The Colorful Plants In The World Are Actually The Best Plant Dyes.

Throughout the year, summer is the most colourful color. The beauty of it is the colorful plants in the big world.

No human ancestors who have ever seen industrial civilization, how do they decorate their clothes with colors? Human nature is contradictory, and for nature's conquest and change, spare no effort to rebuild the material world; the other side is sentimentally attached to and cherished, and never forget to purify the state of mind without losing the pursuit of natural beauty.

In recent years, the return to simplicity in color is such a course.

Not long ago, at the annual meeting of the International Association of green economy held in Beijing, experts introduced green vegetable dye dyeing technology. Now, the new environment-friendly textiles have six dimensions: environmental protection fiber,

Natural auxiliaries, green printing and dyeing, easy to use, waste, easy degradation or regeneration.

Among them, plant dyes can extract pigment from Chinese herbal safflower, dye women's underwear, dye the men's underwear with the color extracted from Radix Isatidis, and provide bacteriostatic and health care.

The listener felt refreshing and fascinated.

From a large number of ancient documents and excavated tombs, we can see that more than two thousand years ago, in the spring and Autumn period and the Warring States period, both Wang Gongguizhou and ordinary people wore products of natural fibers and natural dyes. They did not use pesticides or chemical fertilizers or chemical degumming, boiling and bleaching auxiliaries or wool scouring tablets.

The most common dyeing methods were plant dyes, including herbs, herbs and tea.

With the rise of the second industrial revolution in Britain,

Production has basically replaced the handicraft industry. Chemical synthetic dyes have been invented and brought great influence to the world textile industry.

China is a large textile country. In the past 30 years, it has also caused serious environmental pollution while promoting economic development. Synthetic chemical dyes and auxiliaries used in textile dyeing process contain different kinds of harmful substances in different degrees, which endanger people's health. Especially in the process of synthetic dyeing and chemical processing, the large amount of sewage treatment is difficult and expensive, which causes great pressure on the ecological environment.

Therefore, the development direction of textile industry in the future is to follow the natural harmlessness of ancient law, and to meet the needs of rapid social rhythm.

Gao Guangdong, general manager of Hangzhou color run Technology Co., Ltd., in an interview with sci-tech daily, said that modern plant dyeing technology has made great breakthroughs, and can produce thousands of colors and carry out industrial mass production, thus greatly reducing the production cost of plant dyes.

Natural plant dyestuffs are dyed by natural pigments extracted from natural plants such as flowers, fruits, skins, stems and seeds. The common varieties are walnut skin, mast, safflower, marigold, mulberry, turmeric, madder, bluegrass, safflower, five bezi, etc.

He said that from the perspective of traditional Chinese medicine, Chinese herbal medicine has a health care function on human body. It is a product of green environmental protection. The dyeing wastewater produced by natural plant dyes is simple, environmentally friendly, non-toxic, harmless and pollution-free, and has good biodegradability.

Cai run technology has made Chinese herbal medicine into vegetable industry. It has invested in the construction of Chinese herbal plant planting base, pigment extraction base, and dyed fiber products factory based on advanced multi frequency ultrasonic equipment and processing technology and natural plant dyes and natural auxiliaries.

In recent years, there has been a survey shows that the current market women underwear quality sample inspection pass rate of 70%, the failure of goods mainly concentrated in the color fastness to perspiration is not up to the national quality standards.

The so-called color fastness to sweat, is the human body sweating, the dye in the fabric shedding and pfer to the skin, may be sensitized and carcinogenic to the human body.

Gao Guangdong told sci-tech Daily reporters: "underwear fabrics close to the skin will stain many sweat secretions, sebum and other human secretions during the wearing process. Under certain temperature and humidity conditions, they will become a breeding ground for all kinds of microorganisms, such as pathogenic bacteria, and they will also produce stink.

Moreover, if the fabric is not properly produced in the printing and dyeing process, it is likely to cause cancer.

So in summer, when people wipe sweat with traditional towels, they will smell sour and stink in the bathroom.

In view of these circumstances, Cai run technology promotes the application of ecological, environmental friendly, chlorine free bleaching processing of linen, hemp and jute in dyeing and weaving. Because of the natural antibacterial function of linen and other Chinese herbal medicines, flax and other Chinese herbal medicines do not need to add chemical antibacterial agents to form high safety, high added value and eco-friendly functional fibers, yarns and other textiles.

Towels, socks, etc. made of it.

Up to about 99%.

Moreover, the color fastness accords with the mandatory standard of the national basic safety technical specification for textile products GB18401-2010.

Deng Peihua, chairman of Suzhou Tian Jin Ma Yun new Mstar Technology Ltd, told reporters: "in order to solve the problems of underwear, technicians now develop a" bottoms up pants ", that is, pure natural functional ecological trousers, and use antibacterial flax instead of traditional materials with poor permeability to make underwear.

Chinese herbal medicine is then used as a vegetable dye for fabric. Pigment is extracted from safflower and dyed with women's underwear. The color of men's underwear is printed with the color extracted from Radix Isatidis to achieve the color fastness of chemical dyestuffs.

Compared with the traditional underwear, the underwear has breathability, fast drying and antibacterial properties. It changes the male traditional shorts which are suffocating due to the temperature and humidity of the crotch, and affects the health and comfort. It can also reduce the infection probability of female genital itching and gynecological diseases.

In practice, technical personnel dye natural plant dyes on wool, silk, cotton and hemp and other protein fibers and cellulose fibers, and find that they are natural and soft in color. After processing, they can be widely used in knitted underwear, infant products and household clothing, which make people comfortable, safe and healthy.
