Packaging, storage and transportation of combed cotton yarn: cotton yarn can be divided into cheese yarn and hank yarn according to different uses. The inner packaging of cotton yarn is a plastic bag, with the label of the factory name, product name and specification, registered trademark name, grade, weight, batch number, package number, yarn quantity and package date. The outer packaging of cotton yarn is mainly carton or plastic woven bag, and the packaging should be clean, dry and firm, suitable for long-distance transportation. The inspection period of cotton yarn is one year in the north and half a year in the south. Exceeded must be checked. Check the main items: mildew, moth-eaten, water stains, pollution, damage, etc.

Egyptian long-staple cotton yarn is of good quality, and its fibers are soft and long, generally 33-39 mm, up to 64 mm in length; fineness is 7000-8500 m/g, width 15-16 microns; high strength, 4-5 grams Force/root, the fracture length is 33 to 40 kilometers; there are many twists and turns, 80 to 120 pieces/cm. There are some hybrid varieties with sea island cotton as the male parent and upland cotton as the female parent. The fibers are longer, but the fineness and strength cannot reach the sea island cotton index, commonly known as upland long-staple cotton. Egyptian long-staple cotton yarn is made of cotton fiber. According to different spinning processes, it can be divided into carded yarn and combed yarn. Carded yarn is a yarn spun from cotton fibers through a common spinning system.

Better cotton yarn is because cotton fiber is a bad conductor of heat and electricity, with low thermal conductivity, and because cotton fiber itself has the advantages of porosity and high elasticity, a large amount of air can be accumulated between fibers, and air is a bad conductor of heat and electricity. Therefore, pure cotton fiber textiles have good thermal insulation, and wearing pure cotton fabrics makes people feel warm. Better cotton yarn fabrics have good heat resistance. When the temperature is below 110 °C, it will only cause the evaporation of water on the fabric and will not damage the fibers. Therefore, pure cotton fabrics have no effect on the fabrics under normal temperature, wearing, washing, printing and dyeing. Improves the washability and wearability of pure cotton fabrics. Alkali resistance: cotton fiber has a great resistance to alkali. Cotton fiber will not be damaged in alkali solution. This performance is conducive to washing pollution and removing impurities after taking it, and it can also dye pure cotton textiles. , printing and various technological processing to produce more new varieties of cotton weaving.
