Modified textile and other materials and methods for their preparation

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. In one embodiment, a material comprising one or more modifiable functional groups is reacted with an activated hydrophobic acyl group in the presence of a hindered base, thereby to covalently attach the hydrophobic acyl group to the modifiable functional groups on the material. The material which is modified may be, for example, a carbohydrate, and the modifiable functional groups on the material may be hydroxyls. For example, materials such as cellulose may be modified by reacting it with an acid chloride or acid anhydride including a hydrophobic acyl group, in the presence of a hindered base, such as tripentylamine, to attach the hydrophobic acyl groups to the hydroxyls on the cellulose, thereby to increase the hydrophobicity of the cellulose. The methods and compounds disclosed herein may be used to modify materials to improve properties such as resistance, grease repellency, soil resistance and permanent press properties.
