Classification And Characteristics Of Yarn For Textile Fabrics

< p > because of the different fibers and processing methods that constitute "a href=" http://www.91se91.com/news/ "yarn < /a >, there are various kinds and different shapes of yarns.

Its classification methods are also more.

< /p >

< p > (1) the raw material of yarn is divided into < /p >.

< p > 1. pure yarn < /p >

< p > consisting of a fibrous raw material, such as pure cotton yarn, pure wool, pure silk, pure hemp, purified fiber yarn.

< /p >

< p > 2. blended yarn < /p >

< p > yarn made by mixing two or more than two fibers.

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

< /p >

< p > (two) according to the fiber status in the yarn < /p >

< p > 1. short fiber yarn: < /p >

< p > 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.

< /p >

< p > short yarn is generally loose and has a rich handle. Most sewing threads, knitting yarns and wool are staple fibers.

< /p >

< p > 2. < a href= "http://www.91se91.com/news/index_c.asp" > filament yarn < /a > /p >

< p > yarn processed directly from polymer solution is divided into three types, namely, 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.

< /p >

< p > filament yarn has good strength and evenness, and can be made into very fine yarn. It has poor moisture absorption, easy to take static electricity, smooth and cool handle, and cool.

< /p >

< p > 3. reeling (Sao): raw silk reeled from cocoons.

< /p >

< p > 4.: split film yarn: polypropylene film, cut or divided into the required width, and then stretched into split film wire, used for carpet, pile fabric bottom cloth, woven packaging bag.

< /p >

< p > (three) according to the dyeing and finishing process of yarn, < /p >

< p > 1. mercerized yarn: cotton yarn is treated with sodium hydroxide and tension is added to make the yarn luster strength change.

< /p >

< p > 2. singeing yarn: burning the gas or electric heating to burn the yarn surface, and the yarn is more smooth.

< /p >

< p > 3. natural yarn: original yarn, without bleaching to maintain the original color of the fiber.

< /p >

< p > 4. dyed yarn: dyed yarn dyed by primary dyed yarn.

< /p >

< p > 5. bleached yarn: yarn made by boiling and bleaching of raw yarn.

< /p >

< p > (four) according to the spinning process, < /p >

< p > 1. < a href= "http://www.91se91.com" > combed cotton yarn < /a > carding yarn < /p >

< p > combed cotton yarn refers to cotton fibers which are combed and processed on the basis of the general combing of the spinning system.

< /p >

< p > due to the removal of short fibers and impurities, and after many carding, the yarn is parallel and straight in the yarn, the evenness is smooth, the appearance and performance are better than the combed cotton yarn, and it is used for spinning high-grade poplin, sweater and so on.

< /p >

< p > 2. combed yarn and carded yarn < /p >

< p > combed wool yarn is made of fine, long and uniform fine wool as raw material, and is made of combed wool spinning process. The yarn is parallel and straight, and its evenness is smooth. It is used for worsted fabrics such as Hua Dane, Valentine, Paris.

< /p >

< p > combed wool yarn is processed into woollen yarn 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.
