\n The above analyzes the prohibited and restricted substances that may appear in each process of printing and dyeing. It is worth noting that pre-treatment and dyeing require multiple washings, so many toxic and harmful substances are washed away, and only trace amounts remain. After finishing, There is no water washing, so once the general finishing process additives contain banned substances, it is easy to cause the cloth surface to become excessive. \ufffd\u3002

\n DHTDMAC, DSDMAC and DTDMAC<\/strong>are all cationic surfactants and are raw materials for making softeners. Although the softeners made from them have excellent softening effects, they will kill biological bacteria. Biodegradability is very poor and can easily be absorbed by sludge during sewage treatment and pollute agricultural products. \ufffd\u3002\u56e0\u6b64\uff0c\u572820\u4e16\u7eaa90\u5e74\u4ee3\u521d\u5df2\u5728\u5fb7\u56fd\u3001\u8377\u5170\u7b49\u56fd\u5bb6\u505c\u6b62\u4f7f\u7528\uff0c\u8fd1\u5e74\u6b27\u76df\u51b3\u5b9a\u7981\u6b62\u4f7f\u7528.
