Preparation method of polyester fabric with water-and-oil repellent and anti-bacterial functions

Abstract

The invention discloses a preparation method of a polyester fabric with water-and-oil repellent and anti-bacterial functions. The method comprises the following steps of A, carrying out surface modification treatment on a polyester fabric in an atmospheric-pressure dielectric-barrier discharge plasma device; B, putting the polyester fabric into a solution for in-situ generation of a TiO2 / Ag nanocomposite structure and drying the TiO2 / Ag nanocomposite structure; C, fully oscillating and padding the polyester fabric in a super-hydrophobic functional finishing liquor; and D, pre-baking and bakingthe polyester fabric through an oven to prepare a water-and-oil repellent, anti-fouling and anti-bacterial polyester fabric. According to the method, an anti-bacterial function is combined with a water-and-oil repellent function, the TiO2-Ag nanocomposite structure is constructed in situ on the surface of a polyester fiber by adopting a sol-gel method, and atmospheric-pressure plasma treatment iscombined with fluoroalkyl silane treatment, so that the polyester fabric has stable super-hydrophobic anti-bacterial property, has good stability of mechanical friction resistance, is efficient, energy-saving and environment-friendly in an operation process, has less impact on other physical properties of the fabric and has good development space, and continuous industrial production is easy to achieve.

Description

technical field [0001] The invention relates to the technical field of polyester fabric preparation, in particular to a preparation method of polyester fabric with water, oil, and antibacterial functions. Background technique [0002] With the improvement of living standards, people have higher and higher requirements for fabric quality, especially for fabric functionality. The water and oil repellent finishing of the fabric is to form a low tension film on the surface, which cannot be wetted by water or oil, so as to achieve the effect of water and oil repellency. Water-repellent and oil-repellent finishing generally has the following methods: (1) Compact waterproof and moisture-permeable fabric: it is tightly woven with superfine fibers to achieve the purpose of water repellency, but it can only prevent water penetration for a short time, and it does not have oil repellency. Crack performance is poor, feel hard. (2) PTFE film lamination: the product processing is difficu...

Problems solved by technology

Water-repellent and oil-repellent finishing generally has the following methods: (1) Compact waterproof and moisture-permeable fabric: it is tightly woven with superfine fibers to achieve the purpose of water repellency, but it can only prevent water penetration for a short time, and it does not have oil repellency. Poor cracking performance, hard feel

(2) PTFE film lamination: the product processing is difficult, the cost is high, the price of the garment is expensive, and its softness and drapability are poor

(3) Coating finishing: based on organic solvent system, the environmental pollution is heavy, and the drape and softness of the treated fabric become worse, the finishing effect is poor in durability, and the adhesion fastness is low

(4) Finishing by fluorocarbon padding method: after finishing, the whiteness of the fabric is reduced, waste water is generated during the finishing process, and energy consumption is serious
