[0040]
[0041] Table 1
[0042] The test steps are as follows:
[0043] A mattress hardness test instrument is used to perform static loading on the bed net. The steps are as follows.
[0044] Step 1: Place the bed net product at the center of the test rigid tabletop, move the support crossbeam and the national learning test device, so that the center of the spherical segment-shaped indenter is directly above the test point of the bed net.
[0045] Step 2: Perform preloading on the bed net: The spherical segment-shaped indenter descends at a uniform speed of 90 mm / min. When the indenter load reaches 1200 N, hold the load for 30 s, and then unload to a load of 0 N at the same speed. Repeat the loading and unloading 3 times.
[0046] Step 3: During the experimental test, the spherical segment indenter descends uniformly at a speed of 90 mm / min and acts on each discrete test point of the specimen. After the indenter load reaches 1000 N, it is immediately unloaded to a load of 0 N at the same speed, and the test is repeated 3 times.

The greater the pressure value, the stronger the support; the soft-hardness grades are similar.
[0053] ② When comparing the high-compression 1.8 wire with the ordinary 1.9 wire, when compressed to 10 cm, the pressure values are similar; when compressed to 15 cm, the pressure values are similar. The greater the pressure value, the stronger the support; the high-compression is harder in terms of the soft-hard grade.
[0054] ③ Conclusion: When comparing the high-compression 1.6 wire with the ordinary 1.7 wire / when comparing the high-compression 1.8 wire with the ordinary 1.9 wire, the support of the high-compression ratio is better than that of the ordinary spring.
