ABSTRACT:
Cellulose fibers are entrained in a gaseous medium and sized while entrained with a sizing material. The sizing material may comprise a nonaqueous solution of alkyl ketene dimer or other sizing material. Also, immersions of fibers in such a nonaqueous sizing solution is another approach for sizing fibers.
