Abstract
Abstract ©7 A dimensionally-recoverable fabric having an angled or branched hollow region woven therein. The fabric may have conductive fibres by means of which it exhibits electromagnetic screening. Alternatively, or additionally it may have heat-softenable or hot-meltfibres such that it becomes impermeable or is capable of bonding to a substrate on heating.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
15 words
A heat-activatable article comprising a fabric having an angled or branched hollow region woven therein.
Claim 2
Dependent Claim
15 words
A heat-activatable article comprising a fabric having an angled or branched hollow region woven therein.
Claim 3
Dependent Claim
12 words
An article according to claim 1,in which the fabric comprises heat-recoverable fibres.
Claim 4
Dependent Claim
24 words
An article according to claim 1 or 2, in which the fabric comprises conductive fibres by means of which the fabric exhibits electromagnetic screening.
Claim 5
Dependent Claim
34 words
An article according to any preceding claim, in which the fabric comprises heat-activatable fibres such that the fabric becomes impermeable or is capable of bonding to a substrate on heating or becomes substantially rigid.
Claim 6
Independent Claim
193 words
A method of making a heat-activatable article comprising a fabric having a hollow region woven therein from fibres comprising heat-activatable fibre, which comprises; at least notionally splitting a zone of warp fibres into at least a first group of fibres and a second group of fibres, such that the fibres of the first group alternate regularly or irregularly with those of the second group; inserting weft fibres (a) to interlace warp fibres of the first group but not of the second group, and inserting weft fibres (b) to interlace warp fibres of the second group but not of the first group, thus causing two layers of fabric to be woven; and either (i) inserting said weft fibres (a) and (b) into warp fibres which border said zone, thus providing a join between the two layers or (ii) providing weft fibres (a) and weft fibres (b) as a continuous running weft, or (iii) providing a knitted stitch joining said two layers; the number of said groups of fibres,or the number of fibres within at least one of the groups varying in the warp directon such that an angled or branched hollow fabric is produced.
Claim 7
Independent Claim
193 words
A method of making a heat-activatable article comprising a fabric having a hollow region woven therein from fibres comprising heat-activatable fibre, which comprises; at least notionally splitting a zone of warp fibres into at least a first group of fibres and a second group of fibres, such that the fibres of the first group alternate regularly or irregularly with those of the second group; inserting weft fibres (a) to interlace warp fibres of the first group but not of the second group, and inserting weft fibres (b) to interlace warp fibres of the second group but not of the first group, thus causing two layers of fabric to be woven; and either (i) inserting said weft fibres (a) and (b) into warp fibres which border said zone, thus providing a join between the two layers or (ii) providing weft fibres (a) and weft fibres (b) as a continuous running weft, or (iii) providing a knitted stitch joining said two layers; the number of said groups of fibres,or the number of fibres within at least one of the groups varying in the warp directon such that an angled or branched hollow fabric is produced.
Claim 8
Dependent Claim
20 words
A heat-activatable article comprising a woven fabric having recovery localized along or different extents of recovery along, the warp direction.
Claim 9
Dependent Claim
20 words
A heat-activatable article comprising a woven fabric having recovery localized along or different extents of recovery along, the warp direction.
Claim 10
Dependent Claim
72 words
A method of making an article according to claim 8, which method employs a first group of warp fibres of lower or zero recovery and a second group of warp fibres of higher recovery, such that fibres of the first group alternate regularly or irregularly with those of the second group, the warp fibres with which the weft interlaces changing along the warp direction from one of said groups to the other.
Claim 11
Independent Claim
43 words
A method of protecting or holding a substrate comprising a cable or cable splice which comprises surrounding the substrate by a heat activatable article comprising a fabric having a hollow region woven therein which hollow region corresponds to the configuration of the substrate.
Claim 12
Independent Claim
43 words
A method of protecting or holding a substrate comprising a cable or cable splice which comprises surrounding the substrate by a heat activatable article comprising a fabric having a hollow region woven therein which hollow region corresponds to the configuration of the substrate.
Claim 13
Dependent Claim
24 words
A method according to claim 8, in which the fabric has an electrically conductive component by means of which the fabric provides electromagetic screening.
Claim 14
Dependent Claim
27 words
A method according to claim 8 or 9, in which the fabric is recoverable and the method additionally comprises recovering the fabric into engagement with the substrate.
Claim 15
Dependent Claim
16 words
A method according to claim 8,9 or 10, in which the substrate is branched or angular.
