詳細內容
酸性固色劑ColTrit®HS-250N屬于磺酸縮合物聚合而成，可與染料構成不溶于水的大分子化合物，從而提高染色物的耐水洗及摩擦等各項牢度，是羊毛﹑尼絨﹑錦綸﹑絲綢﹑皮件等用陰離子染料（酸性染料，金屬絡合染料）染色之纖維的用固色劑，經處理后的染色物，其皂洗牢度、水洗牢度、汗?jié)n牢度、耐氯牢度等得到大提高，免調酸，使用方便。
物化性質：
化學組成 磺酸縮合物聚合物
外觀 深紅棕色粘稠液體
離子性 陰離子
PH 2.0-4.0
產品性能：
1.用于用聚酰胺纖維酸性染料染色的后處理，提高酸性染料染色的濕牢度；
2.不影響織物色相、手感，避免常規(guī)陽離子固色劑產生固色斑的問題；
3.根據使用的相應染料，能使對日光牢度的影響降至低；
4.可防止印花織物固色時白地沾色；
5.免調酸，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.
