Abstract

The invention discloses a heterotype flat artificial silk spinning machine which is applicable to the production of hererotpe flat, non-twist and large fibrous artificial silk. The machine comprises a gel-feeding pipe, a metering pump, an angle pipe, an acid bath trough, a drafting mechanism and a deacidification mechanism. The machine is characterized in that: the drafting mechanism comprises a drafting roll assembly, the lower end of which is provided with a deacidification trough, and the terminal of the deacidification trough is provided with a wring-loading style winding mechanism. The machine is applicable to the production of heterotype flat monofilament which substitutes the synthesized fiber material that is hard for natural degradation, and meets the requirements of using green and environment-friendly material in domestic and foreign package material, artware and clothing decoration fields, etc. The machine is also applicable to the production of other heterotype monofilament, conventional monofilament and multifilament products. By adopting the technique of the invention, the fibrousness range of the artificial silk can reach 167dtex / / 1F-6667dtex / 1F.

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...
