(I) Yarn According to 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 is spun from a normal spinning process. Also called carded yarn, cotton and wool are slightly different.
(b) According to the fiber length of the constituent yarns
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.
(c) According to the fiber types of the constituent yarns
Pure spinning: A fiber spun yarn is called pure spinning. Named "pure" and fiber names, such as pure polyester yarns, pure cotton yarns, etc.; blended yarns: yarns that are blended with two or more fibers. The nomenclature of blended yarns is: when the proportion of raw materials blended is different, the proportion is larger; when the ratio is 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.
(D) Yarn according to 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 yarn: dyed and processed, with various colors of yarn. Colored spinning: Yarn spun from colored fibers. Singeing yarn: Yarn with smooth surface after singeing. Silk yarn: Mercerized yarns, mercerized cotton yarn, mercerized wool yarn. Mercerized cotton yarns are yarns treated in a certain concentration of lye to give the yarns a silky general luster and a higher strength; mercerizing yarns remove the fibers of the wool yarns, making the yarns soft and too irritating to the skin.
(five) Yarn is divided into 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: Yarn with a linear density of 11~20tex. Extra Fine Yarn: Yarn with a linear density of 10tex or less.
(f) According to the structure of the yarn
Yarn is a continuous strip of mechanical properties, fineness, and softness that consists of textile fibers.
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.
Yarn can be divided into different types according to different classification basis. According to the structure of the yarn can be roughly divided into 10 types of yarn.
Monofilament: refers to a long continuous single yarn: refers to a bundle of two or more monofilaments that are joined together. Filament: Yarn formed by multifilament twisting. Composite twisted silk: After the twisted silk has been combined one or more times and twisted, the composite silk yarn is transformed into a textured yarn: the chemical fiber precursor yarn is subjected to deformation processing to give it appearance characteristics such as curl, spiral and loop. The purpose of processing is to increase the bulkiness and elasticity of the craftsman. According to the performance characteristics of the deduction, there are usually three kinds of elastic yarns, bulked yarns and network yarns. Single yarn: A single continuous strand formed by spinning staple fibers: Two or more single yarns are combined and twisted. If two single yarns are combined, they are called double strands, and three or more strands are called multiple strands. The stocks will be combined again and again to become rehabilitative strands. Fancy yarn: A yarn made with a special process that has a special appearance and color, including a flower line and a floral line. It is formed by twisting the core yarn, gauze and solid yarn on the color twister. The surface has special appearance shapes or colors such as fiber knots, bamboo knots, loops, braids, spirals and waves. Bulked yarns: Bulked yarns are full-bodied yarns that are processed with the heat shrinkability (thermoplasticity) of polyester fibers and have a high degree of softness. Low-shrinkage and high-shrinkage polyester fibers are mixed at a certain ratio to make yarns, which are then relaxed by heat setting. In this way, the high-shrinkage fiber shrinks to form a yarn core, the shrinkage of the low-shrinkage fiber is small, and the arc is formed by being pressed on the surface, thereby producing a fluffy yarn. Core-spun yarn: Yarn formed by filaments or staple yarns as a yarn core and out of other fibers or yarns.
