Claim 4:
5. A process for modifying a surface of a polymer-containing fabric, the process comprises:
providing a fabric comprising cellulose,
wherein the cellulose having, prior to being modified, exposed hydroxyl groups; and

reacting said fabric with a compound of formula (II):, where:
R1 and R2 are each independently vinyl, alkyl vinyl, propargyl, alkyl propagyl, allenyl, or alkyl allenyl;
R3 is an alkyl;
R5 is alkylene or carbonyl;
W′ is O; and
X1 and X2 are each independently —O—(CH2)n— or —S—(CH2)n—, where n is independently with respect to X1 and X2 an integer of 1 to 4;
in the presence of a reaction medium comprising an amine-containing organic compound in a polar aprotic solvent, so as to form an ester linkage or an ether linkage that binds the compound of formula II to the fabric, wherein the ester linkage and the ether linkage are each a reaction product of W and at least one of the exposed hydroxyl groups of the cellulose.
