If the Fiberglass Cloth is browned, can it be used normally?

The normal color of Fiberglass Cloth is white, but in the production process of Fiberglass Cloth, sometimes it will appear yellow, that is to say, the white is mixed with some yellow. This yellow color is not artificial or deliberately filled in. And this is also uncontrollable. Sometimes the temperature will be difficult to control after a long time of production.

At the same time, yellow spots will appear when the temperature suddenly rises. So if the Fiber Glass is baked and turns yellow, will there be any impact? After we passed constant tests, we found that when it turns brown, it basically has no impact on our normal use. It just has some impact on appearance. If you are using it yourself, this will not affect anything.
But if it is sold, there will be some impact. This is also a project that we are trying to control as much as possible. We have made a lot of improvements during the recent production process, replacing coal-burning furnaces with electric furnaces, so that the temperature can be well controlled. I remember that a customer once sent me a sample, which was roasted yellow. The customer said that the color was very beautiful, so he wanted to buy it.
