In sum, in the traditional preprocessing technology, must use following chemical products and auxiliary agent: NaOH, hydrogen peroxide solution, scouring agent, bleeding agent, hydrogen peroxide bleaching stabilizer etc., its interpolation is numerous in variety, operates loaded down with trivial detailsly, and technological process is long, length consuming time, and energy consumption is high.
Traditional handicraft is because of using a large amount of caustic soda (being NaOH), and is not only big to fibre damage intensity, and processing finishes the back for making the not residual alkali lye of fabric, needs big water gaging flushing, and the generation sewage quantity is big.And the alternative most caustic soda of scouring enzyme of our company's invention can effectively address the above problem.
Because good multi-fibre is to alkali sensitivity or non-refractory, the pre-treatment of multi-component fibre fabric bleaching is difficult, for example: and the bleaching of cotton/wool blended textile fabric or intertexture is bigger to the loss of hair; The bleaching of cotton/nitrile blending or intertexture, acrylic fibers are easy damaged and yellowing under the highly basic hot conditions.
Tradition hydrogen peroxide solution bleaching technology weak point is following: oxygen steam steams (or boiling) technology; Need to reach about 1 hour in high temperature (95-100 ℃) processing; Could accomplish discoloration, not only energy consumption is high, and also bigger to the damage of fiber; The fabric ultimate strength descends obviously about more than 15%, and the degradation rate of cellulose fibre is about 40-50%.The hydrogen peroxide solution cold-pad-batch process, the amount of padding is little, the time of banking up is short, and the fluctuations of variation of ambient temperature and wash conditions etc. are bigger to the influence of bleaching effect, and quality stability can not be said satisfactory.
