Certification Standards And Analysis Of Eco Textiles

< p > eco textile certification standard is developed jointly by the German Haines Institute and the Austria Textile Research Institute. It is the most authoritative and most widely used eco textile label in the world.

The product with the certification of "eco textiles" is the highest safety product in textiles.

This kind of ecological textiles focuses on controlling harmful substances such as harmful dyes, formaldehyde, heavy metals, finishing agents, odor and other harmful substances.

< /p >

< p > Application: this standard prohibits and < a href= "http://" www.sjfzxm.com/news/index_c.asp > < < /a > > the textile contains the following harmful substances: 1. azo < a href= "http://" www.sjfzxm.com/news/index_c.asp > dye > /a > 2.; carcinogenic and sensitizing dyes; 3. formaldehyde; 4. pesticides; 5. chlorophenols; 6. chlorinated benzene and toluene; 7. extractable heavy metals; 8. color fastness; /a value; 10. infant products, o-benzoic acid two formate; 11. organic tin compounds; 11. organic volatile gas; 11. bad smell; and other bioactive products and fire retardant materials;

< /p >

< p > the eco textile certification standard divides the textile into four levels: < /p >

< p > Level 1: baby products (textiles used by children under 3 years of age); < /p >

< p > Second: direct contact with skin; < /p >

< p > Third: do not directly contact the product with < a href= "http:// www.sjfzxm.com/news/index_c.asp" > skin > /a > /p >

< p > Fourth: decorative materials (carpet, wallpaper, Simmons, etc.) < /p >

< p > January 2001, the State Environmental Protection Administration approved and started implementing the "eco textiles" standard. Ecological textiles should meet the following technical requirements: < /p >

< p > products should not be treated with chlorine bleaching.

< /p >

< p > Product shall not be mildew proof and finishing.

< /p >

< p > product should not be added pentachlorophenol and four chlorophenol.

< /p >

< p > the product must not be mildew, gasoline or toxic aroma.

< /p >

< p > products should not be used to decompose toxic aromatic amine dyes, carcinogenic dyes and dyes that may cause allergies.

< /p >

< p > formaldehyde, extractable heavy metal content, pH value, color fastness and pesticide retention of products should meet the requirements.

< /p >

< p > warm reminder: the surface of human skin is generally weak acid, so as 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.

< /p >

< p > on the surface, color fastness does not seem to involve 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.

< /p >

< p > 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.

< /p >

< p > 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 furniture), have only formaldehyde content below 300ppm.

< /p >

< p > can be compared with 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.
