[0126] The modified polyester fiber prepared in Examples 7-12 and Comparative examples 1-5 were tested for the tensile strength, the elongation at fracture, the bending property. The mesh was further weaved by the modified polyester fiber of corresponding Examples and Comparative examples, and the tensile strength of the corresponding mesh was tested. The test method and the test data were shown as follows.
1) Test Method
[0127] (1) Tests of the tensile strength and elongation at fracture were tested according to GB/T14344-2008 testing method for tensile of man-made filament yarns. In particular, the gripper was moved at a speed of 250 mm/min;
[0128] (2) Bending test: a modified polyester fiber was folded in half and compacted under a pressure of 3 atmospheres for 1 hour to observe whether there was a crease at the folded portion of the modified polyester fiber.
[0129] (3) Tests of the tensile strength of mesh: a mesh sample with a length of 50 cm and a width of 5 cm was cut, and tested for the tensile strength at a tensile speed of 50 mm/min.

[0130] According to above data, the modified polyester fiber prepared in the present application has a good tensile strength, a good flexibility, and a good bending resistance, and is not easy to deform and can maintain a good tensile strength after bending. The mesh weaved by the modified polyester fiber can be applied to be a mesh-shaped vertical drawing strap 3 and a mesh-shaped inclined diaphragm 5, such that a good connection and a good drawing stability of the inflatable bed can still be maintained after being deflated and folded for many times.
[0131] The usage amount of the polyamide-6 in Comparative example 1 was relatively low, there is no polyamide-6 in Comparative example 3, the tensile strength and the elongation at fracture of the modified polyester fiber were increased a little, however, there was an obvious crease at the folded portion of the fiber, and the tensile strength of the modified polyester fiber after bending was decreased significantly, which indicated that addition of polyamide-6 to the polyester masterbatch to be modified can improve the tensile strength and the flexibility of the modified polyester fiber, and enables the modified polyester fiber to possess a good flexibility and a good bending performance while resisting wrinkles. When the modified polyester fiber is applied to the mesh-shaped vertical drawing strap 3 and the mesh-shaped inclined diaphragm 5 of the inflatable bed, the inflatable bed can maintain a good connection and drawing function after being deflated, folded and inflated for many times.
[0132] The usage amount of the polyamide-6 in Comparative example 2 was excessive, the tensile strength and the elongation at facture of the prepared modified polyester fiber were decreased, compared with that of Example 10. The reason is that, the polyamide-6 itself has a flexibility and an elasticity, which reduces the tensile strength of the polyester fiber when the usage amount of the modified polyester fiber is excessive.
[0133] There was no kapok fiber in the modified filler in Comparative example 4, and there was no nano zinc oxide in the modified filler in Comparative example 5, the tensile strength and the elongation at fracture of the prepared modified polyester fiber were both decreased, the tensile strength of the modified polyester fiber after bending was decreased, and the tensile strength of the mesh was decreased as well, which indicated that the modified filler prepared by the nano silica, the nano zinc oxide and the kapok fiber can effectively improve the tensile strength and the flexibility of the polyester fiber, and further improves the tensile strength of the mesh weaved.
[0134] The above are the preferred embodiments of the present application, which are not intended to limit the protection scope of the present application. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
