Classification And Characteristics Of Yarns

Yarns are made up of one or more continuous filament or discontinuous short fibers.

Yarn is actually a general term for yarn and yarn.

Yarn is made of raw materials and products, such as sewing thread, knitting thread, embroidery thread, etc.

The structure and properties of yarns directly affect the properties of fabrics and the wearability of clothing, such as the gloss, smoothness, roughness or fuzziness of fabrics, the weight of fabrics, the texture of fabrics, such as fullness, softness, stiffness, elasticity, wear resistance and fuzziness.

Because of the different yarn and processing methods, the yarn has many kinds and different shapes.

his

There are many ways.

According to the raw material of yarn

Pure yarn is made up of a fiber material, such as pure cotton yarn, pure wool, pure silk, pure hemp, purified yarn.

Yarn blended with two or more than two types of yarns.

Such as polyester cotton, polyester hemp, wool viscose yarn.

According to the state of fiber in yarn

Short fiber yarns: yarns twisted by staple fibers.

Usually the 15~100 short fiber is twisted into a single yarn and twisted by 2 or more single yarns.

Short yarns are generally loose and plump. Most sewing threads, knitting yarns and wool are staple fibers.

Filament yarn, which is directly processed by polymer solution, is divided into three types: monofilament, multifilament and composite twisting.

Monofilament is made up of one filament, used for knitting socks, pantyhose, headscarf, swimsuit and so on. The multifilament is made up of several monofilaments, and many silk fabrics are made of multifilament fabrics, such as plain satin and so on. They are used in suits, underwear and so on. Composite twists are twisted by multiple yarns, and different creases are used to weave crepe fabrics according to their uses.

Filament yarn has good strength and evenness and can be made very fine.

It has poor hygroscopicity, easy to take static electricity, smooth and cool handle, and cool.

Silk reeling (Sao): raw silk reeled from cocoons.

Split film wire: polypropylene film, cut or zoned technology to split into the required width, and then stretched into split film wire, used for carpet, pile fabric bottom cloth, woven packaging bags.

According to dyeing and finishing of yarn

Mercerized yarn: cotton yarn is treated with sodium hydroxide and added tension to change the luster strength of yarn.

Singeing yarn: burning the gas or electric heating to burn the yarn surface, and the yarn is more smooth.

Natural yarn: primary yarn, which keeps its original color without bleaching.

Dyed yarn: dyed yarn dyed by raw yarn.

Bleached yarns: yarns made by boiling and bleaching primary yarns.

According to spinning process

Combed cotton yarn and carded yarn.

Combed cotton yarn refers to cotton yarn which is combed and processed on the basis of common carding of the spinning system.

Due to short removal

After several carding, the yarn is parallel and straight. The evenness is smooth, the appearance and performance are better than the combed cotton yarn. It is used for spinning high-grade poplin, sweater and so on.

Combed yarn and carded yarn.

The fibers used for worsted yarns are made of finer, longer and even higher quality wool. They are made of combed wool spinning process. The yarn is parallel and straight, and the yarn is uniform and smooth. It is used for worsted fabrics such as Hua Dane, Valentine and Paris.

Woolen yarns are processed into woollen yarns with a short woolen spinning process. The length of the yarn is uneven, the fibers are not straight enough, the structure is evacuated, and the surface is more hairy. It is used for coats, flannel and carpet.
