Abstract

The invention discloses a production process of modified chinlon yarn. The production process includes the following steps: 1, mixing 7-8 parts of polyamide slices, 2-4 parts of graphene, 3-6 parts of far infrared ceramic powder, 6-9 parts of an antioxidant, 5-10 parts of a catalyst and 8-12 parts of a dispersing agent, feeding the above materials into a stock bin, mixing and melting to prepare functional master batch; 2, feeding the functional master batch and 70-80 parts of dried chinlon slices into a double-screw extruder to be extruded, then carrying out blended spinning at the temperature of 260-265 DEG C, and finally, carrying out oiling, winding and balanced stretching to obtain chinlon yarn; 3, soaking the chinlon yarn in the step 2 into a graphene solution through a compression roller, guaranteeing that the chinlon yarn makes full contact with graphene, after soaking is completed, feeding the chinlon yarn into a drying device for drying, and finally obtaining the novel modified chinlon yarn. The preparation method is simple, and the prepared modified chinlon yarn is good in use effect, good in antistatic performance, capable of keeping warm, convenient to use, safe and reliable.
