Abstract
A method of washing fabric articles provides a washer extractor having a reservoir for holding fabric articles and a washing liquid. A washing liquid is pumped from the reservoir to the washer extractor interior. The ratio of pounds of washing liquid to pounds of fabric articles is about 4 to 1, plus absorbed water. Fluid is pulse flowed to the textile articles at a volume of between about 0.5 to 2 gallons (2 to 8 liters) per pound (0.45 kg) of fabric articles for a selected time interval. Washing chemicals are added to the washer extractor. Water is transmitted to the washer extractor at the rate of 0.35 to 0.6 gallons (1.33 to 2.3 liters) of water per pound (0.45 kg) of fabric articles within a selected time interval.

- a) providing a reservoir of washing liquid;
- b) providing a washer extractor having an interior for holding fabric articles;
- c) placing fabric articles to be washed in the interior of the washer extractor;
- d) pumping the washing liquid from the reservoir to the washer extractor interior;
- e) adding washing chemicals to the washer extractor interior;
- f) transmitting rinse water to the washing extractor interior at a rate of 0.35 to 0.6 gallons (1.33 and 2.3 liters) of water per pound (0.45 kg) of fabric articles within a selected time interval;
- and
- g) extracting liquid from the washer extractor after step “f”.
A washer extractor apparatus, comprising:
- a) a washer extractor for holding fabric articles to be washed in a washing liquid having an associated reservoir and a washer extractor interior;
- b) a reservoir having a flow line that enables transmission of washing liquid from the reservoir to the washer extractor interior;
- c) a pump that enables flowing of rinse fluid to the fabric articles at a volume of between about 0.5 to 2.0 gallons (2-8 liters) per pound (0.45 kg) of fabric articles for a selected time interval;
- d) wherein said pump is capable of transmitting water to the washer extractor at the rate of 0.35 to 0.6 gallons (1.33-2.3 liters) of water per pound (0.45 kg) of fabric articles within a selected time interval;
- and
- e) a flow line that enables extraction of liquid from the washer extractor.
A method of washing fabric articles, comprising the steps of:
- a) providing a reservoir of washing liquid;
- b) providing a washer extractor having an interior for holding fabric articles;
- c) placing fabric articles to be washed in the interior of the washer extractor;
- d) pumping the washing liquid from the reservoir to the washer extractor interior wherein the washer extractor interior has a liquid upper surface;
- e) controlling the liquid upper surface level with a weir that continuously discharges excess water from the washer extractor interior, said weir having a weir effluent;
- f) adding washing chemicals to the washer extractor interior;
- g) transmitting rinse water to the washing extractor interior at a rate of 0.35 to 0.6 gallons (1.33 to 2.3 liters) of water per pound (0.45 kg) of fabric articles within a selected time interval;
- and
- h) extracting liquid from the washer extractor after step “f′, wherein excess liquid that has been added in step “f” is discharged via the weir.
