Cotton‘s contribution to the earth and mankind

We all know that white cotton has a long history. What about natural colored cotton? In fact, their planting history is also long. The ancestor of cotton, the "grandfather" of wild cotton fiber, often has brown or other colors. Therefore, we see that the most common colored cotton in the world is pure natural brown cotton for a reason.

Peru has the longest history of planting natural colored cotton in the world. Indians in central and South America began to cultivate and use natural colored cotton as early as 5000 years ago. It was found in the site of a village on the northern coast of Peru. From 3100 BC to 1300 ad, local people began to grow natural colored cotton and weave fishing nets and ropes with this dark brown fiber 。

People like white things, so people choose white cotton for inheritance. In fact, due to the rise of the mechanical textile industry, ordinary white cotton is more convenient for printing and dyeing. Therefore, for industrial convenience, we choose white cotton as the mainstream cotton variety for cultivation, picking, printing and dyeing, spinning and making clothes. White cotton is more widely planted.

Natural colored cotton gradually withdrew from people's vision.

In the middle of last century, with the deterioration of environmental quality and the imbalance of ecological balance, countries all over the world have carried out and produced research on textile products beneficial to health and environmental protection for the health of mother earth. Because of its inherent natural color, natural colored cotton can be made into colored textiles and clothing without dyeing and chemical printing and dyeing, which can be avoided The pollution of printing and dyeing to the environment and the direct harm of dyes to human body are also in line with people's high-end pursuit of green and healthy life.

When it comes to colored cotton, I have to mention Xinjiang, because China colored cotton group has accumulated a planting area of one million mu. The Ministry of agriculture has explicitly prohibited Xinjiang from having transgenic cotton test materials to participate in the multi-year multi-point regional test organized by the seed management station of Xinjiang Uygur Autonomous Region and passed the examination and approval. The test materials must pass the transgenic test of designated scientific research institutes before non transgenic materials can be used After entering the regional test, once the genetically modified materials are found, it is required to withdraw immediately and deal with the participating units. Therefore, the truth is that the 14 new color cotton varieties selected by China color cotton (Group) Co., Ltd. are non genetically modified varieties, and the varieties promoted are their own. The color cotton selected and planted in Xinjiang are non genetically modified cotton
