Abstract: 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.

Abstract: The invention relates to molded cellulose bodies, in particular fibers, filaments, directly spun nonwovens, films, or foams which have flame-resistant properties. The fibers and filaments can be further processed as textiles into yarns, wovens, knitted fabrics, and nonwovens. The molded bodies are produced from solutions of cellulose and melamine cyanurate or cellulose and crosslinked or partially crosslinked melamine resin particles in an organic solvent. The melamine cyanurate or the melamine resin particles provide the molded cellulose bodies with flame-retardant properties. The molded cellulose bodies made of cellulose and melamine cyanurate or melamine resin particles can further contain flame retardants, in particular flame retardants which act synergistically, in a particulate form. The obtained textile fibers and nonwoven materials have a soft touch and can be processed or finished as filaments or yarns on conventional textile machines.

Abstract: The invention relates to functional spunbonded fabrics incorporating fibers made from non-fusible polymers containing one or more functional additives. The fibers are interwoven and interlocked to form a firm fleece composite, have different lengths, and have aspect ratios above 1,000. The fibers have a mean diameter of 0.1 to 500 micrometres and diameter variations within a fiber and/or 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 spinning solution is extruded out of a spinneret, and the resulting strands are drawn in the longitudinal direction to form filaments or fibers, stabilized and laid down to form a fleece fabric.

Abstract: The invention relates to a molded body having a polymeric coating in which cladding material is prepared from a polymer solution; carrier material is guided through a feed channel and an outlet opening into a coating chamber, the feed channel traversing a container holding the cladding material; the cladding material is guided through a predefined gap into the coating chamber, and contact is effected between the cladding material and the carrier material to form a preliminary layer; the carrier material and preliminary layer are guided through an outlet opening into a relaxation zone; by setting the withdrawal of the carrier material via the outlet opening into the relaxation zone, the cladding material, the carrier material or both can be altered; and solvent is removed from the polymer layer. The molded bodies are preferably fibers, in particular bristles, such as brush or paint brush bristles.

Abstract: 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/m2 and 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.
