Problems solved by technology

[0003] However, the fabrics treated with traditional fluorine-containing fabric finishing agents will reduce the waterproof effect as the use time increases, and the fabric color will be destroyed during the fabric finishing process, making the fabrics yellow. Not high, most of them need to be imported, increasing the production cost

Abstract

The invention discloses a manufacture method of a waterproof cotton-nylon blended fabric. The manufacture method comprises the following steps of in sequence: sequentially adding fluoroalkyl acrylic ester, oxyalkylene monomethyl acrylate epoxy alkyl ether, alkylacrylate, dodecyl dimethyl benzyl ammonium chloride and a mixed solvent to a reaction kettle; feeding inert gas into the reaction kettle for performing protection; dropping sodium sulfate under a stirring condition; maintaining the temperature and reacting for 4 to 5 hours, thus obtaining the hybrid emulsion; mixing the hybrid emulsion with water to obtain finishing liquor; placing the cotton-nylon blended fabric into the finishing liquor to finish in a two-soaking and two-rolling way; drying; and roasting, so as to obtain the waterproof cotton-nylon blended fabric. With the adoption of the mode, the cotton-nylon blended fabric manufactured by the manufacture method provided by the invention has long-acting and effective water proofing effect, is high in air permeability and washing fastness, has no color difference occurring before and after finishing, is low in manufacturing cost, provides guarantee for finishing, and can be widely applied to waterproof outerwear fabrics, window curtains, clothes, carpets and work clothes.

Description

technical field [0001] The invention relates to the field of textile fabrics, in particular to a method for manufacturing a waterproof cotton-nylon blended fabric. Background technique [0002] With the development of textiles at home and abroad and the needs of people's lives, people are no longer satisfied with textiles with a single function, and textiles with multiple functions are more and more popular. The fabric finishing agent used in the process of textile finishing can improve the surface properties of the fabric, so that the fabric has various special properties such as waterproof and oil-proof, flame retardant, and soft. Fluorine-containing fabric finishing agents rely on their excellent waterproof and oil-proof properties , breathability, washability and anti-fouling properties have attracted much attention. Fabrics finished with fluorine-containing fabric finishing agents are widely used in rainproof outerwear fabrics, curtains, clothing, carpets and work cloth...
