Woven fabric of noble metal filament, and an apparatus and method of manufacturing the same

Abstract

The present invention can provide thin elastic woven fabric of noble metal monofilament, which is impossible to fabricate in the prior art and which is suitable in use for apparel and garniture designs. In the woven fabric produced according to the present invention, at least either of weft and warp is 0.12 to 6.5 N in tensile strength. Preferably, the noble metal monofilament of 1.5% or above in elongation percentage is used. Additionally, it is preferable that 14-carat gold, 18-carat gold, 24-carat gold, or gold alloy is used for the noble metal monofilament. In another aspect of the present invention, a method of manufacturing woven fabric from noble metal filament includes the steps of setting up warp through two preparation stages of warping and adjusting loom mechanism, setting up weft of noble metal monofilament by using a filling winder to wind the weft on a bobbin, and weaving the warp and weft into fabric at a shuttle loom, and in the step of using a filling winder to wind the weft on a bobbin, a rotation velocity at which the weft is wound on the bobbin is continuously altered.

What is claimed is:  
     
         1 . Fabric woven from noble metal filament in which at least one of warp and weft is of noble metal monofilament that is 0.12 to 6.5 N in tensile strength.  
     
     
         2 . Woven fabric according to  claim 1 , wherein the noble metal monofilament is 1.5% or above in elongation percentage.  
     
     
         3 . Woven fabric according to  claim 1  or  claim 2 , wherein the noble metal monofilament is of 14-carat gold, 18-carat gold, 24-carat gold, or gold alloy.  
     
     
         4 . A method of manufacturing woven fabric from noble metal filament, comprising the steps of setting up warp through preparation stages of 
 warping and adjusting loom mechanism,    setting up weft of noble metal monofilament by using a filling winder to wind the weft on a bobbin, and    weaving the warp and weft into fabric at a shuttle loom,    in the step of using a filling winder to wind the weft on a bobbin, a rotation velocity at which the weft is wound on the bobbin being continuously altered.    
     
     
         5 . An apparatus of manufacturing fabric from noble metal filament, comprising 
 a warper for setting up warp,    a filling winder for winding weft of noble metal monofilament on a bobbin to set up the weft, and    a shuttle loom at which the weft and warp set up in the previous steps are woven,    the filling winder having a speed-varying means to continuously alter a rotation velocity at which the weft is wound on the bobbin.    
     
     
         6 . An apparatus according to  claim 5 , wherein the speed-varying means is an inverter.
