These dyes are used in Laundries, Prisons, Hospitals, Industrial sites or anywhere that large quantities of cotton, rayon, linen, etc. clothing (like uniforms), rags, towels, or whatever need to be colored or color coded.
The water soluble 8 oz. bags (dyes up to 50 lbs of goods) get thrown into HOT water washing machine load for 15 minutes and then rinsed and washed. The hotter the water you use, the better the color you will get. 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. If you want a professional good looking dye job on your clothes that will last and last, use our Dharma Fiber reactive dye for cellulose fibers (cotton, rayon, hemp, etc.) or our Acid Dyes for wool and silk.
**We also have Industrial dyes for polyester!
- see the related product below. Can be combined with these dyes for natural fabrics to dye fabrics that are polyester blends darker shades. The Polyester dyes are in the same colors as these dyes.
