Special aqueous slurry for nylon spinning and preparation method thereof

Abstract

The invention provides special aqueous slurry for nylon spinning and a preparation method thereof. The special aqueous slurry is high in water solubility, high in permeability, high in antistatic property, high in cohesive force, capable of improving traction force of nylon silks coated with slurry, resistant to wearing, clear in opening, free from slurry shedding, convenient to use, low in environmental pollution, and capable of decreasing the slurry removing cost of a plant in after-treatment process as well as reducing the environmental influence. The special aqueous slurry for the nylon spinning comprises a monomer mixed liquid, supporting materials and process water, wherein the monomer mixed liquid comprises 16kg of acrylic acid, 29kg of hydroxymethyl acrylamide, 190kg of butyl acrylate, 269kg of methyl acrylate, 254kg of methyl methacrylate, and 10kg of lauryl acrylate; the supporting materials include 3kg of an emulsifying agent, 6kg of an initiator, 8kg of a defoaming agent, 3kg of an antistatic agent, 16kg of a penetrant, 50kg of an ammonia water, and 300kg of ethyl alcohol.

Description

technical field [0001] The invention relates to the technical field of textile sizing formulations, in particular to a special water-based slurry for nylon textile and a preparation method thereof. Background technique [0002] Textile sizing is a key link in the weaving process. The purpose of sizing is to improve the wear resistance of yarns. At present, textile sizing is mainly divided into three categories: starch, polyvinyl alcohol (PVA), and polyacrylic acid. Occupy an important position; but there are some problems, such as polyvinyl alcohol slurry cannot be biodegraded, which has caused serious environmental protection problems; starch slurry has large viscosity fluctuations and poor gelatinization performance; and polyvinyl acid slurry has serious re-viscosity, Strong adhesion to fibers, unstable sizing, and difficulty in subsequent desizing, resulting in higher costs for finishing plants and a greater impact on the environment.

[0003] The Chinese patent with the application number CN201510788266.1 discloses a textile water-based slurry and its preparation method. The textile water-based slurry includes a monomer mixture, small materials, and process water. The monomers include 16kg of acrylic acid and 56kg of methacrylic acid. , 190kg butyl acrylate, 269kg methyl acrylate, 254kg methyl methacrylate and 8kg n-butyl. This slurry is suitable for weaving high-grade fabrics and has good water solubility, permeability, antistatic property and cohesion. However, there are certain limitations in the application of nylon
