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.

Abstract

The invention provides a preparation method of an anti-pilling agent for blended fabrics. First, isooctyl methacrylate, hydroxyethyl methacrylate, sodium secondary alkyl diester sulfonate, nonionic emulsifier and quantitative de-pilling Ionized water is mixed with a pH regulator, stirred evenly to make a pre-emulsion, and then quantitative deionized water is added to the initiator after heating up, and the pre-emulsion is added dropwise at the same time. Polymerized emulsion of methacrylate; secondly, the siloxane monomer and the silane coupling agent are sheared at high speed to obtain A uniformly, and after adding deionized water, sulfonic acid, pepinga and polyethylene glycol to mix, add A dropwise after heating up , then stirred and then heated up and kept warm, then lowered to room temperature, added a pH regulator and mixed to obtain a silicone polymer emulsion. Add the two and isomeric tridecanol polyoxyethylene ether into the mixing tank, stir and mix evenly. The invention improves the anti-fluffing and pilling grade of the fabric, has little influence on the handle of the fabric, and 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...
