Anti-slip leakproof roofing sailcloth for building

Abstract

A roofing sailcloth for a building includes a substrate of woven cloth, anti-slipping material woven to the substrate to increase surface roughness of a face of the substrate, and a leakproof layer bonded to the other face of the substrate. The roofing sailcloth is waterproof and leakproof and has high tensile strength and high tearing strength. Furthermore, the roofing sailcloth has improved anti-slipping effect to allow a worker to walk on the sailcloth safely and easily. Furthermore, the roofing sailcloth is light and allows easy transport to improve constructing efficiency. Furthermore, the roofing sailcloth possesses excellent anti-aging properties.

1 . A roofing sailcloth for a building, comprising:
 a substrate of woven cloth, with the substrate including a first face and a second face opposite to the first face;   anti-slipping material woven to the substrate to increase surface roughness of the first face of the substrate; and   a leakproof layer bonded to the second face of the substrate.

       3 . The roofing sailcloth as claimed in  claim 1 , with the anti-slipping material including fibers, yarns, or flat yarns having a napped surface. 
   
   
       4 . The roofing sailcloth as claimed in  claim 2 , with the anti-slipping material including fibers, yarns, or flat yarns having a napped surface. 
   
   
       5 . The roofing sailcloth as claimed in  claim 1 , with the leakproof layer being made of thermoplastic elastomer or plastic material. 
   
   
       6 . The roofing sailcloth as claimed in  claim 2 , with the leakproof layer being made of thermoplastic elastomer or plastic material. 
   
   
       7 . The roofing sailcloth as claimed in  claim 3 , with the leakproof layer being made of thermoplastic elastomer or plastic material. 
   
   
       8 . The roofing sailcloth as claimed in  claim 4 , with the anti-slipping material including fibers, yarns, or flat yarns having a napped surface. 
   
   
       9 . The roofing sailcloth as claimed in  claim 1 , further comprising a plurality of protrusions bonded to or printed on an outer face of the leakproof layer, with the protrusions being made of thermoplastic elastomers and forming an anti-slipping layer. 
   
   
       10 . The roofing sailcloth as claimed in  claim 2 , further comprising a plurality of protrusions bonded to or printed on an outer face of the leakproof layer, with the protrusions being made of thermoplastic elastomers and forming an anti-slipping layer. 
   
   
       11 . The roofing sailcloth as claimed in  claim 3 , further comprising a plurality of protrusions bonded to or printed on an outer face of the leakproof layer, with the protrusions being made of thermoplastic elastomers and forming an anti-slipping layer. 
   
   
       12 . The roofing sailcloth as claimed in  claim 5 , further comprising a plurality of protrusions bonded to or printed on an outer face of the leakproof layer, with the protrusions being made of thermoplastic elastomers and forming an anti-slipping layer. 
   
   
       13 . The roofing sailcloth as claimed in  claim 1 , with a plurality of spaced rows of anti-slipping material being formed on the first face of the substrate and spaced from each other in a weft direction. 
   
   
       14 . The roofing sailcloth as claimed in  claim 2 , with a plurality of spaced rows of anti-slipping material being formed on the first face of the substrate and spaced from each other in a weft direction. 
   
   
       15 . The roofing sailcloth as claimed in  claim 1 , with a plurality of spaced rows of anti-slipping material being formed on the first face of the substrate and spaced from each other in a warp direction. 
   
   
       16 . The roofing sailcloth as claimed in  claim 13 , with a plurality of spaced second rows of anti-slipping material being formed on the first face of the substrate and spaced from each other in a warp direction. 
   
   
       17 . The roofing sailcloth as claimed in  claim 1 , with the woven cloth being woven from polymer strips stretched in a single direction by plainweave or twill weave. 
   
   
       18 . The roofing sailcloth as claimed in  claim 2 , with the woven cloth being woven from polymer strips stretched in a single direction by plainweave or twill weave. 
   
   
       19 . The roofing sailcloth as claimed in  claim 4 , with the woven cloth being woven from polymer strips stretched in a single direction by plainweave or twill weave. 
   
   
       20 . The roofing sailcloth as claimed in  claim 9 , with the woven cloth being woven from polymer strips stretched in a single direction by plainweave or twill weave.
