Embodiment 5
Shield effectiveness uses DR-913 type testing anti-electromagnetic radiation function of fabrics instrument, reference standard GB/T25471 " electromagnetic shielding
The shield effectiveness measuring method of coating " and SJ204524 " method of testing of Materials ' Shielding Effectiveness " test.
Soaping fastness measures according to GB ISO1051001-1989 method, then evaluates the capability of electromagnetic shielding of fabric, Yi Jishi
Fading and adjacent fabric staining grade of sample.
Fabric shield effectiveness and soaping fastness is measured, result such as table 1,2 by above method:
Table 1 fabric electromagnet shield effect
As can be seen from Table 1, embodiment 1-4 gained Electromagnetically shielding fabrics has well screen to the low-frequency electromagnetic wave of below 10MHz
Covering performance, shield effectiveness reaches more than 18dB, and after washing, electromagnet shield effect slightly reduces.Dyestuff used by comparative example 1
Active red 3BS cannot form conducting polymer by chemical polymerization, and gained fabric is without capability of electromagnetic shielding.After comparative example 2-4 dyeing,
Without chemical polymerization, forming conductive polymer coating the most on the textile, gained fabric is also without capability of electromagnetic shielding.
