The cultivation and use history of original natural colored cotton is earlier than that of white cotton. According to reports, the original natural colored cotton is native to the American continent, and the indigenous peoples of Peru have cultivated and used colored cotton thousands of years ago. The earliest record of the cultivation of colored cotton in my country is that in 1819, cloth woven from purple cotton (brown) was exported to Europe in Jiangsu and Zhejiang.


However, with the rapid development of the textile and printing and dyeing industries and the maturity of breeding technology, people bred white cotton fibers with good fiber quality and high yield through special dyeing and spinning into beautiful and colorful fabrics, while the original natural colored cotton is unstable due to its unstable color. , Poor fiber quality, low output and other shortcomings were left out, and then was replaced by white cotton with high value in use.


Since the 1970s, with the increasing attention of the international community to environmental protection issues, the rise of people advocating for nature, returning to nature, and the rapid development of biotechnology, conditions have been created and opportunities have been provided for the development and utilization of colored cotton. Therefore, the major cotton-producing countries in the world have carried out research on colored cotton using biotechnology, and have achieved preliminary results.


The longitudinal direction of natural colored cotton is similar to that of white cotton. They are all flat bodies with irregular turns. The middle part is thicker, the root part is slightly thinner, and the tip part is the thinnest. Fibers with good maturity are in the shape of twisted ribbons in the longitudinal direction, with more turns; fibers with poor maturity are in the shape of thin ribbons with few crimps.


The cross-section of colored cotton fibers is similar to that of white cotton, both of which are round waists with cavities in the middle. The difference is that the cross-sectional area of green cotton is smaller than that of white cotton, that is, the fiber is thinner than white cotton. The secondary cell wall is much thinner than white cotton, and the cell cavity is much larger than white cotton, which is U-shaped. The cross-section of brown cotton is similar to that of white cotton. The secondary cell wall and cross-sectional area of the fiber are plumper than that of green cotton, but the cell cavity is larger than that of white cotton.


The environmental protection characteristics and natural color of colored cotton are in line with the tastes of modern people. Because it has not been chemically treated, some yarns and fabrics still retain some cotton seed hulls, reflecting the feeling of returning to nature.


Therefore, the product development makes full use of this feature to achieve soft, natural and elegant color, with a casual style, and then infiltrate the fashion trends of the season.


 The image of the clothing product reflects the solemnity and elegance without losing the ease and nature, and the image of the home textiles reflects the warmth and comfort while giving people a back-to-nature feeling.
