Abstract: In a method of manufacturing a laminate from at least two layers, a spun bonded nonwoven layer containing thermoplastic endless filaments, as a first layer, and a wetlaid nonwoven layer manufactured by the wet method with short staple fibers made of inorganic fibers (wetlaid nonwoven layer), as the second layer, are bonded together by a joint heat and pressure treatment. To make the wetlaid nonwoven layer, initially short staple fibers, thermoplastic binder, and possible other additives, suspended in water, are applied to a water-permeable substrate that holds back the other components and are dried to form a nonwoven layer. The dried wetlaid nonwoven layer, without further addition of binder, is combined with the spun bonded nonwoven layer before the heat and pressure treatment. A laminate of the invention is composed of at least two layers. A first layer is a spun bonded nonwoven layer containing thermoplastic endless filaments, and a second layer is a wetlaid nonwoven layer containing inorganic fibers.

Abstract: Dosing unit comprising a detergent and/or a bleaching agent contained in a sachet which entirely or partly consists of a sealable substrate and is provided with one or more seams that are sealed with a water-sensitive coating composition.The moment at which the sachet opens is to a great extent independent of the agitation and heating up behaviour of the (dish)washing machine. This is attained by using a coating composition comprisingan anionic and/or a nonionic water binding polymer anda cationic polymeric adhesive.
