Jacquard Synthrapol Industriële sterkte vloeibaar wasmiddel 8 oz

This did exactly what it was intended to do.

This product has few uses, but my goodness does it EVER work!! In short:1. Prewashing fabrics/garments to be dyed, definitely recommended.2. AFTER dye rinse/wash- this stuff suspends the excess dye particles, keeping them out of the fabric as you rinse.3. Subsequent washing of home-dyed items, it prevents massive colour loss as well as stopping the runoff from staining other items in the wash.If you dye fabric at home, or especially if you do tie-dye, this is your very best friend.

Great for soaking wool before dyeing. Just a teaspoon or so in your soaking tub does the trick.

I love using this product when washing delicate silks. It’s hard to find.

Easy to use and really did soften the yarn of my hand knitted Nordic cardigan
