Problem to be Solved: To provide an elastic nonwoven fabric with a good elasticity, adequate strength under elongation, good antiblocking property and favorable feeling, suitable for fiber products, at low cost, as well as fiber products using the same. Solution: An elastic nonwoven fabric comprising long elastomeric fiber and nonelastomeric fiber in a weight ratio within a range from 50/50 to 95/5, which has an elongation recovery rate of the elastic nonwoven fabric after 50% elongation equal to or higher than 70%, and a resistance to peel two sheets of the nonwoven fabric apart equal to or lower than the strength of the fabric under 50% elongation; as well as fiber products using the same.

Elastic nonwoven fabric and fiber products manufactured therefrom

Provided are: an addition polymer of fluorosilsesquioxane (a) having one addition polymerizable functional group or an addition copolymer of the fluorosilsesquioxane (a) having one addition polymerizable functional group and an addition polymerizable monomer (b); a coating film including the polymer or the copolymer; and an addition copolymer of the fluorosilsesquioxane (a) having one addition polymerizable functional group and organopolysiloxane (c) having an addition polymerizable functional group, or an addition copolymer of the fluorosilsesquioxane (a) having one addition polymerizable functional group, the organopolysiloxane (c) having an addition polymerizable functional group, and the addition polymerizable monomer (b).
