Length-ways stretchable elastic band

Abstract

A length-ways stretchable elastic band is provided with plural areas of stretchable elastic yarns and elastic silk areas. The elastic yam areas are connected to one another by an elastic silk area formed via length-ways knitting and sewing, such that in said areas, the direction that the elastic silk is knitted vertically intersects or obliquely connects with the direction that the elastic band is to be extended. As such, when the elastic band is under force, it can be expanded both length-ways and width-ways, thereby obtaining a multi-directional extensibility. Meanwhile, the elastic band would have an outer appearance full of unique visual effect like a silk ribbon that makes the elastic band productions more fine and delicate.

1 . A lengthways stretchable elastic band, composed of plural areas of stretchable elastic yams and elastic silk areas which are formed via knitting and sewing, characterized in that: 
 the elastic yarn areas are connected to one another by an elastic silk area formed via lengthways knitting and sewing; in said areas, the direction that the elastic silk is knitted interests the direction that the elastic band is to be extended.    
   
   
       2 . The lengthways stretchable elastic band according to  claim 1 , wherein the elastic yarns may have an identical width.  
   
   
       3 . The lengthways stretchable elastic band according to  claim 1 , wherein the elastic yarns may have various widths.  
   
   
       4 . A lengthways stretchable elastic band, composed of plural areas of stretchable elastic yams and elastic silk areas formed via knitting and sewing, characterized in that: 
 the elastic yarn areas are connected to one another by an elastic silk area formed via oblique knitting and sewing.
