Functionalizing the fiber material having multiple hydroxyl groups includes reacting the fiber material with a compound of formula I to obtain a functionalized fiber material, wherein X is the monovalent counter anion of the quaternary ammonium cation of formula I, and Hal is a halogen atom. Also provided are functionalized fibrous materials (eg, functionalized fibers comprising a moiety of formula II) prepared by any of the methods described herein, which have a free amine odor below the detection threshold or have an aversion score of about 3 or more Low free amine odor. The functionalized fibrous material can be dyed, and apparel-like articles can be made from the dyed functionalized fibrous material. |
