Embodiment 1

[0026] Embodiment 1 Grass coral extract raw material

[0027] The grass coral extract raw material that the present invention selects is grass coral extract powder, and the requirement of raw material is as follows:

[0028] Loss on drying ≦5.0%, heavy metal content ≦20ppm, isoferidine content ≥0.15mg / g, astilbin content ≥50mg / g, mesh number 80-120.

Embodiment 2

[0030] A preparation method of viscose fiber containing a grass coral extract, comprising the following steps:

[0031] (1) Preparation of antibacterial agent solution

[0032] Add the powdered coral coral extract to water at a temperature of 25±1°C in an amount of 100g / 1000ml of water, stir well until the powder is completely dissolved to form an antibacterial agent solution, and obtain liquid A.

[0033] (2) Add dispersant

[0034] Add the dispersant to the above liquid A and stir to obtain liquid B.

[0035] (3) Add carboxymethyl cellulose sodium

[0036] 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.

[0037] (4) Blending with spinning dope

[0038] 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.

[0039] (...

Embodiment 3

[0043] Example 3 Dispersant Type Single Factor Analysis Experiment

[0044]

[0045] 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 Viscose fibers containing Coralia pratense extract were prepared.

Abstract

The invention provides a preparation method of viscose containing sarcandra glabra extract. The preparation method comprises the following steps: preparing antibacterial agent solution, adding a dispersing agent, adding and mixing sodium carboxymethyl cellulose and spinning solution, spinning and performing aftertreatment. The viscose is excellent in dying effect, and high in antibacterial ability, strength and wet modulus, and has the inhibition ratio of 99.1%-99.4% to staphylococcus aureus, the inhibition ratio of 98.7%-99.2% to escherichia coli and the inhibition ratio of 93.4%-95.6% to candida albicans, and has the dry-state strength of 6.2-6.3 cN / dtex, the wet-state strength of 4.7-4.9 cN / dtex, the breakage elongation at break of 23-25%, and the wet modulus of 0.63-0.65 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 coral extracts. 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, resulting in unstable fabric size and other defects. [0003] The antibacterial agents used in antibacterial fiber products are basically divided into three categories, namely natural antibacterial agents, o...
