改性羊毛织物超细涂料染色性能

对羊毛织物进行阳离子改性,并用自制阴离子型高分子分散剂制备的超细涂料采用浸染方法对其进行染色。探讨了预处理条件如阳离子试剂浓度、处理浴pH值、处理温度及时间对染色性能的影响。结果表明,涂料浸染羊毛织物的干、湿摩擦牢度可分别达到3~4级和4级;断裂强力和断裂伸长率随处理浴pH值的升高有所下降;弯曲刚度和弯曲滞后的测试表明改性羊毛织物染色后手感柔软,弹性良好。

Dyeing property of the modified wool fabric with superfine pigment

The wool fabric was modified by cationic reagent and dyed with superfine pigment which was prepared by researchers themselves with anionic polymer disperser with exhaust method.The influence of pretreatment conditions such as concentration of cationic reagent,pH value of the bath,temperature and duration of treatment on the dyeing property of the fabric was studied.The results show that the dry and wet rubbing fastness of the wool fabric dyed with pigment via exhaustion is gray scale ratings of 3～4 and 4 respectively.The tensile strength and elongation at break decrease slightly with the increase of bath pH value.The test results of bending rigidity and hysteresis of bending reveal that the wool fabric has soft handle and good elasticity.
