Problems solved by technology

[0003] So far, there are many literatures and products about darkening agents in China, but most of them focus on silicone resin darkening agents. The darkening rate of the darkening agent is 20% to 30%, and the darkening effect is not obvious
Foreign companies in the same industry have mastered a darkening agent for fluorine-containing resins, which has a good darkening effect, but the cost is too high, and for the confidentiality of the technology, the cost of using the domestic dyeing factory is relatively high, which will affect the dyeing factory's understanding of this kind of darkening agent. usability of the product
[0004] The darkening agents on the market are far from meeting the needs of the growing printing and dyeing process due to their high price and too few varieties, especially for dyeing deep black fabrics.

Abstract

The invention provides a deepening agent composition. Preparation raw materials for the deepening agent composition comprise hyperbranched amino silicon oil and modified chitosan in a weight ratio of1 to (0.01-0.2).

Description

technical field [0001] The invention belongs to the technical field of textile printing and dyeing, in particular, the invention relates to a darkening agent composition and a preparation method thereof. Background technique [0002] With the development of the economy, the requirements for environmental protection at home and abroad are getting higher and higher, and the production cost of the dyeing factory is increasing. It is imperative to reduce the amount of dye to reduce the cost. In order to achieve the same dyeing depth, darkening agents came into being. Especially the post-finishing darkening agent has the most practical value. [0003] So far, there are many literatures and products about darkening agents in China, but most of them focus on silicone resin darkening agents. The darkening rate of the darkening agent is 20% to 30%, and the darkening effect is not obvious. Foreign companies in the same industry have mastered a darkening agent for fluorine-containing...
