The precise nature of these additional components, and levels of incorporation thereof, will depend on the physical form of the textile benefit composition and the nature of the operation for which it is to be used and applied. Useful adjunct materials may include, but are not limited to, bleach activators, surfactants, builders, dye transfer inhibiting agents, dispersants, enzymes, and enzyme stabilizers, catalytic metal complexes, polymeric dispersing agents, clay and soil removal/anti-redeposition agents, brighteners, suds suppressors, dyes, perfumes, structure elasticizing agents, fabric softeners, carriers, hydrotropes, processing aids and/or pigments.
Processes of Making Textile Benefit Compositions
The skilled artisan can produce the textile benefit compositions of the present invention by following (he teaching contained herein and in the examples as such compositions may be made by combining the requisite materials.
Commercial quantities of such textile benefit compositions can be made using a variety of reaction vessels and processes including batch, semi-batch and continuous processes. Such equipment may be obtained from a variety of sources such as Lodige GmbH (Paderborn,
Germany), Littleford Day, Inc. (Florence, Kentucky, U.S.A.), Forberg AS (Larvik, Norway), Glatt Ingenieurtechnik GmbH (Weimar, Germany), Niro (Soeborg, Denmark), Hosokawa Bepex (Minneapolis, Minnesota, USA).
Method of I Ise
An article may be ireated with any of Applicants' benefit compositions or mixtures thereof:
Typically, an article comprising a stain repellant treatment is contacted with the benefit composition in neat form or during a cleaning or washing process. Contact methods include padding wiping, spraying and washing.
Useful equipment for practicing the method disclosed herein includes sponges, cloths, spray bottles and washing units and containers such as washing machines. Treatment methods may comprise contacting the article before during or after a washing step that may optionally include rinsing and/or a drying step.
Treated Articles
Textile products having enhanced and/or durable stain repellency properties may be made by treating said textile products with Applicants' benefit compositions. Treatment methods include the methods disclosed in the present, specification.
