Abstract

The invention discloses a green printing and dyeing aid which is prepared from the following components in parts by weight: 15-25 parts of alkyl glycoside modified amino silicon oil, 5-10 parts of silicyl benzsulfamide-acrylic copolymer, and 5-10 parts of fatty alcohol polyoxyethylene ether sodium sulfate. A preparation method for the green printing and dyeing aid comprises the following steps: uniformly mixing alkyl glycoside modified amino silicon oil, silicyl benzsulfamide-acrylic copolymer, and fatty alcohol polyoxyethylene ether sodium sulfate, and stirring for 3-4 hours at a temperaturebeing 50-60 DEG C, thereby obtaining a green printing and dyeing aid finished product. The green printing and dyeing aid has the characteristics of being remarkable in uniform dyeing effect, high in color firmness, good in acid and alkaline resistance, good in hand feeling, not liable to fade, and free of stimulus on skin of a human body, has self-degrading ability, is safe, green and environmentally friendly in use.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing auxiliaries, in particular to a green printing and dyeing auxiliaries and a preparation method thereof. Background technique [0002] In recent years, with the rapid development of the textile industry, the demand for dye chemicals is increasing. The interdependence between the dye industry and the textile industry means that China's dye industry has a huge market prospect. Textiles involve printing and dyeing processes in the preparation process, and when textiles with poor color fastness encounter water, sweat, sunlight, saliva or physical friction, the dyes are easy to fall off and fade, affecting the appearance, and the fallen dye molecules or heavy metals Ions may be absorbed by the human body through the skin and pose a threat to people's health. Therefore, in the printing and dyeing process, the method of adding printing and dyeing auxiliaries is often used to improve the dyein...
