  • FIBER PRETREATMENT FOR IMPROVED NATURAL FIBER - POLYMER COMPOSITE FEEDSTOCK PRODUCTION
    Publication number: 20230242718
    Abstract: Provided are methods for preparing modified natural fiber composite feedstocks. In some embodiments, the presently disclosed methods include hydrolyzing agricultural fiber material, optionally soybean hulls, under conditions and for a time sufficient to remove some or all of the arabinose from the agricultural fiber material to produce an arabinose-deficient hydrolyzed product; hydrolyzing the arabinose-deficient hydrolyzed product under conditions and for a time sufficient to remove some or all of the xylose from the arabinose-deficient hydrolyzed product to produce a hydrolyzed fiber material; and combining a thermoplastic copolyester (TPC) with up to 35 wt. % by weight of the hydrolyzed material, whereby a modified fiber composite feed stock is prepared.
