Application Of Lyocell Fiber

The application of Lyocell fiber should give full play to its own characteristics.

High hygroscopic property is its essential feature, it gives the fabric good wear performance, therefore, it is very suitable for the manufacture of clothing, especially high-end clothing, because of its high modulus, so that the fabric has excellent conformal property.

In addition, the use of its high hygroscopicity and high strength can be made of denim series of clothing. In the past, denim was made of cotton, but cotton was low in strength and did not wear well. The high strength of Lyocell fiber is the ideal material for making denim.

Lyocell fibers are biodegradable and, therefore, ideal for the manufacture of disposable sanitary materials. At present, many viscose fibers have been used in nonwoven fabrics, but because of the low strength of viscose fibers, especially the low wet strength, the performance of the final product is low. Using the high strength of Lyocell fiber, ultra-short Lyocell fiber made of collapsible nonwovens has appeared on the market.

Compared with viscose fiber, due to the high crystallinity of Lyocell fiber, the initial temperature of thermal decomposition is higher than that of viscose fiber, the thermal weight loss is less, the dynamic modulus changes little, the fiber strength reduction is less, the elongation at break can also meet the processing and use requirements, has good heat resistance, and the thermal shrinkage rate is low, and the combustion condition is basically the same as that of viscose fiber. When Lyocell fiber is kept at 190℃ for 30min, the breaking strength and elongation at break of the fiber are 88.4% and 88.6% of the original value, respectively, showing good heat resistance.
