Let's see how polyester yarn is transformed from DTY to colored polyester yarn. Color fastness is a very important indicator of the yarn product.This takes place at King Win, a yarn manufacturer and yarn supplier producing high-quality polyester and nylon yarn.

After the dyeing process, the yarn would be the required color, which has been confirmed by the customer. However, is it easy to fade or in a great colorfastness level? In other words, whether the is qualified or not. All we need to do is having a check. How? There is a simple but rude way - boiling.

If the yarn color isn't fade after boiling, that means the yarn is on level 4 to 5 of colorfastness, and it's very important for the customer to make their perfect final product so that the friction force can be obtained along the length of the fiber.
