METHOD AND LINE FOR PRODUCING TAPE FROM BAST-FIBERS

摘要

FIELD: textile industry. SUBSTANCE: method involves preparing bast-fibers for spinning in single-pass spinning system by loosening, cleaning, mixing and tightening; breaking bast-fibers by loosening in compressed state; forming web; providing additional breaking of long fibers during tightening. Web is formed by aerodynamic method, with web thickness being simultaneously regulated. Bast-fibers may be mixed with chemical or other kinds of filaments in the form of loosened flows or fibrous tapes. EFFECT: simplified method and construction by reduced line. 12 cl, 2 dwgu
