Embodiment 1

[0031] The dirt-resistant and antistatic dirt-resistant treatment method of nylon fiber fabric modification treatment method comprises the following steps:

[0032] (1) Nylon fiber fabrics need to be soaked in deionized water, ethanol, acetone and n-hexane in order to be fully cleaned before modification, and then dried for use. Subsequently, the pre-dried nylon fiber fabric sample is placed in a plasma processor, and the power is adjusted to 300W, so that the nylon fiber fabric is treated for 2 minutes on each side under an oxygen atmosphere to obtain a hydrophilic nylon fiber fabric;

[0033] (2) Add 10ml of ethanol, 0.1g of ferric chloride, 1ml of 1H,1H,2H,2H-perfluorooctyltriethoxysilane into the weighing bottle, stir well, then add the nylon treated in step (1) Immerse the fiber fabric for 2 minutes, take it out and dry it at room temperature for 1 hour;

Abstract

The invention relates to a modified fiber fabric and a preparation method thereof. According to the preparation method, a flexible fluorine-containing chain segment is anchored by a method for in-situ growth of a conductive polymer multi-level roughness micro-nano structure on the surface of a fabric. According to the invention, the nylon fiber fabric can be endowed with lasting stain resistance, and the antistatic performance can be additionally introduced.

Description

technical field [0001] The invention belongs to the field of functional fabrics and its preparation, in particular to a modified fiber fabric and its preparation method. Background technique [0002] Nylon fiber fabric has the advantages of high strength, good toughness, durability, wear resistance, and strong air permeability, and is an important class of synthetic polymer materials. However, due to the strong polarity of the amide bond, nylon has strong hygroscopicity and poor stability, and is not resistant to dirt, which limits its wider application fields. Therefore, the modification of nylon fiber fabrics, especially the surface modification, is very important. Common stains are divided into liquid stains (water and oil) and solid stains. At present, there have been many researches on the surface hydrophobic modification of nylon fiber fabrics, but there are few researches on the surface oleophobicity and solid stain resistance. reports. Among them, liquid pollution...
