Functional spunlaid fabrics incorporating fibers made from non-meltable polymers containing permanently one or more functional additives are provided. The fibers are entangled and interlocked to form a firm nonwoven composite, have different lengths, and aspect ratios above 1,000. The fibers have a mean diameter of 0.1 to 500 micrometres and diameter variations within a single fiber and among each other of at least 30%. The fibers contain more than 40 wt % of finely distributed functional additives in solid and/or liquid form. The spunlaid fabric is produced from a spinning solution containing the non-meltable polymer dissolved in a direct solvent and at least one functional additive. The spinning solution is extruded out of a spinneret, and the resulting strands are drawn in the longitudinal direction to form fibers, stabilized and laid down to form a nonwoven fabric with permanent functional properties. Exemplary spunlaid fabrics include clothing, technical textiles and filters.

Highly functional spunbonded fabric made from particle-containing fibres and method for producing same

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 &#x3bc;m 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.

The invention relates to a flat heater, which is used for applications in the range of heating voltages of up to 1000 V, produces attainable powers of up to 2 kW/mand is characterized by the fact that the electrical resistance required for the heating is formed by an electrically conductive cellulose nonwoven. Metallic contacts which are incorporated ensure the connection of the conductive cellulose nonwoven to a voltage source. Polymer films applied on both sides provide mechanical and electrical protection and prevent the ingress of moisture into the cellulose nonwoven.
