    Abstract: Disclosed is a process for producing a crimp-bonded fibrous cellulosic laminate. The process includes the steps of: 1) providing at least two superposed plies of a fibrous cellulosic material; 2) passing the superposed plies through a crimp roll arrangement including a rotating crimp element and a rotating anvil element; and 3) applying a pressure load against the rotating elements sufficient to crimp bond the fibrous cellulosic material plies into a laminate. The crimp element has protruding members configured in a discontinuous pattern aligned on an axis that is parallel to the cross-machine direction to provide a substantially continuous uniform area of localized surface contacts between the rotating crimp and anvil elements across the width of the plies. Also disclosed is an overall crimp-bonded fibrous cellulosic laminate and an apparatus for crimp-bonding multiple superposed plies of a fibrous cellulosic material.

  • Patent number: 4193252
    Abstract: In a method of making carbon or graphite yarn, a bundle of single ply precursor yarns is knit into an elongated fabric to facilitate subsequent processing of the yarns. The elongated fabric is pretreated to facilitate carbonization thereof such as by being advanced in the direction of elongation thereof through a cleaning process. Thereafter the yarns remain in the form of the fabric to facilitate processing thereof through at least a carbonization step. The carbonization step may be accomplished by winding the elongated fabric onto skeins to a desired extent and then severing the fabric, following which the skeins are disposed in a carbonizing oven to at least partially carbonize the yarns. Thereafter, the fabric length on each skein may be deknitted, and the resulting bundle of single ply yarns is twisted to form a multi-ply yarn which is then fired to substantially raise the percentage of carbon in the yarns and then graphitized.
