Development Of The Green Alkylpolyglucosides Starch Size

The common size for warp sizing mainly contains starch , polyethylene alcohol and acrylic size. Even though PVA has a good sizing property, it pollutes the environment badly. Hence, it is indispensable for us to develop green size to replace the use of PVA when people are concerned about the environmental protection very much.The topic the paper discussed is a kind of new green size—alkylpolyglucosides starch, Alkylpolyglucosides starch size is a new word coming from the green surfactant—"Alkylpolyglucosides". There is no report about alkylpolyglucosides among the varieties of size turned from original starch. There is no study in the area yet.The paper made use of the reaction between starch and butyl alcohol under the condition of the activator, grafed the non-polar group on the first carbon atom of residual glucose of the starch, then made the alkylpolyglucosides starch size. Based on the experiments, the paper chose the parameter of its manufacturing process, including reactive time, ratio of the activator, ratio of the butyl alcohol; the paper also discussed the effect of process parameter to the butyl group content grafed. The paper discussed the effect of manufacturing process parameter to the properties of size, such as viscosity and viscous force ,also the effect of the butyl group content change of alkylpolyglucosides starch size to size properties. The paper drew conclusion in the light of the experimental data; did sizing experiments with alkylpolyglucosides starch size while containing different butyl group content; based on test of strength, abrasion resistance and hairiness, it account for the effect the different butyl group content to the sizing properties of alkylpolyglucosides starch size.The paper also compared the alkylpolyglucosides starch size with phosphate ester starch and acidolysis starch based on the experiment of sizing compatible stability, size properties ,the sizing impact, and it came to the conclusion that the property of alkylpolyglucosides size is superior to the others.The paper also tested the degradative performance. After analyzing the testing result, it concluded that alkylpolyglucosides starch size was a cleanly size.It drew a conclusion at last that alkylpolyglucosides starch size prepared by the optimized process can meet the T/C blended yarn's sizing request absolutely. And its manufacturing material is natural and reproducible, it can be bio-degraded quickly and thoroughly. The alkylpolyglucosides starch size can be used in the textile area undoubtedly.
