Abstract  The flame retardant of new structural polysulfonamide fiber was discussed.Electrospinning device was adopted to prepare the corn-spun yarn with the polyester,vinylon,polysulfone as corn fibers and nano polysulfone fiber as covering fibers.The linear density and strength of each spun yarn and the flame retardant of their woven fabrics were tested.The test results showed that the flame retardant of fabrics were improved with the existing of nano polysulfone fiber.After covering with nano polysulfone fiber,the yarn breaking strength was slightly increased.It is considered that the corn-spun yarn combines the advantage of binary fibers.The advantage of the mechanical property for cornspun yarn is well taken.Meanwhile,the high temperature retardant and flame retardant of polysulfone fiber are also well played.
