Preparation method of anti-pilling agent for blended fabrics

Abstract

The invention provides a preparation method of an anti-pilling agent for blended fabrics. The preparation method comprises the following steps of adding isooctyl methacrylate, hydroxyethyl methacrylate, secondary alkyl diester sodium sulfonate, a nonionic emulsifier and a certain amount of deionized water into a pH regulator, mixing, uniformly stirring to prepare a pre-emulsion, heating the certain amount of deionized water, adding an initiator, dropwise adding the pre-emulsion at the same time, keeping the temperature after dropwise adding, and then cooling to room temperature, so as to obtain a polymerization emulsion of methacrylate; secondly, uniformly shearing a siloxane monomer and a silane coupling agent at a high speed to obtain A, adding deionized water, sulfonic acid, peregal and polyethylene glycol, mixing, heating, dropwise adding A, stirring, heating, keeping the temperature, cooling to room temperature, adding the pH regulator, and mixing to obtain the organic silicon polymerization emulsion; and adding the polymerization emulsion of methacrylate and the organic silicon polymerization emulsion and iso-tridecanol polyoxyethylene ether into a mixing kettle, and uniformly stirring and mixing. The anti-pilling grade of the fabric is improved, the influence on the hand feeling of the fabric is relatively small, and the anti-pilling agent is easy to store.

Description

technical field [0001] The invention relates to an environment-friendly anti-pilling agent for textiles, which is mainly used for anti-pilling of acrylic and wool blended fabrics. Background technique [0002] Cashmere fabric is widely loved by consumers due to its soft feel, thick and plump suede surface, soft luster, and good warmth retention. However, cashmere fabrics are limited by raw materials, and the cost remains high. Acrylic fiber has the advantages of good hand feeling, low cost, easy availability of raw materials, and good warmth retention. The cashmere-like fabric made of acrylic fiber and wool blend has broad market prospects. [0003] However, when the wool is rubbed by the outside world, the fiber ends are pulled out to form loops and fluff, and the fluff is formed on the surface of the fabric to make the cloth surface lose its luster. Long and retracted and tangled into a ball. One end of the resulting pompom is embedded in the fibers of the fabric and at...

Problems solved by technology

[0004] The anti-pilling agents currently on the market are mainly film-forming substances, but pure film-forming substances will make the fabric feel harder, which requires the addition of softeners to improve the fabric feel. Most of these anti-pilling agent emulsion products are For a single wool or cashmere fabric, CN103044627A discloses a wool fabric anti-pilling emulsion and a preparation method thereof, and its anti-pilling is mainly aimed at wool fabric; CN107663770A discloses a cashmere anti-pilling auxiliary agent, It is aimed at cashmere products

However, these additives are not ideal for the anti-pilling effect of cashmere-like fabrics blended with wool and acrylic fibers

When the composition of the film-forming substance and soft substance of the auxiliary agent is changed to meet the requirements of blending, the problem of incompatibility often occurs when the two are mixed, and it is easy to cause delamination after being placed, so it cannot be used for industrial use.
