Fibers and regenerated fibers are arranged in sequence.
(3) Cross-twisted yarn-a yarn twisted by two or more different fiber raw materials or single yarns of different colors.
(4) Blended yarn-yarn is made by blending two or more filament fibers to improve some properties.
Third, according to the fiber length of the yarn.
(1) filament yarn-a yarn made by combining, twisting or deforming one or more continuous filaments.
(2) Short fiber yarn-yarn with a certain fineness spun by twisting short fiber can be divided into:
1. Cotton yarn-a yarn made of raw cotton or cotton fiber by pure spinning or blending on cotton spinning equipment.
2. Medium-long fiber yarn-medium-long fiber yarn with a certain wool feeling spun on cotton spinning or special equipment.
3. Wool yarn-yarn made of wool fiber or wool fiber spun or blended on wool spinning equipment.
(3) Blended yarn of filament and staple fiber-refers to the yarn spun by staple fiber and filament through a special method, such as core-spun yarn and wrapped yarn.
Fourth, according to color (dyeing and finishing)
(1) Primary color yarn-yarn with the original color of fiber without any dyeing and finishing.
(2) Bleached yarn-The yarn is bleached and the color is white.
Usually refers to cotton yarn and hemp yarn.
(3) colored yarn-colored yarn of various colors.
(4) colored spinning-colored spinning is the yarn spun by colored fibers.
(5) singed yarn-singed yarn is a yarn with smooth surface after singed.
(6) Mercerized yarn-mercerized yarn, including mercerized cotton yarn and mercerized wool yarn.
Treating cotton yarn in a certain concentration of alkaline solution to make the yarn have silky luster and high strength, that is, forming mercerized cotton yarn; Remove the scales of the fibers in the wool yarn and it becomes a mercerized wool yarn.
Mercerized yarn is soft and has no irritation to skin.
5. According to the spinning process
(1) Combed yarn-The yarn spun by combing engineering is called combed yarn.
Compared with carded yarn, combed yarn has better materials, straight and parallel fibers, excellent yarn quality and fine yarn fineness.
(2) Carding yarn-The yarn spun through general spinning engineering is called carding yarn, which is slightly different from wool spinning.
(3) Waste spinning —— The yarn with poor quality combed and spun with inferior raw materials is called waste spinning.
Usually the yarn is thicker and contains more impurities.
Six, according to the yarn linear density-cotton yarn is divided into coarse yarn, medium yarn, fine yarn and superfine yarn according to the linear density.
(1) Roving-Roving refers to the yarn with linear density greater than 32 tex.
(2) Zhongte yarn-Zhongte yarn refers to the yarn with linear density of 2 1 ~ 3 1 tex.
(3) Fine tex yarn-Fine tex yarn refers to yarn with linear density of 1 1 ~ 20 tex.
(4) superfine yarn-superfine yarn refers to the yarn with linear density of 10tex or less.
A yarn made by blending two or more fibers is called blended yarn.
The naming rule is to write the ingredients with high blending ratio of fiber raw materials on the front or above. When the blending ratio is the same, it is generally arranged in the order of natural fiber, fiber and man-made fiber.
For example, a blended yarn of 65% polyester and 35% cotton is named polyester/cotton yarn; The blended yarn of 50% viscose fiber and 50% acrylic fiber is called clear/viscose yarn, etc.
