200% or 300%.
The high-density polyester-nylon composite fiber fabric generally refers to a fabric which is formed by weaving one or more superfine fiber yarns in a circle by a circular machine (or called a knitting machine). It is widely used in: 1. wiping industrial precision instruments and equipment; 2. cleaning and beautifying the inside and outside of the automobile; 3. wiping and cleaning door and window glass, furniture, kitchen and bathroom supplies and the like.
In recent years, as public awareness of health and hygiene increases, antiviral and antibacterial products for controlling viruses and bacteria have been developed and put on the market in various fields. In the textile field, in order to prevent the growth of viruses and bacteria attached to textile fabrics and the generation of odor, functional polyester-nylon composite fiber fabrics with antiviral and antibacterial properties have been developed.
At present, the modification methods of the antiviral and antibacterial fiber fabric are roughly divided into two main types of fibril processing methods and post-treatment processing methods:
the fibril processing method is mainly characterized in that in the spinning stage of synthetic fibers, the antiviral and antibacterial agent is mixed into fiber resin and then spun, so that the antiviral and antibacterial agent can be uniformly dispersed in the fibers. The fiber produced by the fibril processing method has antiviral and antibacterial effects because the antiviral and antibacterial agent is exposed on the surface of the fiber or is partially dissolved out, and when the antiviral and antibacterial agent on the surface of the fiber is reduced, the antiviral and antibacterial agent in the fiber can be diffused outwards to be supplemented, so that the antiviral and antibacterial effects are durable, and the use is safe because the dissolution amount is small. For example, chinese patent publication No. CN1710157A discloses a method for processing antibacterial moisture-conductive polyester fibers, in which modified antibacterial additives are blended with polyester fiber-forming resin to make resin chips; however, the above-mentioned fibrillation processes do not achieve the antiviral and antibacterial effects of the woven fabric.
The post-treatment processing method comprises the following two methods: (1) grafting an antiviral and antibacterial group to a reaction group on the surface of the fiber by adopting a chemical technology, and if the surface of the fiber has the reaction group, reacting the reaction group on the surface of the fiber with an antiviral and antibacterial agent to graft and fix; if the fiber surface does not have a reactive group, the reactive group is required to be introduced, and the antiviral and antibacterial agent is generally fixed on the fiber surface by heat through reactive resin; (2) the physical modification technology is adopted, so that the antiviral and antibacterial agent is adsorbed on the surface of the fiber, and usually the antiviral and antibacterial agent permeates into a deeper position in the surface layer of the fiber; this method is essentially a post-processing finishing technique for fibers, and is mostly due to the antiviral and antibacterial effects caused by the dissolution of the antiviral and antibacterial agents from the fiber surface.
However, when the existing post-treatment processing method is used for modifying the woven high-density polyester-nylon composite fiber fabric, the antiviral and antibacterial agents cannot effectively penetrate the fabric, namely the virus activity and the bacteria breeding cannot be effectively inhibited.
