Abstract
The invention relates to a modified fiber fabric and a preparation method thereof, wherein the preparation method comprises the following steps: the method for in-situ growth of the conductive polymer micro-nano structure with multilevel roughness on the surface of the fabric is used for anchoring the flexible fluorine-containing chain segment. The invention not only can endow the nylon fiber fabric with durable stain resistance, but also can additionally introduce antistatic performance.
Description
Technical Field
The invention belongs to the field of functional fabrics and preparation thereof, and particularly relates to a modified fiber fabric and a preparation method thereof.
Background
The nylon fiber fabric has the advantages of high strength, good toughness, durability, wear resistance, strong air permeability and the like, and is an important synthetic polymer material. However, due to the strong polarity of amide bonds, nylon has strong hygroscopicity and poor stability, is not resistant to dirt, and limits the wider application field of the nylon. Therefore, the modification of nylon fiber fabrics, especially the surface modification, is very important. Common stains are divided into liquid stains (aqueous stains and oily stains) and solid stains, and at present, a lot of research works on hydrophobic modification treatment of the surface of nylon fiber fabric are carried out, but researches on oleophobicity of the surface and stain resistance of the solid stains are rarely reported. Where liquid stains depend on the surface tension of the liquid and the critical surface tension of the fabric, while solid stains are generally attracted by electrostatic attraction.
In recent years, due to the application prospects of amphiphobic materials in the aspects of dirt resistance, self-cleaning and the like, people pay attention to the amphiphobic materials, but the construction of the amphiphobic surfaces is difficult, and the surface chemical components and the rough structures of the materials are indispensable key factors. The water-repellent and oil-repellent finishing of nylon fiber fabrics by adopting fluorine-containing fabric finishing agent (n (C)) and (e.g. perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS) and the like has been favored by the market. However, their extreme durability, bioaccumulation, and various toxicities to the human body and the multiple organs of the organism have been prohibited from being used in commercial products.

The preparation method improves the washing fastness of the fabric by plating the silver film layer on the polypyrrole, although the silver film layer attached to the outer layer can slow down the damage to the polypyrrole layer, the cost is high, the silver film layer is easy to wear and fall off, the polypyrrole layer in the polypyrrole layer is polymerized by dipping, the adhesion force with the substrate is weak, and the polypyrrole layer is not wear-resistant at the same time.
