Abstract

The invention discloses a spinning technique used for producing viscose artificial fiber of deformed and flat monofilament in the spinning field. The procedures of spinning technique comprises the processes of gel-supplying, metering, filtrating, spinning, solidification bath, drafting, deacidification, strand silk forming; in the process of drafting, strand silk is directly drafted from a nozzle to a drafting roll assembly which comprises at least two couples of drafting rolls with different diameters; linear speed difference of the drafting rolls generates drafting force for drafting the strand silk; in the process of deacidification, the strand silk falls into a deacidification trough from the drafting rolls for deacidification by a mode of soaking and washing; in the process of forming strand silk, a wring-loading style winding mechanism is adopted for winding the strand silk. The technique is applicable to the production of deformed and flat monofilament which substitutes the synthesized fiber material that is hard for natural degradation, and meets requirements of using green, environment friendly material in domestic and foreign package material, artware and clothing decoration fields, etc. The technique is also applicable to the production of other deformed monofilament, conventional monofilament and multifilament products.

Description

technical field [0001] The invention belongs to the field of textiles, and in particular relates to a spinning process, in particular to a spinning process for producing special-shaped flat and monofilament viscose artificial fibers. Background technique [0002] Traditional semi-continuous centrifugal spun viscose filament spinning machine such as R535 spinning machine is composed of viscose conveying system, swing tube assembly, scraping acid, drafting disc, coagulation roller, acid removal roller, lifting frame and funnel, centrifugal cylinder and electric Spindle system and other components. The viscose conveying system is composed of viscose pipe and its supporting mechanism; the swing pipe assembly is composed of a metering pump connected in series with the rubber pipe, a filter sleeve, a curved pipe and a nozzle; above the double coagulation rollers, there are upper, The acid removal roller assembly is composed of two acid removal rollers installed below; on the lift...
