Problems solved by technology

However, due to the high crystallinity of flax fiber, the macromolecules are arranged neatly and densely, and the gap space is small. Low, high degree of orientation of flax fiber, high degree of combination of macromolecular arrangement direction and fiber axial direction, resulting in high fiber tensile strength, low elongation ability, poor elasticity, small space that dye macromolecules can occupy during dyeing, and low permeability , poor penetration, low color fastness, these problems of flax fiber seriously restrict the development of high-grade flax products

Abstract

The invention discloses a treatment method for improving a dyeing property of flax fibers for fabrics. The treatment method is characterized by comprising the following steps: (1) soaking treatment; (2) proton irradiation treatment; (3) high pressure treatment; and (4) dyeing treatment. The invention provides the treatment method for improving the dyeing property of the flax fibers for the fabrics, the crystallinity of the flax fibers is reduced, molecular arrangement of flax molecules is changed, and softness of the flax fibers is improved, thus, the dyeing property of the flax fibers is improved, the dyeing rate of the flax fibers is increased, the color fastness of the flax fibers is improved, and the treatment method has great market popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of fabric processing, and in particular relates to a treatment method for improving the dyeing properties of flax fibers used for fabrics. Background technique [0002] Linen is one of the earliest natural fibers used by humans, with a history of more than 10,000 years. Flax fiber is a rare natural fiber, accounting for only 1.5% of the total natural fibers. Because of its natural, simple, rare, natural and noble colors, it is known as "the queen of natural fibers". Flax fiber has many excellent properties. It absorbs moisture and dissipates heat, maintains health and inhibits bacteria, is anti-fouling, anti-static, anti-ultraviolet, and has excellent flame retardant effect. However, due to the high crystallinity of flax fiber, the macromolecules are arranged neatly and densely, and the gap space is small. Low, high degree of orientation of flax fiber, high degree of combination of macromolecular arrange...
