Abstract:

In order to potimize the designs of anti-arc fabrics, the structures and parameters of three kinds of ante-arc fabrics were analyzed, and the extensibility, breathability, moisture permeability, flame retardant, thermal stability, thermal protection and arc protection performance were tested. The influencesof fabric parameters on comfort and protection properties were also investigated. The results show that the influence of raw materials on the protection properties is the most significant, and a smoldering phenomenon exists for fabrics prepared from flame retardant nitrile and aramid. The higher the aramid content is, the better the flame retardant and thermal stability of the fabric are. For single-layer anti-arc fabrics, when the tightness increases by 13%，thermal protective performance (TPP) and arc thermal perfprmance value ( ATPV) increases by 6% and 42%, respectively, but the comfort properties decline, and the breathability and the moisture permeability reduce by 63% and 22%, respectively. The double-layer structure effectively increases the value of ATPV and TPP of anti-arc fabrics, significantly for ATPV value, and the ATPV value of double layer is three times greater than that of single layer fabrics, but comfort properties reduce weakly, and breathability and moisture permeability reduce by 4 % and 7% , respectively.
