Basic knowledge of textile yarn

Method of calculation of textile yarn

1. Units

(1), fixed length system:

A. Tex: The number of quality grams for a textile yarn of 1000 meters in length at a predetermined return rate is called a special number.

Common: Ntex =(G/L) × 1000

In the formula: G is the weight of the textile yarn(g), L is the length of the yarn(M)

B. Dannier: The number of grams of mass of 9,000 meters of textile yarn at a predetermined return rate is called the number of digits.

Common: Nden =(G/L) × 9000

In the formula: G is the weight of the yarn(g), L is the length of the yarn(M)

(2) Definitive system:

A. Public branch number(public branch): 1 gram of textile yarn(silk) has a length of meters.

Common: Nm = L/G

In the formula: 1 is the length(M) of the textile yarn(silk), and G is the weight(g) of the textile yarn(silk)

B. English number(English number): The number of 840 yards of length that a pound of textile yarn has.

Common: Ne =(L/G) × 840

In the formula: L is the length(code) of the textile yarn(silk) and G is the weight(pound) of the textile yarn(silk).

2, Unit conversion

A. Special number Ntex and British branch Ne

Ne = C/Ntex(C is a constant, chemical fiber is 590.5, cotton fiber is 583, if it is mixed textile yarn can be calculated based on mixing ratio, Such as: T/JC(65/35) 45S yarn C = 590.5 * 65 % + 583 * 35 % = 588, and then calculated by formula)

B. British branches Ne and metric branches Nm

Pure chemical fiber: Ne = 0.5905 N M Pure cotton: Ne = 0.583N M

Mixed textile yarn: such as T/JC(65/35) 45S Ne =(0.5905 * 65 % + 0.583 * 35 %) Nm

3, special number Ntex and metric Nm

Ntex × Nm = 1000

4, special number Ntex and number Nden

Nden = 9 * Ntex

Second, twist degree and twist coefficient of textile yarn

1. Twisting: the number of twists per unit length of textile yarn. The Ttex(number) twist of cotton textile yarn and cotton-type chemical fiber textile yarn is represented by the number of twirls in the length of the textile yarn 10cm; The imperial branch number system, Te, is represented by an inch number of turns. The twist Tm of worsted textile yarn and chemical fiber filament is expressed in terms of the number of twists per meter. The relationship between the above methods is:

Ttex = 3.937 Te = Nm/10 Te = 0.254 Ttex = 0.0254 Tm

The twist is divided into Z and S. After the fibers in the textile yarns in the yarns are twisted, the direction from the bottom up and from right to left is called S <UNK>; From the bottom up, from left to right is called Z <UNK>.

The expression of the twist of the stock yarn thread, the first letter represents the twist direction of the single textile yarn, and the second letter represents the twist direction of the stock yarn thread. After two twisted stock yarn threads, the first letter represents the twist of the single textile yarn, the second letter represents the initial twist, and the third letter represents the double twist. For example, the single textile yarn is Z twist and the first twist is S twist. For the Z twist stock yarn thread, the twist is represented by ZSZ.

2. Twisting coefficient

Special number twist coefficient αtex = Ttex * Ntext 1/2

British twist coefficient αe = Te/Ne1/2

Metric coefficient αm = Tm/Nm 1/2

The relationship between the special number twist coefficient αtex and the imperial twist coefficient αe is:

αtex = Ttex * Ntext 1/2 = Te/2 .54 * 10 * 5831/2 * Ne1/2(583 is the coefficient of pure cotton varieties, if it is blended, fiber yarn, please refer to the special number and the English conversion constant C change)

Third, strength of yarn and breaking strength of single textile yarn

Single textile yarn strength: the force required to break a single textile yarn, called single textile yarn strength or single textile yarn strength, in cattle(N), Cniu(CN).

