Problems solved by technology

With the in-depth research of hemp fiber, in order to enhance and endow hemp fiber with various functions and use characteristics, it needs to be modified. Oxidation treatment is one of the common modification methods, which can effectively treat hemp fiber. The fiber is etched to increase the specific surface area, improve the activity of the fiber surface, enhance the binding ability with polymer substances such as glue and dyes, and improve the soft touch characteristics of the fiber, which has a good treatment effect, but the existing oxidation treatment The method has the problems of high weight loss rate and serious damage to mechanical properties.

Abstract

The invention discloses a modified treatment method for a ramie fiber for knitted goods. The method comprises the following steps: (1) cleaning treatment; (2) steam explosion treatment; (3) soaking treatment; (4) irradiation treatment; and (5) oxidation treatment. Specific modified treatment is carried out on the ramie fiber, so that the use characteristic of the ramie fiber is effectively improved, meanwhile, the problems of over-high weight loss ratio and serious mechanical property damage are also solved, and the modified treatment method has good promotional value.

Description

technical field [0001] The invention belongs to the technical field of knitwear processing, and in particular relates to a method for modifying ramie fibers for knitwear. Background technique [0002] With the rapid progress of science and technology, human society has entered a new era, accompanied by problems such as environmental pollution and shrinking available resources, which also plague people. "People-oriented", "returning to nature, returning to nature", "green environmental protection products" have gradually been valued by people in recent years and become a fashion and trend. Hemp fiber is one of the common fiber raw materials in knitwear. As a natural fiber, it is valued and loved by people for its excellent characteristics, and it presents a good development prospect. Ramie is a perennial herbaceous plant of the genus Ramie in the family Urticaceae, commonly known as "Chinese grass" and also known as "the king of fibers". Ramie fiber has the characteristics ...
