Will rayon thread withstand warm wash water or should I try a different type of embroidery thread?


A good quality rayon thread can withstand high temperatures of wash water; from 140 degrees F for a normal household wash to 203 degrees F for heavily soiled items, as long as detergents contain no bleaching agents, peroxide, or optical brighteners. But if there is any chance that your customer is apt to use bleach, or sell to someone who does, you will be safe by embroidering with a good quality polyester thread.
