Why does Tencel fabric harden after water?

Why does Tencel fabric harden after water? Normal quality will not have this phenomenon. What's more, Tencel raw materials have this kind of defect, but the dyeing and finishing process is not in place. In fact, it is not difficult to solve this problem. In the finishing process, we should strictly do three points. Tencel fabric will not only not harden, but also keep soft and falling, comfortable and comfortable. Once and for all, there will be no worries.

Why does Tencel fabric harden after water? This problem is not inherent in Tencel fabric itself, and it is not complicated to solve. In dyeing and finishing, the following three points are enough.

1. Fully open the fiber. What is fiber opening? In fact, it is to fully open the fiber bundle to make it more fluffy and soft. Tencel Lyocell fiber will expand when it meets with water, which is different from cotton, flax, wool and chemical fiber. The fibers are originally very close. When they meet with water, they will expand more tightly, so they will harden. After finishing, fully open fiber can be avoided.

2. Sand washing. Tencel fabric swells when it meets with water and becomes hard. Sand washing can soften it well, completely eliminate its "edges" and make it flexible and smooth. In fact, Tencel fabric is basically to do sand washing, whether it is machine cylinder dyeing sand washing or air cylinder dyeing, are sand washing principle, so the drape performance will be particularly excellent. In order to reduce the cost, some people use long car dyeing instead of sand washing, so it is inevitable that it will harden in case of water.

3. Add softener. Softener is a kind of auxiliary agent, which can increase the softness and smoothness of Tencel fabric. It not only feels more comfortable and smooth, but also makes its "bone" less hard! It doesn't harden easily in water.

Why does Tencel fabric harden after water? This problem does not need to be considered too complicated, and there is no need to study its principle from the structure of raw materials. It can be easily solved in the finishing. The three methods of opening fiber, sand washing and adding softener can solve this problem. In fact, why Tencel fabric hardens as soon as it passes through the water has long been solved. It's not a problem. It's just the confusion caused by some people in order to cut corners or try to reduce costs.
