Preparation and application of tea extract oil composite modified additive

Abstract

The invention belongs to the technical field of functional fiber, relates to preparation and application of a tea extract oil composite modified additive, and aims to preparation of functional adhesive fiber. The preparation comprises the following steps: preparing a solid adsorbent containing a tea extract; preparing tea oil micro-capsule slurry; uniformly mixing the solid adsorbent and the tea oil micro-capsule slurry, and stirring so as to obtain a composite modified additive; preparing adhesive fiber with a tea fragrance antibacterial deodorization function, wherein preparation of the adhesive fiber comprises the following steps: preparing a commixed spinning liquid, and spinning; the prepared adhesive fiber with the tea fragrance antibacterial deodorization function comprises 1.0-11.0wt% of an adsorbent of a porous structure, 2.0-5.0wt% of a tea extract and 1.0-11.0wt% of a tea oil micro-capsule. The tea extract oil composite modified additive is stable in property, can be uniformly fused with an adhesive stock solution, and has long-lasting tea fragrance and an antibacterial deodorization function, and effective components in fiber are slightly lost in the spinning process and later treatment process.

Description

technical field [0001] The invention belongs to the technical field of functional fibers, and in particular relates to a compound modification additive of tea extract and tea oil, which is used for the preparation of functional viscose fibers. Background technique [0002] With the continuous improvement of living standards, people not only have an increasingly strong pursuit of green consumption and environmentally friendly products, but also have higher and higher requirements for the functionality and comfort of textiles. Because viscose fiber products have the characteristics of moisture absorption, good air permeability and comfortable wearing, they have been widely used. However, most viscose fibers in my country are conventional varieties, and there are few types of functional fibers and differentiated fibers, and there is still a large gap in quality compared with foreign countries. Therefore, new varieties of viscose fibers with high performance and differentiation ...

The bamboo charcoal used in this patent is black, so the color of the fiber is limited, which hinders the expansion of its application field

At the same time, the tea polyphenols extracted are water-soluble. Although the adsorption of bamboo charcoal can reduce the loss of tea polyphenols, the loss is also relatively large.

[0009] Chinese patent 201310117692.3 discloses a preparation method of tea tree oil microcapsules antibacterial health-care fiber, comprising the following steps: preparing tea tree oil emulsified dispersion: fully emulsifying tea tree oil in an emulsifier, and obtaining a tea tree oil emulsified dispersion after emulsification; preparing Mixed dispersion system of core material and wall material: fully disperse the emulsified tea tree oil into the dispersion formed by the wall material with a dispersant to prepare the mixed dispersion system of core material and wall material; the mixing of core material and wall material The dispersion undergoes complex coacervation reaction; preparation of tea tree oil microcapsule dispersion: in the mixed dispersion system of the core material and wall material in the previous step, the curing agent, the dispersion after complex coagulation and cross-linking curing reaction, is the tea tree oil microcapsule Emulsion; preparation of tea tree oil microcapsules antibacterial health care fiber finishing agent: adding reaction amount catalyst, crosslinking agent and penetrating agent in the obtained tea tree oil microcapsule emulsion to prepare tea tree oil microcapsule antibacterial health care fiber finishing agent; preparation of tea tree oil microcapsules Antibacterial health-care fiber fabric of oil microcapsules: the tea tree oil microcapsule antibacterial health-care fiber finishing agent is applied to the pre-treatment or post-treatment of fiber fabrics to obtain antibacterial health-care fiber fabrics loaded with tea tree oil microcapsules; microcapsules still exist easily Loss during spinning and subsequent processing
