Acid-proof anti-yellowing hook-and-loop fastener and preparation method thereof

Abstract

The invention discloses an acid-proof anti-yellowing hook-and-loop fastener and a preparation method thereof. The preparation method of the acid-proof anti-yellowing hook-and-loop fastener comprises the steps of conducting dip dyeing, cleaning and finishing through a cleaning and finishing agent; dehydrating the cleaned chinlon hook-and-loop fastener, and whitening the chinlon hook-and-loop fastener in a whitening finishing liquid; dehydrating the chinlon hook-and-loop fastener subjected to whitening finishing; preparing an anti-oxidation finishing agent, and carrying out anti-oxidation finishing on the chinlon hook-and-loop fastener; carrying out acid-proof anti-yellowing coating on the finished chinlon hook-and-loop fastener; and drying the sprayed chinlon hook-and-loop fastener. According to the acid-proof anti-yellowing hook-and-loop fastener and the preparation method thereof provided by the invention, the acid-proof anti-yellowing hook-and-loop fastener is good in acid-proof performance, the acid-proof anti-yellowing coating adhesive is safe, odorless, not prone to falling off, and lasting in effect, the hook-and-loop fastener is high in strength and difficult to permeate and erode by acid liquor or other chemicals, and damage to the hook-and-loop fastener is greatly reduced.

Description

technical field [0001] The invention relates to the field of Velcro processing technology, in particular to an anti-acid and anti-yellowing Velcro and a preparation method thereof. Background technique [0002] Velcro, also known as Velcro, mother-in-law buckle, is composed of hook fabric with small hooks and wool fabric with plush threads. Based on the convenience of bonding and separating, the hook and loop is widely used in clothing, medical, sports, aviation and other fields. The raw materials of hook and loop fasteners mainly include polyester and nylon. At present, the longest used raw material of hook and loop fasteners is nylon. When using the Velcro in clothing, it is tightly connected, easy to put on and take off, and widely used. As an acid-resistant tool fastener, its strength in acidic medium is very important. Ordinary nylon hook and loop fasteners in acidic medium have reduced rigidity, serious strength loss, and the fastening effect cannot be exerted, which...
