The invention discloses a ramie degumming method suitable for a close-fitting fabric. The method comprises the following steps: adding vegetable oil before the traditional enzyme treatment, and pretreating fiber bundles, wherein a small amount of the added vegetable oil can infiltrate into the fiber interior and fiber surface so as to achieve a certain protective effect on the fiber structure, and the condition that the strength of the ramie is greatly damaged by subsequent ultrasonic treatment is avoided; adding pelelith, namely treating the fiber surface by referring to a stone wash process, wherein the particle size of the pelelith is controlled to 2-5mm so as to prevent the pelelith of large particle size from causing great damage to the fibers under the ultrasonic action, and if the particle size is too small, the grinding effect on the fiber surface is not obvious. In conclusion, the ramie degumming method disclosed by the invention is actually a degumming method of integrating biological enzyme degumming, ultrasonic treatment and stone wash treatment, the degummed ramie fibers have good degumming effects, and the indexes of the fibers such as breaking strength, whiteness and the like meet the textile requirements of the close-fitting fabric.
