Extractable heavy metal
Plants will absorb heavy metals in the soil during the planting process, and there are heavy metals in the textile post-treatment process and various dyes. Heavy metals enter the body and accumulate in the organs. Once this accumulation reaches a certain level, it will have a serious impact on our health. We simulate human sweat and extract these heavy metals to detect the content of heavy metals in textiles.
Azo / Allergenic / Carcinogenic Dyes
The long-term contact of dyes in clothing fabrics with skin is undoubtedly important. Azo dyes are a common class of dyes and are widely used in the textile and leather industries. However, some of these dyes are thought to be reduced to aromatic amine substances that are not good for human health. Some dyes highly dispersed in water have very small molecules and may be absorbed by prolonged contact with the skin. Some of these dyes are thought to have sensitizing and carcinogenic effects.
Phthalates are a commonly used plasticizer and will be added to plastics and coatings to enhance their performance. Incoming studies have shown that some o-benzenes can have adverse effects on children's development, so there are strict restrictions on toys imported by babies.
Organotin has antibacterial and anti-mildew effects, and is used in shoe linings, gloves, and child care products. High concentrations of organotin are neurotoxic when they are absorbed by the body through the skin.
Color fastness is the basic requirement of consumers for product performance and directly reflects product quality. Dye shedding not only affects the appearance of the garment, but the dye is more likely to be absorbed by the body through the skin. In the ecological textile standard, four color fastness indexes are selected. These four color fastnesses are water stain, sweat stain (acid / alkaline), abrasion resistance (dry / wet) and saliva (especially for infants and young children). Color fastness to saliva and sweat stains in baby clothing is particularly important because infants and young children can absorb dye through saliva and sweat stains.
