Abstract

The invention relates to an environment-friendly emulsion-like textile size composition and a preparation method and application thereof. The composition is prepared from, by weight, 80-100 parts of adhesive, 1-8 parts of thickening agent and 10-45 parts of microcapsule powder. The adhesive is a mixture of acrylonitrile, methyl acrylate, butyl acrylate, methyl methacrylate, acrylic acid, methacrylic acid and acrylamide. The thickening agent is an associative type waterborne polyurethane thickening agent or a polyacrylic acid type synthetic thickener so that the viscosity of the composition at 25 DEG C can be adjusted to be 11-13 centipoises. The textile size composition is mainly used as paint for textile, the technical problems that the textile is hard in handfeel, poor in crock fastness, not high in rubbing fastness, high in after-dyeing textile hardness, poor in viscosity and pollutes the environment are solved, and the effects of being excellent in crock fastness, high in rubbing fastness, soft in after-dyeing textile handfeel, good in after-dyeing textile hydrophilia, especially excellent in adhesive force and friendly to the environment in the production process are achieved.

Description

technical field [0001] The invention relates to the technical field of textiles, in particular to an environment-friendly emulsion textile size 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 fastn...
