Prius-Bio tech has extremely high safety manufacturing requirements for printed products that come into contact with the skin, such as mask fabric and spunlace non-woven fabric.
First of all, the whole product needs to pass the MSDS (Material Safety Data Sheet) test. Allow the overall composition of the product to be fully described and let the customer know the validity and authenticity of the material. Second, make a comprehensive analysis of the product's hazard identification, first aid measures, operational storage, toxicological information, and other applicable regulatory information. In product-related tests, the degree of pigment fixation and the safety of the pigment on the skin are particularly important.
Prius-Bio Tech uses water-based environmentally friendly pigments as printing colorants, and tests related harmful substances such as azo in the pigments according to the EU EN14362. The test results show that the printed masks, printed spunlace non-woven fabrics and printed non-woven products manufactured by Puyongqiang Company all meet this standard.
Regarding the degree of color fixation of printing pigments, we have adopted methods such as alcohol resistance test (75% alcohol), 72-hour constant temperature test (60 degrees Celsius) and acid and alkali resistance test to ensure that the printed pattern has the characteristics of long-lasting color fixing to the greatest extent.
