Influence of Flame Retardant Yarn Layered Configuration Method on Fabric Flame Retardant Property.

The configuration method of reasonable flame retardant fabric specification was studied. 26 kinds of flame retardant yarn with different formations were designed and processed.35 kinds of weft double fabrics with the same texture specification and 13 weft triple fabrics with same texture specification were woven. Among them, some were formed with different flame retardant yarn with layered configuration while some were corresponding homogeneous fabric.The breaking strength, tear strength and flame retardant index of each fabric were tested. The test results showed that the mechanical properties of fabric with flame retardant fiber layered configuration was normally lower than those of homogeneous fabric.The flame retardant property was better than that of homogeneous fabric.It was pointed out that part of flame retardant fibers with lower cost or even the common fibers could be used in flame retardant fiber layered configuration.So under the condition of keeping the same flame retardant property,the cost of flame retardant fabrics could be reduced and higher cost performance could be obtained.
