The performance index of the acrylic scarf thick yarn refers to the number. The number of naps is expressed in metric count. If the count is large, the wool is fine. The count is small, the wool is thick. Metric count refers
to how many kilometers does 1kg wool have, that is how many yarns. Such as 1 kg wool is 18000m long,that is there are 18 yarns.
The twist of the roving of the acrylic scarf thick yarn is the twisting number per unit length. The number of pile yarns is different and the twist is different. In order to compare the twist of different count wool yarn and pile yarn, the concept of " twist factor" is commonly used. ". When choosing the “twist factor”, generally pure wool is greater than the blended yarn, blended yarn is greater than chemical fiber yarn. Higher undercoat content is than a greater than the lower undercoat content, and finer yarn count is greater than coarse yarn count.
The strength and elongation of the acrylic scarf thick yarn
The tensile strength of the acrylic scarf thick yarn is known as strength, expressed as the load of the broken yarn. The length of the yarn and pile that is stretched is called elongation. The strength of the yarn and pile is closely related to the fastness and production efficiency of the fabric. Strength is the basis of the fabric strength and elongation.
The strength and elongation of the acrylic scarf thick yarn is an important index of quality. Because the strength and elongation directly affect the quality, it is necessary to appropriate strength and elongation. Too much raw material will make the wool yarn and yarn relaxation, strength is reduced. The strength is too small, the strength is increased, and the wool yarn and the wool become stiff. The strength and elongation of the yarn and the pile are different from the degree of use and processing and the arrangement of the fibers. The quality of raw materials is good, the fiber arrangement is neat, twisting and appropriate, the higher the strength of the plush yarn, the better the telescopic performance.
