Types of cotton yarn

Classification method-There are many ways to classify cotton yarn.
(1) According to the thickness:
① Coarse yarn: Cotton yarns of 17 counts and below are all coarse yarns. Mainly used for weaving thick or piled and looped cotton fabrics, such as coarse cloth, flannel, and solid cloth; ② Medium yarn: Cotton yarns of 18-27 counts are medium yarns, which are used to weave plain cloth, twill, and satin and other general fabrics; ③ Fine yarn: Cotton yarns of 28 counts and above are used to weave fine cloth poplin, high-grade needle and woven fabrics.

(2) According to the spinning principle:
① Free-end spinning (such as air spinning and siro spinning) ② Two-end grip spinning (such as ring spinning and compact spinning) Another popular one is vortex spinning, which is improved by using the principle of air vortex spinning.

(3) According to the cotton grade:
① Carded yarn: It is a ring-spun yarn spun by a spinning process without a combing process, which is used for general needle and woven fabrics; ② Combed yarn: It uses high-quality cotton fiber as raw material. When spinning, it adds a combing process compared to carded yarn. The yarn spun is of high quality and is used to weave high-end fabrics, such as high-end poplin and fine cloth; ③ Waste yarn: It refers to yarn spun from all waste cotton processed during the spinning process. It is used to weave low-grade cotton blankets, flannel and foreskin cloth; ④ New-type yarn: It is yarn spun using a new spinning system.

(4) According to twist direction:
① Back-hand twist (also known as Z twist) yarn, which is the most widely used in various fabrics; ② Smooth-hand twist (also known as S twist) yarn, which is used as the weft yarn for weaving flannel.

(5) Classification by yarn usage:
① Warp yarn is the yarn parallel to the edge of the fabric in the woven fabric, with greater strength and generally greater twist; ② Weft yarn is the yarn perpendicular to the edge of the fabric in the woven fabric, with lower strength requirements than warp yarn, and generally lower twist than warp yarn, maintaining a certain degree of softness; ③ Knitting yarn is required to be clean, uniform, and with a small twist to prevent breakage during weaving and bending; ④ Industrial yarn such as tire cord, conveyor belt yarn, sanitary and medical yarn, etc.

(6) According to yarn dyeing and finishing and post-processing:
① Natural yarn (also known as original color yarn): maintains the original color of the fiber, used for weaving original color grey cloth; ② Dyed yarn: the original color yarn is smelted and dyed to make colored yarn for color woven fabric; ③ Color spun yarn (including mixed color yarn): the fiber is first dyed and then spun to make yarn, which can be woven into fabrics with irregular stars and patterns; ④ Bleached yarn: made from original color yarn after smelting and bleaching, used for weaving bleached cloth, and can also be interwoven with dyed yarn into various color woven products; ⑤ Mercerized yarn: cotton yarn that has been mercerized. There are mercerized bleached and mercerized dyed yarns, which are used to weave high-end color fabrics; ⑥ Singed yarn: the fuzz on the surface of the yarn is burned off by a singeing machine to make yarn with a smooth surface, which is used to weave high-end products.

(7) Classification by use: ① Weaving (woven) yarn: twist coefficient greater than 360. ② Knitting yarn: twist coefficient less than 330

(8) Classification by yarn-making equipment: ring spinning, air spinning (OE), siro spinning, compact spinning, rotor spinning, vortex spinning, electrostatic spinning, etc.

(9) Classification by yarn form: hank yarn, cheese yarn.
