Embodiment 1

[0017] The preparation process of the simulated silk is as follows: the specific process is: heating, melting and metering the slices in the silo, performing spinning and melting extrusion in the screw extruder, removing impurities through the spinning assembly, spraying The extruded silk is cooled and formed by the side blowing system, and then the formed silk is oiled, and then the post-processing process is carried out, and finally the silk is wound and formed.

[0018] Among them, the silo is specifically: storing and protecting the slices required for production; the slices are specifically PET polyester slices or polycaprolactam slices, and are dried.

[0019] The function of the screw extruder is to heat, melt and measure the chips through the feeding section, compression section, and metering section to generate a predetermined pressure and extrude from the head of the screw; the temperature of each area of ​​the screw: 250 / 260 / 260 / 260 / 262; pressure control is 120kgf / ...

Abstract

The invention relates to the manufacturing technology of a synthetic fiber and especially relates to the manufacturing technology of a simulated silk. The manufacturing technology of the simulated silk comprises the following processes of heating, melting and metering the slices of a stock bin; carrying out spinning melt extrusion in a screw extruder; through a spinning component, removing impurities and jetting filaments, wherein the jetted filaments are cooled and shaped through a side blowing system; then, oiling the shaped filaments via an oil nozzle; and finally, winding the filaments toform a shape. The simulated silk meets the requirements of the same feeling and the shrinking percentage of a silk, simultaneously possesses higher tensile resistance and breaking strength and is noteasy to fracture.

Description

technical field [0001] The invention relates to a production and preparation process of artificial synthetic fibers, in particular to a preparation process of simulated silk. Background technique [0002] Silk is the lightest, softest and thinnest natural fiber in nature. It can easily return to its original shape after the external force is removed. The structure of natural silk is very similar to that of human skin. Nowadays, there is a wave of silk beauty in the beauty industry. Silk cosmetics developed from silk have become the first choice for skin care of countless beauty-loving women. However, the area and output of sericulture are limited after all, so that the price of silk is generally high, and the stretch resistance of silk is relatively poor. Therefore adopting chemical fiber superfine fiber to imitate real silk has huge consumption market. There are still differences in luster, feel and performance in the existing chemical fiber silk spinning silk. Contents...
