NOVELTY - Modified fiber with antistatic performance for mattress fabric comprises 50-60 wt.% polyester fiber, 20-30 wt.% polyurethane fiber, 10-20 wt.% wool fiber, 5-10 wt.% silk fiber and 0.5-1.5 wt.% conductive fiber. The conductive fiber is 85-95 wt.% poly-sebacic acid decyldiamine, 15-20 wt.% m-phthalic acid hexamethylenediamine-terephthalic acid hexamethylene diamine co-polyamide, 4-6 wt.% graphene and 3-5 wt.% vinyl bisstearamide. The graphene is copolymer of conductive polymer and edge oxidation nano graphene microsheet. The fiber is modified by antistatic agent. USE - Used as modified fiber with antistatic performance for mattress fabric. ADVANTAGE - The fiber: has evenly dispersed antistatic component; is not easy to fall off and durable, and has significant effects. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for preparing modified fiber comprising (a) (a1) adding the graphene into aqueous solution of sodium hexametaphosphate, adding montmorillonite and jojoba oil to obtain solution A, stirring, taking monomer into the solvent to prepare into solution, adding into three-mouth flask, mechanically stirring and slowly adding solution A, gradually adding ammonium persulfate solution under the condition of ice water bath, continuing ice water bath reaction, filtering, washing, soaking, drying to obtain the copolymer of conductive polymer and graphene, (a2) weighing the raw material of the conductive fiber, uniformly mixing the raw materials by a stirrer, drying, sending the mixed raw material into a single-screw extruder to melt into a mixed melt, (a3) placing the mixed melt into the spinning machine, melt distributing, spraying out from the spinneret plate, forming a filament, cooling by blowing, oiling, stretching, winding, obtaining conductive fiber, (b) (b1) weighing each fiber component to the needed proportion and mixing, placing the mixed fiber into a crusher for crushing, crushing and sieving to obtain the fiber powder, (b2) soaking the fiber powder into sodium hydroxide solution, controlling the temperature of the solution, stirring, centrifuging, washing with ethanol, drying until the water content is 3-0.5%, (b3) soaking the processed fiber powder into acetone solution, stirring, centrifuging, washing with ethanol, drying until the water content is less than 0.5%, (c) dissolving the antistatic agent in deionized water, stirring uniformly, soaking the fiber powder for 10-12 hours to obtain the mixed solution and (d) placing the mixed solution into the spinning tank for spinning treatment, forming by conventional curing, water washing and stretching and drying to obtain the modified fiber.
