Practice sustainable development concept "green fiber" industrial chain certification started

Standard to advance the scientific and advanced nature

"Green fiber" is an authoritative concept put forward by the China Chemical Fiber Industry Association. Before this, "green fiber" only existed in the workshop discussion of the textile chemical fiber circle, and there was no accurate, clear and professional definition.

In March 2016, registered by the State Administration for Market Supervision and Administration, the China Chemical Fiber Industry Association launched the chemical fiber green fiber certification work, with the Department of Consumer Goods Industry of the Ministry of Industry and Information Technology as the guiding unit. This work not only defined "Green Fiber" but also designed the green fiber logo - GF engraved on green leaves, conveying the chemical fiber industry's green commitment to humanity. The launch of green fiber certification aims to implement the new development concept of national innovation, coordination, green, open and sharing, accelerate the green process of chemical fiber industry, and realize the sustainable development of chemical fiber and textile industry.

The technical support and basis behind green fiber certification is the standard, specifically the "Green Fiber Evaluation Technical Requirements", which is a group standard issued by the China Chemical Fiber Industry Association, first released in 2018, and revised in 2019. At present, there are similar international standards and certifications in the field of green textiles and ecological textiles, so what are the characteristics and advantages of green fiber certification standards? At this press conference, Zhao Qingzhang, senior consultant of green fiber certification and chairman of ISO/TC38 textile Standard Committee, studied the above content.

Zhao Qingzhang pointed out that the revised "Technical Requirements for Green Fiber Evaluation" (T/CCFA 02007-2019) in 2019 classified the quality attribute indicators of green fiber, and further clarified the limited substances and limited values. The quality attribute is the innovation of the current version of "Requirements". The standard lists 12 variety attribute indicators and requirements for recycling chemical fibers, 14 chemical fibers for stock solution coloring, and 10 biological based chemical fibers. "For brands, these quality attributes and the limited substance content of the fiber are important indicators for their procurement," Zhao Qingzhang said.

Zhao Qingzhang compared the current standards of China's textile harmful substances limited requirements and the EU REACH regulations, the EU Eco-label eco-label, OEKO-TEX STANDARD 100, ZDHC production restricted substances list and other international more used EU related regulations and standards, he pointed out: "Green fiber evaluation technical requirements standard refers to GB18401, in the index and limit value setting, reference to the OEKO-TEX 100 standard, certification standards for fiber is also divided into three categories, that is, infant products, direct contact with skin products, non-direct contact with skin products; The certification standard refers to the standard of textiles, and limits the limited substances that may be involved in the fiber. The harmful substances produced by the dyeing and finishing process are not taken into account, which is the innovation of the standard. In addition, the certification standard is actually a collection of environmental standards, cleaner production standards and product quality standards.

Zhao Qingzhang said that in the next 40 years, the important main line of China's green low-carbon work will be carbon peak and carbon neutrality, from the perspective of green fiber certification, it is necessary to establish a measurable, reportable and verifiable evaluation method standard for certified products to determine the carbon emission value of each variety. For the category of restricted substances and the limited value and detection method, it is also necessary to learn from international standards to accurately measure the limited substances in chemical fiber, reduce the negative impact of green trade barriers, and reduce the unnecessary burden on enterprises.
