详细内容
酸性固色剂ColTrit®HS-250N属于磺酸缩合物聚合而成，可与染料构成不溶于水的大分子化合物，从而提高染色物的耐水洗及摩擦等各项牢度，是羊毛﹑尼绒﹑锦纶﹑丝绸﹑皮件等用阴离子染料（酸性染料，金属络合染料）染色之纤维的用固色剂，经处理后的染色物，其皂洗牢度、水洗牢度、汗渍牢度、耐氯牢度等得到大提高，免调酸，使用方便。
物化性质：
化学组成 磺酸缩合物聚合物
外观 深红棕色粘稠液体
离子性 阴离子
PH 2.0-4.0
产品性能：
1.用于用聚酰胺纤维酸性染料染色的后处理，提高酸性染料染色的湿牢度；
2.不影响织物色相、手感，避免常规阳离子固色剂产生固色斑的问题；
3.根据使用的相应染料，能使对日光牢度的影响降至低；
4.可防止印花织物固色时白地沾色；
5.免调酸，使用方便。
ColTrit ® HS-250N
Acid fixing agent ColTrit ® HS-250N belongs to the polymerization of sulfonic acid condensates ａnd can form insoluble macromolecular compounds with dyes, thereby improving the fastness of dyes to water washing ａnd friction. It is a special fixing agent for fibers dyed with anionic dyes (acid dyes, metal complex dyes) such as wool, nylon, silk, leather goods, etc. After treatment, the dyed fabric has soap washing fastness, water washing fastness, ａnd sweat fastness The chlorine resistance ａnd fastness have been greatly improved, acid free, ａnd convenient to use.
Physical ａnd chemical properties:
Chemical composition sulfonic acid condensate polymer
Appearance: Dark reddish brown viscous liquid
Ionic anions
PH 2.0-4.0
Product performance:
1. Used for post-treatment of dyeing with polyamide fiber acid dyes to improve the wet fastness of acid dye dyeing;
2. It does not affect the color ａnd texture of the fabric, ａnd avoids the problem of fixed spots caused by conventional cationic color fixing agents;
3. According to the corresponding dyes used, the impact on sunlight fastness can be minimized;
4. It can prevent the white ground from staining during the fixation of printed fabrics;
5. No acid adjustment, convenient to use.
