Problems solved by technology

[0004] At present, the antibacterial viscose fibers prepared by adding natural antibacterial agents all have natural antibacterial agents that are easy to lose during spinning. The prepared fibers have poor antibacterial properties, low strength, and low wet modulus. They are easily deformed after washing, and the antibacterial properties are greatly weakened. Poor fabric shape retention

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 carboxymethyl cellulose sodium

[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.

[0038] (5) spinning

...

Embodiment 3

[0042] Embodiment 3 dispersant type single factor analysis experiment

[0043]

[0044] Adopt the dispersant described in embodiment 4-8, the mass ratio that the addition amount of dispersant accounts for A liquid is 1.5%, the mass ratio of sodium carboxymethyl cellulose and B liquid is 1:50, according to implementing 2 Preparation method The viscose fiber containing Apocynum extract was prepared.

Abstract

The invention provides a preparation method of antibacterial viscose fiber containing apocynum extract, comprising the following steps: preparing an antibacterial agent solution, adding a dispersant, adding sodium carboxymethyl cellulose, blending with spinning stock solution, and spinning , post-treatment; the viscose fiber prepared by the present invention has good dyeing effect and strong antibacterial ability, and the inhibition rate to Staphylococcus aureus reaches 99.0%-99.3%, and the inhibition rate to Escherichia coli reaches 98.9-99.4%. The inhibition rate of bacteria reaches 93.0-95.7%; the viscose fiber prepared by the present invention has high strength and high wet modulus: the dry strength reaches 6.1-6.4cN / dtex, the wet strength reaches 4.9-5.0cN / dtex, and the elongation at break The rate reaches 23-25%, and the wet modulus reaches 0.64-0.67cN / 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...
