Formation of back stain in the garments due to washing is considered as washing defect. Back stain is not acceptable to the buyer. Hence proper precaution should be taken to avoid back stain. The probable reasons of back stain formation due to garments washing are as follows:

  1. Excess use of fabric softener
  2. If garment fabric color is of low quality

To overcome the problem of back stain formation following measures to be taken.

Complete garments washing without softener and observe the back stain. If back stain is not formed, then the reason for back stain formation is for the use of excess amount of softener. Hence use of softener is to be reduced. If back stain is observed then it is clear that the low quality of colored materials present in the garment fabric is the reason of back stain formation.

For low quality color of the garment fabric, the garment needs pretreatment prior to normal wash. The pretreatment is described here. Load 100 kg garments in the washing machine and add 500 liter water @ L:R = 1:5. Add color fixing agent @ 1% that is 1 kg to the liquor and start machine running. Start steam supply to raise temperature to 40 C and continue processing for 10 minutes. Drop the liquor, unload the garments, hydroextrust the garments and then dry the garments in the garment drying machine.
