Green printing and dyeing auxiliary agent and preparation method thereof

Abstract

The invention discloses a green printing and dyeing auxiliary agent and a preparation method thereof. The green printing and dyeing auxiliary agent comprises 3-9 parts of an ethylene oxide-propylene oxide copolymer, 2-4 parts of amino polysiloxane, 1-3 parts of amide ethyl imidazoline, 3-5 parts of ethylene oxide, 1-3 parts of diester quaternary ammonium salt, 10-14 parts of polyacrylamide, 5-9 parts of sodium sulfite, 1-3 parts of sodium carbonate and 1-3 parts of a nonionic surfactant. The invention belongs to the technical field of printing and dyeing auxiliary agents, and particularly provides the green printing and dyeing auxiliary agent which is healthy in raw material, environment-friendly and pollution-free, has good color protecting and color increasing functions on textiles, enables the textiles not to fade easily, and improves the flexibility and color fixing performance of the textiles, and the preparation method of the green printing and dyeing auxiliary agent.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing auxiliaries, and specifically refers 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...

Problems solved by technology

Due to the simplicity of the chemical surfactant group, each surfactant has a single role. Therefore, as many as a dozen surfactants are often used in each printing and dyeing process, and the addition amount is large, which increases the cost. In addition, , chemical printing and dyeing auxiliaries are difficult to be biodegraded, easy to damage the ecosystem and pollute surface and groundwater, which have a greater impact on the environment, and often have health toxicity, so many printing and dyeing auxiliaries fall into the "green barrier" restriction category

There are many new printing and dyeing auxiliaries in the prior art, but these printing and dyeing auxiliaries all have single performance and are not easy to resist acid, alkali, oxidant and high temperature, the performance of color enhancement and color protection is not ideal, the color fastness is not enough, and it is easy to fade, which is harmful to the skin. There are defects such as irritation
