Cotton Fabric Scouring Agent Preparation And Performance Study At Low Temperature

This article tires rfom the basic principle of the three methods of low temperature shows itsprocessing methods, advantages and disadvantages, and its development trend, and through theexperimental study on distirbution of a new type of fertilizer X for cotton fabric pretreatment, Iintended to reduce the pollution to the environment at the same time improve the efficiency of thepretreatment, providing a better basis for subsequent dyeing, at the same time reduce the cost.First, this paper mainly studied the low temperature scouring agent BY-LR, the lowtemperature scouring agent ZS₁193and the high temperature scouring agent RY-09，such astheir alkali resistance, foamability, ionic, permeability, etc., and compares them with conventionaltraditional process. Through the test of their whiteness and capillary effect of the besttechnological process, the best process for BY-LR low temperature scouring agent is:2g/L,45。C，35min; the best process for Guoguang ZS-1193low temperature scouirng agent is:3g/L,65°C,20min; The best technology for RY-09high temperature scouirng agent is:2.5g/L,95。C，50min.Second, choosing the reactive dye of black ED-H, the reactive dye of navy blue ST-RH todyeing the auxiliaries processed cotton fabrics. Respectively after tested them for cotton dyeing ofresidual liquid absorbance, atfer soaping and night of absorbance, K/S value. By comparing withdata analysis, finally the strategy of scouring choose Guoguang ZS-1193low temperature scouringagent as the best pretreatment auxiliaries.Finally, the paper compound with a Guoguang ZS-1193low temperature scouring agent toinvent a similar functionality low temperature scouring agent X.Select T05（Fatty alcohol polyoxyethylene ether），T07（Heterogeneous fatty alcohol polyoxyethylene ether） and SA-35（degreaser） as the main components of the scouring agent X at low temperature. Through thetest after the pretreatment of cotton fabric whiteness, Capillary effect, we can get the X lowtemperature scouirng agent composition,determine the best group is divided into: T056%, T076%, SA-356%, NaOH1.25%. And test the low temperature scouring agent X with alkaliresistance, foamability and ion permeability properties. By testing cotton dyeing after the residualliquid absorbance, after soaping and night of absorbance, K/S value, determine the optimumprocess for color: dosage of concentration of2.5g/L,45°C,35min.
