Impregnated-yarn cloth and process for producing impregnated-yarn cloth

Abstract

A process for producing an impregnated-yarn cloth which is woven fabric configured of impregnated yarns, which has satisfactory shaping properties and, despite this, has a fine texture of the reinforced fiber bundles, and which gives a molded object having excellent strength. The process for producing an impregnated-yarn cloth ( 1 ) is characterized by impregnating fiber bundles ( 2 ) with a thermoplastic resin ( 5 ) held in a molten state in a resin tank, while or after twisting the fiber bundles ( 2 ) at a rate of 20 twists/m or more and 700 twists/m or less, to form an impregnated yarn ( 3 ); and knitting or weaving the thus-formed impregnated yarns ( 3 ) to obtain the impregnated-yarn cloth ( 1 ).

1 . A process for producing an impregnated-yarn cloth, comprising:
 immersing fiber bundles with a thermoplastic resin stored in a molten state in a resin tank, while or after twisting the fiber bundles at a rate of 20 twists/m or more and 700 twists/m or less, to form an impregnated yarn; and   knitting or weaving the thus-formed impregnated yarns to obtain the impregnated-yarn cloth.   
     
     
         2 . The process for producing an impregnated-yarn cloth according to  claim 1 ,
 wherein the impregnated yarns are knitted or woven so that the aperture is 0 mm or more and 10 mm or less.   
     
     
         3 . An impregnated-yarn cloth in which fiber bundles coated with a thermoplastic resin are mutually knitted or woven, and the fiber bundles are twisted at a rate of 20 twists/m or more and 700 twists/m or less. 
     
     
         4 . The impregnated-yarn cloth according to  claim 3 , wherein the fiber bundles are knitted or woven so that the aperture is 0 mm or more and 10 mm or less.
