Also, on Friday, Invista Nylon Chemicals (China) Co announced plans to establish its new Asia innovation center in Shanghai at SCIP.

The project has an investment of more than 95 million yuan ($15 million), which is the company's first research and development center for specialized nylon development in Asia.

It is regarded as the company's next milestone in growing its specialized nylon value chain in China to allow it to better meet evolving customer demand across the region.

"The China market plays an increasingly important role in Invista's global business, and the plan to establish the Asia innovation center in Shanghai is a clear example of our commitment to further meeting strong local and regional demand for high-quality nylon products as China is also expected to become the world's largest nylon consumer," said Pete Brown, Invista's executive vice-president of nylon polymer.

Located near Invista's integrated nylon 6,6 facility in SCIP, the lab will promote the company's comprehensive nylon 6,6 capabilities in China, including R&D, production, sales and technical services, to provide customers with superior quality nylon products and solutions.

The polymers and fibers arm of Koch Industries said the new plant, which will be completed in 2022, will help meet the growing demand for nylon 6,6 chemical intermediates in China and the Asia-Pacific region.

ADN is an intermediate chemical used in the production of nylon 6,6.

"When complete, the Shanghai facility will be the largest integrated nylon 6,6 manufacturing facility in the world," said Gentry.

Nylon 6,6 products are widely used in automobile, electrical and electronic industries, as well as consumer and industrial applications.

Invista expects China to be the world's largest consumer of nylon in the coming years, and said it was looking to serve China from China to realize the full potential of the downstream market, said Kyle Redinger, vice-president of nylon intermediates for the Asia-Pacific region at Invista.

During the show, Peacebird's women's unit combined the classic magic of the Harry Potter IP, and displayed some items like black shawls, classic plaid trousers and nylon berets.

The facekini, a nylon mask designed for swimmers and beachgoers which covers the head and reveals only the eyes, nose and mouth, is popular among residents in Fujian province on China's eastern coast.

At the booth of Zhejiang Jiaxin Silk Corp Ltd, a regular participant in the fair for over 30 years, Wu Huiping passionately introduced their new textile product crafted by interweaving collagen-modified nylon fiber with silk.

Citing a rapid increase of the number of local nylon materials companies, Wen Zhanbin, Party chief of Shantou, said the textile and clothing industry has entered a new phase of green and smart development.

The city has only one enterprise in the production of nylon materials, with a production capacity of only 17,000 metric tons.

The local production of nylon materials will be expanded to 400,000 tons in the next two years, with the establishment of four to five such new companies.

"Expansion of the production of nylon materials has fully demonstrated confidence from local textile and clothing businesses, with more funds being invested in the industry," said Wen.

"Textile makers in China have already begun to adopt renewable energy sources, environmentally friendly textile materials including biomass fiber and recycled substances to make the whole production process pollution free, as well as cut dependence on crude oil when producing common synthetic materials such as nylon or polyester," he said.

The product, called Super Pouch Solution, uses layered battery cells, which are encompassed by a cast polypropylene film, an aluminum foil, and a nylon film.

The company prints 3D products for construction, medicine, automobiles and other fields, using more than a dozen materials such as resin, nylon, stainless steel and aluminum alloys.
