A spinning and drawing combination machine for splitting and master filaments

Abstract

The invention discloses a split fiber mother filament spinning and drafting combined machine. The machine comprises an extrusion device, a melt pipe system, metering pumps, a spinning device, a cooling device, a channel component, an oiling device, a guide filament drafting device and a winding device which are arranged in sequence according to a production process; the cooling device comprises afirst-stage side air blowing cooling unit and a second-stage side air blowing cooling unit which are arranged in sequence according to the production process; the air volume of the first-stage side air blowing cooling unit is greater than that of the second-stage side air blowing cooling unit, and the air temperature of the first-stage side air blowing cooling unit is smaller than that of the second-stage side air blowing cooling unit. According to the provided split fiber mother filament spinning and drafting combined machine, through arrangement of the first-stage side air blowing cooling unit and the second-stage side air blowing cooling unit and reasonable setting of the temperature and air speed, tows are effectively cooled in the first-stage side air blowing cooling unit and the second-stage side air blowing cooling unit and solidified uniformly, and the quality of the tows of split fiber mother filaments is improved.

Description

technical field [0001] The application belongs to the technical field of spinning machinery and equipment, and in particular relates to a combined spinning and pulling machine for splitting and master silk. Background technique [0002] Monofilament is a single filament with a small linear density (denier), and the monofilament denier (dpf) is 22-33dtex. It has the characteristics of high technology, high efficiency, and high added value. Because the clothing material made of monofilament has many good properties, such as good drapability, translucent hazy effect, lightness and softness, etc., it can be used to weave flap fabrics for civilian use, and can be used for weaving high-density filter screens, printing screen, etc. [0003] Monofilaments are usually produced from chemical fibers using single hole spinnerets. However, with the continuous advancement of technology, there are more and more channels to obtain monofilament, which is no longer limited to chemical fiber...

AI Technical Summary

Problems solved by technology

However, due to the relatively thick split fiber mother silk, the denier per filament is generally 30D to 80D, and the split fiber mother silk produced by the existing split fiber mother silk spinning and pulling combination mechanism has quality problems such as uneven tow and low strength of the finished yarn. Limits the further popularization and application of one-step split fiber mother filament (single filament) spinning process
