FIELD: chemistry. ^ SUBSTANCE: non-formaldehyde-containing curable aqueous composition contains polyvinyl alcohol combined with starch or modified starch or sugar, a multi-functional cross-linking agent and, optionally, a catalyst. The cross-linking agent is non-polymeric polyaldehyde, non-polymeric polyacid, salt thereof or anhydride. Nonwoven articles are obtained by bringing the composition into contact with fibrous components. Further, the mixture is cured to obtain a hard thermoset polymer. ^ EFFECT: composition ensures excellent strength and water resistance of the cured nonwoven article. ^ 22 cl, 4 tbl, 15 ex |
