Problems solved by technology
Most chemical fibers with circular cross-sections have the disadvantages of smooth surface, poor adhesion, easy pilling, no water absorption, and small coverage
However, the special-shaped fibers produced by the prior art also have disadvantages such as easy generation of static electricity, poor softness and bulkiness, poor bending resilience, poor flexibility, and failure to achieve the effect of high imitation cotton.

Abstract
The invention discloses a preparation technology and preparation equipment for high-imitation cotton porous superfine profiled polyester fiber. The technological flow is as follows: polyester chips are dried, the dried polyester chips are placed in an extrusion device, polyhydric alcohol is added in an online manner to carry out blending modification, and then melt is obtained; the melt is filtered and enters a spinning manifold, the filtered melt is subjected to section superfine processing and section profiled processing, the melt is extruded by a profiled spinning plate, and then melt trickle is obtained; circular blowing cooling solidification forming is then carried out, and then filaments are obtained; and then the filaments are wound and formed sequentially through oiling by an oil nozzle, pretangle and heat setting. The preparation equipment comprises a drying device, an extrusion device, a filter device, the spinning manifold, a circular blowing cooling solidifying device and a winding forming device, which are connected in sequence, wherein the extrusion device is connected with an online adding device. The preparation technology and the preparation equipment have the characteristics of moisture absorption, breathability, anti-static electricity, pilling resistance, softness and bulkiness, soft gloss, moisture wicking and discharging, soft touch sense, better surface coverage and bending resilience, and also can realize a high-imitation cotton effect.
Description
technical field [0001] The invention relates to the field of polyester fibers, in particular to a preparation process and process equipment for high imitation cotton porous superfine special-shaped polyester fibers. Background technique [0002] Since polyester fiber was industrialized in 1953, it has high fiber strength, good elasticity, good heat resistance and chemical resistance, and good dimensional stability of the fabric. As the main textile raw material, it alleviates the shortage of natural fibers to a large extent. In recent years, with the continuous improvement of social consumption level, people's requirements for clothing have shown a trend of diversification. Due to the limitation of the performance of conventional polyester fibers, the market competition is becoming more and more fierce. Many polyester manufacturers have developed, developed and produced differentiated polyester fibers that are slightly more difficult but have higher added value. [0003] S...
