Problems faced by Lyocell fiber replacing viscose fiber

The core problem of Lyocell fiber replacing viscose fiber is cost performance. Compared with viscose fiber, Lyocell fiber outstanding advantages are non-polluting production process and excellent physical properties. However, the advantages of clean production process will not be directly reflected in the use value of the product, the huge social benefits brought by clean production can be used as a highlight of product promotion, but for most customers, people are more concerned about its use value. Therefore, the high strength of the clean production process and Lyocell fiber, especially the high wet strength, is difficult to reflect in the product price; In addition, viscotic fiber in spinning, weaving and other aspects have a very perfect production equipment and technology, can be used in the vast majority of occasions are very good, the fabric also has Lyocell fiber similar moisture absorption, softness and wearing comfort, and the price is much lower than Lyocell fiber. 

The high strength of Lyocell fiber is beneficial for improving the spinning and weaving speed, but it has a limited impact on the overall price throughout the process. High-strength fibers can prepare thinner clothing, the use of more durable, on today's popular clothing view, fashion is the key, a piece of clothing due to high strength and wear more than a few years is not necessarily a good thing, for the vast majority of use occasions, do not need fibers have such high strength. In other words, in the field of consumption, the high strength of Lyocell fiber is not fully utilized. In addition, Lyocell fiber also has a single variety and easily fibrillated short plate.

Lyocell fiber with the continuous increase in production, equipment manufacturing costs will have a significant decline, the further optimization of the process, the increase of single-line capacity and the development of new varieties will effectively reduce production costs and increase the added value of products, all these factors will promote the rapid development of Lyocell fiber, but these work are not immediately able to achieve. Its development needs to have a long process. The development trend of Lyocell and viscose fiber will continue for at least ten or even twenty years, and Lyocell fiber and viscose fiber will exist in parallel for a longer time.

Therefore, the development of Lyocell fiber can not be placed on the disappearance of viscotic fiber, the development of Lyocell fiber but also rely on its own technological progress, the fundamental way out is to improve the cost performance of fiber and develop new application areas.
