Abstract
A touch-fastening anti-skidding warp knitted fabric (10, 10a) comprising a foundation layer (40) that has wales (A, A1, A2, B1, B2. B3) of the fabric (10, 10a) that comprise pliable base yarns (30a, 30b) and a plurality of discrete synthetic filaments (20a, 20b) knitted together. Each stitch of the synthetic filaments (20a, 20b) is looped around a previous stitch of the filament in the same wale and is subsequently cut to form a discrete length of the filament (20a, 20b) that comprises a "U" shaped loop (21) in the foundation layer (40) and two legs (22) projecting from the foundation layer (40) by a predetermined distance which are used to constitute hooks (22). The Fabric may incorporate apertures (X) or may be in a planar form without aperture.
Claims (17)
1. A touch-fastening anti-skidding warp knitted fabric comprising a foundation layer that has wales of the fabric that comprise pliable base yarns and a plurality of discrete synthetic filaments knitted together, wherein each stitch of the synthetic filaments is looped around a previous stitch of the filament in the same wale and is subsequently cut to form a discrete length of the filament that comprises a loop in the foundation layer and two legs projecting from a surface of the foundation layer.
2. A fabric according to claim 1 wherein the synthetic fibres are monofilaments selected from the group of synthetic materials consisting of polyamides, polyesters, polypropylene, and polyethylene.
3. A fabric according to claim 1 or claim 2 wherein the synthetic filaments each have a diameter in the range of 0.02mm to 0.5mm.
4. A fabric according to any one of claims 1 to 3 wherein the filaments have a Shore hardness of between 35A to 90A or between 40D to 90D.
5. A fabric according to any one of claims 1 to 4 wherein the pliable yarns are natural or synthetic spun yarns selected from the group consisting of acrylic, cotton, cellulose, polyester, and blends of these fibres.
6. A fabric according to any one of claims 1 to 5 wherein successively, the pliable yarns and the the loops that are extended transversely to an adjacent wale of the fabric.
7. A fabric according to any one of claims 1 to 6 wherein the foundation layer comprises a fabric having apertures in the foundation layer.
8. A fabric according to any one of claims 1 to 6 wherein the foundation layer does not have apertures knitted into its structure.
9. A fabric according to claim 7 wherein the shape of the apertures is selected from the group consisting of polygonal, circular, hexagonal, rectangular, and quadrangular.
10. A fabric according to any one of claims 1 to 9 wherein at least the tips of the legs are subjected to heat to melt the ends of the legs and thereby form hooks.
11. A fabric according to claim 10 wherein the tips of the legs are deformed to form hooks
12. A method of warp knitting a touch fastening fabric having entangling means for engaging loops or entangling structure of another structure according to any one of claims 1 to 9, the method comprising the steps of:
(a) Simultaneously warp knitting a plurality of continuous lengths of pliable yarns together with a plurality of continuous lengths of synthetic monofilaments on a double needle bed warp knitting machine to form two foundation layers each of which is knitted on one of the needle beds and has wales of the fabric that have the stitches of the synthetic filament linked together along the wale with wales of the foundation layers linked along and between the wales by the pliable yarns, and wherein the two foundation layers are linked together by stitches of the synthetic filaments that extend between the two foundation layers; and (b) Cutting the stitches of the synthetic filaments that extend between the foundation layers to form two separate fabrics each of which has a foundation layer with discrete lengths of the filaments that have a loop linked to the next stitch of the filament along each wale of the foundation layer and two legs projecting from the foundation layer.
(a) Simultaneously warp knitting a plurality of continuous lengths of pliable yarns together with a plurality of continuous lengths of synthetic monofilaments on a double needle bed warp knitting machine to form two foundation layers each of which is knitted on one of the needle beds and has wales of the fabric that have the stitches of the synthetic filament linked together along the wale with wales of the foundation layers linked along and between the wales by the pliable yarns, and wherein the two foundation layers are linked together by stitches of the synthetic filaments that extend between the two foundation layers; and (b) Cutting the stitches of the synthetic filaments that extend between the foundation layers to form two separate fabrics each of which has a foundation layer with discrete lengths of the filaments that have a loop linked to the next stitch of the filament along each wale of the foundation layer and two legs projecting from the foundation layer.
13. A method according to claim 12 wherein the knitting process is commenced by knitting pairs of adjacent wales together with the pliable yarn passing from one wales to the next of the wales of the pair.
14. A method according to claim 12 or claim 13 wherein the wales of the foundation layer is knitted by passing the pliable yarns between adjacent wales of the foundation layer.
15. A method according to any one of claims 12 to 14 wherein the apertures in the foundation layer are formed by knitting a set of first pairs of wales, splitting each of the first pairs of wales into two wales and passing the pliable yarns to an adjacent one of the wales of each split first pair of wales and knitting the wales together to form a second set of pairs of wales, splitting the second pairs of wales into two wales and passing the pliable yarns to an adjacent one of the wales of each split second pair of wales and knitting the wales together to re form the set of first pairs of wales and thereby define apertures in the foundation layer between the wales.
16. A method according to any one of claims 12 to 15 wherein at least the tips of the legs are subjected to heat to melt the tips and thereby form hooks.
17. A method according to claim 16 wherein the tips are the legs are deformed to form hooks.
