Preparation and process optimization of viscose-based carbonized fabric

A type of fireproof fabric with both excellent fire retardant and good mechanical properties was prepared by dipping ordinary viscose fabric in a bath containing suitable fire retardant via suitable impregnation process and carbonizing at a certain temperature.Quadratic general rotation combination design method was used to arrange experiments and the effects of processing temperature,time and tension on the tensile breaking strength in warp or weft directions,abrasion resistance as well as limiting oxygen index(LOI) of the fireproof fabric were investigated.Relevant regression equations of different indexes were established and the optimized process parameters were determined.Results showed that tension has no obvious effect on LOI value of the fireproof fabric,while processing temperature and time have significant effect on LOI.Processing temperature has the greatest effect on tensile breaking strength of the fireproof fabric,followed by tension,and time has minimal effect.The fabric processed at 240 ℃ under a tension of 4 N for 42 min had optimal comprehensive properties.
