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.
