A dryer felt comprising a plurality of machine direction and cross machine direction yarns interwoven to provide a multiple-plane fabric having at least a base plane, a top plane and an intermediate plane positioned between the base plane and the top plane. The base plane is defined by a first plurality of cross machine direction yarns, the top plane is defined by a second plurality of the cross machine direction yarns, and the intermediate plane is defined by a third plurality of the cross machine direction yarns. In one embodiment, encapsulated stuffer yarns constituted the third plurality of the cross machine direction yarns. In another embodiment, encapsulated filling yarns constitute the third plurality of the cross machine direction yarns. In all embodiments, each of the encapsulated yarns comprises a straight, twistless monofilament core and a close-fitting encapsulating sheath surrounding the full length of the core.
A dryer felt comprising:
A method of making a dryer felt having encapsulated, bulky center yarns, the method comprising the steps of:
A dryer felt having a face surface and a back surface, said dryer felt comprising:
A method of making a dryer felt having a face surface, a back surface, and encapsulated, bulky center yarns, the method comprising the steps of weaving a plurality of machine direction and cross machine direction yarns into a multiple-plane fabric to provide at least a base plane, a top plane and an intermediate plane positioned between said base plane and said top plane, said base plane being entirely defined by a first plurality of said cross machine direction yarns, said top plane being entirely defined by a second plurality of said cross machine direction yarns, and said intermediate plane being defined entirely by a third plurality of said cross machine direction yarns, only said third plurality being encapsulated yarns, each of said encapsulated yarns comprising a monofilament core and an encapsulating sheath surrounding the full length of said core, said sheath defining a soft, bulky outer surface which, when woven into said fabric, acts to prevent shifting of said encapsulated yarns in said fabric, wherein said encapsulated yarns reduce fabric permeability and add bulk to the fabric while contributing to fabric stability, said machine direction yarns being interwoven with said first plurality of cross machine yarns to define said back surface on said base plane and interwoven with said second plurality of cross machine direction yarns to define said face surface of said top plane.
