According to the standard of toxic substances in the 2000 Eco-Tex Standard 100 new version of the test textiles, relates to the disabled dye allergic dyes, Discount Yard Flags direct carcinogenic dyes and the dyes of the acute toxicity, and also includes lead, antimony, chromium, exceed the limited indicator of cobalt, copper, nickel, mercury and other heavy metals, formaldehyde content exceeds the limited indicator, organic pesticides more than the limited indicator dye, as well as containing environmental hormones, contain chemical substances that cause environmental pollution, containing variability chemicals containing persistent organic pollutants such as dyes.

Measured from the molecular structure analysis and dyed fabrics that carcinogenic aromatic amine as an intermediate for the synthesis of dyes, including azo dyes and other dyes, Discount Yard Flags such as has not been fully purified, even trace the presence of the dye in the case of the disabled list. Market about 70% of synthetic dyes is azo-based, widely used direct dyes, acid dyes, reactive dyes, metal complex dyes, disperse dyes, cationic dyes and polycondensation dyes, etc., containing azo structure . The azo dyes used not only for textile and dyeing, and is also used for dyeing leather, paper, food. It should be noted that the azo dye itself will not under normal circumstances the human body harmful effects, but part of the carcinogenic aromatic amine intermediate synthesis of azo dyes, when the long-term contact with human skin, Beach Warning Flags and human normal metabolism the release of substances in the process of combination and reduction reaction occurs the azo fracture, Discount Yard Flags re-generate carcinogenic aromatic compounds, these compounds by the body re-absorb After activation, the human cell structure and function change, so changes in the adult body lesions induced factors that increase the carcinogenic can be difficult. Disable the dye is not limited to, azo dyes, and in other structures of the dyes, such as sulfur dyes, restore, dyes and additives may also be implied in these harmful aromatic amines has been banned.
A. Direct dye direct dye cellulose fibers with the large number of dye, in
Two. Consumption of acid dyes acid dyes in the world after curing, direct and disperse dyes, acid dyes in the dye is disabled in Germany nearly 30. More harmful aromatic amine species involved in the distribution of benzidine, dimethyl benzidine, o-anisidine, o-toluidine, of benzidine, 4 – amino -3,2 – dimethyl azo a wide range such as benzene and carcinogenic dye itself
Within. Chromatography is mainly concentrated in red and black, Promotional Feather Flags the other distributed in the chromatography of the orange, purple, brown. Include: weak lime R (Acid Orange 45), weak acid scarlet H (Acid Red 285), acid black NT29 (Acid Black 29). Advertising Feather Flags And Banners
In addition, released by the 2000 Eco-Tex Standard 100 version in the new disabled Acid Dyes four kinds: there are two kinds of direct carcinogenic dyes known, they are CI Acid Red 26, Discount Yard Flags CI Acid Violet 49; involved allergic to the dye is CI Acid Black 48; related to the acute toxicity of the dye CI Acid Orange 156, CI Acid Orange 165.
Disperse dyes 118 dyes, disperse dyes in Germany, disabled, disabled disperse dyes 6, not included but is disabled by the impact of the 22 kinds of harmful aromatic amines, According to incomplete statistics, there are 14, not including as the composition of the dye compound. Prominent disabled dye CI Disperse Yellow 23, Custom Outdoor Banner Flags which is yellow and red azo disperse dyes,
2000 Eco-Tex Standard 100 version in dye species involved in the allergic disperse dyes accounted for 26 kinds. In addition, a known carcinogenic dyes disperse dyes there are two kinds, Discount Yard Flags which are CI Disperse Yellow 3, CI Disperse BlueA.
Chromophore chromophore naphthol insoluble azo dyes used in many varieties for the MAK (III) A1 (MAK means the maximum workplace concentration) and A2 carcinogenic or suspected carcinogenic aromatic amines, should have been disabled.
