Q
do you need salt or vinegar to dye polyester
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
Dyeing polyester requires specific methods due to its synthetic nature. Traditional salt or vinegar additives used in dyeing natural fibers like cotton or wool are ineffective on polyester. Instead, polyester demands disperse dyes and high heat to ensure the color adheres to the fibers. Disperse dyes are specifically designed for synthetic fibers, facilitating the bonding process under heat—often through boiling or using a dye carrier in a dye bath. Therefore, when dyeing polyester, the key is using the correct dye type and heat application rather than relying on salt or vinegar.
