竹浆纤维的防缩抗皱整理

为更好地说明竹浆纤维缩水变形的原因,测试了竹浆纤维及其纱线的性能.采用2步法:第1步在碱质量浓度为150 g/L、水温为30 ℃、时间为2 min的条件下对竹浆纤维绞纱进行松弛碱处理,取出后用质量分数为2%的H2SO4(含Zn"、Mg2+)溶液中和5 min,获得初步的防缩水效果;第2步是对竹浆纤维织物进行树脂整理.讨...

Crease and shrink resistant finishing of bamboo viscose fibers

For better understanding the cause which leads to the shrinking and deformation of bamboo viscose fibers, the properties of bamboo viscose fibers and their yarns were tested with two-step method. Firstly, slack alkali treatment of bamboo viscose fiber hank was performed under the conditions: mass concentration of alkali 150g/L, treating at 30℃ for 2min, followed by neutralization treatment with mass concentration of 2% H2SO4(Zn2+，Mg2+), treating for 5min, thus preliminary shrink resistant effect was obtained. Secondly, resin finishing of bamboo viscose fiber fabric was carried out. The effect of the dosage of finishing agent on the crease recovery angle, shrinkage, formaldehyde content, whiteness, bursting strength, and hand feeling of knitted sweaters made of the finished bamboo viscose fiber fabric was investigated. Through analyzing experimental data and charts, the optimal finishing process was determined as follows: glutaraldehyde resin (low-temperature self-crosslinking easy-care finish) 60g/L, catalysts 20 g/L, strong protective auxiliary 50g/L, softener SAPAMINE®HS 10g/L。
