The Difference Between Tencel And Lyocell

Tencel and Lyocell are both man-made fibers, which are widely used in the textile industry. Although they are both man-made fibers, there are some differences between them. This paper will make a detailed comparison between Tencel fiber and Lyocell fiber from the following aspects: raw materials, production technology, performance characteristics, application fields, etc.

1.Ingredients

Tencel is a kind of fiber made from natural wood pulp, and its raw materials mainly come from renewable plants such as eucalyptus and poplar. Lyocell fiber is a kind of lignin as a raw material, its raw material sources include hardwood, cork, bamboo and other renewable plants.

2.Production process

The production process of tencel mainly includes pulp preparation, dissolution, spinning, solidification, drawing, finishing and other steps. In this process, tencel is produced using the solvent method, that is, cellulose is dissolved by an organic solvent and then spun into fibers by wet spinning technology. The production process of Lyocell fiber is similar to tencel, including pulp preparation, dissolution, spinning, solidification, drawing and other steps. However, Lyocell fiber uses dry spray wet spinning technology, that is, no organic solvent is used in the spinning process, but the cellulose solution is sprayed by high-pressure air, and then solidified into fiber in a coagulation bath.

3.Performance characteristics

Tencel fiber has the following characteristics: high moisture absorption, permeability, softness, skin affinity, antistatic and so on. Because its raw material is derived from natural plants, tencel fiber has good biodegradability and is friendly to the environment. Lyocell fiber also has similar performance characteristics, such as high moisture absorption, air permeability, softness and so on. In addition, Lyocell fiber also has good wear resistance and wrinkle resistance, as well as high strength and elongation.

4.Application field

Tencel fiber and Lyocell fiber are widely used in the textile industry. They can be used to make a variety of textiles, such as underwear, outerwear, bedding, towels, etc. In addition, they can also be used to make non-textiles, such as paper, medical supplies, etc. Due to their good environmental performance, Tencel and Lyocell fibers are increasingly in market demand in the context of sustainable development and green consumption.

5.Price

Because the production process of tencel fiber is more complex, and the raw material comes from natural plants, its price is relatively high. The production process of Lyocell fiber is relatively simple, and the raw material sources are wide, so its price is relatively low. However, with the development of technology and the increase of market demand, the price of Lyocell fiber is gradually decreasing.

In short, although Tencel and Lyocell fibers are man-made fibers, they have certain differences in raw materials, production processes, performance characteristics and so on. Tencel fiber is made of natural plants and has good biodegradability and environmental protection performance. With lignin as raw material, Lyocell fiber has high wear resistance and wrinkle resistance. In practical applications, suitable fiber materials can be selected according to specific needs.
