摘要
采用1,1,1-三羟甲基丙烷作为增塑剂,以浆膜的断裂伸长率为评价指标,并结合它对淀粉浆料粘度、粘度热稳定性、粘附性等性能指标的影响,研究了三羟甲基丙烷对淀粉浆料的增塑作用,考察了它在经纱上浆中应用的可行性,最后通过实验给出了合理用量.实验结果表明三羟甲基丙烷对淀粉浆料有明显的增塑作用;随着三羟甲基丙烷用量的递增,它对淀粉浆料的增塑作用呈现先增大后减小的趋势.在经纱上浆过程中,三羟甲基丙烷对淀粉浆料的摩尔用量为干淀粉的5%为宜.
In order to seek the plasticizer suitable for plasticizing starch sizing agents so as to solve the problems existing within current plasticization,the plasticization of trimethylolpropane for starch sizing agents was investigated in terms of extension of starch film.In addition,the effects of the plasticizer on paste viscosity,viscosity stability,and adhesion-to-fibers were also considered for evaluating the probability of the plasticizer in warp sizing.Reasonable ratio of trimethylolpropane to starch was determined in accordance with experiments.The results indicated that trimethylolpropane has obvious effect on the plasticization of starch sizing agents.As the ratio of trimethylolpropane to starch increased,the plasticization enhanced initially,reached maximum at the ratio of 5%,and then reduced.It was recommended that reasonable molar ratio of trimethylolpropane to starch in warp sizing operation was 5%based on the experiments.
