With the market's increasingly stringent requirements for human safety, health and ecological environmental protection, chemicals that newly disable and restricted chemicals are prohibited and used in textile aids in recent years have been introduced. The chemical restrictions also reflect the trend and legal constraints of the current market. There are mainly the following new developments.
1. The requirements for the restrictions on the dotyle and polysuvania and the ampiration of polyzhenyl are more stringent.
Polybenzene is two kinds of environmental hormones with dietary and polyal benzene. They are extremely difficult to decompose and biodegradation. In the environment, they are rich in lipophilic and high -growth accumulation. Best. Its mutant and carcinogenicity is 10 times higher than that of the known carcinogenic ampalin, which is several times higher than that of 3,4-benzene, nitrosamine, and polychlorine benzene. Or during combustion, preparation of wood preservatives, when using some coating additives, halogen flame retardants and waste and waste liquids during the preparation of some fluorescent whitening agents. In today's market, it is divided into five groups according to its different toxic homogeneous objects, which stipulates a stricter limit.
2. Disable fluoride greenhouse gas
At present, the continuous increase in the content of greenhouse gas in the atmosphere is the main reason for the gradual increase in global temperature. According to the report of the United Nations Research Group in the United Nations Climate Change, in order to limit the concentration of greenhouse gas CO2 in the atmosphere to 450 × 10-6, Within, the entire world will have to be reduced by 50%to 80%. At present, the most release of CO2 is mineral fuel coal.
The emission of VOC, especially the high VOC, is also one of the main causes of the gradual rise in global temperature. It is a wide range of high VOC. Generally, it is below 8 carbon hydrogen hydrogen hydrogen hydrogen hydrogenation compounds, alcohol, ether, ketone, ester, and ester. Amide, halogen compounds, unsaturated hydrocarbons, and aromatic hydrocarbon compounds, miscellaneous compounds such as tetraphidanu, tetrahydrology, tetrahydromazole, methylpyamine, and methyl morpholine are all in this column. Fluoride greenhouse gases not only affect global temperatures as high VOCs, but also destroy the ozone layer, form an empty hole, and accelerate the rise of global temperature. Therefore, in order to reduce the emission of environmental greenhouse gases, fluoride greenhouse gases must be disabled.
3. New restrictions on flame retardant
According to the requirements of Eco-Label and Eco-TEX Standard 100, the organic synthetic flame retardant circulating on the market has problems that are harmful to the human health and pollution ecological environment except for ten bromine diodes.
Recents
(1) The banned flame retardants include chlorine chloride (C10 ~ C13), pinthorrine (PBOPE), and octa bromodyl ether (OBDPE);
(2) The flame retardant that cannot be detected is two (2,3-di bromide) phosphate;
(3) A new restrictions on the ten bromine diodel ether. Ten bromine diodes have been spent 10 years in the European Union and studied 588 risk assessment projects. The environment is polluting no pollution and no harm and included in the exemption list, but the EU clearly explicitly expressed the content of commercial ten bromo glycopylene, which should be greater than 97.4%, the content of nine bromine diodes is less than 2.5%, eight bromybenzenyl ether, and pentthopylene ether The content of the waiting content is not greater than 1000 mg/kg, but at the end of 2007, some large textile companies in Europe and the United States still proposed a new limit boundary for ten bromine diodes. kg).
4. Other new restrictions
(1) New requirements for organic tin compound restrictions, according to the requirements of the ECO-TEX Standard 100, the organic tin compounds on textiles only refer to DBT, TBT, TPHT, and its content except for TBT to infant products that cannot exceed 0.5mg/kg, everything else is It cannot exceed 1 mg/kg;
(2) DINP and DIDP are confirmed to be safe and risky. DINP and DIDP are dexyl -altericate and bonitic acid di kinds. (PVC products close to consumers) of phthalate plasticizers;
(3) For new restrictions on asbestos fiber, the 2008 edition Eco-Texstandard 100 added asbestos fiber as a harmful substance and restricted;
(4) Expand the disabled organic solvent. Because some of the organic solvents belong to VOC and the other part is AOX, they will endanger human health and ecological environment. Therefore Eco-Tex Standard100 is stricter.
