Title: Washing method

Description:
FIELD OF THE INVENTION 
     The present invention is in the field of laundry. It relates to a method of laundering fabric in a laundry machine, in particular it relates to a method comprising a washing cycle and a rinsing cycle, wherein the washing cycle is divided into two sub-cycles having different detergent concentration and preferably different duration. The method provides outstanding cleaning and fabric maintenance. It is energy efficient in terms of time, heat and water usage. 
     BACKGROUND OF THE INVENTION 
     Laundering is a very complex art. When designing a laundering method the designer attempts to achieve good cleaning, fabric maintenance and at the same time improve the energy efficiency of the process. 
     The object of the present invention is to provide an improved method of laundering fabric in terms of cleaning, fabric maintenance and energy efficiency. 
     SUMMARY OF THE INVENTION 
     The present invention provides a method of laundering fabric in a laundry machine. 
     The method comprises the steps of:
         a) placing the fabric into a laundry machine and adding a detergent composition;   b) subjecting the fabric to a two-parts washing cycle having a first and a second consecutive sub-cycles, the first sub-cycle having a first washing liquor and the second sub-cycle having a second washing liquor wherein the first washing liquor is more concentrated (i.e. higher detergent concentration) than the second washing liquor and preferably wherein the duration of the first washing sub-cycle is longer than the duration of the second washing sub-cycle; and   c) rinsing the fabric.       

     The laundry machine can be of any type, automatic, semi-automatic, etc. 
     Preferably the method of the invention is performed in an automatic washing machine. The automatic washing machine can be a top loader or a front loader. Preferred for use herein is a top loader washing machine. 
     The detergent composition can be any detergent composition, in any physical form. Preferred for use herein are detergent compositions comprising catalytic ingredients. By “catalytic” ingredients is meant herein ingredients which constitute less than about 5%, preferably less than about 4% and especially less than about 1% by weight of the composition. Catalytic ingredients require a low level and provide a great deal of cleaning. Preferred catalytic ingredients for use herein are enzymes. 
     The first step of the method of the invention is to place the fabric into a laundry machine and to add a detergent composition. In the case of a top loader machine the detergent can be added in the drum. In the case of a front loader machine the detergent can be added through the drawer. 
     The second step of the method of the invention is to subject the fabric to a washing cycle. The fabric is subjected to agitation during the washing cycle. Water is not drained off during the washing cycle but only after the whole washing cycle has finished. The washing cycle of the method of the present invention requires at least about two washing sub-cycles, although it can have more than about two. The first sub-cycle involves a first washing liquor. The first washing liquor is more concentrated than the second washing liquor. It is preferred that the duration of the first sub-cycle is longer than that of the second sub-cycle. This specific washing cycle has a number of advantages over traditional washing cycles. Herein we are talking about one washing cycle having two parts and not two different washing cycles, i.e. the washing liquor of the first sub-cycle is not emptied before the second sub-cycle. Additional water is added in the second sub-cycle to the first washing liquor to form the second washing liquor. It has now been found that the specific washing cycle of the method of the present invention, provides better cleaning and fabric maintenance than two different washing cycles, and this is even so if the two different washing cycles use more water than the washing cycle of the invention. It is also better than if a shorter washing cycles is used and the water of the second sub-cycle is used to rinse the fabric. 
     The first sub-cycle facilitates the deposition of the detergent onto the fabric surface. The chemical cleaning is improved due to the high concentration of the detergent as compared to a traditional washing cycle. The amount of water in the first sub-cycle is low, this greatly helps with the chemical cleaning. Preferably the volume of water in the first sub-cycle is lower than that of the second sub-cycle. Thus the function of the first sub-cycle is to contribute as much as possible to detergent deposition and chemical cleaning, in particular stain and soil removal. The second sub-cycle preferably requires a higher volume of washing liquor than the first subcycle, this contributes to separation from the fabric surface of the soil removed from the fabric, this contributes to the avoidance of dinginess and building up from the removed soil. This plays an important role in terms of fabric maintenance. The volume of water of the second sub-cycle is usually such that allows the fabric to nearly freely float, this contributes to lifting of the soil that was removed from the fabric in the first sub-cycle. The two sub-cycles of the washing cycle seem to have a synergistic rather than an additive effect on cleaning and fabric maintenance. Preferably the duration of the first sub-cycle is longer than that of the second. 
     This is beneficial from a catalytic chemistry view point. For example, the enzymes have more time to act. This is even more beneficial if the washing takes place at ambient temperature, under this temperature enzymes are not degraded and can keep working for the whole length of the cycle. 
     In a preferred embodiment the concentration, expressed in grams per litres, of the detergent in the first washing liquor is at least about 5%, more preferably at least about 10% and especially at least about 15% higher than that of the second washing liquor. This facilitates fabric deposition that is translated in better cleaning due to the high concentration of the active ingredients of the detergent composition. Preferably the concentration of the detergent in the first washing liquor is at least about 0.2, more preferably about 0.3 and especially about 0.4 g/l. 
     In a preferred embodiment the volume of the second washing liquor is at least about 5%, more preferably at least about 10% and especially at least about 15% higher than that of the first washing liquor. As indicated before, this high volume of water contributes to the floating of the fabric that in turn contributes to a better soil lifting that is directly translated in better cleaning. 
     In a preferred embodiment the volume to weight ratio of the first washing liquor to the fabric is less than about 4:1 and the ratio of the second washing liquor to the fabric is greater than about 4:1. This particular setting provides good cleaning and fabric maintenance. 
     In a preferred embodiment the volume of the first washing liquor is at least about 10 litres, more preferably at least about 15 litres and especially at least about 20 litres. In a preferred embodiment the volume of the second washing liquor is at least about 12 litres, more preferably at least about 18 litres and especially at least about 25 litres. In an especially preferred embodiment the volume about 5 of the first washing liquor is from about 20 to about 40 litres and the volume of the second washing liquor is from about 23 to about 50 litres, this is preferably suitable for top loader machines. 
     Preferably, the rinsing of the fabric involves only one rinsing step, this being specially preferred from a water saving viewpoint. In other embodiments the rinsing involves at least two different steps, this is preferred from a fabric maintenance view point. 
     The duration of the washing cycle can vary. Preferably the duration of the first sub-cycle is at least about 10 minutes, more preferably at least about 15 minutes and especially from about 20 to about 40 minutes. Preferably the duration of the second sub-cycle is at least about 2 minutes, more preferably at least about 7 minutes and especially from about 5 to about 15 minutes. This has proved to be optimum for cleaning and fabric maintenance while being very energy efficient. Preferably the combined time of the washing and rinse cycle is below one hour. 
     The method of the invention is especially suitable for use at low, i.e., ambient temperature. 
     Preferably the detergent composition for use herein comprise enzymes, more preferably the concentration of enzymes in the first washing liquor is from about 0.01 to about 50 ppm, more preferably from about 0.05 to about 40 ppm. Compositions comprising a plurality of enzymes have been found preferred from a performance viewpoint. Also preferred are compositions comprising a fabric shading dye. The method of the invention provide excellent results even in the absence of bleach, thus in a preferred embodiment the detergent composition comprises enzyme and is free of bleach, this allows for a better working environment for the enzymes. In a preferred embodiment the detergent composition comprises surfactant, builders and enzymes and is preferably free of bleach.

