Embodiment 1

[0025] The raw material of embodiment 1 apocynum extract

[0026] The apocynum extract raw material that the present invention selects is the apocynum extract powder, and the requirement of raw material is as follows:

[0027] Loss on drying ≦5.0%, heavy metal content ≦10ppm, total flavonoid glycosides content ≥3.5%, mesh number 80-120.

Embodiment 2

[0029] A preparation method of viscose fiber containing apocynum extract, comprising the following steps:

[0030] (1) Preparation of antibacterial agent solution

[0031] Add Apocynum extract powder to water at a temperature of 25±1°C in an amount of 120g / 1000ml of water, stir well until the powder is completely dissolved to form an antibacterial agent solution, and obtain liquid A.

[0032] (2) Add dispersant

[0033] Add the dispersant to the above liquid A and stir to obtain liquid B.

[0034] (3) Add sodium carboxymethyl cellulose

[0035] Add carboxymethyl cellulose sodium powder into the above liquid B while stirring in a temperature range of 50-60°C in a certain mass ratio to obtain liquid C.

[0036] (4) Blending with spinning dope

[0037] The above liquid C was added to the spinning stock solution at a mass ratio of 15% of the spinning stock solution, stirred and dispersed, and then left to stand for vacuum defoaming to obtain liquid D.

Abstract

The invention provides a preparation method of viscose fiber containing an apocynum venetum extract. The preparation method comprises steps as follows: an antibacterial agent solution is prepared, a dispersing agent is added, sodium carboxymethylcellulose is added, the mixture is blended with a spinning solution, and spinning and aftertreatment are performed. The viscose fiber has a good dyeing effect and high antibacterial ability; the inhibition ratio of staphylococcus aureus is up to 99.0%-99.3%; the inhibition ratio of escherichia coli is up to 98.9%-99.4%, and the inhibition ratio of candida albicans is up to 93.0%-95.7%. The prepared viscose fiber has high strength and high wet modulus; the dry strength reaches 6.1-6.4 cN/dtex, the wet strength reaches 4.9-5.0 cN/dtex, the elongation at break reaches 23%-25%, and the wet modulus reaches 0.64-0.67 cN/dtex.

Description

technical field [0001] The invention belongs to the technical field of man-made fibers, and relates to a method for preparing fibers, in particular to a method for preparing viscose fibers containing apocynum extract. Background technique [0002] Existing conventional viscose fiber is regenerated cellulose fiber, and its products have the characteristics of good moisture absorption and air permeability, and comfortable wearing. With the improvement of people's living standards and the change of life concepts, people pay more and more attention to the health care function of textiles, and hope that the existing viscose fiber textiles can be improved in terms of antibacterial properties; Insufficient antibacterial ability, low strength, poor dyeing effect, low wet modulus and other defects. [0003] The antibacterial agents used in antibacterial fiber products are basically divided into three categories, namely natural antibacterial agents, organic antibacterial agents and i...
