Abstract

A semi-absorbent, semi-resistant, breathable fabric includes a single-layer having a first, hydrophilic side that absorbs water, and a second, hydrophobic side; wherein the first, hydrophilic side of the single-layer fabric quickly spreads out a liquid that is absorbed laterally to a wider area such that the absorbed liquid does not seep or pass through to the second, hydrophobic side of the single-layer fabric under gravitational force. A method of making a semi-absorbent, semi-resistant, breathable fabric includes: subjecting a first side of a single-layer fabric to a hydrophilic amino functional polysiloxane softener; treating a second opposite side of the fabric with a fluorocarbon compound under low pressure such that the fluorocarbon compound penetrates no more than half of the fabric thickness; and drying and curing the fabric, preferably at a temperature of about 145° C. to 155° C. for about three minutes to about five minutes.

First claim

1 - 15 . (canceled)

16 . A mattress pad, comprising:
(a) a single layer of fabric; (b) a layer of wadding; and (c) a nonwoven fabric defining an enclosure in which the wadding is contained; (d) wherein the single layer of fabric comprises a hydrophilic side and an oppositely facing hydrophobic side, with the single layer of fabric being stitched to the enclosure in covering relation to a top side of the enclosure, and with the hydrophilic side of the single layer of fabric facing away from the enclosure and the hydrophobic side facing the enclosure, whereby liquid that is absorbed by the hydrophilic side of the single layer of fabric on the top side of the mattress pad spreads across the hydrophilic top side of the mattress pad and does not seep through to the hydrophobic area of the single layer of fabric or to the wadding layer.

17 . The mattress pad of claim 16 , further comprising a skirt fabric or edge fabric stitched to the enclosure.

18 . The mattress pad of claim 16 , wherein the single layer of fabric comprises a breathable, woven fabric comprising warp and weft yarns, each of the yarns including at least a first extent that is hydrophilic and at least a second extent that is hydrophobic relative to the first extent.

19 - 28 . (canceled)

29 . A mattress pad, comprising:
(a) a single layer of fabric; (b) a layer of wadding; and (c) a nonwoven fabric defining an enclosure in which the wadding is contained; (d) wherein the single layer of fabric comprises a semi-absorbent side and a semi-resistant side, the two sides defining a single layer of the fabric, wherein each side has a respective depth, with the combined depths of the sides defining the thickness of the single layer of fabric, and wherein a gradient exists with respect to water absorbency properties along the thickness of the single layer of fabric.

30 . The mattress pad of claim 29 , wherein for each said yarn, alternating extents thereof are hydrophilic and hydrophobic.

31 . The mattress pad of claim 29 , wherein each said yarn comprises natural fibers, synthetic fibers, regenerated fibers, or combination thereof.

32 . The mattress pad of claim 29 , wherein the single-layer fabric is knitted.

33 . The mattress pad of claim 29 , wherein the single-layer fabric is woven.

34 . The mattress pad of claim 33 , wherein the single-layer fabric is woven from weft yarns and warp yarns, each of which has a uniform absorbency along its length, the hydrophilic and hydrophobic properties being imparted to the single-layer fabric after the fabric has been woven.

35 . The mattress pad of claim 29 , further comprising a skirt fabric or edge fabric stitched to the enclosure.

36 . A mattress pad, comprising:
(a) a single layer of fabric; (b) a layer of wadding; and (c) a nonwoven fabric defining an enclosure in which the wadding is contained; (d) wherein the single layer of fabric comprises a fabric construction of yarns extending on and collectively defining first and second opposite sides of the single-layer fabric, wherein for each said yarn, an extent thereof extending on and defining part of the first side of the single layer of fabric is hydrophilic, and an extent thereof extending on and defining part of the second side of the single layer of fabric is hydrophobic.

37 . The mattress pad of claim 36 , wherein for each said yarn, alternating extents thereof are hydrophilic and hydrophobic.

38 . The mattress pad of claim 36 , wherein each said yarn comprises natural fibers, synthetic fibers, regenerated fibers, or combination thereof.

39 . The mattress pad of claim 36 , wherein the fabric is woven.

40 . The mattress pad of claim 39 , wherein the single layer of fabric is woven from weft yarns and warp yarns, each of which has a uniform absorbency along its length, the hydrophilic and hydrophobic properties being imparted to the single-layer fabric after the fabric has been woven.

41 . The mattress pad of claim 36 , further comprising a skirt fabric or edge fabric stitched to the enclosure.

42 . The mattress pad of claim 16 , wherein the single layer of fabric comprises a breathable, woven fabric comprising warp and weft yarns, each yarn comprising alternating extents that are hydrophilic and hydrophobic.

43 . The mattress pad of claim 16 , wherein the single layer of fabric comprises a breathable fabric of woven yarns, each yarn comprising natural fibers, synthetic fibers, regenerated fibers, or combination thereof.

44 . The mattress pad of claim 16 , wherein the single layer of fabric is knitted.

45 . The mattress pad of claim 16 , wherein the single layer of fabric is woven from weft yarns and warp yarns, each of which has a uniform absorbency along its length, the hydrophilic and hydrophobic properties being imparted to the single layer of fabric after the fabric has been woven.
