According to the varieties, there are upland cotton and island cotton

According to the staple length, there are ordinary cotton and long-staple cotton

In addition, there is a set of international and national standards. A more comprehensive and detailed classification standard is basically implemented based on several common standards such as lint length, tensile strength, cotton purity, gloss, etc. Generally speaking, the longer the cotton lint, the higher the tensile strength, and the purer the grade, the higher the grade. The higher. This is a very professional issue. There are hundreds of pages of national and international standards.

In general, long-staple cotton is the highest grade of all cottons. The growth conditions of long-staple cotton are relatively harsh, and it is not just a matter of variety. Generally speaking, only areas with long sunshine hours and dry climate can produce high-quality long-staple cotton.

Among the most famous long-staple cottons in the world, Egyptian long-staple cotton is the most famous. Egyptian long-staple cotton is famous for its long lint, high tensile strength and excellent luster. It is the largest cotton in the world. Cotton is the first choice for most brand-name textiles. Other famous long-staple cottons include American Pima cotton, Peruvian long-staple cotton, Xinjiang Aksu long-staple cotton, Indian long-staple cotton, etc. For example, Xinjiang long-staple cotton is famous for its super-long lint, but its glossiness is slightly worse than Egyptian long-staple cotton.

It is also important to note that not all Egyptian cotton, Xinjiang cotton, American cotton, and Peruvian cotton are long-staple cotton. The ones that must be labeled as long-staple cotton are the real long-staple cotton. , this also has relevant standards. When buying long-staple cotton products, you must pay attention to the fact that they must have a special long-staple cotton label before you can buy them. There are too many people selling them like sheep. As far as I know, most of the so-called high-end textiles sold in China are made of ordinary cotton rather than long-staple cotton.

Colored cotton: Colored cotton is a new thing. It was once popular a few years ago, but has gradually disappeared in the past two years. The advantage of colored cotton is that there is no printing and dyeing process, and the cotton is directly colored; the disadvantages are also obvious, the color is single, the tone is too deep, and the price is expensive. Real colored cotton only comes in 4 colors, and the tones are all dull. If you see colorful cotton products with bright colors, they are definitely fake.

The difference between imported cotton and domestic cotton:

Generally speaking, the quality of Chinese cotton is relatively poor. Because the channels for promoting improved varieties are chaotic, the quality of Chinese cotton is uneven. Xinjiang Due to the good climate, the cotton planting industry is systematic and the quality is relatively high; the quality of cotton in Shandong, Hebei, Jiangsu and other places is chaotic.

American cotton, the varieties of American cotton are well controlled and the planting level is high. However, due to the use of mechanical picking, there are more fiber breaks. However, in general, the textiles produced by American cotton are better than those produced in China. The quality of cotton----As for the quality of textiles, cotton plays an extremely important factor. Indian cotton has better varieties, is well managed, and is of similar quality to American cotton. Generally speaking, imported cotton is better than domestic cotton.

Note: If any product that claims to use imported cotton does not carry the special mark of imported cotton, it is false, because the United States and other national cotton associations will authorize domestic companies that use their cotton to label their trademarks or hangtags. Print its registration mark on it. However, those who claimed to use imported cotton did not have this mark. 100 used domestic cotton because the company did not obtain this authorization.

Although China is the world's largest cotton importer, more than 95% of the textiles made from cotton imported into China are exported. Most of the so-called high-end brands in China do not have their own spinning mills or weaving factories at all, and many even have no production plants at all, and they just rely on advertising to play the brand. The raw materials they purchase are also as cheap as possible.

On the contrary, well-known international brands (not sold in China) either own their own spinning mills and weaving factories, and fully control the production process to finely control quality; or they designate an excellent spinning mill in the industry. Spin mills or weaving mills supply designated raw materials for themselves (many of them purchase high-grade cotton themselves and designate spinning mills and weaving mills to order production).
