Abstract
A formaldehyde-free composition for finishing fabrics, the use thereof, and the fabrics obtained thereby are disclosed, the finishing composition being an aqueous dispersion containing from 10-50% by weight of a polymeric resin binder such as a carboxy-modified polymer, 1-10% by weight of an aqueous-dispersible epoxy resin or blend of said resin with another thermosetting resin and one or more additives such as surfactants, delustrants, antistatic agents, flame retardants, fillers, thickeners, catalysts, as needed.
Claims12
A method of finishing a polyester yarn or fabric which comprises the steps of (a) treating the yarn or fabric by applying thereto a formaldehyde-free aqueous composition and (b) drying the treated yarn or fabric at a temperature of about 350.degree.-450.degree. F. for 20 to 60 seconds;
- wherein the formaldehyde-free aqueous composition comprises an aqueous dispersion containing:
- from 10-50% by weight of a polymeric resin binder selected from the group consisting of an acrylic resin, a polyvinyl chloride, a polyvinyl alcohol, a polyvinyl acetate, a polystyrene, and a mixture thereof;
- and
- 1-10% by weight of a water dispersible thermosetting resin comprising an epoxy resin containing bisphenol-A or a blend of said epoxy resin containing bisphenol-A with another thermosetting resin which is not the same as said epoxy resin containing bisphenol-A.
Polyester fabric finished with a formaldehyde-free aqueous composition comprising an aqueous dispersion containing:
- from 10-50% by weight of a polymeric resin binder selected from the group consisting of an acrylic resin, a polyvinyl chloride, a polyvinyl alcohol, a polyvinyl acetate, a polystyrene, and a mixture thereof;
- and
- 1-10% by weight of a water dispersible thermosetting resin comprising an epoxy resin containing bisphenol-A or a blend of said epoxy resin containing bisphenol-A with another thermosetting resin which is not the same as said epoxy resin containing bisphenol-A.
A formaldehyde-free aqueous composition for finishing a polyester fabric comprising an aqueous dispersion containing:
- 10% by weight of a polymeric resin binder selected from the group consisting of an acrylic resin, a polyvinyl chloride, a polyvinyl alcohol, a polyvinyl acetate, a polystyrene, and a mixture thereof;
- 10% by weight of a water dispersible thermosetting resin comprising an epoxy resin containing bisphenol-A or a blend of said epoxy resin containing bisphenol-A with another thermosetting resin which is not the same as said epoxy resin containing bisphenol-A;
- and
- 2% by weight of a delustrant, 2% by weight of an antistatic agent and 2% by weight of a surfactant.
A formaldehyde-free aqueous composition for finishing a polyester fabric comprising an aqueous dispersion containing:
- 20% by weight of a polymeric resin binder selected from the group consisting of an acrylic resin, a polyvinyl chloride, a polyvinyl alcohol, a polyvinyl acetate, a polystyrene, and a mixture thereof;
- 5% by weight of a water dispersible thermosetting resin comprising an epoxy resin containing bisphenol-A or a blend of said epoxy resin containing bisphenol-A with another thermosetting resin which is not the same as said epoxy resin containing bisphenol-A;
- and
- 2% by weight of a delustrant, 2% by weight of an antistatic agent and 2% by weight of a surfactant.
