Physical indicators of wool mainly include fineness, length, bending, strength and elongation, elasticity, felting, moisture absorption, color, and luster

Wool shearing

Fineness is an important process characteristic that determines the quality and value of wool fibers, expressed in micrometers of fiber diameter or quality count; The smaller the fineness, the higher the count, and the finer the spun yarn. The length includes natural length and straight length, the former refers to the linear distance between the ends of the hair bundle, and the latter is the length measured by straightening the fiber. The elongation rate of fine hair is above 20%, and that of semi fine hair is about 10-20%. Under the same fineness, the longer the wool, the higher the spinning performance, and the better the quality of the finished product. Bending is widely used as a basis for evaluating the quality of wool. Wool with neat and consistent bending shapes, spun yarn and products have a soft feel, good elasticity, and warmth retention. Fine hair has a large number of bends and a high density, while coarse hair appears wavy or flat without bends. The strength and elongation have a direct impact on the firmness of the finished product. Strength refers to the stress of wool on fracture; Elongation refers to the increase in length due to the action of fracture force. There are significant differences in the breaking strength of various types of wool. The fineness of the same type of hair is directly proportional to its absolute strength, and the thicker the hair, the greater its strength. The more developed the medulla with medullary hair, the poorer its ability to resist breakage. The elongation of wool can generally reach 20-50%. Elasticity can maintain the original form of the product, which is an indispensable characteristic of carpets and blankets. Wool generally has excellent felting and moisture absorption properties. Gloss is often related to the scale coverage state on the surface of fibers, and fine hairs have weaker ability to reflect light, resulting in a softer luster; The luster of coarse fur is strong and shiny. Weak luster is often caused by damage to the scale layer

Processing Procedure

Before spinning raw wool, it needs to be preliminarily processed into washed wool. During processing, the wool is first selected to make the quality of the wool more uniform, and then the wool is fluffy by opening the wool and beating the soil to improve the washing effect. Then wash the wool to form a stable emulsion of lanolin, while impurities float in the washing solution. After treatment, wet wool with about 40% water content can be obtained, which is then dried. In production, multiple combined machines are used to continuously operate once to obtain washed wool, and then enter the top manufacturing process; The wool sliver is drawn and refined on the spinning machine before entering the textile process
