Recently, some international clothing brands blatantly boycott Xinjiang cotton and its products in their commercial activities based on lies and false information. This behavior has aroused great indignation from the Chinese public, especially the textile and apparel industry! For a time, Xinjiang cotton was pushed to the cusp of the storm. Today, the editor will take you to understand the advantages of Xinjiang cotton!
Support Xinjiang cotton
Xinjiang cotton is famous for its long velvet, good quality, and high yield. This depends on Xinjiang's unique natural conditions. On the one hand, Xinjiang is rich in light and heat resources, with a large temperature difference in summer, which can reach more than 18 hours of sunlight, which is particularly suitable for cotton growth. On the other hand, Xinjiang’s cotton area has a dry climate with severe cold in winter, and the lowest temperature is mostly below -20 degrees. It is not conducive to the overwintering and reproduction of diseases and insect pests. Moreover, Xinjiang has long implemented technical measures for comprehensive prevention and control of diseases and insect pests. The ecological conditions of cotton fields are relatively good, and the cotton is basically free of boll disease, which is conducive to improving cotton yield and quality.
01
fiber length long
The length of cotton fiber is the main basis for determining the grade and price of cotton fiber. Different types of cotton have different fiber length and thickness. The longer the fiber, the higher the quality. The length of the cotton fiber refers to the length of the cotton fiber after straightening (referred to as "length"). It is divided into 7 levels with 1 mm as the step distance, and 28 mm as the standard length. The cotton fiber classification is as follows:
7: 25 mm, including 25.9 mm and below;
6: 26 mm, including 26.0-26.9 mm;
5: 27 mm, including 27.0-27.9 mm;
4: 28 mm, including 28.0~ 28.9mm;
3: 29mm, including 29.0～29.9mm;
2: 30mm, including 30.0～30.9mm;
1: 31mm, including 31.0mm and above;
The fiber length of ordinary cotton is 23～38mm , And the fiber length of Xinjiang cotton is generally 33 ~ 39 mm, the longest can reach 64 mm.
Under the same other conditions, the yarn spun from longer cotton fiber has higher strength and better elasticity, and can be spun into a cotton yarn with finer yarn count and more uniform yarn.
02
fine fiber fineness
cotton fiber fineness is related to variety and maturity. The finer cotton fiber feels softer and feels more comfortable to the skin. The fineness of Xinjiang cotton is generally 1.1 to 1.4 dtex, while the fineness of ordinary cotton fiber is generally 1.3 to 1.7 dtex.
Note: Dtex is abbreviated as Dtex, and the symbol is dtex, which refers to the weight of a 10,000-meter-long yarn at a constant moisture regain, that is, 1dtex=1g/10000m. It is a fixed-length unit. The larger the value, the thicker the yarn, and vice versa.
03
high cotton grade
grade refers to the level of cotton quality. According to cotton's maturity, color characteristics and rolling quality, it is divided into 7 grades, namely grades one to seven. The third grade is the standard grade. The grade below grade 7 is outside grade cotton.
Xinjiang cotton 1 and 2 cotton accounted for more than 80%.
Modern cotton planting and picking in Xinjiang
Xinjiang Shawan , 1.8 million acres of cotton fields, all using Beidou navigation autopilot seeding machines; and more than 70% of Xinjiang cotton fields have adopted new-type mechanized cotton pickers, zzzz6 Collecting, separating, removing impurities, and bundling can be done in one go. Every 30 minutes, a large cotton weighing 2.5 tons can be produced.package.

The history of the development of Xinjiang textile industry
Xinjiang was called the Western Regions in ancient times, with a vast territory and rich resources. Its unique geographical location and natural environment made it a place where humans lived long before they thrived. The textile industry in Xinjiang also has a long history. The world-famous "Silk Road" runs through the entire territory, where the textile technology and culture of various regions converge. “Xinjiang General History·Textile Industry History” mentioned that “the cultivation and utilization of cotton in the history of in Xinjiang was earlier than in the Central Plains. At the latest in the Eastern Han Dynasty, cotton was also used in textiles, and at the same time it was mastered. Printing technology."
Xinjiang's textile industry continued to develop in the following dynasties. In the late Qing Dynasty, Xinjiang's textiles began to be sold to foreign countries. In the 22nd year of Daoguang (1842), Xinjiang exported 42,000 rubles of textiles to Tsarist Russia.
During the period of the Republic of China, textile enterprises in Xinjiang experienced rise and fall, and finally the economy suffered due to the influence of political corruption and war.
In October 1949, Xinjiang was peacefully liberated, and a new page in Xinjiang's history began. The country began to vigorously restore and develop production in Xinjiang, of which the recovery and development of the cotton textile industry is the top priority. On July 1, 1952, the first phase of the Dihua Cotton Textile Factory was completed and put into operation, and was renamed Xinjiang Qiyi Cotton Textile Factory. The completion and commissioning of Xinjiang Qiyi Cotton Textile Factory marked the beginning of Xinjiang's cotton textile industry and laid a solid foundation for the development of Xinjiang's textile industry in the future.
To this day, Xinjiang cotton has become a recognized high-quality natural fiber raw material in the global industry. It satisfies the global rigid consumer demand for cotton textiles and clothing, and is an important raw material guarantee for the healthy and sustainable development of China’s textile industry. . In recent years, not only the cotton planting and production in Xinjiang has remained stable, but the cotton textile and clothing industry has also developed rapidly, which has played an important role in promoting regional economic development, solving the employment of people of all ethnic groups, and improving people's livelihood and well-being. In 2020, Xinjiang will produce 5.2 million tons of cotton, accounting for about 87% of domestic production. As of the end of 2019, there were 808 cotton processing enterprises in Xinjiang, accounting for 84% of the country's total, and the scale of cotton spinning spindles reached 19.91 million, accounting for about 16% of the country's total spindles.
