1、many further attempts were made by the military during world warsⅠandⅡto reduce fire hazards by introducing fire-retardant treatments and suitable clauses in fabric specifications
2、only in 1952,following a number of deaths from garment fires , were the hazards from Flammable Fabric Act of 1952,regulating flammability of textile products purchased directly by consumers . Subsequently the 45° angle test was accepted as a commercial standard in the United States with the aim of indicating textile used for apparel “which ignite easily and ,once ignited ,burn with sufficient intensity to be hazardous when worn .”
3、it was also realized that compromises would have to be reached between the degree of protection the cost of protection . Tribus illustrated this trade-off as an exercise in risk-taking: the induction in the number of burns expected for a given standard is plotted against the severity of the tests required by it and against the cost .
4、Of great importance are the physiological properties that may be impaired-comfort ,smell ,water absorption and heat of water absorption ,migration of dyes and finishes to skin ,and possible health hazards-by irritation of the skin or by absorption through the skin of the flame retardant or of another dyestuff or finishing chemical “activated ” by the flame retardant .
