Why is it difficult to make nonwoven fabrics?

According to the reporter's understanding, at present, China's development and application of non-woven fabrics for outdoor clothing is almost zero. Xu Pu, honorary president of the China Industrial Textiles Industry Association, said when he talked about this issue: "We started researching nonwoven fabrics a few years ago and introduced them in several spunbond sessions, but currently There are very few domestic ones. I know that Dalian Huayang and Huaneng are doing research in this area.” Xu Pu said that the progress of foreign research in this study is representative of Germany’s Freudenberg. The company produces spunlace spunbonded nonwoven fabric under the trade name Evolon. It is a fine-denier filament which is a composite spun-bonded filament web which is continuously impacted by a high-pressure water needle to split the filament into different deniers (0.05~2.5dtex). It has excellent mechanical properties, high moisture permeability and breathability, and soft handfeel. After finishing the surface of the product, like ordinary woven fabrics and knitted fabrics, it can be washed many times and has excellent drape performance. The products include T-shirts and sportswear.

The reporter dialed the mobile phone of General Manager Zeng Shijun of Dalian Huayang Chemical Fiber Engineering Technology Co., Ltd. He told reporters that the two-component spunbond spunlace nonwovens project is a scientific research project initiated by the National Development and Reform Commission. The project is supported by the national textile special fund. Product applications include leather base fabrics, wipes, filter materials, and more. The research technology of this subject has been awarded. At present, it is mainly looking for technical partners. “We have installed 3 production lines in Guangdong. It is difficult for us to reinvest in this company. The research and development expenses of the NDRC are far from enough,” he said.

It is understood that the world can produce such special clothing fabrics in Germany, the United States and the United Kingdom. Because the non-woven fabric material has good tear resistance, light weight and soft hand feeling, it can be processed by high-tech such as ultrasonic stitching or laser cutting, so it is especially suitable for home textiles, casual clothes, sportswear, etc. It is fully qualified for outdoor equipment. This high-tech product, its micro-system technology is suitable for future high-tech clothing, is an ideal ecological fabric for making sportswear, and has a broad market prospect.

Where is our gap?

When talking about this issue, Li Guimei, deputy secretary-general of the China Industrial Textiles Industry Association, said that as a clothing fabric, the first thing to consider is its selling point. Compared with the existing knitted and woven fabrics, non-woven fabrics have different characteristics in terms of color and washability. Printing and dyeing is unstable and the price is too high, which affects its promotion. "The batch size is small, the printing and dyeing enterprises do not take orders, the bulk is large and there is no market, and the sales are not going out, so the company is not willing to do it," she said.

Xie Ming, deputy director of the Nonwovens Professional Committee of the China Textile Engineering Society and general manager of Guangzhou Kelun Industrial Co., Ltd., believes that disposable medical protective clothing and adult incontinence products are used in large quantities and at low cost. The non-woven outdoor equipment has high technical content, large investment, small quantity, and has a market but a small share. He said that there have been companies in the country that use stitch-bonded non-woven fabrics to make garment fabrics. They are similar in appearance and feel to traditional textiles, unlike typical non-woven fabrics. Can be used to make suits, jackets, coats, fur coats and other outerwear. But probably because of the high price, there is no sales, and later I have not heard of it.

China's development of non-woven fabrics for external use is still in its infancy, and its technology and products are not in the same breath as foreign countries. Today, composite nonwovens are in the ascendant. From a global perspective, the penetration of various nonwoven processes into each other and the development of hybridization and compounding has become a very obvious trend in the development of current nonwoven technology. Ultra-fine, bicomponent fibers, combined application technology, and high-tech equipment will create a beautiful blueprint for nonwoven fabrics for apparel. Just as Guo Hexin, the honorary president of the China Industrial Textiles Industry Association's spunbond non-woven fabrics branch, predicted: “It is not a dream to make clothes with non-woven fabrics. It is entirely possible! If it is made, it will give us this resource shortage. How much contribution does the country bring!" Non-woven fabrics make wedding dresses for clothing, not only because it saves energy and reduces costs, but it also brings about a revolution in garment production and design. This is something that the clothing industry is looking forward to. (Zhang Maijian)
