Pure cotton yarn is made of cotton fiber and can be divided into carded yarn and combed yarn according to different spinning processes. Carded yarn is a yarn spun from cotton fibers through a common spinning system. Combed yarn is a yarn spun from cotton fiber through a combed spinning system. Combed yarn is made of raw materials. The fibers in the yarn are straight and parallel, with less knots, good luster, evenness and high strength. This type of cotton yarn is mostly used for weaving fabrics. Cotton yarn is widely used, it can be used as yarn for weaving, such as: bed sheets, quilt 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 singlets, fine poplin, etc. Cotton yarn can also be used to produce electrical yellow wax cloth for special industries, tire cord fabrics, high-speed sewing threads and Embroidery thread etc. Pure cotton fabric is made of cotton as raw material and produced by textile technology, which has the characteristics of moisture absorption, heat resistance, alkali resistance, hygiene and so on. Generally speaking, pure cotton fabrics have better moisture absorption and heat resistance, and are more comfortable to wear.
Some work clothes in industries that require relatively high moisture absorption of clothing can choose pure cotton fabrics for processing. For example, summer school uniforms, etc. According to the national standard, the yarn quality is rated according to the quality index and weight unevenness. Cotton yarns are graded according to evenness, neps, and number of impurities. Among them, the quality index mainly refers to the strength of the yarn, which reflects the durability and durability of the fabric to a certain extent. The grade of the yarn mainly reflects the difference in the thickness of the yarn and the appearance defects, which directly affect the appearance of the fabric, such as the evenness of the grain, the clarity and the size of the shadow, etc. The level of yarn quality is closely related to production management, process conditions, mechanical conditions, technical operation level, the quality of raw cotton and its reasonable use. Pure cotton fabric is a textile made of cotton as raw material, which is interwoven vertically and horizontally by warp and weft yarns through a loom. At present, according to the actual source of processed cotton, it is divided into native cotton fabric and cotton fabric.
Cotton with a cotton content of more than 60 is pure cotton. Don't think that pure cotton is cotton. They still have differences. Characteristics of ring-spun pure cotton yarn 1. Hygroscopicity: Cotton fiber has good hygroscopicity. The skin feels soft and not stiff. If the humidity of the cotton cloth increases and the surrounding temperature is high, all the moisture contained in the fiber will evaporate, so that the fabric will maintain a water balance state and make people feel good. 2. Heat preservation: Because cotton fiber is a poor conductor of heat and electricity, the thermal conductivity is low, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can accumulate between the fibers, and the air is not good for heat and electricity. It is a good conductor, so pure cotton fiber textiles have good heat retention, and wearing pure cotton fabrics makes people feel warm. 3. Heat resistance: pure cotton fabrics have good heat resistance. When the temperature is below 110°C, it will only cause moisture evaporation on the fabric and will not damage the fibers. Therefore, pure cotton fabrics have no effect on the fabric when worn at room temperature, washing, printing and dyeing, etc., thus improving the quality of the fabric. It ensures the washable and wearable performance of pure cotton fabrics. 4. Alkali resistance: Cotton fiber has great resistance to alkali. Cotton fiber will not be damaged in alkali solution. This property is beneficial to washing and removing impurities after taking it. It can also be used for pure cotton textiles. Dyeing, printing and various processes are carried out to produce more new varieties of cotton weaving.
5. Hygiene: Cotton fiber is a fiber whose main component is cellulose, which contains a small amount of waxy substances, nitrogenous substances and pectin. Pure cotton fabric has been tested and practiced in many aspects, and the fabric has no contact with the skin. It is beneficial and harmless to the human body for a long time, and has good hygienic performance.
