Abstract

A size-adjustable woven fabric comprises a first set of threads ( 10 a - 10 i ), each formed of a heat-shrink polymer material, at least one conducting thread ( 20 ), formed of an electrically conducting material, wherein the first set of threads ( 10 a - 10 i ) runs substantially parallel with each other, and wherein the conducting thread ( 20 ) runs substantially across the first set of threads ( 10 a - 10 i ). There is further disclosed a wearable item comprising such a size-adjustable fabric, as well as methods of expanding and reducing size of such a size-adjustable fabric. There is further disclosed footwear and protective wear comprising such size-adjustable fabric.

Claims (35)

1 . A wearable item comprising:

a first flexible fixed-size fabric portion,

a second flexible fixed-size fabric portion, and

a patch, formed of a size-adjustable fabric comprising:

a first set of threads, each formed of a heat-shrink polymer material, at least one conducting thread, formed of an electrically conducting material, wherein the first set of threads ( 10 a - 10 i ) runs substantially parallel with each other, and wherein the conducting thread ( 20 ) runs substantially across the first set of threads

wherein the patch is arranged between and connecting said first and second fixed-size fabric portions, wherein the first set of threads extend at a greater angle to at least one of the first and second fixed-size fabric portions than the conducting thread.

2 . The wearable item as claimed in claim 1 , wherein the first set of threads forms a set of warp threads, and wherein the conducting thread forms a weft thread.

3 . The wearable item as claimed in claim 1 , wherein the conducting thread extends at an angle of 80-100 degs to the first set of threads.

4 . The wearable item fabric as claimed in claim 1 , wherein the heat-shrink polymer material comprises as least one material selected from a group consisting of a polyolefin, a polyester, a polyvinyl chloride (PVC), a fluorocarbon-based synthetic rubber, a polychloroprene rubber, a polytetrafluoroethylene (PTFE), an elastomer, a fluorinated ethylene propylene (FEP) and a polyvinylidene fluoride (PVDF).

5 . The wearable item fabric as claimed in claim 1 , wherein the heat-shrink polymer material is a crosslinked and subsequently expanded polymer material.

6 . The wearable item fabric as claimed in claim 1 , further comprising at least one non-conducting thread, which extends mainly parallel with the conducting thread.

7 . The wearable item as claimed in claim 1 , wherein the conducting thread runs across the entire first set of threads ( 10 a - 10 i ).

8 . The wearable item as claimed in claim 1 , wherein the conducting thread, at least at some section along a length direction of the first set of threads, runs across less than all threads of the first set of threads.

9 . The wearable item as claimed in claim 1 , wherein the threads of the first set of threads present at least two different lengths.

10 . The wearable item as claimed in claim 1 , further comprising at least one expansion limiting thread, which extends parallel with the first set of threads, wherein the expansion limiting thread, when the first set of threads are in a contracted state, present curved portions between crossing portions of the conducting thread.

11 . A footwear, comprising:

a first flexible fixed-size material portion,

a second flexible fixed-size material portion, and

a patch, formed of a size-adjustable fabric, comprising: a first set of threads, each formed of a heat-shrink polymer material, at least one conducting thread, formed of an electrically conducting material, wherein the first set of threads runs substantially parallel with each other, and wherein the conducting thread runs substantially across the first set of threads,

wherein the patch is arranged between and connecting said first and second fixed-size material portions,

wherein the patch is positioned at a shaft portion of the footwear, and

wherein the first set of threads extend substantially along a circumference direction of a shaft of the footwear, such that a shaft width is adjustable.

12 . The footwear as claimed in claim 11 , wherein the conducting thread, at least at some section along a length direction of the first set of threads, runs across less than all threads of the first set of threads.

13 . The footwear as claimed in claim 11 , further comprising at least one non-conducting thread, which extends mainly parallel with the conducting thread.

14 . The footwear as claimed in claim 11 , further comprising at least one expansion limiting thread, which extends parallel with the first set of threads, wherein the expansion limiting thread, when the first set of threads are in a contracted state, present curved portions between crossing portions of the conducting thread.

15 . A protective wear, comprising:

a first protecting body,

a second protecting body, and

a patch ( 113 ), formed of a size-adjustable fabric, comprising: a first set of threads, each formed of a heat-shrink polymer material, at least one conducting thread, formed of an electrically conducting material, wherein the first set of threads runs substantially parallel with each other, and wherein the conducting thread runs substantially across the first set of threads,

wherein the patch is arranged between and connecting said first and second protecting bodies, and

wherein the first set of threads extend substantially between the first and second protecting bodies, such that a distance between the protecting bodies is adjustable.

16 . The protective wear as claimed in claim 15 , wherein the conducting thread, at least at some section along a length direction of the first set of threads, runs across less than all threads of the first set of threads.

17 . The protective wear as claimed in claim 15 , wherein at least one of the protective first and second bodies includes ballistic protection material.

18 . The footwear as claimed in claim 15 , further comprising at least one non-conducting thread, which extends mainly parallel with the conducting thread.

19 . The footwear as claimed in claim 15 , further comprising at least one expansion limiting thread, which extends parallel with the first set of threads, wherein the expansion limiting thread, when the first set of threads are in a contracted state, present curved portions between crossing portions of the conducting thread.
