涤粘交织物低碱低温碱减量工艺
|
摘要
研究了Na OH、苯甲醇和促进剂1227的添加量,以及温度和时间对涤粘(T/R)交织物减量率的影响,并通过SEM观察织物形貌。结果表明,随着Na OH、苯甲醇和促进剂1227添加量的增加、碱减量温度的升高和时间的延长,T/R织物的减量率增加。在Na OH 5 g/L,苯甲醇30 m L/L,促进剂1227 1.5×10-4mol/L,100℃保温100 min或Na OH 2.5 g/L,苯甲醇45 m L/L,促进剂1227 1.5×10-4mol/L,100℃保温85 min的条件下,织物的减量率可控制在10%左右,但强力有所下降。
The effects of the concentrations of sodium hydroxide, benzene methanol and accelerant1227, as well as alkali deweighting temperature and time on deweighting rate of T/R fabrics are discussed, and the morphology of T/R fabric is observed by SEM. The results show that the deweighting ratio of T/R fabrics increases with the increasing of sodium hydroxide, benzyl alcohol or accelerant 1227 concentrations, alkali deweighting temperature and time. Under the conditions of alkali deweighting at100 ℃ for 100 min with sodium hydroxide 5 g/L, benzyl alcohol 30 m L/L and accelerant 1227 1.5×10-4 mol/L,or alkali deweighting at 100 ℃ for 85 min with sodium hydroxide 2.5 g/L, benzyl alcohol 45 m L/L and accelerant 1227 1.5×10-4 mol/L, the deweighting rate of T/R fabrics can be controlled at about 10% with a little decrease in the strength of the T/R fabric.
