Embodiment 1

[0026] A kind of modification processing method of ramie fiber for textile products, comprises the steps:

[0027] (1) Ramie fiber pretreatment:

[0028] First put the ramie fiber and the active liquid into the high-pressure tank according to the weight-to-volume ratio of 2g:4mL, then raise the temperature in the high-pressure tank to 120°C at a speed of 3°C / s, and pump the water in the high-pressure tube at a speed of 0.02MPa / s. The pressure in the high-pressure tank was raised to 0.3MPa, and after maintaining the pressure for 40s, the pressure in the high-pressure tank was reduced to normal pressure at a rate of 0.007MPa / s, and the ramie fiber was taken out for subsequent use;

[0029] (2) Proton irradiation treatment:

[0030] Put the ramie fiber pretreated in step (1) into a low-energy proton irradiation box for irradiation treatment, and the irradiation treatment time is 3 minutes;

[0031] (3) Soaking treatment:

[0032] Immerse the ramie fibers after the proton irrad...

Abstract

The invention discloses a modified processing method for ramie fibers used for a textile article. The method comprises the following steps of: (1) preprocessing ramie fibers; (2) carrying out proton radiation processing; (3) carrying out dipping processing; (4) carrying out plasma processing; and (5) carrying out drying processing. The modified processing method disclosed by the invention carriesout modified processing on the ramie fibers by aiming at the problems of the ramie fibers, all steps are reasonably matched, the degree of crystallinity of modified ramie fibers is lowered, elongationat break and a breaking turnover number are obviously improved so as to improve the softness of the ramie fibers, the usability of the textile article is improved, and therefore, the modified processing method has good market competitiveness and a good market popularization and application value.

Description

technical field [0001] The invention belongs to the technical field of textile products processing, and in particular relates to a method for modifying ramie fibers used in textile products. Background technique [0002] Ramie is a special product of our country and is known as "Chinese grass, Chinese treasure" by the world. The moisture absorption and air permeability of ramie fiber is about 3-5 times that of cotton fiber, and it also contains beneficial elements such as eminence, pyrimidine, and purine. Best for pillowcase fabrics. Because the top of ramie fiber is sharp and itchy, it is not recognized internationally as a fabric that directly contacts the skin. In addition, ramie has the characteristics of high strength and low elongation, and the fabric is easy to wrinkle. Therefore, it is particularly important to reduce the hardness of ramie fiber, improve its softness, and relieve itching. [0003] There are a large number of hydrogen bonds in the ramie fiber, whic...
