There are many accessories used in garments such as zippers, buttons, elastic, motif, level, etc. These accessories may be damaged or partially damaged during garment dyeing, which is not acceptable. To save these accessories from being damaged, some special chemical is used during garment dyeing. These chemicals are used in different stages of dyeing.
Special Chemical Used in Garments Dyeing:
There are different types of special chemicals used in Garments garment-dyeing process. Today, I would like to discuss the special chemicals used in garment dyeing. The application of different chemicals is described below.
Special Chemical Used in Garments Dyeing
1. Desizing agent:
Bacterial alpha amylase base desizing is better in sizing step. Because the stability of enzyme activity is not affected bactasol, biolase are such type of desizing agent.
2. Wetting agent:
Desizing is very important for garments dyeing process. Main purpose of desizing is to remove sizes materials from garments. Non-ionic wetting agent improves the desizing effect than other wetting agent.
3. Scouring and Bleaching agent:
There are oil, wax, rceding, pectose and mineral impurities in cotton fiber. These should be removed during the scouring and bleaching process. If there removed impuritic, from the insoluble compound, may again be re-deposited on the fiber surface, which may cause spots on fabric. To avoid such problems, sandopan LFN or sirrix AK liquid may be used.
4. For Saving Al:
In garments, Al is used as zipper and button accessories. Present of Aluminum may be damaged by the action of alkali during process, sandoclear 8160 or sandopan SF liquor may be used for overcoming the problem.
5. For Blended fabric:
Nowadays blended fabric is mostly used for garments fabric manufacturing process. If cotton and nylon blended fabrics used, then Lanalbin PA powder is used to save nylon fabric during scouring and bleaching steps.
6. For Crease Formation:
The formation of crease is a common problem in garment dyeing. To avoid crease formation on fabric imacol is used as lubricant in the dyeing bath.
7. For Irregular Dyeing:
Irregular dyeing may occur in the cuff, pocket area during garments garment-dyeing process. Here, Drimagen E2R of Clarinet Company may be used to minimize the problem.
