How to produce smooth Tencel Lyocell fabric?
Calender can make hairiness stick on the cloth surface, giving people the illusion of smoothness. After washing, it will reveal its original shape, which is common in the pre-shrinkage of Lyocell fabric. Burning is to burn off the hairiness on the cloth surface at high temperature, which is subject to the temperature of the burning machine and the inverted state of hairiness on the cloth surface, and cannot be completely smooth. mercerizing not only has the effect of removing long hairiness on cloth surface, but also can produce internal collapse effect of ring spinning yarn, the yarn becomes more compact, the cohesion is enhanced, and the problem of linting during use is improved. Enzyme polishing has the best finishing effect, but it will reduce the strength of the fabric and reduce the abrasion resistance and wet friction fastness of the fabric. It is widely used in cylinder dyeing Lyocell fabrics. Adding crosslinking agent in dyeing and post-finishing is also a common method now.
Common smooth dyeing and finishing methods are also suitable for the production of smooth lyocell fabrics.

In actual production, several methods are often used together to make the smooth effect of Lyocell fabric better. In addition to dyeing and finishing, the selection of fully cross-linked, semi-adhesive fibers, longer fibers, the use of Sailuo compact spinning and vortex spinning processes and other measures also help to maintain the smooth state of Lyocell clothing in the subsequent consumer wearing and washing process.
