Definitions
- This invention in general relates to the production by the viscose process of cellulose filaments having low swelling values, high tearing and snarling resistance, and good crimping characteristics.
- the spinning bath contains 7.7 to 8.1% H 80, and 0.8 to 0.9% of zinc sulfate. It has a temperature of 47 C. After an immersion stretch of 18 cm. the threads are conducted by way of a godet or a glass rod, directly into a weakly acid, 96 to 98 C. second bath and there stretched by After the cutting, the fibers are Washed in a familiar manner and further processed.
- the tensile strength values of the fibers amount to 30.5 Rkm. (dry) and 19.9 Rkm. (Wet); the stretching values to 16.2% (dry) and 20.2% (Wet).
- the snarling resistance amounts to 7.4 Rkm.
- Example IV Beechwood sulfite pulp, after the addition of 2% by weight of methanol, based on the alkali cellulose, to the alkali cellulose, is sulfidized with 46%, on a dry basis of the cellulose, of carbon disulfide and dissolved to an 8.6/5.8-viscose.
- the viscose is spun from 1800/60 n-nozzles to a 1.5 denier type of 40 mm. staple length.
- the spinning bath contains 6.1 to 6.5% H SO and 0.8 to 0.9% of zinc sulfate. It has a temperature of 47 C. After an immersion stretch of 18 cm. the threads are directly conveyed, by way of a godet or a glass rod, into a weakly acid, 96 to 98 C. second bath and there stretched by 80%. After the cutting, the fibers are washed and further processed in a familiar manner. The tensile strength values of the fibers amount to 28.0 Rkm. (dry) and 18.7 Rkm.
- the present invention provides improvements in viscose processes for the manufacture of regenerated cellulose fibers having physical properties adapting the fibers for wider uses in manufacture of fabrics of regenerated cellulose fibers (rayons) and fabrics of blends of 60 regenerated cellulose fibers with natural fibers such as 6 cotton or wool or other synthetic fibers.
- the adaptation of fibers made according to the processes of this invention to these wider uses can be attributed to the improved tensile strength, the improved resistance to tear ing and snarling, and the inherent crimping of the filaments attained in the spinning and stretching operations.
