发明名称 Dryer felt having a soft, bulky surface
摘要 A dryer felt having a soft, bulky top surface and comprising at least a top surface, which is defined by a plurality of machine direction yarns and a plurality of cross machine direction yarns interwoven according to a desired weave pattern. A preselected number of the yarns of the top surface are encapsulated yarns, the number being chosen to ensure that a major portion of the top surface is soft and bulky. Each of the encapsulated yarns comprises a straight, twistless monofilament core and a close-fitting encapsulating sheath surrounding the full length of the core.
