Silicone oil in the fashion industry's' technological aesthetics': from smart fabrics to 3D printed shoe materials as a 'liquid designer'

Traditional fabrics have a single function, but the composite material of silicone oil and shape memory polymer is overturning this cognition: by regulating the length of silicone oil molecular chains, smart fabrics that can reversibly deform in the range of 25 ℃ to 60 ℃ can be prepared. The "temperature controlled windbreaker" launched by a certain sports brand adopts this technology: when the ambient temperature rises, the silicone oil molecules on the surface of the fabric expand to form breathable pores, increasing the heat dissipation efficiency by 40%; When the temperature decreases, the pores close and the insulation performance is enhanced by three times. In the field of shoe materials, silicone oil-based photosensitive resin has brought revolutionary breakthroughs to 3D printing: its printed sole midsole combines high elasticity (rebound rate of 78%) and low density (0.2g/cm ³), and can achieve precise control of hardness from 30 Shore C to 80 Shore C by adjusting the silicone oil content. Adidas' latest "Futurecraft 4D" running shoe adopts this technology, and its 3D printed midsole can adjust its structure in real time according to the pressure distribution of athletes' feet, reducing the risk of sports injuries by 27%.
