摘要
研究不同程度改性田菁胶的上浆效果。将天然高分子田菁胶通过NaC lO氧化降解,使其成为分子量相对较小的分子,对降解后的不同浓度改性田菁胶的黏度进行了测试,并对比了改性田菁胶和PR-Su、PVA浆出纱线的强伸性能、毛羽数和耐磨性能。试验表明:浓度为1.5%的改性田菁胶上浆综合效果较理想。认为:田菁胶经过NaC lO氧化降解后可以用于纺织上浆。
Sizing effect of different modified sesbania gum were studied. Natural polymer sesbania gum were oxi- dized by NaCIO to become relative smaller molecular. Viscosities of different density modified sesbania gum were tested. Strength and elongation,hairiness and wear-resistance of the yarn sized by modified sesbania gum,PR-Su and PVA were contrasted. The tests prove when modified sesbania gum density is 1.5% ,the sizing effect is better. It is considered that sesbania gum oxidized by NaCIO could be used as textile size material.
