100% Polyester Material and Polyester Ring Spun Yarn 40s2 Raw White

1. Yarn classification according to yarn raw materials

Pure spinning

Pure spinning is made of a kind of fiber material, such as cotton yarn, wool yarn, hemp yarn and silk yarn. This kind of yarn is suitable for making pure textiles.

Blended yarn

Blended yarn is made of two or more kinds of fibers, such as polyester and cotton blended yarn, wool and viscose blended yarn. These yarns are used in fabrics that highlight the advantages of both fibers.

2. Yarn is classified according to yarn thickness

Coarse tex yarn

Coarse tex yarn refers to yarn of 32 tex and above (18 British count and below). This kind of yarn is suitable for thick and thick fabrics, such as tweed and plain cloth.

Medium tex yarn

Medium tex yarn refers to 21-32 t (19-28 British count) yarn. This kind of yarn is suitable for medium and heavy fabrics, such as medium plain cloth, gabardine, khaki, etc.

Fine tex yarn

Fine tex yarn refers to 11-20 t (29-54 British count) yarn. This kind of yarn is suitable for thin and thin fabrics, such as fine cloth, poplin, etc.

Superfine yarn

Superfine yarn refers to yarn of 10 tex and below (58 British count and above). This kind of yarn is suitable for high-grade fine fabrics, such as high count shirt, worsted close fitting sweater, etc.

3. Classification by spinning system

Worsted yarn

Worsted yarn, also known as combed yarn, refers to the yarn spun by combing process, including combed cotton yarn and combed wool yarn. The fiber in the yarn has high parallel straightness, evenness and smoothness, but the cost is high and the yarn count is high. Combed yarn is mainly used as raw materials for advanced fabrics and knitwear, such as spinning, gabardine, tweed, cardigan, etc.

Roving yarn

Roving yarn, also known as carding wool yarn or carding cotton yarn, refers to the yarn combed according to the general spinning system and spun without combing process. There are many short fibers in roving yarn, such as poor parallelism and straightness, loose structure, more hairiness, low count and poor quality. This kind of yarn is mostly used as raw materials for general fabrics and knitwear, such as woolen fabrics, medium and extra high cotton fabrics, etc.

Waste spinning

Waste spinning refers to the yarn made from textile waste (waste cotton) or mixed with low-grade raw materials. Yarn is poor in quality, soft, uneven in evenness, containing many impurities and poor color. It is generally used to weave low-grade fabrics such as coarse cotton blanket, thick pile cloth and packing cloth.

4. Yarn classification according to spinning process

Ring spun yarn

Ring yarn is a kind of yarn which is twisted by traditional spinning method on ring spinning frame. The internal and external winding of fibers in the yarn makes the yarn structure compact and has high strength. However, the production efficiency is limited because the twisting and winding work is completed by a set of mechanism at the same time. This kind of yarn has a wide range of uses, and can be used in all kinds of fabrics, knitting fabrics and ropes.

Free end yarn

Free end yarn refers to the process of condensing and twisting fibers into yarn in the flow field of high-speed spinning cup or in electrostatic field. The twisting and winding of the yarn are completed by different parts, so the efficiency is high and the cost is low.

Roving yarn

Rotor spinning, also known as rotor spinning, is to use the air to condense and twist the fibers in the high-speed spinning cup to produce yarn. Compared with ring spun yarn, the yarn structure is fluffy, wear-resistant, evenness and bright dyeing, but its strength is lower. This kind of yarn is mainly used in plain cloth with bulky and thick texture, pile cloth with good handle and knitted products.

Electrostatic yarn

Electrostatic yarn is a kind of yarn which is made by using electrostatic field to condense and twist the fiber. The structure of the yarn is the same as that of the rotor yarn, and its use is similar to that of the rotor yarn.

Vortex yarn

Vortex yarn is a kind of yarn made by using fixed vortex spinning tube instead of high-speed spinning cup. The yarn has many bending fibers, low strength and poor evenness, but good dyeing and wear resistance. This kind of yarn is mostly used in pile fabrics, such as flannelette, sportswear, etc.

Dust cage yarn

Dust cage yarn, also known as friction spinning, is a kind of yarn made by condensing and twisting fibers with a pair of dust cages. The yarn has layered structure, the core twist is large, the handle is hard, the outer twist is small, and the handle is soft. This kind of yarn is mainly used in industrial textiles, decorative fabrics, and also in outerwear (such as work clothes, protective clothing).

Non free end yarn

Non free end yarn is a new spinning method which is different from free end yarn. In other words, in the process of twisting the fiber, both ends of the fiber strip are held, not the free end. This new type of yarn includes self twist yarn, air jet yarn and core spun yarn.

Self twisting yarn

Self twist yarn is a new type of non free end yarn. It twists two slivers by reciprocating roller. When the slivers are close to each other, they twist and twist each other to form yarn. The twist of this kind of yarn is uneven, and there is no twist section in one yarn, so the yarn strength is low. It is suitable for the production of wool yarn and chemical fiber yarn. It is suitable for fancy and suede fabrics.

Air jet yarn

Air jet yarn is a kind of yarn produced by high-speed jet vortex produced by compressed air, twisting yarn, wrapping and twisting. The yarn structure is unique, the yarn core is almost twistless, the outer fiber is wrapped randomly, the yarn is loose, the handle is rough, and the strength is low. This kind of yarn can be processed into woven and knitted fabrics, and made into men's and women's shirts, sportswear and work clothes.

Core spun yarn

Core spun yarn is a kind of yarn with filament as the core and wrapped with short fiber. It has the advantages of both core filament and short fiber, which makes the yarn performance better than single fiber. The commonly used yarn core filaments are polyester, polyamide and spandex, while cotton, polyester / cotton, acrylic and wool are commonly used for wrapping short fibers. Core spun yarn is mainly used for sewing thread, shirt fabric, burnt out fabric and elastic fabric.

Our pure polyester yarn is spun according to the traditional ring spinning.
