[0121] III. Methods

[0122] 3.1 Endurance test

[0123] 1) Experimental procedures

[0124] ① Prepare 10 cable ties (the specification of the cable tie 1 is: 2.5mmx100mm) by the preparation methods of Examples 1-3 and Comparative Examples 1-4 respectively;

[0125] ② Use a steel needle to pierce 10 through holes at fixed points in the same area on each root tie;

[0126] ③ Use a tensile testing machine to test the tensile strength of each cable tie;

[0127] ④ Take the average value of the data of the cable ties prepared in the same embodiment or comparative example and record it as follows:

[0128] Table 1

[0129] project Average tensile strength Example 1 111 lbs Example 2 120 lbs Example 3 161 lbs Comparative Example 1 67 lbs Comparative Example 2 79 pounds Comparative Example 3 91 lbs Comparative Example 4 98 lbs

[0130] It can be seen from the above table that the cable tie prepared in Example 3 is the best compared with Examples 1-2 and Comparative Examples 1-4. The cable tie made of flax fiber filaments, cotton fiber filaments and modified latex in a suitable proportion still has good tensile strength in a damaged state, which helps to prevent the cable tie from breaking easily when tying objects with barbs on the surface.

[0131] 3.2 Roughness experiment

[0132] 1) Experimental procedures

[0133] ① Prepare 10 cable ties (the specification of the cable tie 1 is: 2.5mmx100mm) by the preparation methods of Examples 1-3 and Comparative Examples 1-4 respectively;

[0134] ② Use a friction coefficient tester to test the friction coefficient of each cable tie surface;

[0135] ③ Take the average value of the data of the cable ties prepared in the same embodiment or comparative example and record it as follows:

[0136] Table 2

[0137] project Average friction coefficient Example 3 0.81 Comparative Example 5 0.3 Comparative Example 6 0.33 Comparative Example 7 0.42

[0138] It can be seen from the above table that compared with comparative examples 5-7, the cable tie prepared in Example 3 is the best, and the cable tie made of volcanic rock and ceramics in a suitable proportion has the largest surface friction coefficient. Under the same usage mode, the cable tie can be better positioned on the surface of the tied object, thereby making the cable tie more secure.

[0139] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
