Description
Technical Field
The invention relates to the technical field of textile material preparation, in particular to a preparation method of cuprammonium complex viscose.
Background
The cuprammonium fiber is prepared by dissolving natural cellulose such as cotton linter in cuprammonium solution to prepare spinning solution, and finally decomposing and producing cellulose in coagulating bath. Compared with the traditional cellulose fiber, the copper ammonia fiber has the advantages of high strength, soft and fine luster, good hygroscopicity, good air permeability, good drapability of fabrics processed by the copper ammonia fiber, good dyeing property, comfortable wearing, and very wide product development prospect, but the expensive preparation price severely limits the application market of the copper ammonia fiber.
Based on the preparation method of the cuprammonium fibers, the application tries to control the concentration of the cuprammonium solution to be insufficient for dissolving the viscose fibers, so that the effect of adsorbing copper (II) by the viscose fibers is achieved.

In order to achieve the above purpose, the present invention adopts the following technical scheme:
the preparation method of the cuprammonia complex viscose fiber comprises the following specific steps:
step 1: pretreating viscose fiber to remove greasy dirt and impurities on the surface of the viscose fiber;
step 2: weighing CuSO with certain mass 4 Respectively dissolving NaOH and deionized water, and mixing the two materials in a beaker to generate Cu (OH) 2 Precipitation, the color presents blue; vacuum filtering, cleaning the solution, and washing the precipitate with deionized water for several times to obtain Cu (OH) 2 Precipitating; then Cu (OH) 2 Completely dissolving the precipitate with ammonia water to obtain a copper ammonia solution with a color of Tibetan blue;
step 3: using the cuprammonium solution obtained in the step 2 as an antibacterial treatment solution, performing antibacterial finishing on the pretreated viscose fiber at a certain temperature, cooling, repeatedly flushing with deionized water to neutrality, and drying at 60 ℃;
step 4: and (3) performing antibacterial performance test on the complex copper ammonia fiber obtained in the step (3).
Preferably, in step 1, the viscose is soaked in warm water containing JFC at concentration of 1%, temperature of 20-40deg.C and cycle time of 10-30min.
Preferably, in step 2, cuSO 4 The mass ratio of NaOH to the catalyst is 1:2-1:4, cu (OH) 2 The mass ratio of the ammonia water is 1:2-1:3, and the PH of the finally obtained cuprammonium solution is 12.
Preferably, in the step 3, the bath ratio is 1:50-1:100, the reaction temperature is 20-40 ℃, and the reaction time is 60-180min.
By adopting the technical scheme: viscose as cellulose fibres, contains a large number of hydroxyl groups, the oxygen atoms on which can provide lone pair electrons in the coordination chemistry; while Cu (ii) as a metal ion can provide an empty orbital to complex with the fiber. In addition, when cellulose fibers are contacted with water, an aqueous solution or a non-aqueous solution, the surface thereof obtains electric charges, and since the fibers themselves contain a glycosidic bond, a polar hydroxyl group or the like, the surface thereof is always negatively charged. The mechanism is that the electric double layer theory of the adsorption layer and the diffusion layer generates a potential difference due to the relative motion of the adsorption layer and the diffusion layer, and the viscose fiber can adsorb certain metal ions under a proper pH value.
Compared with the prior art, the invention has the following beneficial effects:
1. the invention realizes the functional modification of the viscose fiber at normal temperature and normal pressure, the method is simple, the used raw materials and reagents are cheap and easy to obtain, the production cost is reduced, and the wear resistance, the tensile strength and the acid and alkali resistance of the cuprammonium cellulose prepared by the invention are obviously improved.
2. The preparation method disclosed by the invention is simple to operate, the spinning and post-treatment are not needed, the cost is low, and the prepared antibacterial viscose fiber is soft in hand feeling, good in antibacterial effect, not easy to break and long in service life.
3. The invention has the advantages of small pollution caused by preparation, low preparation cost and meeting the requirements of ecological textiles.
