As the market has put forward increasingly stringent requirements for human safety and health and ecological environmental protection, new banned and restricted chemicals in textile auxiliaries have been continuously introduced in recent years, especially reflected in the chemical restriction clauses proposed by large textile companies and brand textile sellers, and also reflecting the current market trends and new legal constraints. The main new trends are as follows.

3.1 Stricter restrictions on polyhalogenated dibenzo-p-dioxins and polyhalogenated dibenzofurans
Polyhalogenated dibenzo-p-dioxins and polyhalogenated dibenzofurans are two environmental hormones that are extremely difficult to decompose and biodegrade. They are lipophilic and highly bioaccumulative in the environment. They are the most toxic environmental pollutants known. Its mutagenicity and carcinogenicity are 10 times higher than the known carcinogen aflatoxin, and several times higher than 3,4-benzopyrene, nitrosamines and polychlorinated biphenyls. They are mainly produced in the waste and waste liquid during the thermal decomposition or combustion of AOX, the preparation of wood preservative pentachlorophenol, the use of certain paint additives, and the preparation of halogen flame retardants and certain fluorescent whitening agents. In the current market, it is divided into five groups according to its different toxicity homologues, and more stringent restrictions are stipulated.

3.2 Banning fluorinated greenhouse gases
It is generally believed that the increasing content of greenhouse gases in the atmosphere is the main cause of the gradual rise in global temperatures. According to the 2007 report of the United Nations Climate Change Research Group, in order to limit the concentration of greenhouse gas CO2 in the atmosphere to 450×10-6, the world will have to reduce emissions by 50%~80%. At present, the fossil fuel coal releases the most CO2.
The emission of VOC, especially high VOC, is also one of the main reasons for the gradual rise in global temperature. The range of high VOC is very wide, generally including aliphatic hydrocarbons, alcohols, ethers, ketones, esters, amides, halogen compounds, unsaturated hydrocarbons, aromatic hydrocarbons, heterocyclic compounds such as tetrahydrofuran, tetrahydropyran, tetrahydrothiazole, methylpyridine, methylmorpholine, etc. with less than 8 carbon atoms. Fluorinated greenhouse gases not only affect global temperature as high VOC, but also destroy the ozone layer, form holes, and accelerate the rise in global temperature. Therefore, in order to reduce the emission of environmental greenhouse gases, fluorinated greenhouse gases must be banned.

3.3 New restrictions on flame retardants
According to the requirements of Eco-label and Eco-Tex Standard 100, organic synthetic flame retardants circulating on the market, except decabromodiphenyl ether, are harmful to human health and pollute the ecological environment.
Recently, some textile companies have proposed chemical restrictions that further refine and tighten commonly used flame retardants:
(1) New banned flame retardants include chlorinated paraffin (C10~C13), pentabromodiphenyl ether (PBOPE), and octabromodiphenyl ether (OBDPE);
(2) New flame retardants that cannot be detected include di(2,3-dibromopropyl) phosphate;
(3) New restrictions have been proposed for decabromodiphenyl ether. Decabromodiphenyl ether is a halogen-containing flame retardant that the European Union has spent 10 years studying 588 risk assessment projects. The conclusion is that it poses no risk to human health, no pollution or harm to the environment and is included in the exemption list. However, the EU clearly stated that the content of commercial decabromodiphenyl ether should be greater than 97.4%, the content of nonabromodiphenyl ether should be less than 2.5%, and the content of octabromodiphenyl ether and pentabromodiphenyl ether should not exceed 1,000 mg/kg, but at the end of 2007, some large textile companies in Europe and the United States still proposed a new limit for decabromodiphenyl ether, stipulating that the limit by mass fraction is 0.1% (i.e. 1,000 mg/kg).

3.4 Other new restrictions
(1) New restrictions on organotin compounds. According to the requirements of Eco-Tex Standard 100, organotin compounds on textiles only refer to DBT, TBT, and TPhT. Except for TBT, which cannot exceed 0.5 mg/kg for infant products, the content of other substances cannot exceed 1 mg/kg;
(2) DINP and DIDP are confirmed to be safe and risk-free. DINP and DIDP are diisononyl phthalate and diisodecyl phthalate, respectively. They are phthalate plasticizers mainly used in textiles, leather, toys, packaging, furniture, plastics, etc. (PVC products that are in close contact with consumers);
(3) New restrictions on asbestos fibers. The 2008 edition of Eco-TexStandard 100 added the regulation that asbestos fibers are listed as hazardous substances and are restricted;
(4) The scope of banned organic solvents has been expanded. Since some organic solvents are VOCs and others are AOXs, both of which are harmful to human health and the ecological environment, more and more organic solvents are required not to be detected, and it is stricter than Eco-Tex Standard 100.
