In hot seasons, people urgently need clothes with excellent moisture absorption and cooling performances, and the improvement of the moisture absorption and cooling functions of the fabric has important significance for research and development of textiles.
Natural fibers and chemical fibers are difficult to simultaneously meet the functions of moisture absorption and moisture conduction, although the natural fibers such as cotton have good moisture absorption property, sweat cannot be led out in time, and although the chemical fibers such as common polyester fibers have great advantages in water delivery property, the chemical fibers have poor moisture absorption property, so that a human body can feel stuffy and hot, and the comfort of clothing products is reduced. The moisture absorption and sweat releasing fiber usually has a special-shaped section with a large specific surface area and a surface which is fully distributed with grooves or pores, and can rapidly absorb and conduct moisture and sweat on the surface of skin by utilizing a capillary effect generated by micro-grooves, but the sweat is difficult to rapidly absorb and transfer, and only when the sweat contacts a hydrophilic part of a soaking surface or contacts a hydrophilic penetrating surface through pores and micro-pores of the soaking surface, the sweat can be rapidly transferred and discharged, so that the initial discomfort of the sweat is obvious.

Comparative example 1
Comparative example 1 differs from example 1 in that: comparative example 1 the modified polyester fiber yarn was replaced with a polyester fiber yarn which was not modified.
Evaluation and test of Effect
Liquid moisture management Performance (MMT)
The cotton fabric to be measured was cut into a size of 8cm × 8cm according to the GB/T21655.2-2009 standard, and the samples of examples 1 to 5 and comparative example 1 were measured using a liquid moisture management tester. The data are shown in Table 1.
Table 1 MMT test results for each group
Figure BDA0003506789110000131
It is known that the faster the wetting time, the greater the average water absorption rate and the greater the liquid water diffusion rate, the more hydrophilic is indicated. As can be seen from table 1, the hydrophilicity of the upper layer of the fabrics of examples 1 to 5 is better than that of the lower layer, which indicates that the specific unidirectional moisture-conducting function is achieved, and the index grades of the dynamic transmission performance of the liquid water of examples 1 to 5 reach 5 grades (the higher the grade is, the better the performance is). This is because the outer layer 1 and the middle layer 2 both use modified polyester fiber yarns, which have a much greater moisture absorption capacity than the facing material component (cotton/polyester amide) of the inner layer 3, thereby forming a differential moisture absorption between the outer layer 1 and the inner layer 3 of the fabric due to this difference in moisture absorption, indicating that the fabric has a rapid moisture absorption capacity.
Second, testing antistatic Properties
The fabrics of examples 1 to 5 and comparative example 1 were tested according to the charge surface density method in GB/T12703.1-2008 "evaluation of textile Electrostatic Properties", and the data are shown in Table 2.
Table 2 charge density test results for each group of fabrics
Figure BDA0003506789110000132
Figure BDA0003506789110000141
As is clear from Table 2, the charge density of each group was less than 7 μ C.m-2And the standard of the antistatic fabric is met, so that each group can realize antistatic. According to the data, the charge surface density of the comparative example 1 is far greater than that of the examples 1-5, which shows that the antistatic capacity of the fabric can be improved by the modified polyester fiber yarn.
Third, mechanical property test
1. And (3) testing tensile strength: the swatches were tested using the standard GB/T3932.1-1997. The samples of example 1 and comparative example 1 were cut out and tested on a tensile tester.
2. And (3) testing the tearing strength: the test sample is tested for tearing strength by selecting the standard GB/T3917-1997, the test sample is the fabrics of the example 1 and the comparative example 1, and the test is carried out in two parts of divided warp and weft. The details are shown in Table 3.
Figure BDA0003506789110000142
As can be seen from Table 3, the mechanical properties of example 1 are better than those of comparative example 1, which shows that the modified polyester fiber yarn can improve the mechanical properties of the fabric.
