A fluorine-free treating composition that includes Component A and Component B, wherein: 1. A method of treating a fibrous substrate in an amount sufficient to make the fibrous substrate water repellent , the method comprising applying to the fibrous substrate a fluorine-free treating composition comprising:Component (A) comprising one or more polymeric compounds derived from the polymerization of at least one (meth)acrylate monomer comprising at least one hydrocarbon group having from 1 to 60 carbon atoms and at least one isocyanate-derived group; andComponent (C), wherein Component (C) comprises one or more polycarbodiimide compounds.2. The method of claim 1 , wherein the fluorine-free treating composition comprises:from 1 wt-% to 99 wt-% of Component A, based on the total weight of Component A and Component C; andfrom 1 wt-% to 99 wt-% of Component C, based on the total weight of Component A and Component C.3. The method of claim 1 , wherein the one or more polymeric compounds of Component A are derived from the polymerization of at least one (meth)acrylate monomer having at least one of the following formulas:{'br': None, 'sup': 1', '2, 'sub': '2', 'R—OC(O)—C(R)═CH\u2003\u2003(Formula 0)'}{'br': None, 'sup': 1', '1', '2, 'sub': '2', 'R—NH—C(O)O-L-OC(O)C(R)═CH\u2003\u2003(Formula I);'}{'br': None, 'sup': 3', '1', '2', '4, 'sub': '2', 'R—X—C(O)NH-L-OC(O)C(R)═CH\u2003\u2003(Formula II); and'}{'br': None, 'sup': 5', '2', '3', '6, 'sub': '2', 'R—X—C(O)NH-Q-NHC(O)O-L-OC(O)C(R)═CH\u2003\u2003(Formula III);'}wherein:{'sup': 1', '3', '5, 'R, R, and Rare independently a hydrocarbon group having from 1 to 60 carbon atoms;'}{'sup': 2', '4', '6, 'sub': '3', 'R, R, and Rare independently H or CH;'}{'sup': 1', '2', '3, 'L, L, and Lare independently a branched or straight chain alkylene group having 2 to 10 carbon atoms, an arylene group, or a combination thereof;'}{'sup': 1', '2', '7', '7, 'Xand Xare independently O, S, —NH, or —N(R), wherein Ris a hydrocarbon group having 1 ...
