Method of making simulated denim garments

Abstract

A method of making a simulated denim garment which comprises constructing a woven garment using dyeable warp yarns and non-dyeable weft yarns and dying the thus-constructed garment using a reduced liquid indigo dye or cotton dye. Cotton is a preferred warp yarn. Dyeable and non-dyeable materials may also be spun together to form a yarn, which can be dyed either in a yarn form or as constructed into a knitted garment.

1 . The process of making a simulated denim fabric, which comprises
 providing a first set of yarns formed of cotton or other dyeable fiber,   providing a second set of yarns formed of polyester, polypropylene or other non-dyeable fiber, and   constructing a fabric comprised of 35% to 65% of one of said yarns and 65% to 35% of the other of said yarns.   
     
     
         2 . The process of  claim 1 , in which
 the thus-constructed fabric is thereafter dyed with a reduced liquid blue indigo dye.   
     
     
         3 . The process of  claim 1 , in which
 said first set of yarns comprises warp yarns and said second set of yarns comprises weft yarns, and   said yarns are woven to form said fabric.   
     
     
         4 . The process of  claim 3 , in which
 the thus woven fabric is thereafter dyed using a reduced liquid blue indigo dye or a cotton dye.   
     
     
         5 . The process of  claim 1 , in which
 said first and second sets of yarns are knitted to form a fabric.   
     
     
         6 . The process of  claim 5 , in which
 the thus knitted fabric is thereafter dyed using a reduced liquid blue indigo dye or cotton dye.   
     
     
         7 . The process of making indigo-dyed yarns which comprises,
 combining 65% to 35% by weight of cotton fiber with 35% to 65% by weight of non-dyeable fiber, and   dyeing the combined yarns with a reduced liquid blue indigo dye.   
     
     
         8 . The process of  claim 7 , in which
 said combined yarns, before dyeing are constructed into a garment, and   thereafter the garment is dyed with said reduced liquid blue indigo dye.   
     
     
         9 . The process of  claim 7 , in which
 said non-dyeable fiber is polypropylene,   said cotton fiber and said polypropylene fiber are carded separately to form separate slivers if cotton and polypropylene,   the separate slivers are combined at a draw frame and thereafter spun into a yarn.
