支直比对接枝淀粉浆料性能的影响
|
摘要
为了考察支直链淀粉含量对接枝淀粉浆料性能的影响,以纯支链、纯直链淀粉为原料,用相对于淀粉含量40%的单体丙烯酸、乙酸乙烯酯(1∶1)对支直比分别为10∶0、7∶3、5∶5、3∶7、0∶10的混合支直链淀粉进行接枝共聚,并结合偶氮二异丁酸二甲酯和硝酸铈铵作为引发剂,得到接枝淀粉浆料。通过测试不同支直比下的接枝淀粉浆料对纯棉(40S)、涤棉(45S)纱线的黏附力以及淀粉膜的机械性能得出:当支链含量低于70%时,随着直链含量的减少,接枝淀粉浆料对纯棉、涤棉粗纱的黏附力增大;当支链含量超过70%时,呈现相反趋势,且接枝淀粉浆料支直链比例的变化对涤棉粗纱的影响大于纯棉粗纱;随着直链含量的增加,接枝淀粉膜的机械性能增加。
In order to investigate the effect of amylose content on the properties of grafted starch size, branched chain starch and amylose were used as raw material, and mixed branched amylose which proportion of branched chain starch and amylose were at 10:0, 7:3, 5:5, 3:7 and 0:10, respectively, was graft copolymerized by methacrylic acid, and acetic acid vinyl ester, which proportion was 1:1, and equal to 40% of starch content. Butyric acid two methyl ester and ammonium cerium nitrate were used as initiator to obtain grafted starch size. The adhesive force of grafted starch size to pure cotton(40 S), polyester/cotton(45 S) and the mechanical properties of starch film were tested. Results indicated that when the content of the branched chain was less than 70%, the adhesion of the grafted starch sizing agent to the cotton and polyester/cotton roving increased with the decrease of the content of the straight chain; When the content of the branched chain exceeded 70%, the adhesion of the grafted starch sizing agent declined. And the change of the ratio of the amylopectin had a larger impact on polyester/cotton roving than that of the cotton roving. With the increase of the straight chain content, the mechanical properties of the graft starch film are increased.
