(A) yarn by spinning process points
A yarn that has been routed through a combing process. It is compared with the carding yarn, the material is better, the fiber in the yarn straight parallel, excellent yarn quality, fine fineness of the yarn.
A yarn that has been spun through a general spinning process. Also called carded yarn, cotton and wool slightly different.
(B) according to the composition of the yarn length of fiber points
Filament yarn: one or more continuous filaments that are joined together, twisted or deformed to form yarns.
Short fiber yarn: short fiber twisted into a certain fineness of the yarn, can be divided into three kinds.
Cotton yarn: from raw cotton or cotton fiber in the cotton spinning equipment or pure spinning or processing made of yarn.
Medium-length fiber yarn: from the long fiber in the cotton or special equipment from the processing of the yarn.
A yarn made from pure or blended wool or wool fibers on woolen equipment.
Filament short fiber composite yarn: from short fibers and filaments using special methods of spinning yarn, such as core yarn, wrapped yarn and so on.
(C) according to the composition of the fiber type of yarn points
Pure spinning: Spinning with a fiber is called pure spinning. Named when the "pure" and fiber name, such as pure polyester yarn, cotton yarn and so on.
Blended yarn: A yarn that is spun with two or more fibers. Blended yarn naming rules: raw material blending ratio is different, the proportion of the former; the same proportion, according to the natural fiber, synthetic fiber, recycled fiber in order. When writing, the proportion of raw materials and fiber type together to write, raw materials, the ratio between the semicolon "/" separated. Such as polyester / cotton (65/35) yarn, wool / nitrile (50/50) yarn, polyester / sticky (50/50) yarn.
A yarn made of two or more different fibers or twisted yarns of different colors.
Mixed yarn: the use of two filaments and the combination of yarn, in order to improve the performance of certain aspects.
(D) the yarn by dyeing and finishing processing points
A yarn that retains the original color of the fiber without any finishing.
Bleached yarn: bleached, the color of the white yarn. Usually refers to the cotton yarn and hemp yarn.
Dyed yarn: Dyed, with a variety of colors of yarn.
Color spinning: yarn made of colored fibers.
Burning yarn: the singeing process, the surface of the more smooth yarn.
Mercerized yarn: mercerized yarn, mercerized cotton yarn, mercerized yarn. Mercerized cotton yarn is yarn in a certain concentration of lye treatment to make the yarn has a silk general luster and high strength; mercerized yarn is the yarn in the fiber to remove the scales, so that the yarn soft, and the skin is too stimulating.
(5) yarn according to the yarn line density points
Cotton yarn according to the thickness is divided into coarse (No.) yarn, the special (No.) yarn, fine hold (No.) yarn and special holding (No.) yarn.
The coarse yarn is a yarn having a linear density of 32 te /
In particular yarns are yarns with a linear density of 31-21tex.
Fine yarn: refers to the yarn density of 11-20tex or more yarn,
Extra special yarn: refers to the yarn density of 10tex or less.
(6) according to the structure of the yarn shape points
Yarns are made of textile fibers, with a certain mechanical properties, fineness and softness of the continuous strip.
The so-called "yarn", in fact, "yarn" and "line" collectively, generally defined as: yarn is a variety of textile fibers as raw materials made of continuous linear objects, it is thin and soft, and has to adapt The basic performance required for textile processing and final product use. In the textile also often "yarn" and "line" separately defined, that is, "yarn" is a lot of short fibers or filaments arranged in a nearly line state, and along the axial rotation twist, composed of a certain strength and line Density of the product, and "line" is by two or more than two single yarn twist together from the product is called the line or strand.
Yarn according to different classification basis, can be divided into different types, according to the structure of the yarn shape can be divided into 10 kinds of yarn.
Monofilament: refers to a long length of continuous single wire.
Multifilament: refers to two or more monofilaments together with the tow.
A twisted yarn formed by twisting.
Composite twist: twist through - times or multiple concatenation, twisted into a composite twist.
Deformation of silk: chemical fiber raw silk deformation through the processing to have a curl, spiral, ring and other appearance characteristics. The purpose of processing is to increase the porosity and flexibility of the staff. According to the performance characteristics of the seizure, usually there are elastic silk, yarn and three kinds of silk.
A single continuous strip made of spun fibers by spinning.
Strand: Two or more single yarns are formed by twisting. If formed by the merger of two single yarn, known as the double strand, three or more is called multi-strand. The strand is re-twisted to become a twist strand.
Fancy yarn: made with a special process, with a special appearance of the shape and color of the yarn, including the color line and floral lines. Is composed of core yarn, yarn and yarn in the twist on the color twist machine formed on the surface with a fiber knot, bamboo, ring, braids, spiral, wave and other special appearance or color.
Bulk yarn: Expanded yarn is a full-bodied yarn with high softness, which is processed by heat-shrinkable (thermoplastic) processing of polypropylene fiber. The low shrinkage performance and high shrinkage performance of the polyester fiber in a certain proportion of the mixture made of yarn, and then relaxation heat setting. In this way, the high shrinkage fiber shrinks large, forming the core, the low shrinkage fiber shrinks small, is squeezed on the surface to form the arc, thereby making fluffy yarn.
Core yarn: is the filament or short fiber yarn as the core, the outsourcing of other fibers or yarn and the formation of yarn.
