15Th Anniversary Special Issue: Environmental Protection Textile Development Wisdom Future

Ceng Xiang, a textile expert in Hongkong, began to engage in textile work in 1971, and gradually realized the damage to the environment and people's health caused by the textile dyeing and printing industry. Since 2003, a group of textile and IT professionals have been convened to upgrade the technology and management methods of textile industry, and develop new textile fibers, fabrics, functional clothing and management system software.

In 2008, Mr. Zeng Xiang held the new high-tech textile technology conference in Dongguan, and released new textile technology such as plasma dyeing technology, straw pulp fiber, microcapsule flavor technology, Xiao Xing new functional fiber and so on. Nearly 1000 textile industry participants attended the meeting, and leaders from many provinces and cities delivered speeches at the scene.

The cotton fiber cationic modified pollution-free dyeing technology developed by Mr. Zeng Xiang in 2015 has changed the dyeing process of traditional cotton fabrics, breaking the drawbacks of using more chemical additives and heavy pollution in traditional cotton dyeing. No salt, no alkali and continuous dyeing were achieved. The dyeing depth increased by more than 80%, and the color fastness reached over 4.5. At the same time, 50% of the energy was saved, 80% of water was saved, 25% of -35% and 25% of pollutant discharge were saved, and the working efficiency was increased by 40-50%.

The undyed bionic cotton (COTTON-SIM) product developed by the team in 2017 made the finished product and accepted the market order.

In recent years, Mr. Zeng Xiang has led the team to promote the existing non pollution dyeing technology modified products, bionic cotton fabrics, environmental health products, waterproof and wrinkle resistant functional products, and has also developed a healthier, more environmentally-friendly product with coloured soft drink beverages (orange juice, cola, red / green tea, etc.), BIO-DYE, life care and dyeing, printing and dyeing of tea and red wine, etc.
