Environmental Issues: Overview of Hazardous Substances

Over the past few years, under the impact of global “green consumption”, clients and consumers worldwide have actively sought development of green textiles which are green products that are beneficial to the environment. Therefore, manufacturers must closely follow the environmental protection trend of the world and continue to improve their manufacturing processes and product design so as to ensure their products are both highly functional and safe for the environment.

Currently, hazardous chemicals are divided into three classes based on the specifications: Oeko-Tex Standard 100, control documents of brand-exclusive hazardous substances, and bluesign®.


  • Oeko-Tex Standard 100

    The safety testing for textiles in the industry currently includes relating accessories such as fabric, feather and buttons and the test is usually conducted by following the Oeko-Tex Standard 100 which is proposed by the Hohenstein Research Institute and the Austrian Textile Research Institute in 1992 for examination of the residues of hazardous substances in textiles and clothing.

  • Control documents of brand-exclusive hazardous substances

    Following report is used as an example and it shows the testing requirements for Adidas’ down products and the down products that are subjected to fine wash and meet the requirements of bluesign® for use safety can pass the following items, e.g. heavy metals, pH, chlorophenols, pesticides, formaldehyde, organic tin, and APEO. Most brands will develop brand-exclusive control documents to ensure the final product can protect consumer safety.

  • bluesign®

    Kwong Lung is the first down processing plant in the world to be certified by bluesign®. The certification indicates constant and positive action of the overall environment of the plant, including consumer safety, environmental protection and labor protection. For example, improvement of the working environment in the plant, labor safety, addition of personal protection equipment, safety assessment of chemical agents and use, increase of the use rate for water recycle system, attention to product safety, eco-friendly and humane, as well as being a leader and maintaining good standing as a socially responsible corporation.
