What is the concept of fiber density Explanation of fibers What is the interpretation of fibers

You're talking about line density.

Line density—mass per unit length. The thread density can be obtained by dividing the mass of the fiber or yarn by its length. The linear density of a fiber refers to the thickness of the fiber.

Linear density is one of the most important physical properties and geometric characteristics of fibers, which not only affects textile processing and product quality, but also is closely related to the performance of fabrics. Similarly, thread density is also the most important indicator of yarn. The thread density of yarn affects the physical and mechanical properties, feel, style, etc. of textiles, and it is also one of the important bases for fabric design.

The density of fibers and yarns can be expressed in a variety of ways, and is generally expressed as an indirect indicator proportional to the cross-sectional area of the yarn. Commonly used indicators are Tex (number), metric count, imperial count, denier, etc. In general, the linear density index of fiber and yarn is mainly divided into two categories: fixed-length system and fixed-weight system.

Fixed-length system The fixed-length system refers to the weight of a certain length of fiber or yarn, and the higher its value, the thicker the fiber or yarn. At present, the commonly used ones are tex (tex), decitex (dtex), millitex (mtex), denier (d) and so on. The legal unit of measurement in China is the special number system.

Tex is referred to as "Tex", which refers to the weight grams of a 1000-meter-long fiber or yarn at a fixed moisture regain rate. Tex is commonly known as the number of cotton yarns.

In addition, the diameter can also be used to indicate the thread density of the yarn. The diameter of the yarn is an important basis for the design of the fabric and the formulation of manufacturing process parameters, which can be measured under the microscope, but in actual production, the diameter of the yarn is converted by the number of features or threads of the yarn and the density of the yarn.

In the linear density representation of strands, the special number system is expressed by multiplying the number of single yarns that make up the strands, such as 14 2. When the special number of single yarns in the strand is different, it is expressed by adding the special number of single yarns, such as 16+18. The count system is expressed by dividing the number of threads of a single yarn that makes up the strands by the number of strands, such as 50 2.

If the number of single yarns that make up the strands is different, the number of single yarns should be juxtaposed and separated by diagonal lines, such as 24 48.

The density of multifilament threads of chemical fibers is expressed by the number of monofilaments and the total number of Texes that make up the multifilament. For example: TEX 30 F, which means that the bus density of the multifilament is Tex, and the number of monofilaments is 30.

The density of the multifilament threads of a chemical fiber or silk is the sum of the densities of the monofilaments that make up the multifilament.

Fiber density refers to the degree of compactness of fiber in a certain unit area.

Fiber (Biological & Chemical Concept) Fiber (Fiber; Fibre) refers to a substance consisting of continuous or discontinuous filaments.

In plants and animals, fiber plays an important role in maintaining tissues. Fiber is widely used, can be woven into fine thread, thread and hemp rope, and can also be woven into a fiber layer when making paper or weaving felt; At the same time, it is also commonly used to make other materials, and to form composite materials together with other materials.

The filtration accuracy of the fiber has a lot to do with the thickness of the fiber. The fineness of the fiber is the titer. There are four units of fiber thickness:

1) Denier: The weight grams of a 9,000-meter-long fiber at a given moisture regain rate.

Denier is referred to as denier (d), such as 9000 meters of fiber weighs 1 gram for 1 denier, when the density of the fiber is constant, the larger the denier number, the thicker the fiber. It is commonly used to represent chemical fiber filament, silk, etc. Although not a metric unit, a denier is the most commonly used.

Writing method: number (plus unit) x number of strands e.g. 21dx2.

Due to the irregular shape of the fiber filament and the yarn, and the hairiness (short hairs of the fiber sticking out) on the surface of the yarn, the diameter is rarely used to express the degree of the book, and the denier or the following units are mostly used. The thickness of natural silk or chemical fibers is expressed by the weight of a certain length of fiber, the finer the fiber, the smaller the tire.

2) Tex (Tex): The weight grams of a yarn with a length of 1000 meters at a nominal moisture regain rate. The larger the Tex, the thicker the yarn.

Turks are metric units. Since d, denier and decinator are similar. Therefore, DTEX is also more commonly used.

Writing method: number (plus units) x number of strands e.g. 21texx2

3) Metric count (n): the number of meters of length per gram of heavy fiber or yarn at a nominal moisture regain rate. The larger the metric count, the finer the yarn. Writing method key posture training: number number of strands such as: 32 3

4) Imperial count (s): At the nominal moisture regain rate, each pound (weight of fiber or yarn length of 840 yards is one count. The larger the count, the finer the yarn. Writing method: Number s number of strands such as 32s 3

Formula for calculating between units:

Feature Vickers 10= detex --tex 10= dtex )

Denier Turks --d ).

Denier Denitre --d )

Denier Eng = 5315 ---d s = 5315 )

Denier male branch = 9000 --d n = 9000 )

Denier. xiān dù

Denier (d) - also known as "denier" or (denier: denier), refers to the number of grams of yarn or fiber under the official moisture regain rate, 9000 meters of yarn or fiber, it is also a fixed-length unit, gram weight.

The larger the yarn or fiber, the thicker it is, and it is often used to represent chemical fiber filament and silk.

Wait. Due to the irregular shape of the filament and yarn and the hairiness (short hairs of the fiber) on the surface of the yarn, we cannot express its fineness in terms of diameter, so the weaver uses the above indicators.

size;fibre number] The thickness of natural silk or chemical fiber, the weight of a certain length of fiber is used to indicate that the finer the fiber, the smaller the titer.
