Aramid fiber dyeing process and system

Abstract

The invention relates to the technical field of aramid fiber dyeing, in particular to an aramid fiber dyeing process and system. The aramid fiber dyeing process comprises the steps of S1, loading aramid fiber materials to be dyed into an aramid fiber dyeing system sequentially, and performing material preparation; S2, putting the prepared aramid fibers into the aramid fiber dyeing system; S3, controlling an electric field in the aramid fiber dyeing system to be in a changing state for dyeing; S4, realizing dyeing through cooperation of a moving magnetic field and ionization; S5, in the dyeingprocess, enabling the aramid fibers to be continuously kneaded and extruded in the aramid fiber dyeing system; S6, before dyeing is finished, enabling the dyed aramid fibers to be subjected to preliminary color fastness sampling detection regularly to judge the current dyeing condition; S7, after the dyeing condition meets the requirement, enabling the dyed aramid fibers to be subjected to deep color fixing treatment; and S8, drying the aramid fibers subjected to color fixation, and collecting the dried aramid fibers for later use. The aramid fiber dyed by the process is good in dyeing effect,high in color fastness and relatively high in dyeing uniformity.

Description

technical field [0001] The invention relates to the technical field of aramid fiber dyeing, in particular to an aramid fiber dyeing process and system. Background technique [0002] Aramid fiber is a new type of high-tech synthetic fiber with excellent properties such as ultra-high strength, high modulus, high temperature resistance, acid and alkali resistance, and light weight. 2 to 3 times that of fiber, toughness is 2 times that of steel wire, and the weight is only about 1 / 5 of steel wire. It does not decompose or melt at a temperature of 560 degrees. It has good insulation and aging resistance. very long life cycle. [0003] Due to the many advantages of aramid fiber, the use of aramid fiber in civilian products is gradually increasing with the development of market technology. In the manufacture of aramid fiber products, it is necessary to present different colors of the product, so it is necessary to dye the aramid fiber to be used as the raw material for production...

AI Technical Summary

Problems solved by technology

In the manufacture of aramid fiber products, it is necessary to present different colors of the product, so it is necessary to dye the aramid fiber to be used as the raw material for production, but due to the characteristics of the aramid fiber, the adhesion effect is usually poor during dyeing and it is easy Discoloration and discoloration will seriously affect the later use effect and the aesthetics of the product
