Abstract

The invention relates to a slurry composition for the sizing of yarns or textile fibers, and a preparation method and applications thereof. The slurry composition comprises the following raw materials in parts by weight: 80 to 100 parts of adhesive, 1 to 8 parts of thickening agent, and 10 to 45 parts of microcapsule powder, wherein the adhesive is a core-shell type hydrophobic (meth)acrylate copolymer, the thickening agent is an association type aqueous polyurethane thickening agent or an acrylic acid synthesized thickening agent, and the thickening agent can adjusting the viscosity of the slurry composition to 11 to 13 centipoises at a temperature of 25 DEG C. The provided slurry composition is mainly applied to sizing of yarns or textile fibers, and can solves the problems of hard hand feeling, bad rubbing fastness, bad washing fastness, high hardness after dyeing, bad adhesive force, and environment pollution of textiles. The processed yarns or textile fibers have the advantages of excellent rubbing fastness, high washing fastness, soft hand feeling after dyeing, good hydrophilicity after dyeing, and strong adhesive force, and the production process is environment-friendly.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to a size composition for sizing yarn or textile fibers, 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, esp...
