About the fineness index of the yarn

1. Inch count (Ne) - a multiple of 840 yards of a 1 pound weight yarn at a specified moisture regain, which means that 1 pound of yarn is exactly 840 yards long, 1 yarn, 1 pound weight. The length of the thread is 21 × 840 yards long, and the fineness of the yarn is 21, written as 21s. The inch count is a fixed weight system, so the larger the count, the finer the yarn. The British system is not a statutory yarn fineness index in China, but it is still widely used in enterprises, especially the cotton textile industry.

2, metric count (Nm) - in the public regain rate, 1 gram weight of the yarn length of the multiple, that is to say 1 gram of heavy yarn is exactly 1 meter long, is 1 (male) yarn, 1 gram weight The yarn length is 200 meters long and the yarn has a fineness of 200 pieces. The metric count is also a fixed weight system, so the larger the count, the finer the yarn. Cotton textile wool textile industry has been used.

3, Tex (Tex) number - also known as "number", refers to the weight of 1000 meters long yarn at the specified moisture regain rate, it is a fixed length system, the greater the weight, the thicker the yarn , commonly used to represent wool yarn.

4, fineness (D) - also known as "denier" or (denier: denier), refers to the weight of the 9000 meters of yarn or fiber in the specified moisture regain, it is also fixed length system Unit, the greater the weight, the thicker the yarn or fiber, which is often used to represent chemical fiber filaments, silk, and the like. Due to the irregular shape of the filaments and the yarn, and the hairiness (extended fiber short hair) on the surface of the yarn, we cannot express the fineness by the diameter, so the textile worker uses the above indicators. Yarn fineness index calculation formula and conversion relationship Ne = yarn length code number / (840 * yarn weight pounds) Nm = fiber or yarn length meters / weight grams Ntex = (1000 * fiber or yarn weight Gram number / length meter Nden = (9000 * fiber or yarn weight grams) / length meter conversion relationship: Nm = 9000 / Nden Ntex = 1000 / Nm Ntex = Nden / 9 Ntex = 583 / Ne (cotton type Material); Ntex=590.5/Ne (chemical fiber)
