Abstract

The present invention relates to a cation hybrid sol and a firm for increasing clarity and firmness of textile printing, which belongs to the textile chemical industry field. The present invention is characterized in that solvent, cation compound, precursors and deionized water are added into a reaction vessel in turn, after being agitated and evenly mixed, catalyst is added into the mixture, and agitated under room temperature and cation hybrid sol is obtained. After diluting the cation hybrid sol and deionized water as per specified ratio, a textile is padded and finished in the sol, and the finished textile is dried. The present invention can improve the anti-bleeding performance of the ink color printing of the textile; and clarity, depth and vividness of color of the ink color printing products are increased; paint/pigment on the textile can be fixed, meanwhile, the combined effect of the cation hybrid sol and paint/pigment make aggregation for fixation of the paint/pigment, and color firmness of the textile color printing is increased.

Description

technical field [0001] The invention relates to a cationic hybrid sol and a method for improving printing clarity and fastness, and belongs to the technical field of textile chemical industry. Background technique [0002] With the development of modern science and technology, materials with a single performance can no longer meet people's needs. At present, composite materials with excellent performance can be prepared by complementing and optimizing the functions of two or more materials, so they have broad application prospects. Organic-inorganic hybrid materials are composite materials combining inorganic materials and organic materials at the nanometer scale, and there is a strong force between the two phases or an interpenetrating network structure is formed. Because it combines the properties of organic polymer materials and inorganic materials, it can overcome the limitations of a single organic or inorganic material, and at the same time present many new properties...
