Comparative example 2: this comparative example is different from example 1 in that no wormwood fiber was added in step S1.
Fourthly, performance test
1) The tencel fibers prepared according to preparation examples 1 to 6 were subjected to a performance test according to the following method, and the test results are shown in table 1.
Elongation at break: according to GB/T24218.18-2014 & lt & gt determination of breaking strength and breaking elongation (sample grabbing method), the breaking elongation of the tencel fiber is tested.
Moisture regain: and testing the moisture regain of the tencel fiber according to GB/T6529-2008 standard atmosphere for humidifying and testing textiles.
TABLE 1
As can be seen from the data in Table 1, the tencel fiber prepared in the preparation example of the invention has higher moisture regain and better hygroscopicity, and the elongation at break of the tencel fiber is closely related to the moisture regain of the tencel fiber; the tencel fiber is spun by an organic solvent under the physical action, the whole manufacturing process is non-toxic and pollution-free, the solvent used in the spinning process can be continuously recycled, and the recovery rate of ammonium oxide is as high as 99 percent; and the tencel fiber has the advantages of softness, drapability, unique touch, air permeability, moisture permeability, mite prevention and static resistance, and the product of the tencel fiber can be biochemically degraded after being used and discarded, so that the burden of waste treatment is reduced.
As can be seen from table 1, in the process for producing tencel fiber, the water content of the aqueous solution of N-methylmorpholine oxide is in the range of 13.3% to 17%, wherein the dissolving capacity of the aqueous solution of N-methylmorpholine oxide for cellulose is improved with the increase of the water content of the aqueous solution of N-methylmorpholine oxide, and when reaching a high point, the fiber begins to fall back, and in preparation examples 1 to 3, the temperature is the same when the pulp and the aqueous solution of N-methylmorpholine oxide are mixed and dissolved; in preparation example 2, when the water content of the aqueous solution of N-methylmorpholine oxide was 15%, the tencel fiber produced had good effects in terms of elongation at break and moisture regain.
As can be seen from Table 1, the dissolving effect of the tencel fiber is firstly increased to the highest point within the temperature range of 85-120 ℃ when the pulp and the aqueous solution of the N-methylmorpholine oxide are mixed and dissolved; beginning to fall back, in preparation examples 2 and 4-5, when the water content of the aqueous solution of the N-methylmorpholine oxide is 15%; in preparation example 4, when the temperature for mixing and dissolving the pulp and the aqueous solution of N-methylmorpholine oxide is 100 ℃, the manufactured tencel fiber has good effect on the detected elongation at break and moisture regain.
As can be seen from table 1, preparation example 6 did not add an antioxidant in addition to preparation example 4; when cellulose pulp is dissolved in an aqueous solution of N-methylmorpholine oxide, the polymerization degree of cellulose is reduced, the cellulose is easy to degrade, and when the cellulose is mixed with a solvent and heated, the aqueous solution of N-methylmorpholine oxide is decomposed to release amine compounds, and the viscosity of the solution is reduced and the color is darkened along with the degradation; therefore, the addition of the antioxidant can effectively reduce the oxidative degradation of the cellulose and the decomposition of the aqueous solution of the N-methylmorpholine oxide.
Finally, the conclusion shows that the tencel fiber prepared in the preparation example 4 has larger breaking elongation and higher moisture regain.
2) The environment-friendly beds produced by the methods of examples 1 to 5 and comparative examples 1 to 2 were subjected to performance tests as follows, and the test results are shown in table 2.
Shrinkage rate: and (3) testing the shrinkage of the environment-friendly bedquilt according to JJF (textile) 052-2012 calibration standards for fabric shrinkage testing machines.
Electrostatic property: according to GB/T12703.3-2009 part 3 of evaluation of electrostatic properties of textiles: charge amount, the charge carried by the environment-friendly bed after being rubbed with standard cloth is tested.
TABLE 2
The data in table 2 show that, when the fabric is rubbed, the amount of accumulated charges depends on the moisture content and the conductivity of the fabric, moisture can capture electrons to reduce the generation of static electricity, the natural moisture content of the tencel fiber reaches 13%, and the moisture regain is high, so that the electrostatic charges are difficult to accumulate under the condition of strong moisture conductivity of the tencel fiber, and the fabric made of the tencel fiber has good antistatic capability; the moisture regain of the same bamboo fiber is higher, and the higher the moisture regain of the tencel fiber is, the better the antistatic property of the environment-friendly bed quilt is under the condition of the tencel fiber prepared by different preparation examples.
Similarly, because the cohesive force between the tencel fiber and the cellulose fiber is large, the shrinkage rate is low, and similarly, the comparison between examples 1-5 and the preparation example 1 shows that the moisture regain of the tencel fiber prepared by different temperatures and the water content of the aqueous solution of N-methylmorpholine oxide can influence the static electricity of the environment-friendly bedspreads prepared by the examples and the comparative examples, but the influence on the shrinkage rate is not large; however, tencel fibers prepared without adding an antioxidant have a large influence on the shrinkage and the static property of the final environment-friendly bedspread.
Similarly, in comparative example 2, no wormwood fiber was added, and both the electrostatic property and the shrinkage rate were not significantly affected from the measurement data.
The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape and principle of the invention are covered by the protection scope of the invention.
