Cotton yarn production and manufacturing methods are relatively complex, in general, there are two spinning methods, namely, comb spinning and comb spinning. (1) comb spinning process: cotton → open cotton → combing → and strip → roving → yarn → fall cylinder (manual winding and automatic winding two) → finished product inspection. (2) combing spinning process: cotton → open cotton → combing → and strip → strip roll → combing → and strip → coarse yarn → fine yarn → drop barrel (divided into manual winding and automatic winding two kinds) → finished product inspection. Cotton yarn has a wide range of uses, it can be used as woven yarn, such as: bed sheets, covers, curtains and other home textile series. It can also be used as knitting yarn, especially combed yarn can be used to produce high quality textiles, such as sweatshirts, fine number poplin, etc. Cotton yarn can also be used to produce special industrial electrician's yellow wax cloth, tire cord cloth, high-speed sewing thread and embroidery thread, etc. Sewing thread is the thread used for sewing textile materials, plastics, leather products and stapling books and magazines. Sewing threads are characterized by sewability, durability and appearance quality. Depending on the material, sewing thread is divided into three types: fiber, chemical fiber, and hybrid; the characteristics of sewing thread also have their unique properties depending on the material.
--- Good heat resistance, elasticity, abrasion resistance, moisture resistance, suitable for high-speed sewing and durable pressing. Long-staple cotton thread: It is made of long-staple cotton, combed, burnt, mercerized, and high-density plus read, so the tension is better than ordinary combed cotton. Often for cotton clothing and other cotton fabrics for sewing purposes specifications 20/2 (60/4), 20/3 (60/6) 40/2, 40/3, 20/9 cotton thread: generally divided into combed and combed two parts, 100 cotton thread available for sewing for the full combed cotton. Generally with 402, 202, 203 more. Is the cotton area of the cotton combed and burnt wool made. Cotton thread is often used for cotton clothing and other cotton fabrics for sewing purposes.
---Smooth surface, soft luster, good elasticity and high temperature resistance. It is used for sewing tweed garments and satin fabrics; rayon is brightly colored, but has poor strength, very poor moisture absorption, and is less expensive. Mostly used for machine embroidery. Cotton yarn is made from cotton fiber and can be divided into combed yarn and combed yarn according to the different spinning processes. Combed yarn is made of cotton fiber spun by ordinary spinning system. The combed yarn is made of cotton fiber spun by combing spinning system. The combed yarn is made from raw materials with straight and parallel fibers, less knotting, good luster, even dryness and high strength, which are mostly used for weaving fabrics. Cotton yarn is widely used, it can be used as woven yarn, such as: bed sheet, quilt cover, curtain and other home textile series. It can also be used as knitting yarn, especially combed yarn can be used to produce textiles with high quality requirements, such as sweatshirts, fine number poplin, etc. Cotton yarn can also be used to produce special industrial electrical yellow wax cloth, tire cord fabric, high-speed sewing thread and embroidery thread, etc. Cotton fabrics are made of cotton, produced by the textile process, with moisture absorption, heat resistance, alkali resistance, hygiene and other characteristics. Generally speaking, cotton fabrics have better moisture absorption and heat resistance, and wear. Some of the work clothes of industries with higher requirements for moisture absorption of clothing can choose cotton fabrics for processing. For example, school uniforms in summer, etc.
