Yarn Classification

Yarn classification

1 according to the spinning process

Combed yarn: Yarn spun after combing process. Compared with the carded yarn, the material is better, the fibers in the yarn are straight and parallel, the yarn quality is excellent, and the fineness of the yarn is fine.

Carded yarn: The yarn spun from a normal spinning process becomes a coarse yarn, also known as a carded yarn. Cotton and wool are slightly different.

Discarded yarns: Worsted yarns are made from poor quality raw yarns that are spun from coarser yarns. Usually the yarn is thicker and has more impurities.

2 According to the composition of the fiber length

Filament Yarn: Yarn formed by one or more continuous filaments that have been joined, twisted, or deformed.

Short fiber yarns: Short fibers are twisted into yarns with a certain degree of fineness, which can be divided into three types.

(1) Cotton Yarn: Yarn produced by pure spinning or blending raw cotton or cotton fibers on cotton spinning equipment.

(2) Medium and long fiber type yarns: They are made of medium and long fibers processed on cotton spinning or special equipment, with - yarns.

(3) Wool Yarn: A yarn obtained by pure spinning or blending of wool fibers or wool fibers on wool spinning equipment.

Filament staple fiber combination yarns: yarns spun from staple fibers and filaments using special methods, such as core-spun yarns and wrapped yarns.

3 According to the composition of the fibers of the yarn

Pure spinning: Yarn spun from a fiber is called pure spinning. Named "pure" and fiber names, such as pure polyester yarn, pure cotton yarn, etc.

Blended yarn: A yarn that is blended with two or more fibers. The nomenclature of blended yarns is: when the blend ratio of raw materials is different, the proportion is larger; when the proportions are the same, the order of natural fibers, synthetic fibers, and recycled fibers is arranged in order. When writing, write the raw material proportion together with the fiber type. The raw materials and proportions are separated by a semicolon "/". Such as polyester/cotton (65/35) yarn, wool/nitrile (50/50) yarn, polyester/viscose (50/50) yarn, etc.

Cross yarn: Yarn made up of two or more different fibers or single yarns of different colors.

Blended Yarn: Yarn made by combining two types of filaments to improve certain properties.

4 yarn dyeing and finishing processing

Primary yarn: Yarn that retains the original color of the fiber without any dyeing and finishing.

Bleached yarn: bleached, whiter yarn. Usually refers to cotton yarn and hemp yarn.

Dyed yarns: dyed and processed with yarns of various colors.

Colored spinning: Yarn spun from colored fibers.

Singeing Yarn: Satin-burned yarns with a smooth surface.

Silk yarn: Mercerized yarns, mercerized cotton yarn, mercerized wool yarn. Mercerized cotton yarn is a yarn treated in a certain concentration of lye to give the yarn a silky general gloss and high strength; mercerized wool yarn removes the scales of the fibers in the wool yarn, making the yarn soft and irritating to the skin.

5 Yarn divided by yarn line density

Cotton yarns are subdivided into coarse yarns, middle yarns, fine yarns, and ultrafine yarns.

Coarse yarn: refers to a yarn with a linear density of 32 tex or more.

Special yarn: refers to yarn with a thread density of 31-21tex.

Fine yarn: refers to a yarn with a linear density of 11~20tex or more.

Extra Fine Yarn: Yarn with a linear density of 10tex or less.

6 according to the structural shape of the yarn

Yarn is a continuous strip that consists of textile fibers and has certain mechanical properties, fineness and softness.

The so-called "yarn" is actually a general term for "yarn" and "thread". It is generally defined as: yarn is a continuous, linear object made of various textile fibers. It is thin, flexible, and has an adaptability. The basic properties required for textile processing and final product use. In textiles, it is also common to define "yarn" and "thread" separately. That is, "yarn" arranges many short fibers or filaments into a near-appearance state and is twisted along an axial direction to form a layer with a certain strength and strength. Density products, while "threads" are products made by combining two or more single yarns, they are called strands or strands.

Our product is a device that weaves yarn into webbing, such as cotton lace making machine,fabric weaving machine,jacquard needle loom machines.
