Abstract

Abstract A synthetic fur product and method of making such product which comprises coating synthetic hair fibers with a heat-settable composition containing a hardening and adhesive agent in aqueous media, either with or without the addition of separate waterproofing agents, flame-retardant agents, softening agents, and the like, and then applying heat to the coated hair to set the coated hair in the selected condition. Then the treated hair fibers are formed into long and short hair wefts, the two lengths and ''''belly'''' hair. The wefts are then stitched or otherwise adhered to a backer. In another form, only one length of hair fiber is used to form the wefts and these are stitched to a woven mat which has been treated similarly to the wefts.
