Abstract

The invention relates to a method for enhancing the property of a ramie fiber through oxidative degumming. The method comprises the following steps of mixing original ramie and a peroxide degumming solution according to mass ratio being 1 to 10, boiling for 40-60 minutes under the condition of 80-85 DEG C, wherein with respect to the weight percent of the original ramie, the peroxide degumming solution comprises the following components by weight percent: 1%-4% of sodium hydroxide, 3%-8% of peroxides, 0.5%-4% of quinones compounds, 1%-6% of a metal ion chelating agent, 2%-4% of a peroxide stabilizing agent, 2%-6% of a surface active agent and the balance being water; adding sodium hydroxide, boiling for 1-1.5 hours under the condition of 100 DEG C to obtain treated ramie; boiling the treated ramie and a reducing solution at 60-100 DEG C for 40-90 minutes, then applying oil, and drying. According to the method disclosed by the invention, needed degumming time is short and the efficiency is high and the bleaching and the degumming can be completed together; the prepared ramie fiber has good tensile property.

Description

technical field

[0001] The invention belongs to the field of methods for improving fiber properties, in particular to a method for improving ramie fiber properties through oxidation degumming. Background technique

[0002] Ramie is a perennial herbaceous plant belonging to the family Ramieceae. It is a unique textile material in China. It has strong adaptability to climate and soil, short harvest period and high economic value. Ramie fiber is long, high strength, white and mercerized in color. In the field of clothing, its fabric has the characteristics of crispness, coolness, fast moisture absorption and heat dissipation, and not close-fitting, and can be processed into fine or rough fabrics. In the field of industrial use, it can be used as a raw material for aircraft wing cloth, fishing nets, high-grade paper, gunpowder, and rayon due to its corrosion resistance, insulation, and antibacterial properties.

[0003] The main component of ramie fiber is cellulose, and the n...
