PROBLEM TO BE SOLVED: To provide non-fluorinated compositions that provide water repellency and optionally stain release for textiles， with performance results comparable to fluorinated treating agents. SOLUTION: The present invention concerns an aqueous composition comprising at least one hydrophobic compound having at least one linkage of formula I， -NHC(O)-X-. The linkage of formula (I) composes 30 to 100 mol% of the total urethane linkages in the hydrophobic compound. In the formula， X is the residue of a cyclic or acyclic sugar alcohol in which at least two residues are substituted with -R 1， -C(O)R1， or -(CH2CH2O)n(CH(CH3)CH2O)mC(O)R1. In the formula， each n is independently 0 to 20; each m is independently 0 to 20; m+n is greater than 0; each R1 is independently a linear or branched alkyl group having 5 to 29 carbon atoms.SELECTED DRAWING: None
所要解决的技术问题：提供一种非氟类组合物，可赋予纺织品拒水性及任选的防污易去污性能，其性能效果可与氟化处理剂相媲美。技术方案：本发明涉及一种水性组合物，其包含至少一种疏水化合物（hydrophobic compound），该疏水化合物带有至少一个式I所示的连接键：-NHC(O)-X-。式I所示的连接键在该疏水化合物的总氨基甲酸酯键（urethane linkages）中占30 mol%至100 mol%。其中，X为环状或无环糖醇（sugar alcohol）残基，且该残基中至少两个位点被-R¹、-C(O)R¹或-(CH₂CH₂O)ₙ(CH(CH₃)CH₂O)ₘC(O)R¹取代。式中，各n的取值独立为0至20；各m的取值独立为0至20；且m与n之和大于0；各R¹独立为含5至29个碳原子的直链或支链烷基（alkyl group）。附图说明：无
