when i bring home new fabric i first wash it in vingar water about one cup in the waqshing machine. this sets the dye and keeps it from fading for many years i also do this with new cloths my grand ma taught me this trick. she said they had to do that in the old days
this is also how you set the dye when tie dying fabrick if your material can go in hot water it sets it faster and better

I have heard of using vinegar , but never knew why . Thanks for the info :thumbup:

So do you rinse in clear water after the vinegar wash? Just wondering about the acid in the vinegar if you don't rinse.

I was also wondering about how much vinegar to use. Perhaps 1 cup by medium load?

Vinegar works to set some organic dyes. Modern dyes are not organic though and vinegar doesn't have any effect one way or the other.

great tip. I wonder if this would work on batiks

Interesting.

It sure couldn't hurt. Consider it an ounce of prevention.

I was taught to do it. (I just turn the jug up and pour. Probably 1/2 cup to a full tub of water). I let the fabric (clothes, unsewn fabric) set in it at least 1/2 hour. If I am not in a hurry I will let it set longer. It may not make a difference with the newer fabrics but it makes me feel like a winner. !!!.

do you use white vinegar or apple cider vinegar?
