Claims (12)

1. Способ изготовления влагопоглощающих волокнистых изделий путем соединения между собой волокон с помощью самоотверждающейся фенольной смолы и под действием смачивающего агента, отличающийся тем, что применяют раствор связующего, содержащий самоотверждающуюся фенольную смолу и многоатомный спирт.1. A method of manufacturing moisture-absorbing fibrous products by combining fibers with a self-curing phenolic resin and under the action of a wetting agent, characterized in that a binder solution containing a self-curing phenolic resin and a polyhydric alcohol is used. 2. Способ по п.1, отличающийся тем, что раствор связующего содержит гликоль.2. The method according to claim 1, characterized in that the binder solution contains glycol. 3.
