发明名称 Multilayer sheet structure and production method thereof
摘要 A multilayer sheet structure (10) comprises a front sheet (11), a net-like backing sheet (12), and sewing threads (14) for partially joining the front sheet with the backing sheet so as to form bag portions (13) between the front and backing sheets. Paddings (15) such as cotton, wool or the like can be stuffed through net clearances of the backing sheet into bag portions surrounded with sewing threads to form bulges (11b) at desired locations on the front surface of the front sheet. Thus, a quilted multilayer sheet structure (17) having bulges on the front surface thereof can be easily produced.
