Embodiment 1

[0027] Preparation of 1.33 dtex×38mm viscose fiber with plant protein, anti-virus and anti-bacterial functions:

[0028] 1. Preparation of modified functional agent

[0029] 1) Preparation of modified zeolite

[0030] First, soak the clinoptilolite in deionized water and dry it, then put the washed and dried zeolite into a saturated solution of sodium hydroxide at 60°C for 4 hours, and then take out the modified zeolite and wash it with deionized water until neutral ,drying.

[0031] 2) Extraction and preparation of functional components of lotus pod and lotus leaf

[0032] First, the lotus pods and lotus leaves were dried and ground into powders of 100-120 mesh, and 80% ethanol was added to the powders, extracted for 48 hours, concentrated to make aqueous suspensions. Then, the above water suspension of lotus pod and lotus leaf is purified, and petroleum ether, ethyl acetate and n-butanol are used for extraction and purification in sequence. Finally, the obtained ethyl ac...

Abstract

The invention discloses a preparation method of multifunctional viscose fiber containing vegetable protein, and belongs to the technical field of preparation of functional regenerated cellulose fiber.The preparation method comprises the following steps that firstly, in-situ loading is conducted on a lotus seed pot extract and a lotus leaf extract by adopting modified zeolite, then zeolite after adsorbing the extracts is dried and ground to prepare a modified functional agent, then the modifying agent is mixed with a vegetable protein solution, and finally a mixture is blended with a viscose stock solution to obtain the multifunctional viscose fiber. The viscose fiber which contains the vegetable protein and has antiviral and antibacterial functions is prepared by a wet spinning process.

Description

technical field [0001] The invention belongs to the technical field of preparation of functional regenerated cellulose fibers, and in particular relates to a preparation method of multifunctional viscose fibers containing vegetable protein. Background technique [0002] Viscose fiber and its products have the characteristics of moisture absorption, breathability, comfortable wearing and wide application. The functional fibers developed with viscose as the base material can increase the added value of products on the one hand, and meet the diversified needs of consumers on the other hand. Compared with the previous method of preparing functional fibers by coating or adhering with chemical or synthetic functional agents, in recent years, functional fibers made by adding natural plants as functional agents to fibers have become more and more popular among consumers. [0003] And lotus, Nymphaeaceae lotus is a perennial aquatic herb, the whole body is a treasure. The lotus can...
