Certification Standards And Analysis Of Eco Textiles

Description: Eco textiles refer to the textile products that meet the technical requirements of environmental labeling products and the textiles that are tested in the textile industry, which are harmless or less harmful to the environment, and are made harmless to human health by making rational use of these raw materials.

The concept of eco textiles is mainly derived from the "OEKO-TEX STANDARD 100" issued by the International Association for the study and inspection of eco textiles in 1991. It emphasizes the use of waste disposal and production processes, and products are harmless to users.

Scope of application: prohibition and restriction of this standard textile Contains the following harmful substances: 1. azo dyes; 2. carcinogenic and sensitizing dyes; 3. formaldehyde; 4. pesticides; 5. chlorophenols; 6. chlorinated benzene and toluene; 7. extractable heavy metals; 8. color fastness; 9.pH; 10. infant products, o-benzoic acid two formate; 11. organic tin compounds; 11. volatile organic compounds; 11. odor; bioactive products and Flame retardant material Otherwise, 15.PFOS, PFOA.

　　 Eco textiles The certification standard divides textiles into four levels:

Level 1: baby products (textiles used by children under 3 years old);

Level second: direct contact with skin products;

Class third: no direct contact with skin products;

Grade fourth: decorative materials (carpet, wallpaper, Simmons, etc.)

In January 2001, the State Environmental Protection Administration approved and began implementing the "eco textiles" standard. Ecological textiles should meet the following technical requirements:

Products should not be treated with chlorine bleaching.

2. Products must not be mildew proof and finishing.

Products should not be added pentachlorophenol or four chlorophenol.

4. The product must not be mildew, gasoline or toxic aroma.

Products should not be used to decompose toxic aromatic amine dyes, carcinogenic dyes and dyes that may cause allergies.

The content of formaldehyde, extractable heavy metals, pH value of leach liquor, color fastness and pesticide retention should meet the requirements.

Warm reminder: human skin surface is generally weak acid, in order to prevent the invasion of germs. Therefore, the pH value of textiles is controlled by neutral and weak acidity (pH:4.0-7.0), which is harmless to human health.

On the surface, color fastness does not seem to concern the ecological problems of textiles. In fact, enzymes in human sweat and saliva can promote dyestuff decomposition and cause harm to the human body. Therefore, underwear should be made with no dyed or dyed fabrics.

Natural fibers will inevitably encounter diseases and insect pests in the growth process and use insecticides. It has been found that there are 22 kinds of insecticides which can cause various hazards to human body. Therefore, the residues in textiles must be strictly controlled.

The limit value of formaldehyde for infants and toddlers is 20ppm, while the formaldehyde limit value of products directly related to skin, such as bedding, underwear, shirts and loose blouses, is 75ppm. Products that do not directly contact the skin, such as coats (men's and women's suits, coats) and household decorations (tablecloths, decorative fabrics, curtains, fabrics and mattresses on the furniture), have only formaldehyde content. Below 300ppm.

It can be compared to an apple with a formaldehyde content of at least 20ppm. Formaldehyde in cosmetics is used as a preservative. Products such as mouthwash must be announced if the formaldehyde content exceeds 100ppm. According to the law, the formaldehyde content of textiles must be stated if 1500ppm or higher.
