Definitions

• the invention relates to a process of ironing fabrics.
• the iron contains a refill cartridge, which contains a concentrated ironing aid.
• the concentrated aid is then diluted with water in the iron before it is provided to the fabrics during ironing.
• the aid comprises a nonionic silicone containing surfactant.
• the present invention relates to the ironing of fabrics. It is well-known that ironing of fabrics is conveniently achieved with ironing aids. Ironing aids are products, which assist in the ironing of fabrics, in one way or the other, mainly by enhancing the glide of the soleplate of the iron on the fabrics. It is also known that ironing aids can be provided by means of standalone products, typically sold in aerosols or manual sprayers. It is also known that ironing aids can be provided "through-the-iron", but such executions are much less common, on a commercial scale. And amongst those executions, a preferred one is one where the ironing aid is provided to the iron in the form of a concentrated product, and the concentrated product is diluted with water from a water tank in the iron.
• the concentrated product would then be provided to the iron by means of cartridge refills.
• a refill will last a long time because it contains a concentrated product, and thus the iron can use a high dilution factor.
• Such an iron has been disclosed in WO99/27176.
• the invention solves this problem by proposing the use of nonionic silicone containing surfactants. Concentrated compositions of such surfactants indeed meet the aforementioned objects.
• the present invention encompasses a process of ironing fabrics with an iron and an ironing aid product.
• the ironing aid product is provided to the iron as a concentrated product.
• the concentrated product is diluted with water in the iron and then provided from the iron to the fabrics.

• the article of manufacture comprises a container and content inside the container, and usage instructions.
• the content is the ironing aid product.
• the usage instructions instruct that the ironing aid product must be provided to an iron in which the ironing aid product will be diluted with water.
• the usage instructions may be printed on the container or provided separately.
• There may be a single container with its content, or several containers with their content provided with one set of instructions.
