What is the difference between Tencel and Modal？

1. The raw materials are different.
First of all, Tencel and Modal are both wood pulp fibers at the same time, so they are very similar in performance characteristics. The modal of the Austrian Lenzing company is about 10 years old beech wood. Tencel is mainly made of coniferous trees, which have a higher content of lignin fibers.
2. The spinning principle is different.
The viscose wet spinning process adopted by Modal uses a large amount of chemicals such as caustic soda, sulfuric acid, sulfur dioxide, zinc sulfate and other chemicals to alkalize, age, dissolve, yellow, and filter the wood pulp raw materials during the spinning process. reaction.
Tencel adopts a more environmentally friendly solvent production process. The conifer-based wood pulp and organic amine oxide solvent are mixed and heated to completely dissolve, and no derivatives and chemical reactions are produced during the dissolution process. It is more environmentally friendly and does not pollute the ecology.
This process is particularly complicated. Viscose is the first generation wood pulp fiber, Modal is the second generation wood pulp fiber, and Tencel is the third generation wood pulp fiber. In fact, this is how it came.
3. Different fiber characteristics.
Modal fiber has a relatively uniform inner and outer layer structure, and the skin-core structure of the fiber cross-section is not as obvious as that of ordinary viscose fibers. Excellent performance.
The morphological structure of lyocell fiber is completely different from that of ordinary viscose. The cross-sectional structure is uniform and round, and there is no skin-core layer. The longitudinal surface is smooth without grooves, and has superior mechanical properties than viscose fibers.
