改性剂预处理棉织物的黑色活性染料染色

研究了棉织物用聚环氧氯丙烷胺化物改性时,改性剂用量、烧碱用量、改性温度及时间对改性织物染色K/S值的影响,讨论了改性织物染黑色时盐和碱的用量,并对改性和未改性染色织物的乌黑度、上染率、K/S值及染色牢度作了比较。结果表明,棉织物经改性后染黑色乌黑度高,K/S值以及上染率均有较大提高,耐洗和耐摩擦牢度好。

Modification of cotton fabric and its dyeing with black reactive dyes

The effect of modifier amount,NaOH concentration,treating temperature,and duration of treatment on the dyeing K/S value of the cationized cotton fabric was researched when cationic modification of the cotton fabric was implemented with polyepichlorohydrin-amine(PECH-amine).The appropriate amount of salt and alkali for dyeing the modified cotton fabric black was discussed,and a comparison of the dyed fabrics of the modified and unmodified was made in terms of blackening,dye up-take,K/S value,and color fastness.The results demonstrate that the cationized cotton fabrics after being dyed black have excellent blackening,considerable improvement in K/S value and dye up-take,and better washing and rubbing fastness.
