At the Beijing Fabrics Fair in March this year, Du Chao, president of the China National Textile and Apparel Council, emphasized during a visit to the Tianjin Tianfang Group booth that environmentally friendly fabrics should not just serve as green labels but should integrate real environmental impact data into each product. He urged the industry to focus on measurable carbon reduction indicators rather than superficial eco-friendly claims. This sentiment was echoed by many fabric companies at this year's event, as more brands are now prioritizing sustainable materials and carbon reduction metrics.
According to reports, Asahi Group has implemented several energy-saving and emission-reduction initiatives, including the use of frequency conversion technology, condensing cooling water recovery systems, hot air pipe installations in dormitory buildings, and improved dyeing methods for cotton/OP and polyester fabrics. Other projects include boiler exhaust heat recovery units, setting machine exhaust gas purification devices, and converting from heavy oil to natural gas for boilers. These efforts collectively help reduce energy consumption and save significant amounts of steam annually. For instance, frequency conversion technology alone saves 670,000 kilowatt-hours per year, while the boiler exhaust heat recovery system saves 10 tons of steam daily.
Experts recommend that the textile industry develop clear carbon reduction standards and track energy savings per meter or yard of fabric. This would provide manufacturers with clearer guidelines for reducing emissions. Meanwhile, companies like Shenzhen Awakening Clothing have been advocating for plant-based fibers and recycled materials. Mr. Jing, a company representative, explained that their products avoid animal fibers due to the environmental impact of animal agriculture, which contributes significantly to global carbon emissions.
In line with this trend, many fabric manufacturers are now focusing on natural plant fibers, with cotton-linen blends becoming increasingly popular. A linen manufacturer in Hunan noted that natural linen is now favored by both foreign buyers and domestic designers. However, there remains a strong demand for organic cotton and hemp fabrics, which are still scarce in the domestic market.
Miss Cai, a representative from Shenzhen Awakening, began searching for organic cotton fabrics in mid-2009 but has yet to find suitable suppliers. Although organic food has gained popularity, organic plant fiber fabrics remain underdeveloped in China. Recycled fabrics also face challenges due to an incomplete waste collection system.
Yang Zhaohua, vice chairman of the China Textile Industry Association, pointed out that Japan has a well-established waste classification system, including detailed categorization of recyclable and non-recyclable materials. In contrast, China’s recycling infrastructure is still developing, and improving public awareness of environmental protection is key to advancing the use of recycled textiles. (Clothing Times)
Ultrasonic Welding Non Woven Fabric
What fabrics can be ultrasonically welded?
Ultrasonic welding uses ultrasonic energy at high frequencies (20–40 kHz) to produce low amplitude (1–25 μm) mechanical vibrations. The vibrations generate heat at the joint interface of the parts being welded, resulting in melting of the thermoplastic materials and weld formation after cooling.Acrylics, acetates, polyester, nylon, polypropylene, spandex and PVC are all suitable for bonding or cutting. In general, the higher the synthetic content, the easier it is to cut and seal with ultrasonic energy.
Such as:Non Woven Filter Fabric, Polyester Non Woven, Non Woven Felt are especially suited for ultrasonic bonding.
