Abstract
A sheet form fabric conditioner for use in a tumble dryer comprises a substrate carrying a fabric conditioning formulation exposed at the major surfaces of the sheet. The formulation forms a thin layer on each surface and the layers are embossed with channels. If these channels are visible after a drying cycle then sufficient conditioner remains for another cycle.
Claims5
A fabric conditioning product for the conditioning of fabrics in a tumble dryer during the dryer cycle of a fabric laundering operation, said product comprising a substrate in flexible sheet form and a layer of fabric conditioning formulation on at least one major surface of the substrate, said layer having an exposed surface area and said layer including at least one region occupying between about 5% and about 50% of said exposed surface area, which region, before use of the product in a tumble dryer, has a reduced constant depth such that the layer presents a visually perceivable uneven surface of sharply defined configuration, said fabric conditioning formulation having a softening point of between about 35.degree. C. and about 80.degree. C.
A process for manufacturing a fabric conditioning product, which process comprises the steps of:
- (i) providing a substrate in flexible sheet form;
- (ii) providing on at least one major surface of said substrate a layer of fabric conditioning formulation, said layer having an exposed area, and said fabric conditioning agent having a softening point between about 35.degree. C. and 80.degree. C.;
- and
- (iii) subjecting at least one region occupying between about 5% and about 50% of said exposed surface area, before use of the product in a tumble dryer, to heat to uniformly reduce the depth thereof such that the layer presents a visually uneven surface of sharply defined configuration.
