Textiles such as curtains and sheets, or formaldehyde-containing and decomposable aromatic amine dyes
Curtains, wall coverings, bed sheets, duvet covers, bedding, clothing, towels, socks, hats and other products are all textiles, and must also implement the "National Textile Products Basic Safety Technical Specifications" (GB 18401-2010). The standard is the most basic requirement for ensuring that textile products are harmless to human health.
Textiles are divided into three categories, Class A is baby products; Class B is products that directly touch the skin, such as sheets, quilt covers, towels, etc.; Class C is products that are not directly in contact with the skin, such as curtains, bedspreads, wall coverings, etc. The formaldehyde content, pH value and color fastness of the product are also becoming more and more relaxed from A to C as the product category requires. If the formaldehyde content of bedding products, curtains, etc. exceeds the standard, the formaldehyde remaining on the textile will gradually be released into the indoor air. The human body wears clothes containing formaldehyde, formaldehyde is combined with human sweat or hydrolyzed to produce free formaldehyde, which is strongly stimulated by respiratory and skin contact, causing respiratory inflammation and skin inflammation. Excessive pH will cause inflammation such as itching of the skin, especially for children with delicate skin.
According to the standard requirements, Class A, B, and C products are required to disable the “decomposable carcinogenic aromatic amine dyeâ€. It is understood that products dyed with such dyes will be mixed with substances released by the human body during long-term contact with human skin metabolism to produce a carcinogenic aromatic amine compound, causing human diseases and inducing cancer.
In addition, all products require “no odorâ€. Professionals explain that in the production process of textiles, in order to achieve the flame retardant or antistatic effect of the product, some additives will be added during the processing, but if the rinse is not in place, some chemicals will remain in it, resulting in odor. . If you smell mildew, high boiling oil (such as gasoline, kerosene), fishy smell, aromatic smell, it is odor.
TIPS smells and identifies inferior products
Although ordinary consumers cannot identify product quality by some means, textile industry experts say that there are some simple exclusion methods that do not say good quality products. First of all, you can smell it, as long as you smell the product, it is best not to buy this product; secondly, you can look at the color, the color is too bright or dark products do not buy.
Bezels with a lot of patterns should be vigilant, because the patterns are glued to the textiles, and the possibility of containing formaldehyde is relatively large. Finally, you can use a damp cloth to slap on the product you want to buy. If you find that the color is off, the color fastness is not good. It is best not to choose such a product.
Mattress, sofa and other soft furniture, formaldehyde, benzene-based pollution can not be ignored
Mattresses and sofas may also cause excessive pollution due to material. The structure of the sofa is divided into fabric, foam and frame. According to Sun Shudong, assistant director of the National Furniture and Indoor Environmental Quality Supervision and Inspection Center, fabrics are textiles and may contain pollutants such as formaldehyde, PH-exposed and decomposable aromatic amine dyes as described above. In foams, because of the need to use glue to bond, unqualified foam products may contain volatiles such as formaldehyde, benzene and TVOC. The frame is made of wood-based panels. If it is unqualified, it may contain volatiles such as formaldehyde and benzene. If the fabric used for making the mattress, the sponge and other bedding materials have excessive formaldehyde, the filled mattress will of course exceed the standard. Unqualified foam will also contain a large amount of adhesive, and formaldehyde pollution should not be underestimated.
According to Sun Shudong, at present, only spring soft mattresses have national standard, and there is a limit on the formaldehyde content. Although the brown mattress can be referred to the relevant standards for production and testing, it does not indicate which standard is the standard, and it is easy to cause confusion in execution. Sofa products only require odors, but odors are only based on smell, and the control of pollutants is not too meaningful.
TIPS software furniture new national standard introduced during the year
Since there is no corresponding standard to limit the harmful substances of soft furniture, consumers should go to the brand store to buy brand products when purchasing soft furniture. The standard for the limit of harmful substances in soft furniture has already been formulated, but the specific time for the introduction has been delayed for various reasons. The Jinghua Times reporter learned from relevant sources that the National Standards Committee recently revealed that the limit standards for harmful substances in sofas, mattresses and wooden furniture were confirmed to be introduced this year. However, due to standard reforms, there is no specific date for the introduction.
