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.
