  • Fiber pellets and processes for forming fiber pellets
    Publication number: 20040169306
    Abstract: Low moisture processed cellulose fiber pellets useful in the manufacture of cellulose fiber reinforced polymer products and materials, and an extruder-less process for forming such low moisture cellulose fiber pellets from wet processed cellulose fiber-based waste source materials. The cellulose fiber pellets include processed cellulose fibers and mixed plastics and/or inorganics such as minerals, clay, and the like, and have a moisture content of about 0.1 to 14% by weight. The extruder-less process includes the steps of drying, grinding and pelletizing in a manner capable of forming low moisture cellulose fiber pellets from wet processed cellulose fiber-based waste source materials having a moisture content of about 40-80% by weight.
    Type: Application
    Filed: March 4, 2004
    Publication date: September 2, 2004
    Applicant: CYTECH FIBER PROCESSING SYSTEMS, INC.
    Inventors: Jerry W. Crews, Darren Traub, Murray Wishengrad