Single textile yarn fracture strength: The ratio of single textile yarn strength P to textile yarn special number Ntex is Km or cN/tex

Standard Yarn Weight

The weight of a textile material at a set moisture rate or a set moisture content is called "standard weight"

The relationship between the standard weight of textile materials and the nominal weight at the actual moisture return rate is:

Textile yarn standard weight = weight *(100 + metric return rate) /(100 + actual return rate)

Calculation of standard weight in production. The material is often dried first and calculated according to the drying weight. The formula is as follows:

Standard weight = dry weight of material(100 + metric return rate) / 100

textile yarn is a continuous linear material made of various textile fibers. It is fine and soft and has the basic properties required for textile processing and final product use. Yarns are mainly used for weaving shuttle fabrics, knitted fabrics, knitted fabrics, and some non-woven fabrics. A small number of them are directly in the form of linear textiles, such as various sewing lines, plush yarn threads, embroidery yarn threads, ropes, and other miscellaneous yarn threads.

Textile yarns by raw material type:

First, pure textile yarn

Pure textile yarn consists of the same kind of fiber, such as pure cotton textile yarn, wool textile yarn, sticky fiber textile yarn, acrylic textile yarn, polyester textile yarn, nylon textile yarn and so on.

Blended(mixed) textile yarn

Mixture or intertwined textile yarn is a yarn consisting of two or more fibers, such as polyester / cotton, wool / polyester, wool / nitrile, polyester / visco/nitrile, silk yarn / cotton, etc.. Short fiber textile yarn with more than two kinds of short fibers, called mixed textile yarn; A textile yarn made of more than two kinds of long textile silk yarns(such as twisted yarns) is called a blended textile yarns. Its blending ratio is as follows:

Xa = Wa/W * 100 % of which Xa is the content of some component fiber

Wa is the weight of the component fiber

W is the weight of the blended textile yarn

According to the physical properties and characteristics of the textile yarn, it can be divided into seven series.

Series 1. Short fiber textile yarn

Short fiber textile yarns are yarns made from various kinds of short fiber by spinning technology. Usually, the short fiber is first spun into a single textile yarn by the short fiber textile yarn system, and then a few single textile yarns are merged and twisted to form a stock yarn thread. If several stock yarn threads are further combined and combined, it becomes a compound stock yarn thread. The stock yarn thread is used much more in woolen fabrics. Which form of single textile yarn, stock yarn thread and double twist stock yarn thread is used in the fabric shall be determined according to the design requirements and usage characteristics of the fabric.

Series 2. Continuous silk yarn(filament or silk)

1, Textile silk yarn

Using cocoon silk yarn on silkworm cocoon as raw material, the continuous filament obtained by multiple cocoon silk composite clusters is called cocoon silk textile yarn because it contains silk yarn gel, commonly known as raw silk yarn, and factory silk yarn. Several filaments are combined and twisted to form a silk thread, which contains glue and degumming. Silk filament yarn is an important raw material in silk yarn industry and is mainly used for processing various silk yarn fabrics.

2, Chemical fiber textile silk yarn

Chemical fiber textile yarns are clustered into yarns at the same time as the fibers are formed. They do not need to be assembled into yarns by the short fiber spinning process as chemical short fibers, and then woven into various types of fabrics. Compared with each other, the former has a high production efficiency. And although it is made of the same kind of fiber, the long silk textile yarn and the short fiber textile yarn are very different in style.

Fiber forming polymers form continuous filaments through a wire jet board. The number of fibers contained in the wire strips depends on the number of filaments on the thread jet board. The single-hole yarn thread jet board emits a single hole long silk textile yarn(commonly known as glass thread)., that is, single Kongsi, It can be used for weaving transparent fabrics. A long silk textile yarn made of a porous wire jet head, called a double silk textile yarn, referred to as a double yarn thread. After the filamentous textile yarn is twisted, there is a long silk textile yarn, and a few long silk textile yarns are merged and twisted to form a stock yarn thread. Because the strand is composed of filaments, it is also called a silk textile yarn thread.

Series 3, stock line

The textile yarn formed by the accumulation of two or more single textile yarns, which are combined with two or more textile yarns, is called a stock thread, referred to as a thread. If necessary, multiple strands can also be gathered again by merging and twisting into another textile yarn. Such yarn is called a double-twisted strand. The single textile yarn used to form the stock thread can be either a short fiber textile yarn or a long silk textile yarn; It can be the same fiber raw material, can also be different fiber raw materials, can be the same as short fiber textile yarn, can also be different.

Series 4. File/fiber composite textile yarn made of a combination of short fiber and long silk textile yarn

Cluster by short fiber and silk textile yarn.
