Abstract

The invention provides a preparation method of an antibacterial and heat-accumulating radix isatidis modified PE master batch. The preparation method comprises the following steps: dissolving a radixisatidis extract, modifying the radix isatidis extract, preparing a loading agent, loading the extract, preparing a functional master batch and carrying out post-treatment, wherein the post-treatmentcomprises the steps of preparing a post-treatment solution, mixing and heating the components, and cleaning and drying the mixture; the preparation of the post-treatment liquid comprises the followingraw material components in parts by weight: 10 to 13 parts of grape polyphenol, 6 to 8 parts of sorbitol, 15 to 18 parts of sodium alginate, 7 to 7.8 parts of gallic acid, 2 to 3 parts of sodium stearate, 9 to 11 parts of glycerol, 4 to 5 parts of vitamin E, 3 to 3.5 parts of mannitol and 30 to 35 parts of deionized water. According to the preparation method, the antibacterial stability, the washing resistance and the heat storage performance of the isatis root modified PE master batch are improved.

Description

technical field [0001] The invention belongs to the technical field of fiber manufacturing, and in particular relates to an antibacterial heat-storing Radix isatidis modified PE masterbatch and a preparation method thereof. Background technique [0002] In order to improve the heat-retaining effect of woven fabrics, the conventional way is to add layers and thicken the woven fabrics, which causes the fabrics to be not only heavy and poor in air permeability, but also greatly affects the texture of the fabrics and its wearing comfort. This year, technicians continue to study the heat storage performance of raw materials from the source. Especially for PE masterbatch, a lot of modification research has been done in this field, but the related technology is not mature. [0003] At the same time, the antibacterial modification technology of PE masterbatch is also an important aspect of research by technicians in recent years. The traditional antibacterial means is to add inorg...
