Let's talk about the importance of green dyes

Hello, dear. The following is for you, the development of green dyes is first of all to develop substitutes for dyes and auxiliaries that are banned due to carcinogenic aromatic amines. Due to the limit values of extractable heavy metals and formaldehyde on textiles, it is necessary to develop metal-free, low-formaldehyde, formaldehyde-free dyes and additives.

China's dyes and additives industry has actively carried out the research and development of green stool dyes, and has provided the market with a variety of new varieties that meet the requirements of ecological and environmental protection in the past ten years, basically meeting the needs of ecological textiles. I hope mine will help you and have a great life!

The advantages of natural dye dyeing are:1Environmentally friendly:

Natural dye dyeing does not contain toxic substances and will not cause pollution to the environment; 2.Bright color: The color of natural dye dyeing is bright and the dyeing effect is good; 3.

Abrasion resistance: Natural dyeing has strong abrasion resistance, and the dyed clothes can maintain the original color for a longer time.

Cons: 1The dyeing effect is unstable:

The dyeing effect of natural dye dyeing is greatly affected by environmental factors, and the dyeing effect is not stable enough. 2.Slow dyeing speed: natural dyes are slower and take longer to dye them; 3.

High dyeing cost: The cost of dyeing natural dyes is higher, and the cost of dyeing is also higher.

2。Environmental significance: Natural dyeing is characterized by the sustainable use of natural resources, and at the same time can avoid the serious pollution problem of chemical dyes.

3。Aesthetic level significance: natural dyeing can not only get a variety of bright high chroma colors, but also can get a large number of delicate intermediate colors, elegant colors are the most generous gift of nature, worthy of our savoring.

In addition, through different times of counter-dyeing with different hues, you can dye a richer and more timeless color level.

4. The significance of market demand: With people paying more and more attention to environmental protection, market demand has become more and more urgent, especially the demand of the high-end market has emerged.

Dyeing wool fabrics and silk with natural food coloring and chemical synthesis of food coloring is a new technology successfully experimented by Professor Yu Boling of Beijing Institute of Fashion Technology. Wool, cashmere and silk were originally pure natural high-grade fibers, but fortunately, in the process of printing and dyeing with traditional chemical dyes, they were not only polluted to varying degrees, reducing their performance, but also polluting rivers, lakes, seas and land with a large amount of sewage. Natural food pigments are extracted from plants, which are non-toxic, tasteless, pollution-free, safe and reliable, light-resistant, heat-resistant, and soluble in water.

Food coloring is a chemical synthetic dye with the exact same chemical structure as natural dyes, and its safety has been announced by the Food and Agriculture Organization of the United Nations and the World Health Organization, and it is fully compliant with food standards, and can be safely used in food, medicine and health products, let alone used to dye clothes. Wool and silk fabrics dyed with food coloring are bright in color and soft to the touch.

Professor Yu Boling has also developed a series of dyes and color fixing methods for the artistic dyeing of cotton, rayon, nylon, polyester, silk, knitted wool, cashmere sweaters, buttons of various materials, etc., no matter which of the above fabrics can maintain the original feel and style of the fabric. His hand-painted dyes can satisfy the desire of those who like to be different to chant poems and paint on their own clothes, whether it is silk, wool, or cotton, they can paint as much as they want, and paint wherever they want.

The most direct ** of green dye should be the dye plant. Pure natural plant dyes can be extracted from numerous dye plants and used for dyeing natural fibers without synthetic dyes.

At present, this kind of dye has been successfully developed in China and used for large-scale production.
