| 发明名称 | Pilling-resistant artificial leather | ||
| 摘要 | An artificial leather is provided having a raised nap to give an elegant appearance, and further has a good pilling-resistance without affecting the spinning performance. The pilling-resistant artificial leather is a sheet-form object including a microfiber having a monofilament diameter of 0.3 to 10 μm and a polymeric elastomer, and having a raised nap made of the microfiber. The microfiber includes inorganic particles in a proportion of 0.01 to 5% by mass relative to 100% by mass of the microfiber, and a silicone oil in a proportion of 0.001 to 1% by mass relative to 100% by mass of the microfiber. The microfiber contains a polyester microfiber in a proportion of 90% by mass or more thereof. | ||
