Abstract: This invention is directed to treatment preparations useful for the permanent or substantially permanent treatment of textiles and other webs to provide tear and abrasion strength and softness to durable-press garments. The preparations comprise a softener (a “resin-reactive modifier”) durable to repeated laundering used in conjunction with a durable-press resin, to increase the comfort and lifetime of durable-press garments. The resulting durable-press/softener preparation is substantially permanently attached to the web and provides improved softness and tear/abrasion strength retention within and/or on the textile or web fiber structure while retaining the durable-press properties of the resin. This invention is further directed to the yarns, fibers, fabrics, textiles, finished goods, or nonwovens (encompassed herein under the terms “textiles” and “webs”) treated with the textile-reactive durable-press/softener preparation.

Abstract: The present invention is directed to polymeric treatment preparations for textiles and other fibrous substrates that impart water and oil repellency to fibers, yarns, textiles, or other fibrous substrates. More particularly, this invention comprises an aqueous solution, emulsion or suspension of (a) a fluorinated polymer that contains reactive groups that can complex with metal atoms that have a formal charge of 2 or greater, and (b) one or more metal atoms that have a formal charge of 2 or greater. The invention is further directed to the process for treating fibrous substrates with textile preparations in one step that provide water/soil repellency that is durable to repeated cleanings and to abrasion. This invention is further directed to the yarns, fibers, fabrics, textiles, webs, finished goods, or nonwovens (encompassed herein under the terms “textiles” and “fibrous substrates”) treated with the textile-reactive water- and soil-resistant preparation of the invention.

Abstract: The present invention is directed to a copolymer capable of forming a water- and oil-repellent agent that enables binding to textiles and other materials without the production of formaldehyde. The copolymer according to the present invention comprises a) a fluoroaliphatic radical-containing agent, (b) stearyl (meth)acrylate; (c) a chlorine-containing compound; and (d) a monomer selected from those that contain an anhydride functional group or are capable of forming an anhydride functional group. The present invention further provides a water and oil repellency-imparting composition for fibrous and other substrates, the composition comprising the above copolymer together with a catalyst, such as sodium hypophosphite, for forming anhydrides from the acid-containing monomers in the copolymer. The composition can further optionally comprise other additives such as, e.g., poly(acrylic acid); an extender; a softener; an antioxidant; a surfactant; and/or a plasticizer.

Abstract: Provided are compounds and methods for modifying a material to change properties of the material, as well as a variety of products obtained using the methods. The material which is modified may be, for example, a carbohydrate, and the modifiable functional groups on the material may be hydroxyls. Multifunctional molecules for use in modifying the surfaces of materials such as textile fibers, yarns and other fabrics made of or, including cotton, wool and nylon, are provided. The multifunctional molecules can include hydrophobic regions and/or hydrophilic regions. The multifunctional molecules also may include binding functional groups that permit either non-covalent or covalent binding to the material being modified, thus permitting the multifunctional molecule to form a non-covalent or covalent coating on the material.
