Claims
- 1. An article of manufacture comprising (i) a fabric substrate and (ii) an insect-repellant composition, wherein said insect-repellant composition is prepared as an aqueous consisting essentially of an amine insect-repellant, at least two reactive silicones soluble with said amine insect-repellant, and starch; said insect-repellant composition being dried into a powder and applied to said fabric at from about 2% to about 30% on weight of fabric (owf), to form said article of manufacture having insect repellancy.
- 2. The article of manufacture of claim 1 wherein at least one finishing agent is added to said powder before application onto said fabric substrate.
- 3. The article of manufacture of claim 1 wherein said application of said insect-repellant composition comprises the step of adding an effective amount of said powder to a dye bath and dyeing said fabric substrate.
- 4. The article of manufacture of claim 3 wherein said application of said insect-repellant composition further comprises the step of adding an effective amount of said powder to a print paste and printing on said fabric substrate.
- 5. The article of manufacture of claim 4 wherein said application further comprises the step of adding an effective amount of said powder to a finishing solution, said finishing solution comprising at least one reactive silicone and applying said finishing solution to said fabric substrate to form said fabric composition.
- 6. The article of manufacture of claim 1 wherein said starch of said insect-repellant composition is a modified starch.
- 7. The article of manufacture of claim 1 wherein said amine insect-repellant of said insect-repellant composition is N,N'-diethyl-m-toluamide.
- 8. The article of manufacture of claim 7 wherein N,N'-diethyl-m-toluamide consists from about 1% to about 15% (owf).
- 9. The article of manufacture of claim 1 wherein said fabric substrate is selected from the group consisting of woven, non-woven and knit substrates.
- 10. The article of manufacture of claim 2 wherein said finishing agent comprises at least a finishing agent, a softener and a wax emulsion.
- 11. The article of manufacture of claim 1 wherein said finishing agent is selected from the group consisting of glyoxal resins, urea-formaldehyde resins, acrylic resins, polyvinyl acetates, polyvinyl alcohols, melamine, and fluorocarbon resins.
- 12. The article of manufacture of claim 1 wherein said fabric composition has insect-repellant efficacy for at least one week.
- 13. An article of manufacture comprising (i) a fabric substrate and (ii) an insect-repellant composition applied to said substrate, wherein said article of manufacture is prepared by the steps of:
- (a) mixing an aqueous dispersion consisting essentially of N,N'-diethyl-m-tolumide, a reactive silane, and starch; and
- (b) spray drying said aqueous dispersion of step (a) to form a powder;
- wherein said article of manufacture has insect-repellancy, and said insect-repellent composition being present on said substrate from about 2% to about 30% (owf).
- 14. The fabric composition of claim 13 wherein said fabric composition has insect-repellant efficacy for at least one week.
- 15. An article of manufacture as in claim 13 further comprising the steps of adding an effective amount of said powder formed in step (b) to a dye bath and dyeing said fabric substrate.
- 16. An article of manufacture as in claim 13 further comprising the steps of adding an effective amount of said powder formed in step (b) to a print paste and printing with said print paste on said fabric substrate.
- 17. An article of manufacture as in claim 13 further comprising the steps of adding an effective amount of said powder formed in step (b) to a finishing solution comprising a finishing agent and applying the finishing solution to said fabric substrate.
