NOVELTY - A multi-fiber comprises 80-100 pts. wt. polyester fiber, 20-30 pts. wt. PVC, 10-20 pts. wt. graphene fiber, 2-4 pts. wt. plasticizer, 6-10 pts. wt. disperse dye, 2-4 pts. wt. dispersant, 2-4 pts. wt. dyeing additive, 6-10 pts. wt. soybean lecithin, 4-6 pts. wt. Vanilla leaves and 6-10 pts. wt. microprism. USE - Multi-fiber. ADVANTAGE - The multi-fiber has high strength, fragrant smell, fast dyeing property, can effectively prevent bacterial growth, and is not easily deformed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of the multi-fiber, which involves forming a masterbatch, cutting the graphene fiber and polyester fiber into small sections, uniformly mixing in a mass ratio of 1:1, adding the mixture into plastic granulator to prepare polyester graphene mixed masterbatch, cutting Vanilla leaves into small pieces, placing the small pieces into a mortar, adding water, crushing and grinding, immersing the ground Vanilla leaves into ethanol to extract Vanilla essential oil, cutting the polyester fiber into small pieces through plastic granulator to make polyester particles, mixing the polyester particles and masterbatch, adding plasticizer and soybean lecithin, mixing the mixture using spinning machine to form mixed fiber, drying, cooling, adding PVC, Vanilla essential oil, microprism and plasticizer into the coating machine to form a coating layer, coating the mixed fiber through coating machine, adding coating layer on the outer layer of the mixed fiber, cooling, mixing the disperse dye with water, soaking the mixed fiber in the dye, continuously heating during dyeing process, drying the mixed fiber, packaging and storing.
