On the safety of flame retardant textiles in high temperature environment

为保证纺织品的安全，阻燃处理技术得到了发展。本文测量了氧指数（OI）表示不可燃性、燃烧速度和燃烧气体浓度。实验用的样品有聚甲醛（PC）、PBI （PB）、f.r.m adacryle （PT）、棉花及其混纺。PB、PC、PT和棉花的OI分别为36.0、30.7、29.8和18.0。掺混50% f.r.纤维的样品OI最高。利用高速摄像系统测定了燃烧速度。纺织品的OI值较高，燃烧速度较慢。用气相色谱法对燃烧气体进行分析。在每1m空气1g样品的燃烧气体中，PB、PC和PT的CO浓度分别为51.4ppm、32.2ppm和25.6ppm。随着混纺棉样品的减少，在PB和PT上检测到CO.HCN的生成。

For the safety of textiles, flame retardant treatment has been developed.In this paper, oxygen index (OI) indicated nonflammability, combustion speed and concentration of combustion gas were measured. Samples used in the experiment are polychlal (PC), PBI (PB), F.R.Modacryle (PT), cotton and their blend.OI measured on PB,PC,PT and cotton were 36.0,30.7,29.8 and 18.0. Sample blended 50% F.R.fiber showed highest OI.Velocity of combustion was determined using a high speed video camera system. The textiles retained high OI indicated slow combustion speed.Combustion gases were analyzed by a gas chromatography. On the combustion gasees of sample of 1g per 1m air, CO concentration of PB,PC and PT were 51.4ppm, 32.2ppm, 25.6ppm. As samples blended cotton were decreased a generation of CO.HCN was detected on PB and PT.
