[0002] Lyocell fiber is a type of renewable cellulose fiber. It is called "green fiber" because it comes from nature, has an environmentally friendly processing process, and is biodegradable after use. Based on the "green and sustainable" characteristics of Lyocell and its good wearing performance, yarns and fabrics made of Lyocell fiber have great market prospects in the textile industry. Fabrics made of Lyocell yarn have a soft and smooth feel, good drape, breathability and wearing comfort. Different pure Lyocell fabrics and blended fabrics can be produced using different weaving processes, which are often used in the design and manufacture of various types of clothing, including underwear, casual wear, formal wear, and even outdoor equipment.

[0003] However, Lyocell fibers will fibrillate under wet friction, which will affect the fiber properties and further affect the yarn and fabric made from it. Therefore, the measurement of the fibrillation degree of Lyocell is an important indicator.
