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. The methods and compounds disclosed herein may be used to modify materials to improve properties such as resistance, grease repellency, soil resistance permanent press properties, and quickness of drying.
