Textile gods don't know? Four Core Questions of Yarn Yarn Number

Speaking of the word "count", many babies in the cotton yarn industry rushed to be extremely friendly. But when it comes to the unpredictable situation, even the industry gods may shake their heads. Don't panic, we've sorted out the most complete cotton yarn count guide in history for you, you don't know and you should know, all here! Ordinary people I don't tell him.
I. What is the ghost of the number of branches?
We use rice to calculate length, weight to calculate kilograms, and count cotton yarn roughness to calculate count count. Say something reasonable. Number of count (S) is the unit of cotton yarn thickness. For example, chestnuts, a quantity of cotton arbitrarily elongated into different lengths, shorter natural thicker, longer natural thinner, then they use different branches.
The main count of cotton yarn is 10S, 18S, 21S, 32S, 42S, etc. (from left to right & mdash; & mdash; getting thinner and thinner)
The higher the count, the thinner the yarn. Think of the chestnuts on the top. The same cotton bunch pulls longer and naturally thinner.
2. Yarn Family
So according to different count, the yarn family is divided and divided again!
Spinning yarn: 28 & le; count & le; 262. This kind of yarn is suitable for high-grade fine fabrics, such as high-count shirts, worsted sweaters, etc.
Medium count yarn: 18 & le; count & le; 27. Used for weaving plain cloth, twill cloth and other general fabrics.
Roving: & nbsp; 8 & le; count & le; 17 & nbsp;. Suitable for users of thick fabrics, such as tweed, plain cloth, etc.
3. Various Expressions of Branches
Representation of single yarn: 32 single yarns & mdash; & mdash; 32S
Representation of strand: 32 twists and 2 twists & mdash; & mdash; 32S/2; 42 twists and 3 twists & mdash; & mdash; 42S/3;
According to the difference between the fixed weight system and the fixed length system, the number of branches has different manifestations. It can be seen that except D as a unit, the other three representations are the bigger the value, the thinner the yarn. Is this more clear?
Tex (Tex): Weight grams of 1000-meter yarn. The bigger the TEX, the thicker the yarn.
Writing method: Number (plus unit) X shares. Such as: 21texX2
2. N (metric count): the number of metres in length of heavy fibers or yarns per gram (1g). The bigger the N, the thinner the yarn.
Writing Method: Number/Unit. Such as: 32/3
3. S (British count): Each pound (0.4536kg) of fibre or yarn is 840 yards in length for one mile. The bigger the S, the thinner the yarn.
Writing method: Number S/Unit. Such as 32S/3
4. D (Daniel): The weight grams of 9000 meters long fibers. The bigger the D, the thicker the fiber.
Fourth, one-key conversion of multiple units
As the saying goes, it's easy to be confused when there are more people, and it's easy to involve all kinds of conversion problems when there are more units. However, the intimate cotton yarn ring has already been sorted out for you, and you can't be afraid to find it anywhere.
