Abstract
Fabric conditioning articles for use in treating fabrics in a laundry dryer. The articles comprise a flexible substrate and a fabric conditioning composition, wherein the fabric conditioning composition is distributed unevenly on the substrate so as to form a visual contrast between areas containing relatively high amounts of conditioning composition and areas containing either no conditioning composition or relatively low amounts thereof.
Claims17
An article suitable for conditioning fabrics in a laundry dryer, said article comprising a flexible woven or nonwoven web in sheet form having disposed thereon a fabric conditioning composition, wherein the fabric conditioning composition is unevenly distributed on the substrate in areas of high concentration of fabric conditioning composition per unit area of substrate and areas of low concentration of fabric conditioning composition per unit area of substrate so as to produce a visual contrast between said high concentration and low concentration areas, wherein the portion of the fabric conditioning composition in the areas of high concentration contains from about 0.05% to about 10% based on the total weight of fabric conditioning composition in said areas of high concentration, of a pigment which accentuates the visual difference between the portion of fabric conditioning composition in the areas of high concentration and the portion of the fabric conditioning composition in the areas of low concentration, wherein the weight per unit area of composition in the high concentration areas is at least about 1.25 times the weight per unit area of composition in the low concentration areas, and wherein the total weight ratio of fabric conditioning composition to substrate is from about 0.5:1 to about 5:1.
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 having two opposite faces and a layer of fabric conditioning formulation completely covering at least one major surface of at least one face of the substrate, said layer having an exposed surface area and said layer including at least one region occupying between about 40% and about 95% 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 which provides a guide to the amount of formulation remaining on the product after use, said fabric conditioning formulation having a softening point of between about 38.degree. C. and about 68.degree. C.
