Abstract

The invention discloses a finishing method of a chinlon hydrophobic fabric based on butyl titanate, and belongs to the field of functional textiles. The fabric is pre-treated by employing 1,2,3,4-butanetetracarboxylic acid (BTCA) to increase the reaction capacity of the fabric and subsequent chemical reagents to play a bridging role; butyl titanate can be hydrolyzed and poly-condensed in the presence of water to form granular substances, so as to exert the functions of roughening the fabric; the surface energy of the fabric can be effectively reduced by long-chain alkane octadecylamine; and meanwhile, the environmental problem caused by total fluoride energy is avoided. Traditional dipping, rolling, drying and baking processes are adopted for finishing; the product uniformity, the repeatability and the cost are low; the BTCA, butyl titanate and octadecylamine adopted in the overall finishing process need to be applied in a weak acid or weak base condition; the baking temperature is low; the damages to the fabric are small; and the method can be applied to hydrophobic functional finishing of the chinlon fiber.

Description

technical field [0001] The invention relates to a method for finishing nylon hydrophobic fabrics based on butyl titanate, which belongs to the field of functional textiles. Background technique [0002] Among the many finishing methods, hydrophobic materials are receiving more and more attention in people's daily life and industrial production due to their excellent hydrophobic properties. For example: self-cleaning, clothing for medical staff, high-end clothing, outdoor clothing, etc., hydrophobic materials have played an important role. As a synthetic material, nylon itself is a polyamide fiber, and the hydrogen bonds between molecules make it easy to crystallize. Because of its good flexibility, high elastic recovery rate, high strength, high stability to alkali, good wear resistance and moth resistance, nylon is widely used and continuously developed. As the first industrialized synthetic fiber in the world, it is also one of the main types of chemical fibers. How to c...
