Cotton yarn is the main intermediate product in the textile industry and the upstream raw material for printing and dyeing, dyeing, knitting, apparel and other industries. It has a wide range of uses and can be used as knitting yarn, weaving yarn, tatting yarn, and high-speed sewing thread and embroidery thread. The raw materials from which the product is made. 1. Introduction to count Yarn is woven from fibers with a certain strength and fineness, and can be processed into materials of any length. It is the basic unit of fabrics. The thickness of cotton yarn is expressed by count. The count is the length of the veil per unit weight. The specific expression method is represented by S. There are 10S, 18S, 21S, 32S, and 42S. The higher the count, the thinner the veil, and the higher the count. The higher the grade of cotton, the longer the fiber. The “British standard” currently used in China is: one pound (454 grams) of cotton yarn (or other component yarn), when the length is 840 yards (0.9144 yards/meter), the fineness of the yarn is one. If there is one pound of yarn, its length is 10 x 840 yards, its fineness is 10 counts, and so on. The Weibo nickname in front of S is Cotton Yarn Girl. The larger the number, the finer the yarn, and the lighter, thinner and softer the fabric is. The smaller the number, the coarser the yarn, and the heavier, thicker, and rougher the fabric is. 2. The representation method of yarn count. The British symbol is the English letter “S”. The representation method of single yarn is: 32-count single yarn——-represented as: 32S. The representation method of strands is: 32-count. The strand (two strands twisted together) is: 32S/2, and the 42 strands of 3 strands twisted together is: 42S/3. 3. Yarn count calculation method 1. Fixed length system: A. Tex: The mass in grams of a yarn with a length of 1000 meters at a common moisture regain is called the special number. Formula: Ntex=(G/L)×1000 In the formula: G is the weight of the yarn (grams), L is the length of the yarn (meters) B. Denier: the mass in grams of a 9000-meter-long silk at a common moisture regain The number is called denier. Formula: Nden=(G/L)×9000 Where: G is the weight of the silk (grams), L is the length of the silk (meters) 2. Fixed weight system: A. Male count (male count): 1 gram of yarn (Silk) The length in meters. Formula: Nm=L/G In the formula: 1 is the length of the yarn (silk) (meters), G is the weight of the yarn (silk) (grams) B. British count (English count): 1 pound of yarn has Number of 840 code lengths. Formula: Ne=(L/G)×840 Where: L is the length (yards) of the yarn (silk), G is the weight (pounds) of the yarn (silk). 4. The meaning of imported cotton yarn count. The count of cotton yarn refers to the standard for distinguishing the thickness of yarn. The yarn count is the basic unit that makes up the finished fabric. The number of yarn count is inversely proportional to the thickness of the yarn count. The larger the number, the better the yarn count. Thin, general clothing, home textiles, Weibo nickname cotton yarn girl bedding, etc. have relatively high requirements for yarn count. According to the thickness, it is generally divided into 21-count, 32-count, 40-count and the rare 60-count and 80-count cotton yarns, such as: 21 counts: one ounce of cotton can be made into 21 strands of 1 meter yarn, which is 21s cotton yarn; 32 counts: one ounce of cotton can be made into 32 strands of 1 meter yarn, which is 32s cotton yarn; 40 counts: one ounce of cotton yarn can be made 40 pieces of 1 meter yarn, that is 40s cotton yarn; 60 count: one or two cotton yarns can be made into 60 pieces of 1 meter yarn, that is 60s cotton yarn; This means that the higher the count of cotton yarn, the finer the cotton yarn. The finer the cotton yarn, nicknamed the cotton yarn girl on Weibo, the thinner, softer and more comfortable the fabric will be. The requirements for the texture of the raw cotton, the yarn-making technology of the dyeing and weaving factory, and the fabric-making technology of the textile factory will also be The higher it is, so the finer the yarn count, the higher its production cost. Of course, the higher the cotton yarn count, the better. For home textiles and bedding, cotton yarns of 30s-60s are generally suitable. For clothing, cotton yarns of 60s-80s are generally better. 16s-21s are generally used for socks, towels and other fabrics. in production.
