Problems solved by technology

However, the cost of this method is too high, the selection of fiber materials is too narrow, and it also pollutes the environment
[0008] In the existing production process of superfine fibers, functional additives and dyes are generally processed in two steps, adding functional additives before spinning, and dyeing in the dyeing and finishing process, which not only increases production costs, but also Serious three-waste problems are generated. Therefore, it is of great significance to realize the production process and industrialization of one-step functionalization of ultra-fine fibers

Abstract

The present invention relates to a production method of super fine fibre, in particular it relates to a production method of colored functional super fine fibre. Said production method includes the following several steps: directly mixing super fine fibre raw material with coloring material, adjuvant and functional additive according to a certain mixing ratio to obtain colored anti-bacterial mother materi, melting said mother material at high temperature, extruding said molten mother material by using twin-screw extruder and making basic hydrolysis so as to obtain the invented product.

Description

Technical field: [0001] The invention relates to a production method of superfine fibers, in particular to a production process of colored functionalized superfine fibers. Background technique: [0002] The ways for general textiles to obtain color are: [0003] 1. Fabric dyeing and finishing; [0004] 2. Textile processing after fiber dyeing; [0005] 3. The yarn is dyed before textile processing. [0006] Generally speaking, the dyeing performance of microfiber is very poor, and it can be dyed with disperse dyes, but it usually needs to be carried out under the conditions of high temperature and high pressure or the presence of carriers, which will cause great damage to the fiber, poor color fastness, and the dyeing chromatogram range is relatively narrow. The most important thing is that these dyeing processes all produce a large amount of three wastes, which seriously endanger the environment. [0007] Some people hope to obtain colored fibers by modification. Howev...
