Voluminous non-woven fabric

Abstract

A voluminous non-woven fabric that has a textured yarn shot through it, at least in one preferential direction, where an endless filament and/or staple fiber non-woven fabric with a mass per unit area of 5 to 100 g/m 2 has a textured multifilament yarn with a titer in the range of 10 to 400 dtex shot through it, and where the distance of the multifilament yarns from one another is 1 to 10/cm, and the mesh number is 0.5 to 8/cm, and the multifilament yarn threads are shrunk by 3 to 80%, using moist-thermal or wet-thermal treatment.

What is claimed is:  
     
         1 . A voluminous non-woven fabric having a textured yarn shot through it, at least in one preferential direction, comprising: an endless filament or staple fiber non-woven fabric having a density of 5 to 100 g/m 2  and a textured multifilament yarn having a titer in the range of 10 to 400 dtex shot through the fabric, wherein the multifilament yarns are separated from one another by a distance of 1/cm to 10/cm and the mesh number is 0.5/cm to 8/cm, and the multifilament yarn threads are shrunk by 3 to 80%, using moist-thermal or wet-thermal treatment.  
     
     
         2 . The voluminous non-woven fabric according to  claim 1 , wherein: the endless filament or staple fiber non-woven fabric has a density of 7 to 60 g/m 2 ; the textured multifilament yarn has a titer in the range of 30 to 300 dtex; the distance of the multifilament fibers from one another is 3/cm to 7/cm; the mesh number is 0.5/cm to 4/cm; and the multifilament yarn threads have been shrunk by 5 to 60%.  
     
     
         3 . The voluminous non-woven fabric according to  claim 1 , wherein the endless filament or staple fiber non-woven fabric has a density of 10 to 40 g/m 2  and is provided with a bonding pattern that covers part of the surface, covering 2 to 35% of the surface, and wherein the multifilament yarn threads are shrunk by 8 to 35%.  
     
     
         4 . The voluminous non-woven fabric according to  claim 2 , wherein the endless filament or staple fiber non-woven fabric has a density of 10 to 40 g/m 2  and is provided with a bonding pattern that covers part of the surface, covering 2 to 35% of the surface, and wherein the multifilament yarn threads are shrunk by 8 to 35%.  
     
     
         5 . The voluminous non-woven fabric according to  claim 3 , wherein the bonding pattern that covers part of the surface covers 4 to 25% of the surface.  
     
     
         6 . The voluminous non-woven fabric according to  claim 1 , wherein the titer of the fibers or filaments of the non-woven fabric is from 0.05 to 4.4 dtex, and where up to 20% by weight of the total fibers and/or filaments can have a coarser titer than 4.4 dtex, provided that the arithmetically determined average of the fiber and/or filament titer of all the fibers and/or filaments in the non-woven fabric does not exceed 4.4 dtex.  
     
     
         7 . The voluminous non-woven fabric according to  claim 1 , wherein shrinkage of the multifilament yarn is triggered at a temperature at least 25° C. below the plastification temperature of those fibers or filaments in the non-woven fabric haaving the lowest plastification range.  
     
     
         8 . The voluminous non-woven fabric according to  claim 1 , wherein the non-woven fabric is stretched crosswise to the machine running direction.  
     
     
         9 . The voluminous non-woven fabric according to  claim 1 , wherein at least 20% by weight of the total fibers and/or filaments are inherently hydrophilic, and the remaining portion of the total fibers and/or filaments are synthetic.  
     
     
         10 . The voluminous non-woven fabric according to  claim 8 , wherein at least a part of the synthetic fibers and/or filaments are made to be hydrophilic.  
     
     
         11 . The voluminous non-woven fabric according to  claim 1 , wherein at least some of the fibers or filaments are superabsorbent or have a core which is coated with a superabsorbent polymer.  
     
     
         12 . The voluminous non-woven fabric according to  claim 1 , wherein it contains crimped and dyed fibers or filaments.  
     
     
         13 . The voluminous non-woven fabric according to  claim 1 , wherein it is impregnated with a silicone oil lubricant.  
     
     
         14 . The voluminous non-woven fabric according to  claim 1 , wherein it has two sides that are different in their composition or their structure.  
     
     
         15 . The voluminous non-woven fabric according to  claim 1 , wherein it is folded at least once.  
     
     
         16 . The voluminous non-woven fabric according to  claim 1 , wherein it is impregnated with a cleaning or care emulsion.  
     
     
         17 . A wiping, cleaning, or body care cloth comprising the voluminous non-woven fabric according to  claim 1.
