摘要： The present invention provides a meltblown wetlaid method for producing non-woven fabrics with anti-mildew, anti-bacteria and deodorizing capabilities from natural cellulose. The method comprises selecting wood pulp as raw material and using N-methylmorpholine N-oxide (NMMO) as dissolving solvent and 1,3-phenylene-bis 2-oxazoline (BOX) as stabilizer to form mixed cellulose mucilage as well as using modified and nano-miniaturized natural chitosan as additive for blending and dissolution to form cellulose dope. By meltblown method, the dope is extruded out of spinnerets to form filament bundle, then by ejecting mist aerosol of water, the filament bundle is coagulated with regeneration. After post treatments of water rinsing, hydro-entangled needle punching, drying, winding-up and the like having been orderly applied, then final product for nonwoven fabric of continuous filament with anti-mildew, anti-bacteria and deodorizing capabilities is produced.

摘要： Disclosed is a continuous preparation method of cellulose fibers, in which a forming tension of 0.1 to 1.9 cN/dtex is applied to a fine solution stream obtained by extrusion through a spinneret plate and air gap cooling, then the fine solution stream is fed into a coagulating bath at a speed of 80 to 1000 m/min, a traction tension of 0.075 to 1.5 cN/dtex is continued to be applied to washed fibers in a water washing system behind the coagulating bath, and finally, the washed fibers are fed into a post-treatment system for continuous and efficient spinning of finished fibers at a speed of 80 to 1000 m/min.

摘要： A network of microfibers are fabricated with a core-shell construction from sustainable materials, where the core includes a phase-change material, such as coconut oil, and the shell includes a biomass, such as cellulose. The microfibers are made via a wet-wet electrospinning process utilizing a coaxial spinneret with an inner conduit and an outer conduit. The biomass and the phase-change material are coaxially extruded into a coagulation bath including a mixture of ethanol and water. The collected microfibers exhibit a beaded structure of PCM aggregates and biomass connecting regions between the aggregates and are effective to aid in the thermoregulation of the immediate environment surrounding the network. The microfibers are suitable for use in a variety of sustainable products such as wearable thermoregulating textiles, wall/ceiling panels, insulation, packaging material, and more.
