Cotton yarn is made of cotton fiber. According to the different processes of spinning, it can be divided into general combing gauze and fine comb. The gauze is a gauze made of cotton fiber through a common spinning system. The sterite yarn is a gauze made of cotton fiber combed and spinning system. The combing yarn is used for raw materials, and the fiber is stretched straight and parallel in the yarn, less, good, good, dry, strong, and strong. This type of cotton yarn is mostly used for weaving fabrics. The cotton yarn is widely used. It can be used as a weaving gauze, such as: sheets, covered, curtains and other home textile series. It can also be used as a knitted yarn, especially the combing yarn can be used to produce textiles with higher quality requirements, such as sweatshots, thinfouse silk silk, etc. Cotton yarn can also produce special industrial yellow wax cloth, tire curtain cloth, high -speed sewing thread, and high -speed sewing threads and high -speed sewing threads and high -speed sewing threads and high -speed sewing threads and high -speed sewing threads. Embroidery lines, etc. Cotton fabrics are cotton as raw materials and produced by textile processes. They have the characteristics of hygroscopic, heat resistance, alkali resistance, and hygiene. Generally speaking, cotton fabrics have better hygroscopic heat resistance and wear. Some workwear in industries with high demands for clothing can choose cotton fabrics for processing. For example, school uniforms in summer.
　　According to national standards, the quality of the yarn is on cotton yarn reviews according to the quality indicators and weightlessness. According to the dry uniformity and cotton knot, the number of impurities grains is rated to cotton yarn. The quality indicator mainly refers to the strength of the yarn, which reflects the fabric durability and durability to a certain extent. The grade of the yarn mainly reflects the thickness differences and appearance of the yarn. It directly affects the appearance of the fabric, such as the uniformity of the lines, the clear and the size of the shadow. The quality of the yarn and production management, process conditions, mechanical conditions, technical operations, the advantages and disadvantages of the original cotton, and the reasonable situation of their use have a close relationship. Cotton fabrics are cotton as raw materials and textiles that are intertwined by the latitude gauze through the weft vertical and horizontal. The sources of cotton that are currently processed are divided into native cotton fabrics and cotton fabrics. Cotton with a cotton amount of more than60is cotton. Don&39;t think that cotton is cotton, and they still have different places.
　　Features of ring spinning pure cotton yarn
　　1. Moisturizing: Cotton fiber has better hygroscopic absorption. Under normal circumstances, the fiber can absorb water from the surrounding atmosphere, and its water content is 8-10, so it contacts people&39;s skin and makes people feel soft and soft and soft. Not stiff. If the humidity of the cotton cloth is large and the surrounding temperature is high, the amount of moisture contained in the fiber will evaporate and disperse, so that the fabric will keep the water balance and make people feel good.
　　2. Insulation: Because cotton fiber is a poor conductor of thermal and electricity, the thermal conductivity coefficient is low, and the cotton fiber itself has the advantages of polyitability and high elasticity. Good conductors, so cotton fiber textiles have good insulation, wearing cotton fabrics and clothing to make people feel warm.
　　3. heat resistance: Cotton fabrics are well -resistant. When below 110 ° C in Celsius, it will only cause water evaporation on the fabric without damaging fiber. The influence has improved the performance of cotton fabrics and washing and wearing resistance.
　　4. Alkali resistance: Cotton fiber has a large resistance to alkali. Cotton fiber is in alkali solution, and fiber does not cause damage. This performance is conducive to the washing of pollution after taking. Perform dyeing, printing and various processes to produce more new cotton -weaving varieties.
　　5. Hygiene: Cotton fiber is fiber, and its main component is cellulose, containing a small amount of waxy substances and nitrogen -containing and pectin. Pure cotton fabrics have been inspected and practiced in many aspects, and there is no contact with the skin with the skin. It is good for the human body for a long time and good sanitation.
