Title:
MELT SPINNING OF BLENDED CELLULOSE ACETATE BUTYRATE FIBERS
Document Type and Number:
WIPO Patent Application WO/2023/183649
Kind Code:
A3
Abstract:
Methods of preparing fibers comprising cellulose esters are described. The fibers include bicomponent core-sheath fibers where the core comprises one or more cellulose esters and the sheath comprises a polyolefin prepared by co-extrusion of mixtures comprising a cellulose ester and mixtures comprising a polyolefin, as well as substantially solid body fibers prepared by melt-spinning a mixture comprising one or more cellulose ester and a meltable solvent. Also described are fibers comprising cellulose esters, e.g., the fibers prepared by the disclosed methods, and related articles, such as textiles, clothing, synthetic fibers, and faux fur. The fibers can include colorants (e.g., colorants derived from natural materials) and/or flame retardants.
