Abstract
A fabric comprising elongated steel elements is provided. This fabric is to be used to provide cut-resistance or reinforcement for protective textiles. Elongated steel elements are in contact relationship, so improving the resistance to knife cutting actions.
Claims24
A fabric comprising a warp and a weft, said warp comprising warp elements, said weft comprising weft elements, wherein said fabric has a steel covering ratio of less than 60%, wherein at least one of said warp elements or at least one of said weft elements or both comprise two or more elongated steel elements being in contact relationship with each other.
A fabric comprising a warp and a weft, said warp comprising warp elements, said weft comprising weft elements, wherein at least one of said warp elements or at least one of said weft elements or both comprise two or more elongated steel elements being in contact relationship with each other, and wherein said fabric has a steel covering ratio is less than 40%.
A fabric comprising a warp and a weft, said warp comprising warp elements, said weft comprising weft elements;
- wherein at least one of
- i) said warp elements comprises a plurality of warps in substantial contact relationship with each other or
- ii) said weft elements comprise a plurality wefts in substantial contact relationship with each other or
- iii) said warp elements and at least one of said weft elements comprise a plurality of warps and wefts, respectively, in substantial contact relationship with each other, respectively;
- wherein (n) type(s) of elongated steel elements are present in a warp direction and (m) type(s) of elongated steel elements are present in a weft direction;
- and wherein said fabric has a steel covering ratio (Cs) of less than 60% as determined by the following equation:
- Cs=[B*(Σnαn*Dan)+A*(Σmβm*Dbm)−(Σnαn*Dan)*(Σmβm*Dbm)]*100/A*B,
- where:
- A =length of the fabric in warp direction,
- B =length of the fabric in welt direction,
- α=Number of elongated steel elements present in the warp direction,
- β=Number of elongated steel elements present in the weft direct,
- Da=diameter of the elongated steel element in warp direction A,
- Db =diameter of the elongated steel element in welt direction B,
- Σnαn*Dan=α1*Da1+α2*Da2+ . . . +αn*Dan, and
- ΣmβmDbm=β1*Db1+β2*Db2+ . . . +βmDbm.
