This document replaces GB/T 18885-2009 Technical specifications of ecological textiles and the following main technical changes have been made with respect to GB/T 18885-2009: ——Standards such as GB 18401-2010 are added to the Normative reference (see Clause 2); ——The limit requirements for the release of total lead, total cadmium and nickel are added, and the prohibition and restriction requirements for polycyclic aromatic hydrocarbons, perfluorinated compounds, residual solvents, residual surfactants, wetting agents and UV-light stabilizers are added (see Table 1); ——The requirements for color fastness to wet rubbing of products for infants and young children and products in direct contact with skin are added (see Table 1); ——Annexes G, H, I, and J are added (see Annexes G, H, I and J); ——The assessment of organic volatile substances is deleted (see Table 1 of the Edition 2009); ——the “Determination of abnormal odors - sniffing method” in Annex G is deleted (see Annex G of Edition 2009); ——The name of "phenol compounds" in Table 1 is modified and "o-phenylphenol” is adjusted to "other chemical residues” (see Table 1 of this document; Table 1 of Edition 2009); ——The limit requirements is modified, and "≤" is modified to "<"; the formaldehyde content limit of products that are not in direct contact with skin is modified from "300 mg/kg" to "150 mg/kg"; the color fastness to water of products for infants and young children is increased to Grade 3-4, and the limit value of o-phenylphenol in products for infants and young children and other products is modified from "50 mg/kg" and "100 mg/kg" to "10 mg/kg" and "25 mg/kg" respectively (see Table 1 of this document; Table 1 of Edition 2009); ——The test method of decomposable carcinogenic aromatic amine dyes in pure polyester fiber products is modified. The pretreatment is carried out according to Annex B of GB/T 17952-2011. If aniline or/and 1,4-phenylenediamine is detected, re-sampling and pretreatment shall be carried out according to Annex A of GB/T 23344-2009 (see 6.5 of this document; 6.9 of Edition 2009); ——The definition and description of 3.1 "ecological textile” is improved (see 3.1 of this document; 3.1 of Edition 2009).