Preferably the method of the invention takes place at ambient temperature. The fabric may be contacted to the water prior to, or after, or simultaneous with, contacting the laundry detergent composition with water. 
     Typically, the wash liquor is formed by contacting the laundry detergent to water in such an amount so that the concentration of laundry detergent composition in the wash liquor is from above about 0 g/1 to about 5 g/l, or from about 1 g/l, and to about 4.5 g/l, or to about 4.0 g/l, or to about 3.5 g/l, or to about 3.0 g/l, or to about 2.5 g/l, or even to about 2.0 g/l, or even to about 1.5 g/l. The method of laundering fabric may be carried out in a top-loading or frontloading automatic washing machine. In these applications, the wash liquor formed and concentration of laundry detergent composition in the wash liquor is that of the corresponding washing cycle. Any input of water during any optional rinsing step(s) is not included when determining the volume of the washing liquor. 
     The wash liquor may comprise about 60 litres or less of water, or about 50 litres or less, or about 40 litres or less, or about 30 litres or less, or about 20 litres or less, or about 10 litres or less, or about 8 litres or less, about 5 or even about 6 litres or less of water. The wash liquor may comprise from above about 0 to about 15 litres, or from about 2 litres, and to about 12 litres, or even to about 8 litres of water. 
     Typically from about 0.01 kg to about 2 kg of fabric per litre of wash liquor is dosed into said wash liquor. Typically from about 0.01 kg, or from about 0.05 kg, or from about 0.07 kg, or from about 0.10 kg, or from about 0.15 kg, or from about 0.20 kg, or from about 0.25 kg fabric per litre of wash liquor is dosed into said wash liquor. 
     Optionally, about 60 g or less, or about 50 g or less, or about 40 g or less, or about 35 g or less, or about 30 g or less, or about 25 g or less of the composition is contacted to water to form the wash liquor.

     Example 
     A top load automatic washing machine is loaded with 2 kg of fabric and 50 g of a detergent composition as detailed in the table below. The machine draws in sufficient water (25 litre) to dissolve the detergent and completely wet the load. The load is agitated for 30 minutes then additional water (5 litres) is added to allow the fabric to float and move more freely. Agitation continues (10 min) 
     The machine drains the water and spins the load to remove excess water. The machine re-fills to the higher water level (30 litres) and performs a single rinsing phase (10 minutes). The machine drains and spins the load
