Water-based sizing agent for all-cotton spinning and preparation method thereof

Abstract

The invention relates to a water-based sizing agent for all-cotton spinning and a preparation method thereof. The problems that in the prior art, surface adhesion between water-based sizing agents forall-cotton spinning and cotton fibers is poor, and the tensile property of sizing agents is poor are solved. According to a technical scheme, the water-based sizing agent for all-cotton spinning comprises the following components in parts by weight: 30-40 parts of butyl acrylate, 10-20 parts of methyl acrylate, 10-20 parts of methyl methacrylate, 15-25 parts of acrylonitrile, 10-20 parts of lauryl acrylate, 3-5 parts of a divalent alkaline earth metal compound, 3-4 parts of an emulsifier, 3-5 parts of an initiator, 0.3-0.5 part of an antistatic agent and 1.1-1.9 parts of a penetrant. The acrylonitrile is introduced into a sizing agent monomer, so that the surface adhesive force between the sizing agent and cotton fibers is greatly improved, the sizing rate of the sizing agent is high, andthe antistatic property is good.

Description

technical field [0001] The invention relates to a slurry and a preparation method thereof, in particular to a cotton textile water-based slurry and a preparation method thereof. Background technique [0002] The sizing of high-density fabrics in cotton textiles generally uses acrylic acid-based ternary copolymerization slurry, which has a low viscosity and high solid content, but due to the presence of a certain amount on the molecular chain of the copolymer molecule in the slurry The carboxylic acid groups in the slurries are not neutralized, and it is easy to increase the viscosity during the pulping process. In addition, these sizings also have a relatively general adhesion of the copolymer molecules to the cotton fibers, and the molecular chains are easily stretched. Fracture problem. The publication date is 20171110, and the Chinese patent with the publication number CN107338641A discloses a kind of water-based slurry for textile fabrics. The slurry in this invention h...
