Problems solved by technology

[0003] At present, the silicone oils that are widely used in the market have many shortcomings such as yellowing of plants, discoloration, reduction of whiteness, poor stability, moisture absorption (perspiration) and antistatic properties of easy-to-stain fabrics, so in order to keep up with the market needs and application conditions, the existing technology needs to be updated and improved

Abstract

The invention relates to a hydrophilic aminosilicon oil, and a preparation method and uses thereof. The preparation method comprises the following steps: carrying out an addition reaction of hydrogen-containing silicon oil and an oxy-group-containing compound in the presence of a catalyst to prepare epoxy modified silicon oil, and carrying out a quaternary copolymerization addition reaction of the epoxy modified silicon oil, an amino compound, a silane coupling agent and polyether to prepare the novel hydrophilic aminosilicon oil. When the hydrophilic aminosilicon oil is used for finishing polyester and pure terylene fabrics, excellent soft and smooth hand feelings are obtained, and the hydrophilicity, the moisture (sweat) absorption property and the antistatic performance of the fabrics are improved; and the performances of the hydrophilic aminosilicon oil are better than that of hydrophilic aminosilicon oil sold in the market at present, so the hydrophilic aminosilicon oil prepared in the invention has a broad market prospect.

Description

technical field [0001] The invention relates to the field of fabric softening and finishing agents, in particular to a hydrophilic amino silicone oil and its preparation method and application. Background technique [0002] People's requirements for clothing are not simply to require fabrics to be hygroscopic, breathable, and comfortable to wear, but also to pursue soft, smooth, and elegant styles of fabrics. Therefore, softeners appear, and the most widely used ones today are Silicone softener. Silicone softeners were first researched, developed and applied in European and American countries, and made huge profits. Since the reform and opening up, my country's economy has developed rapidly, and the textile printing and dyeing industry has developed from the use of silicone softeners to the gradual application, and now it is fully applied. my country has joined the WTO for many years, and the most competitive industrial products in the international market are textile prod...
