Ecological textile testing

At present, products that can be affixed with "eco-textiles" certification are the products with the highest level of safety in textiles. The concept of eco-textiles originated mainly from the “OEKO-TEX STANDARD 100” promulgated by the International Association for Research and Testing of Ecological Textiles in 1991. It emphasizes the use of post-consumer waste disposal; processing in the production process; and the products are harmless to users. At present, the most influential ecological textile certification in the world is the eco-textile certification "Oeko-Tex" of the International Association for Ecological Textiles Research and Inspection and the European Union's eco-label "Eco-Label". China also issued the national standard GB/T 18885-2002 "Technical Requirements for Ecological Textiles" on November 22, 2002. We believe that textiles that meet these requirements will provide you with peace of mind and comfort.

pH value

The pH of human skin is between 4.5 and 6.0, and it is slightly acidic to protect the skin against bacteria and viruses. As people get older, the skin becomes more and more neutral and cannot be as 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 imparts functions such as shrink-proof, anti-wrinkle, and ironing-free to textiles. This volatile substance can be easily released from the fabric, thus impairing the health of the human body and, in particular, irritating the respiratory mucosa.

Extractable heavy metals

Plants absorb heavy metals from the soil during the planting process. Heavy metal is present in textile post-treatment processes and in various dyes. The accumulation of heavy metals in the human body will accumulate in 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/sensitized/carcinogenic dyes

The dyes in fabrics are in contact with the skin for a long period of time, and their safety is undoubtedly very 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 believed to be reduced to aromatic amines that are detrimental to human health. Some dyes that are highly dispersed in water, the molecules are very fine and may be absorbed by long-term contact with the skin. Some of these dyes are considered sensitized and carcinogenic.

Phthalates

Phthalates, a commonly used plasticizer, are added to plastics and coatings to enhance their performance. Recent studies have shown that some o-benzenes can have adverse effects on children's development, so there are strict restrictions on toys that are imported into infants.

Organic tin

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

Color fastness

Color fastness is the basic requirement of consumers for product performance and directly reflects product quality. Dye loss not only affects the appearance of garments, dyes are more likely to be absorbed by the body through the skin. Four indicators of color fastness are selected in the eco-textiles standards: water stains, perspiration (acid/alkaline), friction (dry/wet), and saliva (especially infants). The color fastness to saliva and perspiration of baby clothes is particularly important because infants can absorb dyes through saliva and sweat.
