Comparative example 1
The reducing agent was replaced with 100mL of methanol as compared with example 6, and the other conditions were the same as in example 6.
The wearability of the silver-plated wave-absorbing fabric prepared in the examples 1-6 and the comparative example 1 is measured:
according to GB/T5453-1997 determination of the air Permeability of textiles, a digital air Permeability apparatus of YG461E was used at a pressure difference of 100 (Pa/mmH)2O) testing the air permeability of the prepared product; according to GB/T12704.1-2009 part 1 of textile fabric moisture permeability test method: wet absorption method, adopting YG 601-I/II type computer type fabric moisture permeameter to test the moisture permeability of the product at 38 deg.C and 50% relative humidity; according to GB/T21196-2007 test for the wear resistance of fabrics by the Martindale method, a Y522 type disc type fabric plain grinding instrument is adopted to test the wear resistance of the prepared product under the conditions of the pressurization weight of 800cN and the rotation number of 200 revolutions, and the test results are shown in Table 2.
TABLE 2
As can be seen from Table 2, the air permeability of silver-plated cotton fabric is superior to that of silver-plated polyester-cotton blended fabric, and the air permeability of silver-plated jean cotton fabric is substantially the same as that of silver-plated cotton fabric. The silver-plated polyester non-woven fabric has the best air permeability, and is formed by melt spinning, high-speed drafting, cooling and crystallizing, so that the air permeability is the best. The silver-plated polypropylene fiber non-woven fabric is formed by high-temperature wire drawing, so that the process is simple, and the air permeability of the silver-plated polypropylene fiber non-woven fabric is slightly lower than that of the silver-plated polyester fiber non-woven fabric. The air permeability and the moisture permeability of the fabric are in direct proportion, namely the better the air permeability of the fabric is, the better the moisture permeability is. Of the 6 silver-plated fabrics, the silver-plated denim fabric has the best wear resistance. Although the non-woven fabric is the same as the silver-plated polyester non-woven fabric, the silver-plated polyester non-woven fabric and the silver-plated polypropylene non-woven fabric have different process flows and different gram weights, so that the wear resistance of the fabrics is different. The abrasion resistance of the fabric is better than the gram weight of the fabric, and the heavier the fabric is, the better the abrasion resistance is. The silver-plated polyester non-woven fabric has good air permeability and poor wear resistance. The abrasion resistance of the cotton-containing fabric was not much different.
The wave absorbing performance of each material of the silver-plated wave absorbing fabrics prepared in examples 1 to 6 and comparative example 1 was measured by a vector network analyzer, and the results are shown in fig. 2 and fig. 3.
Fig. 2 shows the result of the wave-absorbing property test of Ku waveband, and it can be seen from fig. 2 that the wave-absorbing effect of the products prepared in examples 2 and 3 is general, and the wave-absorbing property is low because the fabrics used in the wave-absorbing material are all non-woven fabrics, the non-woven fabrics have large pores, the fabrics are light and thin, the impregnation capability is strong, and the chemical silver plating is immersed in the fabrics. The better the wave absorbing effect of the product prepared in the embodiment 2 along with the increase of the frequency, and at the frequency of 16GHz, the reflectivity of the product prepared in the embodiment 2 is at least-6 dB, and the absorptivity is 74.9%. And the reflectivity of the fabric of the product prepared in the example 1 is gradually increased and the absorptivity is gradually reduced along with the increase of the frequency. Comparing the products prepared in the examples 1 and 2, it can be seen that the wave-absorbing effect of the cotton fabric is better than that of the polyester-cotton blended fabric, the wave-absorbing effect is slightly poor due to the poor conductivity of the polyester fiber because of the low hygroscopicity of the polyester fiber, and the wave-absorbing effect of the product prepared in the example 1 is better than that of the product prepared in the example 2 because of the good conductivity of the cotton fiber because of the good hygroscopicity of the cotton fiber. When the frequency of the product prepared in the embodiment 5 is 18GHz, the reflectivity of the fabric is low at-8 dB, the absorptivity of the fabric is 84.2dB, and the wave-absorbing effect of the product prepared in the embodiment 6 is 90% optimally. Comparing the products prepared in the embodiment 2 and the embodiment 6, it can be seen that the products are both cotton-containing fabrics, but the wave absorbing effect of the product prepared in the embodiment 6 is far better than that of the product prepared in the embodiment 2, because the denim jeans is thick and solid, the density is higher, and the fabric is compact, therefore, when the fabric is the same, the thicker the fabric is, the better the density is, and the better the wave absorbing effect of the fabric after silver plating is.
FIG. 3 shows the test result of the wave-absorbing performance of the X wave band, and it can be seen from FIG. 3 that the reflectivity curves of the products prepared in examples 1, 2, 3 and 4 are substantially consistent in the range of frequency 8-12GHz, and the reflectivity of the silver-plated fabric is gradually reduced and the wave-absorbing effect of the fabric is gradually improved as the frequency is increased. The products prepared in examples 3 and 4 have slightly poor wave-absorbing effect. Compared with the products prepared in the examples 1 and 2, the wave absorbing effect of the polyester-cotton blended fabric is slightly inferior to that of the cotton fabric. The wave absorbing effect of the products prepared in the embodiments 5 and 6 is better than that of the other four silver-plated wave absorbing fabrics, when the frequency of the product prepared in the embodiment 5 is 11GHz, the reflectivity reaches-10 dB, the absorptivity reaches 90%, the reflectivity curve diagram of the product prepared in the embodiment 5 shows that the reflectivity is reduced and then increased, but the fluctuation is not large in the general view; the reflectivity of the product prepared in the embodiment 6 reaches-12 dB and the absorptivity is 93.7% at the frequency of 8GHz, and the reflectivity curve diagram of the product prepared in the embodiment 6 changes stably and keeps around-12 GHz when the frequency of the product is 8-9GHz, which shows that the wave-absorbing effect of the silver-plated wave-absorbing fabric is good and stable.
In conclusion, the wave absorbing effect of the 6 different silver-plated wave absorbing fabrics in the X waveband is far better than that of the Ku waveband, but the wave absorbing effect of the fabric is not obviously improved in any waveband of the silver-plated wave absorbing fabrics prepared in the embodiments 3 and 4, and the wave absorbing effect of the fabric is not good in any waveband of the silver-plated wave absorbing fabrics prepared in the embodiment 6, which indicates that the denim jeans is more suitable for being used as a coating fabric, and the wave absorbing effect of the cotton fabric is better than that of the polyester-cotton blended fabric.
