Some people may say that there is something green and non-green in textiles? I haven’t bought it so much for decades. This is the understanding of textiles and clothing for most consumers at this stage.
In fact, scientists have found that many consumers buy colorful clothing and bedding, and after wearing it, they find redness, dermatitis and even pus, accompanied by vomiting, dizziness, etc., which can lead to cancer. The formaldehyde content of chemically dyed textiles is seriously exceeded, and free formaldehyde is released during the wearing process. It also strongly stimulates the respiratory mucosa and skin through the human respiratory tract and skin contact, causing respiratory inflammation and skin inflammation. It also irritates the eyes.
Secondly, some chemical dyes also pose a threat to human health. Some azo dyes in chemical dyes can decompose toxic aromatic amines and penta-oxytetrachlorophenol. There are also some dyes that can cause skin irritation and carcinogenesis. The latest medical research shows that women's premature birth is also associated with exposure to the above-mentioned harmful substances.
In addition, the surface layer of human skin is weakly acidic to prevent invasion of germs. The pH value of chemically dyed textiles, if not controlled in neutral or acidic, ie 4.0-7.0, will cause damage to human skin, sweat and saliva in human body. Enzymes can also promote the decomposition of chemical dyes.
China's General Administration of Quality has introduced the formaldehyde content standards for textile products (including fabrics and accessories) sold in China. According to the standard, the formaldehyde content of baby products such as saliva, outerwear, pajamas, hats, etc. within 24 months should be in parts per million. Twenty or less. Products that are in direct contact with the skin, such as bust, knitted underwear, quilt cover, bedding, etc., should be less than 75 parts per million. Sweaters, trousers, skirts, coats, etc., which are not in direct contact with the skin, should be less than three-thousandths of a percent. Indoor (including car, boat, aircraft) supplies, such as sofa covers, bedspreads, wall coverings, etc. should be less than three tenths.
The fact that chemically dyed textiles endanger the human body has attracted the attention of governments. The EU banned the use of some azo dyes a few years ago. The Chinese government expressly stipulates that it is not allowed to use medium and primary school uniforms for the printing and dyeing of harmful and allergenic chemical pigments.
Whether this standard is already a safety standard, and whether the manufacturer can self-discipline and many other issues remains to be seen.
As a consumer how to choose green textiles, how to take measures to protect themselves? Our suggestions are as follows: buy new clothes or textile products should not be worn directly, soak the water several times to make the residual formaldehyde release and dissolve. In particular, non-iron clothes have the highest formaldehyde content. Try to use natural weaving: color wool, colored cotton wool, colored silk, polylactic acid weaving PAL, nail weiwei and other new bio-compatible and environmentally-friendly weaving products.
China has become the world's largest production base for colored cotton. Production reached 6,000 tons, accounting for one-third of global production. Colored cotton products have begun to be launched in batches. Although the colors are monotonous, it is better to choose colored cotton products as much as possible for their own health.
Natural color silk, the current sericulture has cultivated several kinds of natural colored silk, this silk product will be widely welcomed by people, it can be said that the revolution of silk production. However, at present, it is still a stage of trial and perfection, and one of the three primary colors has been produced. It takes a long time to produce colorful colored silk. Despite this, it gives consumers more choices.
The new weaving dimension produced by nanotechnology enables polyester and nylon to be intertwined in units of tens of nanometers. Due to the refraction of light, the colorless and transparent material appears to have four colors of blue, red, green and purple. Dimensions will be used for clothing and coatings, but garments made from such woven fabrics are not yet available.
Plant color products: If textiles are produced using natural weaves and plant colors, this will be 100% green textiles in the strict sense. Plant colors can produce thousands of colors like chemical colors. Can meet people's needs for color. Plant color is derived from the colored juice of the roots, stems, leaves, flowers and fruits of plants. Made by purification, it is non-toxic and harmless. For example, the yellow textile dyed with the strawberry juice, the yellow liquid dyed with the yellow liquid of the silk flower, and of course the green textile.
The era of widespread application of plant colors has arrived, and the research on plant color purification, quantification and color fastness has been completed. It can be said that it is a revolutionary victory in the textile printing and dyeing industry. Plant fuel dyeing products have been put on the market in batches, and consumers can use them with confidence.
The research and development of plant color extraction, purification and color fastness are the result of collaboration between Zhang Meizhi, a famous plant color research expert and designer in mainland China, and Zhou Lingqi, another expert.
