| abstract |
The present invention relates to a thermoplastic cellulose acetate propionate composition for melt molding, comprising a component having a low environmental load, comprising a cellulose acetate propionate, which is a biomass-based material, as a main component. Provided is a thermoplastic cellulose acetate propionate composition fiber which is excellent not only in degree characteristics but also in uniformity of fineness. The composition comprises 80 to 95% by weight of cellulose acetate propionate and 5 to 20% by weight of a fatty acid ester having a molecular weight of 250 or more selected from glycerin and / or diglycerin, and has a loss on heating at 220 ° C. A thermoplastic cellulose acetate propionate composition for melt molding and a fiber comprising the same, wherein the melt viscosity at 220 ° C. and 1000 sec −1 is 20 to 200 Pa · sec.
