Textile sheet product

Abstract

A textile sheet product ( 1 ) including a thermoplastic filament ( 2 ) extending along a filament path ( 3 ), wherein the thermoplastic filament ( 2 ) forms a plurality of partially superimposed loops (L 1 , L 2 ) along the filament path ( 3 ) and a plurality of crossings (c 1 , c 2 , c 3 , c 4 ) at which the thermoplastic filament ( 2 ) crosses itself and forms a material-bonded, in particular fused connection with itself. Furthermore, an upper with such a sheet product and a shoe with such an upper is disclosed.

         6 . The textile sheet product according to  claim 1 , wherein the textile sheet product comprises a filament crossing density of at least 200 crossings per cm2. 
     
     
         7 . The textile sheet product according to  claim 1 , wherein the textile sheet product comprises a loop density of 0.5 to 15 loops per cm 2 . 
     
     
         8 . The textile sheet product according to  claim 1 , wherein the thermoplastic filament forms a plurality of fused bulge portions, formed from multiple fused together filament sections of the thermoplastic filament. 
     
     
         9 . The textile sheet product according to  claim 1 , wherein the polygonal loops are arranged along the filament path one after another and wherein the crossings are arranged along the filament path underneath a perpendicular filament path. 
     
     
         10 . The textile sheet product according to  claim 1 , wherein each polygonal loop defines a maximum clear distance of 5 mm to 30 mm. 
     
     
         11 . The textile sheet product according to  claim 1 , wherein the thermoplastic filament comprises a maximum filament thickness (t) of 50 μm to 300 μm. 
     
     
         12 . The textile sheet product according to  claim 1 , wherein the plurality of polygonal loops form a regular laying pattern. 
     
     
         13 . The textile sheet product according to  claim 1 , wherein each crossing comprises a protuberance with a height being larger than a maximum filament thickness of the thermoplastic filament. 
     
     
         14 . The textile sheet product according to  claim 1  comprising a longitudinal elongation along a direction of the filament path at break of 15 to 100 N. 
     
     
         15 . The textile sheet product according to  claim 1  comprising a transversal elongation along a direction perpendicular to a direction of the filament path at break of 10 to 70 N. 
     
     
         16 . The textile sheet product according to  claim 1  wherein a longitudinal elongation along a direction of the filament path is higher than a transversal elongation along a direction perpendicular to the direction of the filament path. 
     
     
         17 . The textile sheet product according to  claim 1 , wherein the thermoplastic filament comprises, along the polygonal loops, a crossing number of at least 100.
