Method of coating nylon and polyester fibers with water dispersible polyvinyl acetate and coating achieved therefrom

Abstract

An aqueous, coatable, thermally condensable composition is disclosed. The coating is based on dispersions of vinyl acetate polymers in water. Uniquely, the coating can be advantageously used for both nylon and polyester yarns. The coated yarns exhibit performance equivalent to or better than coated yarns based on traditional compositions.

What is claimed is:  
     
       1. A coatable, thermally condensable composition comprising an aqueous dispersion of a vinyl acetate polymer. 
     
     
       2. The composition of claim  1  additionally comprising at least one additive selected from the group consisting of a polymer binder, an adhesion promoter, coupling agents, and UV stabilizers. 
     
     
       3. A process for producing a break resistant, coated solution dyed nylon, non-solution dyed nylon, or polyester yarn comprising passing a previously dyed solution dyed nylon, non-solution dyed nylon, or polyester yarn through a bath containing a water and polyvinyl acetate dispersion; passing the yarn now coated with a layer of the water and polyvinyl acetate dispersion through a drying stage; and recovering a bonded yarn possessing a solid coating of polyvinyl acetate. 
     
     
       4. The process of claim  3 , wherein the bath additionally contains at least one additive selected from the group consisting of coupling agents, UV stabilizers, polymer binders, adhesion promoters, plasticizers, wetting agents, and antifoaming agents.
