The designer explained the "black technology" in the "Beijing 8 minutes" performance costume.

In the closing ceremony of the Pyeongchang Winter Olympics held on the 25th, "Beijing 8 minutes" performances, the performances of "light and warm, windproof and breathable, sporty and luminous" attracted people's attention. What are their characteristics? What new materials and high technology are used? These issues have also attracted people's attention.

On the 27th, Chu Yan and Zhou Shaoen, teachers of Beijing Fashion Institute who led the team of teachers and students to complete the "8 minutes of Beijing" performance costume design work, returned to Beijing from the Pyeongchang Winter Olympics and introduced the situation to the reporter.

Chu Yan told reporters: "This performance costume has three major characteristics: one is strong cold; the second is high technology; the third is with fashion."

The performance staff often trains at an outdoor low temperature continuous rehearsal of less than 10 degrees Celsius for more than 30 minutes. The most important requirement for clothing is to keep warm. However, the performers also wear roller skates to make a series of smooth and large-scale sliding sports, which requires the clothing to be both thin and warm.

“In order to balance the lightness and warmth of the garments, we constantly try a variety of materials and use a variety of techniques, such as the use of graphene and self-heating fibers with a low-temperature sustainable heating function in the inner layer of the garment, turning passive warming into active Keep warm. Also in the middle layer filled wool flakes to meet the warmth needs. The outer layer is made of windproof and breathable nylon soft shell material." Chu Yan said.

“In order to make the clothing easy for performers to exercise, when designing, we use different materials for different requirements of heat and heat dissipation in different parts, and the thickness of the materials is also different. For example, if the underarm is not filled and the breathability is ensured, the back design focus is Considering the heat dissipation performance, the filling on the arm is focused on the boom position according to the actual feelings of the performer.” Zhou Shaoen said, “We also provide underwear and outerwear according to the difference in the body type and temperature perception of the performer. Modular choice."

In addition, the style design also reflects the high-tech and fashion sense. Two designers introduced, for example, the use of flexible LED strips, the flexible LED strips on each garment are made up of 8 wires in series, each with about 100 beads. Because the wires do not have elasticity, in order to reduce the stretching effect of the movement on the wires, the design of the LED lamp bead points is also quite elaborate: adopt a curve arrangement method, and draw a line for each lamp bead, and arrange the line to be dense according to the motion stream line. , highlighting the waist curve. Light beads are also sewn on the gloves and shoes, and the full set of clothing creates a “future fan”.
