METHOD FOR MANUFACTURING COMPOSITE FIBER OF HEMP
First Claim
1. A method for manufacturing composite fiber of hemp, including steps of:
- preparing hemp material;
cutting stem of hemp into pieces, drying and charring the pieces of hemp at 800 to 1200 degrees Celsius and grinding the pieces of hemp into powder to form a hemp material;
preparing primary granule;
mixing the hemp material and main granules in a weight ratio of 5-20;
95-80 wherein the main granules are selected from a group composed of nylon granules or polyester granules, melting and granulating the hemp material and main granules to form primary granules;
preparing mixed granules;
mixing and melting the primary granules and main granules in a weight ratio of 5-20;
95-80 and granulating to form mixed granules;
spinning;
melting the mixed granules to spin into a composite fiber.
