  • Patent number: 10501876
    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.

  • Patent number: 9613230
    Abstract: The plug part (10) is connectable to a mating part (1), which is used as a connector of a device (50), to form a plug-in connection. The plug part (10) includes at least one non-volatile memory (13), a communication unit (15) and a microprocessor (14). A network having such plug parts (10) can be tested by means of a testing device, which is designed to generate test signals from information stored in the memory (13), which test signals can be laid on the cable wired leading out of the plug part (10) in order to generate measurement signals. The memory (13) preferably contains a list of permissible combinations of hardware and software versions, which can be compared with the current hardware and software combination of the device (50) in order to configure the device (50) and/or authorize the device (50) for normal operation.

  • Patent number: 8722779
    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 ?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.

  • Publication number: 20120215148
    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 spunbonded fabric is produced from a spinning solution containing the non-fusible 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 filaments or fibers, stabilized and laid down to form a fleece fabric. Exemplary spunbonded fabrics include clothing, technical textiles and filters.

  • Patent number: 8153940
    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.

  • Publication number: 20080203602
    Abstract: The invention relates to a method for producing duroplastic fine-fiber non-wovens, characterized in that: a) melts of reactive three-dimensionally cross-linkable, non-linear prepolymers are extruded by nozzles; b) the exiting melts are blown by means of hot air to form fine fibers; c) the fine fibers are separated by the flow of air and deposited to form a non-woven comprised of a fine-fiber weave; d) the non-woven is subsequently compacted, and; e) the non-woven is treated with a medium that initiates a three-dimensional cross-linking, and the fine fibers in the non-woven are inherently bonded and/or hardened in a subsequent thermal post-hardening. This enables duroplastic fine-fiber non-wovens to be economically produced that have both a high flame retardant effect as well as a high thermal protection, sound insulation and filtering capacity.

  • Patent number: 6670469
    Abstract: Process for producing regular porous pearl cellulose with a particle size in the range from 2 to 1,000 &mgr;m, comprising the steps: a) a cellulose having a degree of polymerisation in the range from 150 to 2,000 is dissolved in a solvent to form a solution of 0.5 to 25% by mass, b) the cellulose solution is finely divided and dispersed in a dispersant which is immiscible with said solution and has a viscosity in the range from 10 to 80,000 mPa·s, c) the dispersed solution particles are solidified to regular pearl particles by precipitating with a liquid precipitating agent miscible with the solvent (1) after cooling the dispersion to below the melting temperature of the cellulose solution and separating the frozen particles of the cellulose solution from the dispersant or (2) directly in the dispersion, and d) the pearl particles are separated from the liquid mixture of solvent, precipitating agent and possibly dispersant.
