AI Technical Summary
Pure TPU leather has poor skin-friendliness, a sticky and stiff feel, and insufficient resistance to sweat corrosion and aging. It is difficult to meet the comfort and long service life requirements of high-end leather products. Existing modification schemes cannot simultaneously improve the material's skin-friendliness, softness, sweat resistance, anti-aging properties, and mechanical structural stability.
TPU leather modified by organosilicon graft copolymerization is used. Combined with the optimization of molding process, organosilicon modified TPU particles are prepared by blending organosilicon modifier and composite auxiliaries, and then plasma surface skin-friendly treatment is performed to form a one-piece seamless leather.
It improves the elasticity, skin-friendliness, sweat resistance, and anti-aging properties of TPU leather, solves the problems of traditional TPU leather such as hard touch, stickiness, and yellowing, extends service life, and is suitable for the large-scale production of high-end leather.
