Abstract

The invention relates to a sizing composition as well as a preparation method and application thereof. The composition is prepared from the following raw material ingredients in parts by weight: 80 to 100 parts of bonding agents, 1 to 8 parts of thickening agents and 10 to 45 parts of microcapsule powder, wherein the binding agents are core-shell hydrophobic (methyl) acrylate copolymers; the thickening agents are associative waterborne polyurethane thickening agents or polyacrylic acid type synthetic thickening agents so that the viscosity of the composition is regulated to 11 to 13 centipoises at the temperature of 25 DEG C. The pulp composition for yarn or textile fiber sizing provided by the invention is mainly used as paint to be used for yarn or textile fiber sizing; the technical problems of hard fabric hand feeling, poor friction fastness, low scrubbing fastness, high fabric hardness after dyeing, poor adhesive force and environment pollution can be solved, so that the effects of excellent friction fastness, particularly high scrubbing fastness, soft hand feeling after dyeing, good fabric hydrophilicity after dyeing, particularly strong adhesive force and environment-friendly effect in the production process are achieved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a slurry composition and a preparation method and application thereof. Background technique [0002] Traditional paint dyeing is to make the paint into a dispersion liquid, make the fabric uniformly liquid by padding, and then treat it at high temperature, with the help of the adhesive, a layer of transparent and tough resin film is formed on the fabric, so that the paint mechanically The coating itself has no affinity for the fiber. [0003] As a kind of pigment, paint has been widely used in printing for a long time. In recent years, due to the continuous improvement of the performance of printing and dyeing auxiliaries (such as adhesives), the application range of paint has been expanded, and the dyeing process of paint has been developed rapidly. Paint dyeing also has shortcomings, such as mechanical fixation determines its rubbing fastness, especially the rubbing fastness ...
