Wool-like fiber
Wool-like fiber is the use of chemical fibers to imitate the style characteristics of wool fabrics to produce chemical fiber fabrics, so as to achieve the purpose of replacing wool with chemical fibers.
Performance requirements of wool-like chemical fiber:
1. The tensile properties of wool-like chemical fiber should be similar to that of wool. Some chemical fibers have too large break work and good toughness, but their anti-pilling performance deteriorates. Therefore, the breaking power of wool-like chemical fibers is not as high as possible, and should be controlled within an appropriate range. It is generally believed that the strength and breaking work of wool-like chemical fibers only need to reach the level of wool.
2. Wool-like chemical fibers should have proper crimping properties. By crimping the wool-like fiber, a wool-like curl can be formed, so that the fabric can obtain a fluffy, soft, and elastic hand and style with a strong wool-like feeling.
3. The initial compression modulus of the wool-like chemical fiber assembly should be lower, the compression density should be moderate or higher, and the compression elastic recovery rate should be high, because the compression elasticity and the fabric’s hand feeling, softness, elasticity, and bulkiness, etc. Style is related.
There are two main technical ways for chemical fiber to imitate wool: one is to imitate the morphological structure and performance of wool fiber to develop wool-like fiber; the other is to imitate wool fabric from the appearance, style and performance of the fabric, through spinning, The synergistic effect of spinning, weaving, dyeing and finishing, etc., produces fabrics with woolen fabric style characteristics and performance.
