In an alternative embodiment, the predetermined pressure interval is 0-15 newtons. In another alternative embodiment, the predetermined pressure interval is between 0.15 and 10 newtons.
On the basis of the method for detecting the fabric friction coefficient in the first embodiment, the embodiment also provides a method for detecting the fabric friction coefficient. In the method for detecting the friction coefficient of the fabric in the embodiment, the fabric to be detected is subjected to a dry test and a wet test respectively.
The test environment is set according to the temperature and humidity environment of the standard atmosphere specified in GB/T6529. Wherein, the temperature: 20 ± 1 ℃ (degrees celsius), relative humidity: 65 plus or minus 2 percent. Before the testers participate in the test, the testers enter a test environment in advance to adapt for at least 10 minutes, and meanwhile, the skin of the tested part is washed by alcohol.
The flow of the dry state test is as follows. First, the fabric was conditioned, i.e., placed in the test environment described above and held for 6 hours. The fabric was then flattened and fixed to a force plate 101 and the tester applied 150 rubs against the fabric. The specific movement mode is as follows: the movement time of 20 seconds is taken as a period, and the movement is carried out for 15 times, wherein each period comprises 10 times of one-way friction. The contact pressure is controlled within the range of 0-10 newtons, the motion displacement is controlled within the range of 50-100 millimeters, the moving speed is controlled within the range of 50-150 millimeters per second, and the preset sampling frequency is 125 hertz (in other alternative embodiments, the preset sampling frequency is in the range of 60-180 hertz). The friction coefficient output unit 102 records the friction value and the pressure value of the one-way friction for 10 times in each cycle, and generates a variation curve as shown in fig. 7. Wherein, the abscissa is time, the unit is second, the ordinate is force, the unit is ox, the first curve 301 represents the change curve of the pressure value, the second curve 302 represents the change curve of the friction force. Next, the friction coefficient output unit 102 acquires the average coefficient and the coefficient variance, and details of the acquisition manner are omitted here.
The procedure for the wet test is as follows. The conditioned fabric was weighed. Then, the fabric is completely put into distilled water, and the fabric is reweighed to ensure that the water content of the fabric reaches 95% -100%. The fabric was then flattened and fixed to a force plate 101 and the tester applied 150 rubs against the fabric. The specific movement mode is as follows: the movement time of 20 seconds is taken as a period, and the movement is carried out for 15 times, wherein each period comprises 10 times of one-way friction. The contact pressure is controlled within the range of 0-10 newtons, the motion displacement is controlled within the range of 50-100 millimeters, the moving speed is controlled within the range of 50-150 millimeters per second, and the sampling frequency is 125 hertz. The friction coefficient output unit 102 records the friction value and the pressure value of 10 times of one-way friction in each period and generates a change curve. Next, the friction coefficient output unit 102 acquires the average coefficient and the coefficient variance, and details of the acquisition manner are omitted here.
In specific implementation, 5 different types of cloth samples of the medical pressure socks are selected as detection objects, wherein the detection objects comprise traditional and improved pressure socks, and the pressure grade of the detection object is grade 2 (the grade 2 medical pressure socks are the most widely used products in clinic).
These 5 kinds of detection targets were divided into the following 3 groups as shown in table 1.
A first group: conventional medical pressure sock specimen S1. The fabric material is 70% of chinlon and 30% of spandex fiber, and the bottom structure is a weft plain stitch 2 x 1 variable structure.
Second group: pressure sock samples S2 and S3. The material composition is changed on the basis of the fabric material of S1, cotton and Tencel (Tencel) fibers are respectively added into the embedded yarn, and the bottom weave structure is unchanged.
Third group: pressure sock samples S4 and S5. The ground weave structure was changed on the basis of the woven material of S1, with the weft plain 1 x 1 warp loop yarns and the straight insert yarns, but with a similar material composition to S1.
TABLE 1 basic characteristics of the compression sock specimens to be tested
According to the method for detecting the fabric friction coefficient of the embodiment, the test objects are respectively subjected to a dry test and a wet test, and the obtained test results are shown in table 2, which are the dry-wet friction results of all the test objects under the contact pressure of 0-10 newtons. It can be seen that the friction coefficient of all the test objects is higher in the wet state than in the dry state, and the friction coefficient in the wet state is about 1.21 to 2.69 times that in the dry state.
In the dry state, the friction coefficient of all the test objects was about 0.36, and the friction coefficient between the test objects did not show a significant difference. Whereas the coefficient of friction of the pressure sock samples of varying materials and structures (samples S2, S3, S4, S5) is lower than that of the conventional pressure sock sample (S1) in the wet state. The friction coefficients of samples S2 and S3 were about 20% to 30% lower than S1, while the friction coefficients of samples S4 and S5 were about 58% to 60% lower than S1. Meanwhile, the friction coefficient distribution range of each detection object is wide, especially under the wet condition. The dry and wet coefficients of friction of both samples S4 and S5 are seen to be in a relatively narrow range when compared to the conventional compression sock sample (S1).
TABLE 2 mean and variance of dry and wet friction coefficients of compression sock samples at 0-10N contact pressure
Improving the uneasiness of wearing and comfort of medical pressure socks is a current problem to be solved, and both problems are related to the friction performance when the pressure socks are in contact with the skin. Therefore, in the present embodiment, the friction force measured when the tester places the inner skin of the forearm on the force plate 101 to which the fabric is adhered and reciprocates back and forth, and the contact pressure indicate the friction performance when the medical pressure sock is in contact with the skin, and the fabric material of the medical pressure sock can be selected and improved according to the friction performance.
