Abstract
A stitch bonded fabric sheet (10) has a felt web (12) with hydrophobic layer (14) and a hydrophilic layer (16) stitch bonded with yarns (18) to create yarn faces (24 and 26) over the respective outer surfaces (20 and 22) of the felt web (12). Sheet (10) may be used as a fluid-retention fabric such as to replace the facing fabric and felt layer in an incontinent pad.
Claims29
A stitch bonded facing fabric comprising:
- a first layer of hydrophobic felt;
- a second layer of hydrophilic felt being adjacent to the first layer so as to define a felt web having an upper surface defined by an upper side of the first layer and a lower surface defined by a lower side of the second layer;
- and
- a plurality of stitch bonding yarns repeatedly extending through the felt web with yarn segments extending across both the upper and lower surfaces of the felt web such that the yarn segments extending across the felt web upper surface cooperate to form a top yarn face above the felt web upper surface and the yarn segments extending across the felt web lower surface cooperate to form a bottom yarn face below the felt web lower surface.

A stitch bonded facing fabric comprising:
- a felt web having a hydrophobic upper aspect extending from an upper surface of the web and a hydrophilic lower aspect extending from a lower surface of the web;
- and
- a plurality of stitch bonding yarns repeatedly extending through the felt web with yarn segments extending across both the upper and lower surfaces of the felt web such that the yarn segments extending across the felt web upper surface cooperate to form a top yarn face above the felt web upper surface and the yarn segments extending across the felt web lower surface cooperate to form a bottom yarn face below the felt web lower surface.
A fluid-retaining fabric comprising:
- a stitch bonded facing fabric having a first layer of hydrophobic felt, a second layer of hydrophilic felt being adjacent to the first layer so as to define a felt web having an upper surface defined by an upper side of the first layer and a lower surface defined by a lower side of the second layer, and a plurality of stitch bonding yarns repeatedly extending through the felt web with yarn segments extending across both the upper and lower surfaces of the felt web such that the yarn segments extending across the felt web upper surface cooperate to form a top yarn face above the felt web upper surface and the yarn segments extending across the felt web lower surface cooperate to form a bottom yarn face below the felt web lower surface;
- and
- a barrier layer attached to the bottom yarn face.
