Abstract

The invention provides a preparation process of an anti-aging tea polyphenol, naringin or emodin modified chinlon master batch. The preparation process comprises a loading agent preparation step, andthe preparation of a loading agent comprises the steps of raw material pretreatment, blending, heat treatment, elution and drying. In the blending step, preparation raw materials of the loading agentare added into a stirring kettle and stirred for 8-15 min at the rotating speed of 1200-1500 rpm to obtain a mixed material A, the mixed material A is mixed with far infrared nano-powder to obtain a mixed material B, and the mixed material B is subjected to ultrasonic treatment for 28-32min at the temperature of 28-30 DEG C and at the ultrasonic frequency of 33-38 KHZ to obtain blended powder. Theheat treatment comprises the steps of mixing the blended powder with a treatment liquid, heating the mixture to 99-100 DEG C at a rate of 5-6 DEG C / min, and carrying out heat preservation and heat treatment for 30-40 minutes. The modified chinlon master batch prepared by the method is good in antibacterial property and remarkable in ageing resistance.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to an anti-aging tea polyphenol, naringin or emodin modified nylon masterbatch and a preparation process thereof. Background technique [0002] Modified nylon is a kind of engineering plastics, which is a granular product formed by changing the physical properties of nylon raw materials.
