L* score is different than the second C.I.E. L* score.
Soft wipe comprising cellulose acetate
A soft wipe article is provided comprising a wet-laid sheet which comprises cellulosic fibers and cellulose ester staple fibers, wherein the cellulose ester staple fibers are present in an amount sufficient to provide the wet laid-sheet with a lower density and higher thickness at a given basis weight compared to a 100% Cellulose Comparative composition, when processed under similar conditions. The cellulose ester staple fibers can also provide the wet laid-sheet with a higher softness, while maintaining or increasing tear strength, compared to a 100% Cellulose Comparative composition, when processed under similar conditions.

METHODS AND SYSTEMS FOR PRODUCING BEADED POLYMERIC FIBERS WITH ADVANCED THERMOREGULATING PROPERTIES
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.
POLYOLEFIN FIBRES
