Production technology of chemical fiber color silk

Abstract

The invention discloses a production technology of chemical fiber color silk. The technology comprises the following steps of (1) slicing and dewatering, wherein polyester chips, color masterbatch, quicklime and molecular sieve desiccant are evenly mixed in a stirring barrel and stirred, moisture in the polyester chips is removed, the quicklime and the molecular sieve desiccant are filtered, and the dried polyester chips are obtained; (2) extrusion through a screw, wherein the dried polyester chips pass through a screw extruder and are heated in the screw extruder and fused, and high-temperature melt which is extruded from an outlet end of the screw extruder enters a spinning box; (3) cooling and spinning, wherein the high-temperature melt which enters the spinning box is extruded out fromfine holes of a spinneret plate, and an extruded melt fine flow is cooled into silk strips through lateral blowing wind; (4) bundling and oiling, wherein the cooled silk strips are bundled and oiledand prepared into the chemical fiber silk. The production technology has the advantages that the polyester chips are stirred, mixed and dewatered through the quicklime and the molecular sieve desiccant, the dewatering effect of the polyester chips is effectively improved, the firmness of the chemical fiber silk is improved, and the end breaking phenomenon of the chemical fiber silk is reduced.

Description

technical field [0001] The invention relates to a production process of chemical fiber color yarn. Background technique [0002] Chemical fiber yarn is a fiber made from natural or synthetic polymer materials and processed by chemical or physical methods. Most of the polymer material raw materials selected by existing chemical fiber yarns are polyester chips. In the process of making polyester chips, it is first necessary to remove water from the polyester chips, so as to avoid reducing the firmness of the manufactured chemical fibers and causing the phenomenon of chemical fiber breaking. [0003] The Chinese invention patent with the publication number CN102011211A discloses a method for preparing melt-spun chlorine-resistant high-resilience spandex fibers. During the manufacture of spandex fibers, dry polyester chips are obtained by heating at 70-120°C to remove water and dry. There are many raw materials of polyester chips in the manufacture of chemical fiber filaments,...

AI Technical Summary

Problems solved by technology

There are many raw materials of polyester chips in the manufacture of chemical fiber yarns, and the drying efficiency of polyester chips is low by heating and drying polyester chips by means of electric heating; and the effect of removing water from polyester chips piled up in the middle of the electric heating cylinder is not ideal, thereby reducing The firmness of chemical fiber is easy to break the end of chemical fiber

At the same time, electric heating to remove water and dry consumes energy, thereby increasing the manufacturing cost of chemical fiber filaments
