Embodiment Construction

[0027] The invention discloses a process for preparing Abutilon fiber. The method utilizes low-frequency ultrasonic waves to assist microorganisms in degumming Abutilon. Ultrasound irradiation at a lower frequency can effectively increase the activity of microorganisms, accelerate the reproduction of microorganisms, accelerate the production of enzymes, and at the same time increase the activity of enzymes, and promote the rapid decomposition of the gum of Abutilon. In the method, an ultrasonic probe is used to apply ultrasonic waves to the reaction solution of microbial degumming, the method of microbial degumming is improved, the process of microbial degumming is greatly shortened, the degumming efficiency is improved, and high-quality velvetleum fibers can be prepared at the same time.

[0028] Among the present invention, the technological process of ultrasonic-assisted microbial Abutilon degumming is as follows:

[0029] Abutilon bast→lower frequency ultrasonic-assisted m...

Abstract

The invention provides a preparation process for a piemarker fiber. The process utilizes low-frequency ultrasonic waves to assist microbes in degumming of the piemarker fiber. On the one hand, low-frequency ultrasonic waves can effectively improve activity of the microbes, enable the enzyme production speed of the microbes to be accelerated, effectively improve activity of enzyme under specific conditions and allow gum of piemarker to be more thoroughly decomposed; on the other hand, cavitation of the low-frequency ultrasonic waves enables non-thoroughly disengaged gum to be separated from the fiber; and finally, high-frequency ultrasonic waves are used to remove residual gum in tiny parts like micropores and slits. The process overcomes the problems of a great amount of residual gum, roughness of a fiber surface and the like of conventional degumming with a single microbe, improves the quality of the fiber and enables the fiber to meet requirements of post-processing like weaving and printing and dyeing.

Description

technical field [0001] The invention relates to the technical field of hemp degumming, in particular to a process for preparing velvet hemp fibers. Background technique [0002] Abutilon, also known as green hemp, has a long history of cultivation and utilization in China. Abutilon fiber is water-resistant and not easy to corrode. As a new type of natural textile raw material, hemp fiber has the advantages of fast moisture absorption and moisture dissipation, good air permeability, natural texture, soft color and unique style. The fibers of Abutilon are located in the bast tissue of Abutilus and distributed in bundles. The single fibers are thin and short, about 1.5-6mm in length and 5-37μm in diameter. Abutilon bast must be degummed to remove non-cellulosic substances such as pectin, hemicellulose and lignin in order to obtain spinnable fibers. Therefore, degumming is an important link in the production of Abutilon hemp fiber, and the quality of degumming directly affects...
