Abstract
The invention relates to a thermoplastic processible aminoplast resin, a method for its production and a fine fiber non-woven material as textile area of fibers from aminoplast resins, in particular duroplastic triazine resins, which have an average fiber diameter of 0.1 to 100 μm and between 1 and 1000 branching arms and between 1 and 300 branching points per square millimeter. The invention also relates to a method for production of duroplastic fine fiber non-woven material in which a melt of melamine resin is pressed through spinning nozzles and blown by the escaping hot air to fine fibers, the fine fibers are separated from the air stream and deposited to a non-woven material consisting of a tangled layer, a treatment with a media causing cross-linking and a neutralization step follows, and the fine fibers are glued to a non-woven material in a subsequent thermal after-treatment, whereat the thermal after-treatment comprises two steps.
