Beijing 2022 Winter Olympics will bring people a surprise to people. From the opening ceremony to the podium, from the venue to Dong'ao Village, it has demonstrated the latest achievements in my country's textile industry technology, fashion, and green development, and people are exciting. Now, we will make our textile fashion and "black technology" at the Winter Olympics, and experience the highlight of the Winter Olympics in the textile industry.

Torch ribbon and awards bouquet "weaving" new intentions

The Olympic Torch is one of the elements of the previous Olympic Games. The torch "flying" in this Winter Olympics is uniform. The Professor of Donghua University, the head of the Textile Science and Technology Innovation Center, Sun Ye, as a key manufacturing technology provider of the torch, an important part of the ribbon (shell), and the "big" learning of the "small" torch behind.

The three-dimensional spherical three-dimensional knitting machine developed by the Sun Yizhu team. The Torch "Flying" Production Scene in Huai'an Production Base in Jiangsu Province.

Sun Yizhu used "high-tech materials, high-tech, high-end manufacturing", and summarized the perfect collision of torch art design and technology innovation. The torch "flying" outside the flora is very special, is a high dimensional face, which is an extremely complex shaped structure for engineering manufacturing. In August 2020, the Torch General's assumes that Shanghai Petrochemical found Sun Yizhu with nearly 20 years of experience in the automatic weaving equipment, seeking how to use carbon fiber composites to presen a high precision of the torch ribbon art shape.

Sun Yizhu said that it is necessary to convert manual muddy torch works into digital manufacturing, industrially produced products, and weave it with high-tech carbon fiber composites, first break through mathematical modeling difficulties. Only by mathematical modeling can high precision to vivid the art design of the restore work, making automated digital manufacturing. To this end, he led the team several times with the Torch Foreign Designer Team of the Central Academy of America, and the staff of the Winter Olympics group related staff, etc., modified, and polished. In the production workshop of Huai'an, Jiangsu, a 10-meter diameter ring device is running at high speed, thousands of black silk beams are interweaving, and at first glance is like "weaving", only count Minutes, you can "weaving" out of the torch coat of accurate to grams. Sun Yizhu introduced that the flare ribbon is variable, the curvature, the curved thickness is not consistent, and the traditional manufacturing process cannot be realized. He revealed that this huge ring equipment is "secret weapon" of "weaving" torch coat, exclusive development of Donghua University, the world's first large-scale heterogeneous structural piece 3D high precision spherical stereo braided machine, the series of knitting machines Weaving aircraft, high-size structural support parts, also knitting screw, drone, flare ribbon, etc. precision shaped structural parts.

In order to let the carbon fiber composites in the industrial production of the soft and beautiful, Sun Yizhu leads the team invented the "eccentric" weaving method, solved the big curvature, variable density weaving problem; original double robot coordinated clamping core mode control algorithm To ensure that large-size shaped structural parts are optimal in complex strategies; developed single-yarn tension full-process digital regulation technology, achieving constant tension accurate weaving; research and development of high-dimensional surface automatic polishing skills operation robot system. The three-dimensional automated three-dimensional knitting and automation grinding of the torch lever is realized. The project technology not only fills the domestic gap, but also in the international position.

The highlight of textiles is also present on the Awards award ceremony. When the award athlete was awarded, the colorful, and the shaped awards bouquet also included in people's eyes, but this is not ordinary flowers bouquet. The Winter Olympics and the Winter Disabled Awards awards 1251 bouquets. In order to reflect the green Olympics, the bouquet of this Winter Olympics has been boldly innovative, and the Shanghai Intangible Cultural Heritage Representative Project "Haipai Farpline Skills" has been hand-made, and the "Haipai Farpline Skating Skills" Inheritance Unit Hengyuanxiang Group . Personnel participating in the crochet come from difficult families and disabled populations. The cashmeral bouquet is warm and "never daddy", which has retained the shape of the bouquet in the Olympic award ceremony, and practiced the green office of Olympics.
