What are the types of yarns used in clothing accessories

(A) According to the raw materials of yarn
1. Pure spinning yarn
Gold and silver yarn from a fiber raw materials, such as: pure cotton yarn, pure wool, pure silk, pure linen, pure chemical fiber yarn.
2. Blended yarn
The yarn spun by two or more kinds of fiber mix. Such as polyester-cotton, polyester-linen, wool-viscose yarn.

(B) According to the fiber state in the yarn
1. Short fiber yarn:
Yarn made by twisting short fibers together. Usually 15~100 short fibers are twisted to form a single yarn, and 2 or more single yarns are combined and twisted to form a line.
Short yarns generally have a looser structure and a fuller feel. Most sewing threads, knitting yarns and wool yarns are short fibers.
2. Filament yarn
Directly from the polymer solution spun into the filament processing of yarn, according to the structure, gold and silver yarn is divided into monofilament, compound filament, compound twist three. Monofilament consists of a filament, used to weave socks, pantyhose, headscarves, swimwear, etc.; compound silk consists of several monofilaments, there are many silk fabrics woven from compound silk, such as plain soft satin, etc., used for suit lining, underwear, etc.; compound twisted silk is made from compound silk by twisting, according to the use of different twist, weaving crepe fabric.
Filament yarn has good strength, uniformity, can be made into very fine yarn, poor moisture absorption, easy to static electricity, feel smooth and flat, cool.
3. Reeling (Sao) out silk: raw silk reeled from cocoons.
4. Split film silk: polypropylene film sheet, after cutting or scratching and other techniques split into the required width, and then stretched to make a split film silk, gold and silver thread for carpets, pile fabric backing, woven packaging bags.

(C) according to the yarn dyeing and finishing and post-processing points
1. Mercerized yarn: Cotton yarn is treated with sodium hydroxide and tension is added to change the intensity of yarn luster.
2. Burnt yarn: The yarn surface is burnt off with burning gas or electric heat to make the yarn brighter and cleaner.
3. Original color yarn: Original color yarn, unbleached to keep the original color of the fiber.
4. Dyeing yarn: The original color yarn is dyed by cooking and refining to make color yarn.
5. Bleached yarn: Yarn made by boiling and bleaching of the original color yarn.

(D) According to the spinning process
1. Combed cotton yarn and combed cotton yarn
Combed cotton yarn refers to cotton fiber in the spinning system on the basis of ordinary combing and combing processing of cotton yarn.
Due to the removal of short fibers, impurities, and after several combing, the yarn in the fiber parallel straight, uniform, smooth, appearance and performance better than the general combing cotton yarn, used for spinning high-grade poplin, sweatshirts, etc.
2. Combed wool yarn and rough combed wool yarn
The fiber used in combed wool yarn is made of fine, long and even quality wool as raw material, and according to the combed wool spinning process, the fiber in the yarn is parallel and straight, even and clean, used in wada, vanadine, pailiji and other worsted wool fabrics.
Rough combed wool yarn is processed into wool yarn by the rough spinning wool spinning system with shorter processing process, the fiber length is not uniform, the fiber is not straight enough, the structure is sparse, the surface is hairy, used for coat tweed, facecloth and carpet.
