粘合剂及预处理对锦纶织物印花性能的影响

Effect of adhesive and pretreatment on printing property of polyamide fabric

为了提高锦纶织物酸性染料直接印花的表观色深值和减轻后道水洗任务重的负担,采用对锦纶织物预处理和印花色浆中加入粘合剂的直接印花方法,考察了3种粘合剂(粘合剂DT、粘合剂S-60和粘合剂SD-H)和4种预处理剂(OS-15、尿素、固色剂SD-2、固色剂SD-3)对印花锦纶织物皂洗前后K/S值、K/S比值和色牢度的影响。结果表明,在汽蒸固着条件下,当增稠剂PTF-A为2%,粘合剂S-60为1%时,能获得较好的色深和色牢度。固色剂SD-3的预处理能使印花织物获得优良的色深和色牢度,而其余3种预处理剂(OS-15、尿素、固色剂SD-2)的效果较差。这为开发减轻甚至免除皂洗的锦纶酸性染料直接印花提供了实践参考。

In order to improve the apparent color depth value of polyamide fabric which is directly printed by acid dyes and reduce the burden of washing,this paper used pretheatment of polyamide fabric and direct printing process with adhesive to study the effect of the three kinds of adhesive agents（ adhesive DT,adhesive S-60 and adhesive SD-H） and four pretreatment agents（ OS-15,urea,the fixing agent SD-2 and SD-3） on the K/S values,K/S ratio and color fastness. The result shows that better color depth and color fastness could be gained under steaming fixation condition when the thickener PTF-A was 2%,and the adhesive S-60 was 1%. The pretreatment of fixing agent（ SD-3） could make the printed fabric obtain excellent color depth and color fastness,while other three pretreatment agents（ OS-15,urea,fixing agent SD-2） were less effective. This paper provides practical reference to reduce or even relieve soaping for direct printing of polyamide fabric with acid dyes.
