GB/T18401-2010 "National Basic Safety Technical Specifications for Textile Products" stipulates that infant textile products need to be assessed for saliva color fastness. Saliva color fastness refers to the degree of color retention of textiles under the action of artificial simulated saliva. Textile perspiration color fastness tester can conduct this experiment. Infants and young children like to suck and chew clothes. Under the biochemical action of proteases in human saliva, saliva will promote the decomposition of dyes, which may ingest harmful substances in dyes into the baby's body through the mouth, causing damage to the health of infants and young children. Therefore, saliva color fastness is a color fastness test item specially added for infant clothing. Shanghai Qianshi Precision Electromechanical Technology Co., Ltd. was established in 2012. It focuses on the research and development, design, and production of textile testing instruments, and provides texti...
