NOVELTY - Preparing an acrylic fiber involves taking ceramic powder composition and modified graphene. The ceramic powder composition is dispersed in deionized water. The coupling agent is added. The polyacrylonitrile solution is uniformly mixed to obtain a cortical material. The modified graphene is dispersed in deionized water. The polyacrylonitrile solution is added and mixed to obtain core material. The cortical material is coated on the core material to form an acrylic fiber with a core-sheath composite structure. USE - Method for preparing an acrylic fiber (claimed). ADVANTAGE - The method enables to prepare an acrylic fiber by ensuring easy dyeing durability in cost-effective manner.
