Abstract

The invention provides fragrant chinlon masterbatch, a fragrant chinlon fiber and preparation methods thereof. The fragrant chinlon masterbatch is characterized by being prepared through the following steps: adsorbing an essence for heat-resistance rubber by a concavo-convex stick soil serving as a carrier; and mixing the concavo-convex stick soil and an additive and polyamide resin. The fragrant chinlon fiber prepared by performing spinning, oiling, stretching, elasticizing or cutting and other processes on a mixture of a chinlon slice and the fragrant chinlon masterbatch; the fineness of the fiber is 0.5 to 0.7 dtex; and the section of the fiber is circular, hollow or Y-shaped or is in another abnormal shape. The fragrant chinlon fiber can be a long fiber or a short fiber and can be suitable for POY (Polyester Pre-oriented Yarn) or FDY (Fully Drawn Yarn). Special equipment is not required; the process is simple; the technology is mature and stable; the concavo-convex stick soil is used as the essence carrier, so that an adsorption function and a slow-release function are realized; and the fragrant chinlon fiber has the characteristics of high essence utilization rate, durable fragrance, zero pollution, low production cost and high product additional value.

Description

technical field [0001] The invention relates to a chemical fiber manufacturing technology, in particular to a scented nylon fiber and a preparation method thereof. Background technique [0002] Nylon (chemical name: polyamide fiber) has the characteristics of high breaking strength, excellent wear resistance, light specific gravity, good elasticity and moisture absorption, excellent chemical stability, and is not easy to be moldy. Under normal conditions, it is not afraid of sweat, sea water, soap, etc. , lye, etc. Therefore, nylon is widely used, and can be used to make socks, underwear, clothing fabrics, non-woven fabrics, etc., and can also be used as tire cords, conveyor belts, cables, etc. Especially the demand for clothing and hosiery is growing rapidly, the output of domestic nylon is increasing rapidly, and the market competition is intensifying. However, there is a big gap between the production capacity and quality of various differentiated and functional products ...
