1. Nylon Ribbon used raw materials quality is not good;
2. The injection temperature in the process is used too high;
3. Baking time in production is too long;
4. In the production of mold cooling and timely cooling does not meet the requirements;
5. The late heat treatment of nylon strap is not enough;
6. Natural oxidation of nylon strap in storage.
The above is the introduction of the reasons for the yellowing of nylon ribbon, because it has certain water absorption and evaporation, usually yellow is because of water evaporation or high temperature caused, so to the nylon strap storage in a cool place, if you use when the problem of brittle, can be put into the warm water soak for 24 hours can restore softness.
