Introduction to cotton yarn count

Cotton yarn is the main intermediate product in the textile industry. It is the upstream raw material for printing and dyeing, yarn-dyed weaving, 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. Raw materials for making embroidery thread and other products.

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 a single yarn is: 3 2 single yarns——-expressed as: 32S

The strands are expressed as: 32 strands (two strands twisted together) are: 32S/2, 42 strands and 3 strands The combined twist is: 42S/3.

3. Yarn count calculation method 1. Fixed-length system:

A. Tex: The number of grams of mass of a yarn with a length of 1000 meters at a common moisture regain is called the special number. . Formula: Ntex=(G/L)×1000

Where: G is the weight of the yarn (grams), L is the length of the yarn (meters)

B. Denier : The mass in grams of 9,000-meter-long silk at a given moisture regain is called denier. Formula: Nden=(G/L)×9000

In the formula: G is the weight of the silk (grams), L is the length of the silk (meters) 2. Fixed weight production:

A. Male count (male count): the number of meters in length of 1 gram of yarn (silk). 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. Number of British branches (English branches): The number of lengths of 840 yards in 1 pound of yarn. 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 the yarn. The yarn count is the basic unit that makes up the finished fabric. The number of the yarn count is inversely proportional to the thickness of the yarn count. The larger the number, the finer the yarn count. Generally, clothing, home textiles, Weibo nickname cotton yarn girl, bedding and other products have relatively high yarn count requirements, and are generally divided into 21-count, 32-count, 40-count and rarer 60-count and 80-count cotton yarns, such as:

21-count: One or two cotton can be made into 21 1-meter yarns, that is 21s cotton yarn; 32 Count: One tael of cotton can be made into 32 yarns of 1 meter, that is 32s cotton Yarn; 40 counts: One or two cotton yarns can be made into 40 1-meter yarns, which is 40s cotton yarn;

60-count: One or two cotton yarns can be made into 60 1-meter yarns, which is 60s cotton yarn ;

It means that the higher the count of cotton yarn , equal to 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, which will affect the texture of the raw cotton, the technical level of yarn making in the dyeing and weaving factory, and the quality of the fabric produced by the textile factory. The requirements for technical quality are also higher, so the finer the yarn count, the higher the production cost. Of course, the higher the cotton yarn count, the better. For home textiles, bedding, etc., generally 30s-60s cotton yarn is enough. For clothing, 60s-80s cotton yarn is generally better, and 16s-21s is generally used for socks, towels and other fabrics. in production.
