  • Process for the preparation of regenerated cellulose filaments
    Patent number: 5997790
    Abstract: The disclosure describes a process for the preparation of regenerated cellulose filaments from an anisotropic solution including cellulose formate, phosphoric acid, and formic acid in which the formed cellulose formate filaments are dried to a moisture content of not more than 15% prior to regeneration and after regeneration the filaments are washed and dried under low tension. In this manner cellulose multifilament yarns of high breaking load and high elongation at break can be obtained, which in addition have a very regular linear density.
