Benefits of technology

[0006]The present invention is directed to a method of treating fabrics in a dryer. The method is suitable for the treatment of wet and dry fabrics. The method comprises the steps of placing fabrics into the dryer, applying a liquid composition onto the load and drying the fabrics. The composition can be delivered onto the load before, during and / or after the drying of the fabrics. The composition comprises a solvent and active ingredients. The composition does not become sticky during use, this avoids lint build up and optimizes the amount of active ingredients that goes onto the fabrics.
[0012]In a preferred embodiment, the composition of the method of the invention is delivered in the form of spray. This contributes to uniform distribution of the composition onto the treated fabrics.

Problems solved by technology

The small droplets of the spray can be carried by the air flow in the dryer, the droplets would eventually collide with parts of the dryer making the surfaces of the dryer sticky.
The lint build up would cover the body of the tumble dryer and it could block internal parts, such as air ducts and filters, impairing the efficiency of the tumble dryer.
An additional problem found with existing compositions is that the compositions stick to parts of the dryer and thereby reduce the amount of treatment composition delivered to the fabrics.

[0096]The Maximum Stickiness of the exemplified treating composition is 1,200 Force (g). A fabric load is treated with 100 ml of the exemplified composition, the load is placed in a dryer with a spray delivery system. The composition provides excellent perfuming of the load and does not produce lint build up.

Abstract

A method of treating wet or dry fabrics in a dryer the method comprises the steps of placing the fabrics into the dryer, delivering a liquid composition onto the fabrics and drying the fabrics, the composition comprising a solvent and active ingredients wherein the active ingredients have a Maximum Stickiness of about 2500 Force (g) as measured under the conditions defined herein.

Description

CROSS REFERENCE TO RELATED APPLICATION[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 325,496, filed Apr. 19, 2010.TECHNICAL FIELD[0002]The present invention is in the field of fabric treatment. In particular, it relates to a method of treating fabrics in a dyer comprising the step of delivering a composition onto the fabrics, the composition comprising a solvent and low stickiness active ingredients.BACKGROUND OF THE INVENTION[0003]Traditionally, tumble dryers have been used exclusively to dry wet items. Tumble dryers can also be used to treat fabrics. Treatments include refreshment, perfuming, softening and conditioning of the fabrics. Treatments of fabrics are usually performed in the presence of compositions especially designed to be used in a dryer.[0004]It has been found that compositions for use in a tumble dryer can contribute to the build up of lint. This lint build up is especially acute in cases in which the composition is sprayed into the...
