Abstract

A pressurized pretreatment process for removal of stains on fabrics prior to washing employing means for delivering a stain pretreating solution under the pressure of water or air or a combination of water and air. Stains are effectively removed on such fabrics as polyester/cotton blends and cotton, and a washing machine having delivery means for delivering a stain pretreating solution under pressure.

Claims

1. A pressure stain treating process for pretreating a stain on a fabric which process comprises the steps of (1) selecting a stain treating solution for user selective formulation using a control means and applying said user selected stain treating solution to the fabric via a single delivery means regardless of the stain treating solution selected, (2) subjecting the stain treating solution to sufficient pressure to cause the stain treating solution to penetrate the stain and then (3) washing the treated stained fabric;

and wherein said stain treating solution and pressure is applied external to a clothes washing container.

2. The process of claim 1 wherein said pressure is from water at a pressure of about 45 to about 65 psig.

3. The process of claim 1 wherein said pressure is from air at a pressure of about 10 to about 100 psig.

4. The process of claim 1 wherein said pressure is from a combination of water and air pressure.

5. The process of claim 1 wherein the stain treating solution is a liquid stain remover.

6. The process of claim 1 wherein the stain treating solution is a liquid detergent.

7. The process of claim 1 wherein an air compressor is employed to provide air pressure.

8. The process of claim 7 wherein an air surge tank is employed to provide air at a constant controlled pressure.

9. The process of claim 1 wherein said stain treating solution is applied to said stained fabric in combination with the pressure of water, air, or a combination of water and air.

10. The process of claim 1 further comprising selecting the pressure of air and/or water, or combination thereof, by way of a selector control valve, used to deliver a stain treating solution of user selective formulation.

11. The process of claim 1 further comprising selecting the dilution of a stain treating solution of user selective formulation with water and/or air under pressure.

12. The process of claim 1 further comprising selecting different stain treating solutions or a combination of stain treating solutions of user selective formulation with water and/or air under pressure.
