Stranded yarn is a thread made of two or more single yarns bonded together. The strands can also be combined and bonded in a certain way, compound bonded strands, such as double strands, triple strands and multi-stranded strands. It is mainly used for sewing threads, knitting threads or medium-thick and strong fabrics. Conventional strands are usually made of cotton or blends of two or more single yarns bonded together, and in recent years there are fancy strands made of two or more different single yarns bonded together, such as: cotton and blends, plain yarn and bamboo yarn, and plain yarn and filament, etc. Cotton yarn is made from cotton fiber and can be divided into combed yarn and combed yarn according to different processes of spinning. 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. Combed yarns are made from raw materials with straight and parallel fibers, few knots, good luster, and uniform stripes. Cotton yarn is widely used, 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 textiles with high quality requirements, 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. 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. According to the national standard, the quality of yarn is graded according to the quality index and the weight unevenness rate of cotton yarn. Cotton yarn is rated according to the uniformity of the strip and the number of cotton knots and impurities. The quality index mainly refers to the strength of the yarn, which reflects the durability of the fabric to a certain extent. The grade of yarn mainly reflects the difference of yarn thickness and appearance of defects, which directly affects the appearance of the fabric, such as the uniformity of the pattern, the size of clear and shadow.The quality of yarn is closely related to the production management, process condition, machinery condition, technical operation level, the quality of raw cotton and its reasonable use. Cotton fabric is the raw material of cotton, through the loom, by the warp and weft yarn vertical and horizontal sinking interwoven textiles. At present, according to the actual processing of cotton sources and distinguished as the original cotton fabric and cotton fabric. Cotton content of more than 60 cotton is pure cotton, do not think that pure cotton is cotton, they are still different places.
