Today's international market has put forward strong requirements for safety and ecologicalness in textiles. No matter how much the various certification systems and various textile companies have the requirements for these requirements, in order to facilitate consumer identification and purchase, the safety of textiles is basically basically the safety of textiles. The requirements, that is, meet the following six requirements:

1. No VOC (no volatile organic compound)

VOC is a command organic organic compound, such as titozhopine, diopine, styrene, ethylene cytotane, cytototane, chlorine, formaldehyde, aromatherapy, gasoline, kerosene, white essential oil, polygon aromatic aroma Family hydrocarbon compounds (such as taron), etc., will cause great harm to human health and surrounding environment. Therefore, many foreign countries have formulated VOC regulations. At present Switzerland and others also have VOC laws.

2. No or low FA (no formaldehyde or low formaldehyde)

Regarding the content of formaldehyde (FA) in textile aids, regulations have been promulgated at home and abroad. Many regulations and standards in the international market recently have stricter requirements for formaldehyde content in chemical restrictions on brand textile seller. According to these requirements, many domestic and foreign textile auxiliary manufacturers have developed a lot of low formaldehyde (formaldehyde content <75 × 10-6) and formaldehyde-free additives to replace formaldehyde-containing additives, including color solid agents, anti-wrinkle-free hot perculation Solving agents, adhesives, cross -linking agents, dispersers, flame retardants and waterproof oil -proof agents. From the current situation analysis, it is possible to replace the existing foundation. It is possible to achieve textile aids without formaldehyde or low formaldehyde.

3. No DS (non -risk chemistry)

DS refers to dangerous chemicals with low ignition points. For example, the acetone ignition point is -20 ° C. It is a dangerous chemical substance. At present, in order to ensure that the textile auxiliary does not contain risk chemicals, it is prepared with high fire points and safe chemicals. 135 ° C, the ignition point of the glycol is 110 ° C, etc., and it is safer to replace the acetone to prepare the textile auxiliary. Another example is that the fire point of fire oil is low, and it uses the emulsification thickened, flammable, explosive, and highly dangerous. Now it is replaced with synthetic thickeners without mineral oil or low mineral oil. The safety of coating printing.

4. No EH (no environmental hormone)

At present, the environmental hormones (EH) recognized in the international market include polychlorine hormone -related environmental hormones, alkylphenol, polychlloristophenylene, and compounds of two evils and phthalates. 26 species such as chloride phenol, organic tin compounds, diezyl, and nitrozethere are 37%of the number of environmental hormone varieties. These environmental hormones enter the textile auxiliary in different ways: (1) as raw materials; (2) as the final product; (3) as a by -product during the preparation of the auxiliary; (4) produce.

5. No PFOS and PFOA (non -influented fluorotensionate and sulfonic and whole fluoribida)

Both PFOS and PFOA are organic fluoride. At present, the restrictions on them in the international market are very strict. It is a security issue worthy of attention in today's textile auxiliary.

6. No AOX (unspoken organic halide)

AOX is the English abbreviation of adsorbable organic halide, which refers to organic halide that can be adsorbed with activated carbon. Because AOX will react under certain conditions to generate multi -halogenzene and to carcinogens such as PHDDO (PHDDO) and polyal bonrene (PHDF), it is very harmful to the human health and ecological environment. Many varieties in textile aids belong to AOX, which can be summarized as the following five categories: (1) halogen -containing organic carriers; (2) chlorine hydrocarbon solvents; (3) halogen consolidation agent; Treatment agent; (5) polyvinyl chloride.
