Ecological textile testing

    At present, products that can be affixed with "eco-textile" certification are the products with the highest safety level among textiles. The concept of ecological textiles is mainly derived from the "OEKO-TEX STANDARD 100" promulgated by the International Ecological Textile Research and Inspection Association in 1991, which emphasizes the disposal of waste after use; the treatment in the production process; and the product is harmless to users. At present, the most influential eco-textile certification in the world is the eco-textile certification "Oeko-Tex" of the International Eco-Textile Research and Inspection Association and the EU's eco-label "Eco-Label". my country also promulgated the national standard GB/T 18885-2002 "Technical Requirements for Ecological Textiles" on November 22, 2002. We believe that textiles that meet these requirements can bring you peace of mind and comfort.

pH value

The pH of human skin is between 4.5 and 6.0, slightly acidic can protect the skin and resist bacteria and viruses. As people get older, their skin will become more and more neutral and cannot be antibacterial as before. Textiles that are neutral or slightly acidic are beneficial to the human body. If the pH of the textile is too high or too low, the skin surface is easily damaged.

formaldehyde

Formaldehyde gives textiles functions such as shrink-proof, anti-wrinkle, and non-ironing. This volatile substance is easily released from the fabric, thus harming the health of the human body, especially causing irritation to the respiratory mucosa.

Extractable heavy metals

Plants absorb heavy metals in the soil during the planting process. Heavy metals are present in the post-treatment process of textiles and various dyes. Heavy metals enter the human 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/sensitizing/carcinogenic dyes

The dyes in clothing fabrics are in contact with the skin for a long time, and its safety is undoubtedly very important. Azo dyes are a large group of common dyes, which are widely used in the textile and leather industries. However, some of the dyes are considered to be reduced to aromatic amines that are harmful to human health. Some dyes that are highly dispersed in water have very small molecules and may be absorbed in long-term contact with the skin. Some of these dyes are thought to have allergenic and carcinogenic effects.

Phthalates

Phthalates are commonly used plasticizers and are added to plastics and coatings to enhance their performance. Recent studies have shown that some o-benzenes have an adverse effect on the development of children, so there are strict restrictions on toys imported by infants.

Organotin

Organotin has antibacterial, anti-mildew and other biological killing effects, and is used in shoe linings, gloves, child care products and other products. High concentrations of organotin are neurotoxic after being absorbed by the human body through the skin.

Color fastness

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. Four color fastness indexes are selected in the eco-textile standard. The four color fastnesses are water stain, sweat stain (acid/alkaline), rub resistance (dry/wet) and saliva (especially for infants and young children). The color fastness to saliva and perspiration of baby clothing is particularly important because infants and young children can absorb dyes through saliva and perspiration.
