  • Publication number: 20260062502
    Abstract: A cellulose ester and/or cellulose ester fiber is produced from at least two different raw materials that each have recycled content from one or more from a waste materials. The resulting cellulose ester and/or cellulose ester fiber has higher recycled content than if only one of the raw materials used to make it had recycled content.

  • Publication number: 20250341030
    Abstract: A dichloromethane-free wet spinning process for producing cellulose triacetate fiber with a silk factor greater than 8.0. A dichloromethane-free cellulose triacetate dope comprising dimethylacetamide is wet spun into a coagulation bath which is controlled to a temperature ranging from 20° C. to 40° C. and comprising dimethylacetamide and water. A jet draw stretching ratio ranging from 0.3 to 1.4 is applied to the wet spun CTA fibers which may also be subjected to one or more post jet draw stretching steps. During drying, the CTA fibers are partially or completely shrunk. This process enables CTA fiber(s) having a silk factor greater than 8.0 to be produced without using dichloromethane and without the energy costs associated with other processes that requiring lower or higher coagulation bath temperatures.

  • Publication number: 20250011975
    Abstract: A dry spinning system and process are used to produce cellulose ester fibers. The process utilizes one or more of N,N-dimethylformamide, N,N-dimethylacetamide, dimethyl sulfoxide, or mixtures thereof as the dissolution solvent. The process minimizes or avoids discoloration of the fibers.

  • Patent number: 8906466
    Abstract: Methods of making esterified lignocellulosic materials and resulting compositions and articles are disclosed.
    Type: Grant
    Filed: June 17, 2010
    Date of Patent: December 9, 2014
    Assignee: Eastman Chemical Company
    Inventors: Jarvey Eugene Felty, Jr., Timothy L. Guinn, David Chris Spencer, John Michael Allen
  • Publication number: 20140065340
    Abstract: The invention provides flat-packed bundles of wooden boards in which at least some of the internal boards that contain acetylated wood possess certain moisture levels. The invention further provides flat-packed bundles of wooden boards in which at least some of the internal boards that contain acetylated wood have certain degrees of widthwise swelling. Although swelling can occur in several board dimensions, widthwise swelling provides a convenient measure. The invention also provides methods for moisturizing acetylated wood boards prior to assembling them into flat-packed bundles.

  • Patent number: 5792856
    Abstract: This invention provides certain carboxymethyl cellulose (CMC) esters of higher acids (e.g., CMC acetate propionate, CMC propionate, CMC acetate butyrate, and CMC butyrate). These new ether derivatives of cellulose esters exhibit solubility in a wide range of organic solvents, compatibility with a variety of resins, and ease of dispersion in a water-borne formulation and are useful in coating compositions as binder resins and rheology modifiers.

  • Patent number: 3972245
    Abstract: There is disclosed a Derailleur block comprising a sleeve adapted to be secured to a bicycle wheel hub, a sprocket carrier mounted on the sleeve with interposed ball races and free wheeling mechanism, and a number of sprockets having different numbers of teeth secured in axially spaced relationship on the carrier. At one end of the block there is a cone for adjusting the ball-race clearances in co-axial screw threaded engagement in the carrier, and in screw-threaded engagement with the protruding end of the cone, there is a lock nut. The lock nut serves not only to secure the cone after adjustment, but as an abutment for the sprocket assembly which is thereby readily removable. Both cone and lock nut are accessible for manipulation externally of the block.
