Abstract
Running and tearing of nylon hosiery and other hydrophobic fabrics are prevented by immersing the hosiery and fabrics in a special aqueous treatment comprising a film-forming polymeric solution, a wetting agent, a substantive quaternary compound and fabric softener to encourage attachment to the substrate, and an elasticity enhancing plasticizer.
Claims14
A process for enhancing the performance and wearing qualities of textile fibers by treating the textile fibers with a composition produced by the steps, comprising:
- aquatically mixing a quaternary compound having an affinity to enhance the softness and abrasion resistance of textile fibers selected from the group consisting of nylon, rayon, dacron, cotton, linen, hemp, polyester, polyethylene, polypropylene, polyamides, wool, and silk, with
- a partially hydrolyzed film-forming polymer having an affinity to attach to said textile fibers, said polymer being selected from the group consisting of polyvinyl alcohol and polyvinyl acetate, after
- mixing a plasticizer with said polymer to increase the strength of the textile fibers, said plasticizer being selected from the group consisting of propylene glycol, ethylene glycol, diethylene glycol, dipropylene glycol, hexylene glycol, tetraethylene glycol, 2 pyrolodone, tributoxylethyl phosphate, dibutyl phthalate, and diethyl phthalate.
A process for enhancing the performance of clothing selected from the group consisting of nylon stockings, pantyhose, fabrics, synthetic fibers, and hydrophobic textiles, by treating said clothing with an effective film forming amount of a composition comprising by weight:
- from about 60% to about 90% water;
- from about 0.01 to about 2% surface tension decreasing additives comprising a member selected from the group consisting of ammonium perfluoroalkyl sulfonates, fluorinated alkyl alkoxylates, ammonium perfluoroalkyl sulfonates, potassium fluoroalkyl carboxylates, and fluoroaliphatic oxyethylene adducts, telomer B, and polytetraethylene;
- from about 0.1% to about 1% silicon-containing defoamer;
- from about 0.5% to about 10% partially hydrolyzed film-forming polymer selected from the group consisting of polyvinyl alcohol and polyvinyl acetate;
- from about 0.5% to about 15% plasticizer selected from the group consisting of propylene glycol, ethylene glycol, diethylene glycol, dipropylene glycol, hexylene glycol, tetraethylene glycol, 2 pyrolodone, tributoxylethyl phosphate, dibutyl phthalate, and diethyl phthalate;
- and
- from about 0.2% to about 25% quaternary compound having an affinity to adhere to the clothing.
A process for producing a composition for treating and enhancing the performance of clothing, comprising the steps of:
- dispensing a liquid comprising water into a vessel selected from the group consisting of a tank, tub trough, bowl, and container;
- regulating the temperature of the liquid in the vessel in the range from about 35 degrees F. (2 degrees C.) to about 150 degrees F. (66 degrees C.);
- lowering the surface tension of the liquid with at least one member selected from the group consisting of a wetting agent, emulsifier and surfactant, to enhance the adhesion of the composition on clothing;
- defoaming the liquid;
- mixing a partially hydrolyzed polymer having an affinity to form a film and attach to said clothing with said defoamed liquid;
- enhancing the strength, elasticity and film forming qualities of said polymer with a plasticizer;
- forming a colloidal polymeric suspension of said polymer and said plasticizer;
- increasing the abrasion resistance, bursting strength and softness of the clothing by mixing and attaching a quaternary ammonium compound to the clothing with the colloidal polymeric suspension of said polymer and plasticizer;
- coloring said polymeric colloidal suspension with at least one biodegradable colorants;
- preventing biodegrading, smelling and streaking of said polymeric colloidal suspension;
- and
- separating said polymeric colloidal suspension with said quaternary compound from a substantial portion of said liquid to form a composition useful to resist tearing of clothing.
