Abstract

The invention provides a preparation process of a tea polyphenol, naringin or emodin modified PET master batch. The preparation process comprises the following steps: dissolving a plant extract, carrying out ultrasonic-assisted dispersion, preparing nano microspheres, preparing a functional modifier, and preparing functional master batch, wherein the plant extract is tea polyphenol, naringin or emodin, in the ultrasonic-assisted dispersion, the ultrasonic frequency is 33-38 KHZ, the ultrasonic dispersion time is 28-32 min, and the temperature is 30-34 DEG C, and in the step of preparing the nano microspheres, the adopted raw materials are one or more of montmorillonite, zeolite powder, aerogel, porous nano TiO2 and porous nano SiO2. The prepared tea polyphenol, naringin or emodin modifiedPET master batch is good in antibacterial effect and washable effect and has a natural cool feeling.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to a PET masterbatch modified with tea polyphenols, naringin or emodin and a preparation process thereof. Background technique [0002] Polyester, or PET, is an important variety of synthetic fibers and the trade name of polyester fibers in my country. It is a fiber-forming high polymer prepared from purified terephthalic acid (PTA) or dimethyl terephthalate (DMT) and ethylene glycol (EG) through esterification or transesterification and polycondensation reactions— Polyethylene terephthalate (PET), a fiber made by spinning and post-processing. As an important raw material for the textile industry, polyester fiber has alleviated the shortage of natural fibers to a large extent. It has become the largest synthetic fiber variety among chemical fibers and is widely used in clothing, decoration, home textiles, industrial textiles, national defense, industrial va...
