Problems solved by technology

At present, the commonly used degumming method is the chemical caustic soda high-pressure scouring method. This method produces a large amount of acid-base wastewater and causes serious environmental pollution. Therefore, many companies are conducting enzymatic ramie degumming tests. The process flow is: binding→installation Cage→en

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of hemp degumming, belongs to the field of textiles, and in particular relates to a ramie degumming method suitable for close-fitting fabrics. Background technique [0002] Ramie (scientific name: Boehmeria nivea (L.) Gaudich.) Urticaceae Ramie is a subshrub or shrub plant. Alias: (Bielu of famous doctors) wild hemp (Guangdong, Guizhou, Hunan, Hubei, Anhui), wild ramie (Guizhou, Zhejiang, Jiangsu, Hubei, Henan, Shaanxi, Gansu), home hemp (Jiangxi), ramie (Taiwan) , green hemp (Guangxi, Hubei), white hemp (Guangxi). [1] [0003] Ramie is one of the important fiber crops in ancient China. Native to Southwest China. It has been planted in some places in the middle and lower reaches of the Yangtze River in the Neolithic Age. The earliest archaeological unearthed is the ramie cloth and fine hemp rope unearthed from the Neolithic site in Qianshanyang, Zhejiang, more than 4,700 years ago. China is a country w...
