This document is Part 9 of GB/T 29493 Determination of harmful substances in textile dyeing and finishing auxiliaries, of which the following parts have already been issued:
——Part 1: Determination of the prohibited or restricted flame retardants;
——Part 2: Determination of perfluorinated compounds (PFCs).
——Part 3: Determination of organotins;
——Part 4: Determination of polycyclic aromatic hydrocarbons (PAHs);
——Part 5: Determination of free formaldehyde in emulsion polymers;
——Part 6: Determination of isocyanate groups in polyurethane prepolymers;
——Part 7: Determination of monomeric diisocyanates in polyurethane coating agent;
——Part 8: Determination of residual monomers in polyacrylate;
——Part 9: Determination of acrylamides.
Introduction
The ecological security of textile products is an important requirement of global textile and apparel trade. For textile dyeing and finishing auxiliaries, as special chemicals for textiles, strengthening the detection and control of harmful substances from the source is conducive to reducing the risk of harmful substances in downstream textile products and ensuring personal health and safety.
At present, there are many requirements for the control of harmful substances at the consumer end of the textile industry. GB/T 29493 aims to formulate the detection method standard of main harmful substances in the textile dyeing and finishing auxiliaries industry. GB/T 29493 is proposed to be composed of 9 parts, which target different harmful substances, respectively.
——Part 1: Determination of the prohibited or restricted flame retardants.
——Part 2: Determination of perfluorinated compounds (PFCs).
——Part 3: Determination of organotins;
——Part 4: Determination of polycyclic aromatic hydrocarbons (PAHs).
——Part 5: Determination of free formaldehyde in emulsion polymers.
——Part 6: Determination of isocyanate groups in polyurethane prepolymers.
——Part 7: Determination of monomeric diisocyanates in polyurethane coating agent.
——Part 8: Determination of residual monomers in polyacrylate.
——Part 9: Determination of acrylamides.
In recent years, the types of organotin compounds concerned by the upstream and downstream of the industrial chain have gradually increased. This document is revised in combination with the focus of the industry and the progress of testing technology, which improves the scientificity and applicability of the standard, realizes the source detection and control of organotin compounds, and is conducive to promoting the reduction and substitution of harmful substances in the industry.
