Effect of fabric structures on flame retardant property of Anti-fcell~ fabrics

To improve the flame retardant property of Anti-fcell flame retardant fabric,the effects of yarn linear density,twist,structure,warp density,and surface density etc on Anti-fcellfabrics′flame retardant(FR) property were investigated using limiting oxygen index(LOI) test.The results showed that the FR property of the double-layer fabrics were better than that of the monolayer fabrics.The LOI value of these double-layer fabrics were all above 31.0%.Higher the density,yarn linear density and twist of the double-layer fabric,better its FR property.In addition,the FR properties of Anti-fcell/FR-PET and Anti-fcell/ wool mixed nonwoven fabric were investigated.It was found that the LOI value of Anti-fcell/FR-PET mixed nonwoven fabric was higher than 26% when Anti-fcell iber contained more than 60%.And the LOI of Anti-fcell/wool mixed nonwoven fabric was higher than 26.5% when Anti-fcell iber contained more than 25%.
