[0003] A preparation method of nylon yarn is disclosed in the Chinese patent database, the patent application number: CN201810067425.2, application date: 2018-1-23, publication number: CN108193305A, publication date: 2018-06-22; the nylon yarn It is prepared by mixing organic copper complexes with germanium powder slurry and modified anion far-infrared powder color masterbatch and nylon 6 (PA6) slices, and then melt spinning, cooling, and winding. It has far-infrared, anion functional, and no dyeing process is required, but the disadvantage of the product is that the compatibility between germanium powder slurry and PA6 material is poor, making it difficult to manufacture, and the product has a single function and does not have an aromatic function
In addition, a production method of aromatic nylon fibers is also disclosed in the Chinese patent database. The application number of this patent is: CN 201110450221.5, the application date: 2011-12-29, the publication number: CN103184573A, the publication date: 2013-07-3 The nylon fiber preparation method is as follows: mix the essence clathrate and nylon chips, and prepare masterbatches by granulating through a granulator, then mix the masterbatches with nylon chips, and obtain aroma function through screw melt spinning. Nylon fiber: the production process of this invention is simple, the performance of the produced nylon fiber is good, it is easy to post-process, it is washable, and the fragrance releases for a long time, but the advantage is that the product does not have a single function and does not have the function of negative ions

Abstract

The invention discloses a preparation method of aromatic anion nylon filaments in the field of chemical fiber production. The method comprises the following steps of drying and mixing aromatic anion nylon master batch and nylon 6 slice raw materials to obtain a mixture; then, extruding and melting the mixture through a screw to obtain a melt, and then preparing the nylon filaments with an aromaticanion function through the procedures of filtering, metering spinning, circular blowing for cooling and shaping, oiling and winding. According to the nylon filaments, the aromatic anion nylon masterbatch and nylon 6 slices are adopted for melt spinning, the preparation method is reasonable, the operability is high, and industrial implementation is easy. The nylon filaments can continuously release anions and a fragrant and fresh smell and has not only the functions of purifying air and removing indoor peculiar smell but also a good healthcare effect. The aromatic anion nylon filaments obtained by means of the method have the advantages of high spinnability, lasting functions and long service life, and can be widely applied to the fields of clothing, home textiles, automobile interior decoration and the like.
