Performance test

The air permeability of a fabric is mainly expressed by testing the permeability of air to the fabric (air permeability), which directly affects the functionality and the wearability of the fabric. The fabric with good air permeability can enable sweat of a wearer to volatilize freely without causing stuffiness, and has good serviceability.

And (3) testing the air permeability of the fabric: the test sample is tested according to the international standard ISO 9237, and the test result is shown in Table 2. The method specifically comprises the following steps: after humidifying the sample, selecting a proper sample area and pressure drop, fixing the sample in a place without wrinkles, opening a fan, adjusting the air flow, and recording the air flow after the pressure is close to a specified value for 1 minute. The test was repeated at least 10 times under the same conditions. The larger the average air flow, the better the air permeability of the fabric. In each of examples 1 to 5 and comparative examples 1 to 3 below, the number of specimens was 10, and the test area was 20cm²The applied pressure was 100 Pa.

TABLE 2

	Average air permeability/L.m-2·s-1
		Example 1	35.7
Example 2	37.4
		Example 3	36.3
Example 4	36.9
		Example 5	33.8
Comparative example 1	27.2
		Comparative example 2	33.7
Comparative example 3	31.2

As can be seen by combining examples 1-3 and table 2, the composite polyester fabric prepared by the preparation method in the present application has good air permeability, wherein example 2 is preferred.

By combining example 2 and example 4 and table 2, it can be seen that the air permeability of the composite polyester fabric in example 4 is similar to that of the composite polyester fabric in example 2.

As can be seen by combining example 2 and example 5 and table 2, the air permeability of the composite polyester fabric in example 5 is less than that of the composite polyester fabric in example 2.

The reason for this may be: in example 5, the ratio of polyester fibers in the weft yarn is increased, and the ratio of spandex is decreased.

As can be seen by combining example 1 and comparative example 1 and table 2, the air permeability of the composite polyester fabric in comparative example 1 is significantly less than that of the composite polyester fabric in example 1.

As can be seen by combining example 1 and comparative example 2 and table 2, the air permeability of the composite polyester fabric in comparative example 2 is less than that of the composite polyester fabric in example 1.

As can be seen by combining example 1 and comparative example 3 with table 2, the air permeability of the composite polyester fabric in comparative example 3 is less than that of the composite polyester fabric in example 1.

The present embodiment is only for explaining the present application, and it is not limited to the present application, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present application.
