Classic yarn strength and elongation
The tensile strength of the classic yarn is said to be strong. The length of the yarn is expressed by the load of the classic yarn, and the length of the yarn and the yarn is elongated.
The strength of the classic yarn is closely related to the fastness and the production efficiency of the fabric. The strength is the basis of the tensile strength of the fabric. Therefore, the elongation of the whole yarn and the wool yarn is an important index of quality, and the tensile strength directly affects its quality , The requirements must be appropriate strength and extension, too large to make loose yarn and loose yarn, strong reduction; strong elongation is too small, strong increase in the yarn and cashmere become stiff. Wool yarn and wool yarn and the strength of the use of raw materials and the degree of processing, as well as the fiber arrangement of different circumstances, good quality raw materials, fiber arrangement neatly, twisted and appropriate wool yarn line of the higher strength, stretch performance will be good The
The twist of the classic yarn is the number of twists in the unit length. Twist twist, "S" twist and "Z" twist, twist generally refers to the number of twist / m, wool yarn line count is different, twist is not the same, in order to facilitate the comparison of different count yarn and yarn twist, Twist factor "concept. "Twist coefficient" choice, the general pure wool is greater than the blended yarn, blended yarn is greater than the chemical fiber yarn, short hair content is higher than the short hair content is low, the yarn is thinner than the yarn branch rough.
