Wool-like fiber: wool-like fiber is to use chemical fiber to imitate the appearance of wool fiber, so as to achieve the purpose of replacing wool with chemical fiber.
1. Performance requirements of wool-like chemical fibers:
1. The tensile properties of wool-like chemical fibers should be similar to those of wool. Some chemical fiber fracture is too large, good toughness, but anti-pilling performance becomes poor. Therefore, the breaking work of wool-like chemical fiber is not the higher the better, but should be controlled in a proper range. Think commonly, the strength of wool - like chemical fiber and fracture work should achieve wool level only can.
2. Wool-like chemical fibers should have appropriate crimp. Through the crimp processing of wool imitation fiber, the crimp similar to wool can be formed, so that the fabric gets fluffy, soft, elastic feel and style, and the wool imitation sense is strong.
3. The initial compression modulus of wool-like chemical fiber assembly should be appropriately low, the compression density should be moderate or high, and the recovery rate of compression elasticity should be high, because the compression elasticity is related to the feel, softness, elasticity, fluffy and other styles of the fabric.
The technical way of chemical fiber hair-like for makeup brush is to develop hair-like fiber by imitating the shape and structure of wool fiber.
