Definitions
- the present invention is in the field of laundry.
- it relates to a method of industrial or institutional laundry for a polyester load using a silicone suds suppressor during the wash process.
- detergents for household (or home) and professional (including institutional and industrial) laundries are similar, detergents for large-scale institutional or industrial use generally differ insofar as they must be designed to meet the special circumstances associated with laundry on an industrial scale and/or in an institutional context. Contrary to home laundry, professional laundries have to deal with large volumes of textile items and require therefore completely automatic processing with microprocessor-controlled machines and dosing units.
- the length of the washing process differs from that of home laundry and in some cases the washing is performed with soft water. Soil levels can be significantly lower in certain types of loads of professional laundry (for example towels and bed linen in a hotel which have minimal use and soiling before being re-washed) than in household laundry and the loads and the machines are considerably bigger.
- the composition of the loads is more uniform, in terms of both, types of fabrics and soils. For example a typical commercial laundry load will consist of only towels, only bed linen or only table linen
- Soft water also promotes sudsing. Under these circumstances, it is difficult to perform a good cleaning.
- Fatty acids or fatty soaps are commonly used as suds suppressors in laundry. They rely on the presence of water hardness ions to work. When water hardness ions are present they can form salts which can disrupt the suds. If there are no water hardness ions, as the case is with soft water, then the soap might even cause additional suds. It has been found that if a load of polyester is washed in soft water, using a normal amount of detergent, the level of suds can be so high that it can overflow the machine, this seems to be worse when the level of soil is low.
- a method of cleaning a polyester load in a professional laundry machine comprises subjecting the load to main-wash, rinse and optionally pre-wash cycles and wherein the method comprises the step of contacting the load with an aqueous wash liquor containing a detergent composition comprising a silicone suds suppressor.
- polyester load is understood a load comprising at least about 50%, preferably at least about 60%, more preferably at least about 80% and more preferably at least 95% by weight of the load of polyester items.
- the level of anionic surfactant is greater than 10%, more preferably greater than 15% and especially greater than 20% by weight of the detergent composition. This provides an outstanding cleaning over a great range of soils.
- the detergent composition preferably comprises non-ionic surfactant and anionic surfactant.
- the level of anionic surfactant is higher than the level of non-ionic surfactant, by "higher” is herein meant that the level of anionic surfactant is at least 1% by weight more than the level of non- ionic surfactant, preferably at least 5%, more preferably at least 15% and especially at least 20%.
- the level of non-ionic surfactant is less than 10% by weight of the detergent composition.
- the method of the invention also allows for flexibility in terms of detergent formulation.
- Polyester with low level of soil and new polyester items can be even more prone to sudsing than highly soiled items.
- the method of the invention performs very well even in the case of loads with low level of soil (typically towels or bed linen) or new items.
- low soiled items is herein understood items free from visible stains.
- new items is herein understood items that have not been subjected to a washing process.
- the liquor of the method of the invention preferably the liquor of each cycle, has a hardness, i.e., Ca and Mg ions concentration, of less than about 1, preferably less than about 0.5 and especially less than about 0.2 mmoles/litre.
- the method of the invention involves the step of heating the cleaning water using steam, in particular steam injection.
- Preferred suds suppressor for use herein is a polydimethlysiloxane compounded with silica. CM3373/SK
- the wash liquor preferably the wash liquor of the main wash, has a pH of from about 7 to about 10, preferably from about 8 to about 9, as measured at room temperature (20C) this allows not only for good cleaning but also for good care of the washed articles.
- the detergent composition comprises anionic surfactant, preferably in a level of at least 10%, more preferably at least 12% by weight of the detergent composition, and at least 50%, preferably at least 70% and more preferably at least 80% by weight of the anionic surfactant is an alkyl benzene sulfonated (LAS).
- anionic surfactant is an alkyl benzene sulfonated (LAS).
- LAS alkyl benzene sulfonated
- the method of the invention comprises the step of contacting the load with a soil release polymer, in any of the wash cycles, preferably during the main-wash or a rinse cycle.
- a soil release polymer is added as part of an additive rather than as part of a detergent composition. This not only obviates the process challenges found to make the soil release polymer part of a base detergent but also eliminates the interaction between some of the base detergent ingredients and the polymer and gives flexibility in terms of dosing.
- the present invention envisages a method of professional laundry of a polyester load.
- the method involves contacting the load with a detergent comprising a silicone suds suppressor.
- the method provides improved cleaning. It has been found that the problem of high suds is more acute in the case of a load with low level of soil, ie. a load with less than 10 g of soil per kilogram of load, preferably with less than 5 g of soil per kilogram of load.
- the polyester load used in the method of the present invention is a load with low level of soil.
- Institutional laundry refers to textile washing operations usually run in business sites, normally referred to as On-Premise or In-House Laundry Operations. Typical businesses can be for instance hotels, restaurants, care homes, hospitals, spas, health or sport clubs, schools, and similar institutions.
- Industrial laundry refers to textile washing operations carried out in dedicated places typically for the above businesses. CM3373/SK
- professional laundry machine is herein meant a laundry machine which a capacity higher than 8 kg, preferably higher than 15 kg and more preferably higher than 25 kg of dry laundry.
- front load which operate in a batch mode or tunnel washing machines that operate in continuous mode.
- the professional laundry machines for use herein, in the case of front load have a drum volume of at least about 0.15 m 3 , preferably at least 0.2 m 3 , more preferably at least 0.3 m 3 and especially at least 0.5 m 3 .

- silicone antifoam compounds are the combinations of polyorganosiloxane with silica particles commercially available from Dow Corning, Wacker Chemie and General Electric. CM3373/SK
- Silicone suds suppressors are typically utilized in amounts up to about 2% by weight of the detergent composition, although higher amounts may be used. This upper limit is practical in nature, due primarily to concern with keeping costs minized and effectiveness of lower amounts for effectively controlling sudsing. Preferably from about 0.01 % to about 1 % of active silicone suds suppressor is used, more preferably from about 0.05% to about 0.5% by weight of the detergent composition.
