Napped sheet having a pattern thereon and method for its production

摘要

A napped sheet has a pattern thereon formed by the sharp contrast between an area with a nap surface and an area with a reversed nap surface on which nap ends are reversed and extend into the inner part of the sheet. A process for producing the sheet includes the step of first raising a fiber sheet and next impinging a high-pressure columnar fluid jet stream on part of the fiber sheet. The product of the invention is soft, strong and beautiful, and has good durability. The production process is simple and inexpensive.
