Inspection Of Basic Safety Items For Eco Textiles And Textile Products (2)

Two Eco textiles Detection

2.1 eco textiles Testing items

The testing procedures for Oeko-Tex 200 (test standard) contain 12 main categories: pH value determination, formaldehyde determination, extractable heavy metals, pesticide residues, phenol (chlorphenol and OPP) content, banned dyes, organochlorine carrier, PVC plasticizer (o-phenyl two formate) content, organotin compounds, color fastness, volatile compounds and odor mixture determination, sensitive odor and so on.

It needs to be explained that the detection items of eco textiles are dynamic, and almost every year there will be some new indicators. At present, the testing items of various testing institutions in China are: pH value determination, formaldehyde determination, extractable heavy metals, banned azo dyes, color fastness, odor and so on.

2.2 main technology of ecological textiles testing items

There are three main types of modern eco textile testing technology: chromatography, atomic spectroscopy and molecular spectroscopy. Among them, chromatographic analysis technology is the most widely used.

2.3 eco textile products standard And Tags

There are many textile ecological standards in the world. ISO has classified the standards and labels of ecological products into 3 categories:

The first type is: first, inspect the whole life cycle of the product, that is, the extraction of raw materials, the spanportation of products, production, use and abandonment; (2) voluntary participation; (3) multi product categories; (4) third party inspection and on-site audit representative ecological labels. For example: Europen Eco-Label (EU eco label), Nordu White Swan Labe (Nordic Swan logo), The Blue Angel (German blue angel logo), Flower Label (European Union flower label), Angel (Canadian environmental selection protection label), Japan (ecological symbol of Japan).

The second type is the label of self declaration. They either examine the whole life cycle of the product or examine the ecological performance of the product in a certain way, mainly developed by some industry associations or non-governmental organizations. It does not emphasize testing by third party laboratories or directly audited on the spot, and some even allow manufacturers to declare themselves. For example: Oeko-Tex Standard 100 (ECO textile standard 100), Milieukeur logo (Holland ecological symbol), Toxproof Seal (German eco textile logo), Eco-Tex (German eco textile logo), Gut (German carpet eco label), Bioland and Demeter (ECO label established by NGOs).

Third types: the declarations and reports of environmental behavior are non selective and are the buyers' standard of buyers, but they are in line with the standards, regulations, and decrees of the sale of the products. For example, Clean Fashion logo and Comitextil logo.

In so many eco textile standards and labels, the Oeko-Tex Standard 100 and Europen Eco-Label are more influential than others. At the same time, we should pay attention to the ecological standard Oeko-Tex Standard 100 is voluntary, and it is not necessary to meet its assessment indicators to sell in the EU market. If its assessment index is reached, products can enter the more high-end circulation field, the added value of products can be improved; and the products that fail to meet their assessment criteria can not be linked to the standard and label, will enter the lower end of the circulation field, the added value of the products will be much lower, of course, such products must also meet buyers' requirements to enter the EU market.
