These dyes are used in Laundries, Prisons, Jails, Hospitals, Industrial sites or anywhere that large quantities of cotton, rayon, linen, etc. clothing, rags, towels, or whatever need to be colored or color coded.
The water soluable 8 oz. bags (dyes up to 50 lbs of goods) get thrown into hot water washing machine load for 15 minutes and then rinse. Wash out excess dye with
Synthrapol or laundry detergent and hot water. That's it! Use 1 lb. per 100 lbs. of fabric. No mess, no fuss, no brainer!
The Black dye works great for returning black clothes to their original blackness.
The results are not as long-term washfast or as bright as our other dyes, but these are easy & cheap.
