In recent years, the circular all-in-one machine has been gradually popularized, which eliminates most stitching of knitwear and enables the knitwear more well-fitting, with more delicate craft details. Together with the breathability brought by special structures of knitting, knitted sportswear is more and more popular. In addition to sportswear brands like Adidas which have knitted sportswear, luxury brands like Prada also release knitted sportswear in A/W 2019.

On the afternoon of August 23, 2019, 32 global fashion and textile giants signed Fashion Pact, set up the alliance for sustainable fashion and made solemn commitments to three themes: mitigation of climate change, restoration of biodiversity and marine protection. The signatories of this convention are famous fashion and textile enterprises, including the French luxury groups Kering, Chanel, Hermes; the Italian luxury group, Giorgio Armani; the British luxury group, Burberry; the American sportswear giant, Nike; and the Li & Fung Group in Hong Kong. RUYI GROUP, a world-renowned technology textile and fashion brand operator, is the only company in mainland China invited to sign the agreement and join the sustainable fashion alliance. So we can see the development, production and application of yarns pay more attention to the balance with nature/environment than ever. The sustainability of yarns has become the top priority.

Milano UNICA held in Shanghai Intertextile recently is an Italian fabric exhibition. Sustainable fashion becomes the hottest topic. VITALE BARBERIS CANONICO is an Italian family wool mill and the world's largest exporter of superior woolen fabrics. And it exhibits its latest achievements in sustainability: low-carbon and environmentally-friendly fabrics of H.O.P.E. series and the first sustainability report of VITALE. The houndstooth woolen overcoat under the theme of "natural colors" is made of camel hair, alpaca or Spain Moretta wool fibers. No colorants or dyestuff are used in the production, and the original color of animal hair is kept. It is in line with the opinion that natural yarns in original colors are used to make the knitwear. Therefore, the natural originality of yarns is emphasized, and noise pollution, water pollution and air pollution in wool processing is effectively reduced.
