<p>// POWDERED CLEANING COMPOSITION A powdered cleaning composition containing a particulate polymeric material, an inorganic salt adjuvant and an aqueous or organic fluid component. The present invention relates to dry type cleaning compositions and in particular to dry type cleaning compositions which are especially useful for cleaning textile fabrics such as pile fabrics. Liquid cleaning compositions, such as rug and upholstery shampoos have long dominated the market for textile cleaning products. Such liquid compositions, however, are generally recognized to suffer from a wide range of significant disadvantages, such as their tendency to cause shrinking, wicking, matting, etc. Such compositions, furthermore, tend to provide sticky, tacky deposits in the form of detergent residues on the treated fabric substantially increasing the resoiling tendency of the fabric. Application of liquid cleaning compositions to textile substrates such as carpeting may also require protracted drying times prior to resumption of use of the fabric. This required drying time of course may prove to be very inconvenient when the fabric is a carpet and where the carpet is, for instance, in a public thoroughfare as would be the case with commercial establishments such as office buildings, theaters, etc. Because of the foregoing, will-pecognized disadvantages associated with the use of liquid cleaning compositions, substantial efforts have been directed to the development of "dry"</p> |
