Embodiment 1

[0051] Embodiment 1 A kind of health-care regenerated cellulose fiber containing meteorites and a preparation method thereof, comprising the following steps:

[0052] Step 1, preparation of meteorite dispersion solution:

[0053] Including the following process:

[0054] (1) Add dispersant a

[0055] Add 1.5% dispersant a to 1000g deionized water and keep the temperature at 22°C;

[0056]The dispersant a is composed of 2 parts of polypropylene sodium salt, 3 parts of sodium polymetaphosphate and 1 part of sodium pyrophosphate.

[0057] (2) Add Bianstone powder

[0058] Add 50g of meteorite powder, the feeding speed is 10g / min, and keep stirring, the stirring speed is 45r / min;

[0059] The meteorite powder has a particle size of 4 μm.

[0060] (3) Add thickener

[0061] Add 10g of thickener to the solution obtained in (2), increase the temperature to 42°C at a rate of 1°C per minute, increase the stirring speed by 5r per minute to 120r / min, and keep for 10 minutes;

[00...

Embodiment 2

[0084] Example 2 The single factor analysis experiment of the largest diameter of meteorite particles in the meteorite dispersion solution

[0085] Using the fiber preparation described in Example 1, only change step 1, the preparation of the meteorite dispersion solution, (5) the maximum diameter of the meteorite particles during the ultrafine grinding process, and perform a single factor analysis experiment, see Table 2.

[0086] Table 2 The single factor analysis experiment of the maximum diameter of meteorite particles in the meteorite dispersion solution

[0087]

[0088] From the above single factor analysis experiments, it can be seen that Example 5 is a preferred embodiment, that is, in the meteorite dispersion solution, the maximum diameter of the meteorite particles is preferably 0.3 μm.

Embodiment 8

[0089] Example 8 Single factor analysis experiment of the mass ratio of meteorite dispersion solution and regenerated cellulose spinning stock solution

[0090] Using the fiber preparation described in Example 1, only changing the mass ratio of the meteorite dispersion solution to the regenerated cellulose spinning stock solution in step 3, the preparation of the blended spinning solution, and performing a single factor analysis experiment, see Table 3 for details.

[0091] Table 3 Single factor analysis experiment of the mass ratio of meteorite dispersion solution and regenerated cellulose spinning stock solution

[0092]

[0093] Through the above single factor analysis experiment, it can be seen that Example 5 is a preferred example, and the mass ratio of the meteorite dispersion solution to the regenerated cellulose spinning stock solution is preferably 7:100.

Abstract

The invention provides a stone needle-containing healthcare regenerated cellulose fiber. The fiber has dry breaking strength more than or equal to 2.4cN / dtex, wet breaking strength more than or equal to 1.5cN / dtex and dry breaking stretching rate more than or equal to 19%. The invention also provides a preparation method for the fiber. The method comprises the step of preparing a co-blending spinning solution, wherein the mass ratio of a stone needle disperse solution to a regenerated cellulose spinning solution is 2:1000 to 1:10 in the step of preparing the co-blending spinning solution. The antibacterial rate of the acquired fiber according to the invention to staphylococcus aureus is more than or equal to 90.0%, the antibacterial rate to escherichia coli is more than or equal to 91.0%, and the antibacterial rate to candida albicans is more than or equal to 85.0%. The acquired fiber according to the invention has dry breaking strength more than or equal to 2.4cN / dtex, wet breaking strength more than or equal to 1.5cN / dtex and dry breaking stretching rate more than or equal to 19%. The stone needle-containing healthcare regenerated cellulose fiber prepared according to the invention contains 6-8% of stone needle.

Description

technical field [0001] The invention relates to a functional regenerated cellulose fiber and a preparation method thereof, in particular to a health-care regenerated cellulose fiber containing meteorites and a preparation method thereof, belonging to the technical field of regenerated cellulose fiber production. Background technique [0002] Regenerated cellulose fibers were industrially produced as early as the beginning of the 20th century. Because of its performance similar to that of cotton, the moisture regain meets the physiological needs of human skin. At the same time, it has the advantages of breathability, smoothness, antistatic, and easy dyeing. It has a wide range of applications, such as medical and health care, home textiles, and clothing. With the continuous development of science and technology, using the characteristics of regenerated cellulose fibers, various new functional fibers based on regenerated cellulose fibers have been successfully developed, furth...
