The elastic knitted fabrics obtained in example 1 and comparative example 1~3 were subjected to performance tests, and the test results are shown in table one below.
Table one:
as can be seen from the table I, the difference between the comparative example 1 and the example 1 is that the conventional polyester fiber is adopted as the raw material, the antibacterial agent is added in the dyeing process and mixed with the fiber, and as can be seen from the table I, the escherichia coli inhibition rate is greatly reduced after 50 times of water washing, and the main reasons are that the antibacterial agent is gradually consumed along with daily washing, and the antibacterial force is gradually reduced, so that the technical problem is caused.
The difference between the comparative example 2 and the example 1 is that in the raw material ratio, the T400 fiber with the weight ratio of 30% is increased to 40%, as can be seen from table one, the shrinkage elongation and the elastic recovery rate of the fiber have obvious promotion tendency, because the T400 fiber has unique high elasticity, but because the ratio is too high, when the shrinkage elongation is more than 160%, under the condition of external tension, the nano zinc polyester fiber as the fiber skeleton structure can not well limit the stretching degree of the T400 fiber, the fiber structure is damaged, and the drawing defect of the fabric can be caused in the subsequent circular weaving process.
The difference between the comparative example 3 and the example 1 is that the conventional fiber texturing process is adopted, and as can be seen from table one, the elastic elongation and the elastic recovery rate of the fabric are greatly reduced, and the main reason for the phenomenon is that the two fibers are not uniformly mixed due to blending of the nano zinc polyester fibers and the T400 fibers by adopting the conventional process, the problem that the two fibers are not uniformly mixed due to the fact that the fiber shrinkage is further aggravated due to the fact that the heating temperature is too high is caused, and meanwhile, the internal tissue structure of the T400 fibers is also damaged, so that the final fiber compression elongation and the elastic recovery rate are greatly reduced.
Finally, it is noted that the above-mentioned preferred embodiments illustrate rather than limit the invention, and that, although the invention has been described in detail with reference to the above-mentioned preferred embodiments, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the invention as defined by the appended claims.
