Problems solved by technology

Therefore, the fiber made from garlic leaves has a health care function. In addition, there are only literature reports on the preparation and basic performance of garlic leaves fibers, that is, cellulase is used to impregnate garlic leaves fibers, but the degumming time of fibers is long, and the attachment of fibers There are many deposits, the length of the fiber is poor, and the strength of the fiber is not high
[0005] In addition, although there are patent documents CN101922049A report microwave irradiation combined with alkali-oxygen degumming to process hemp fibers, patent documents report adopting ultrasonic waves and expansion compound additives (expansion protein agent, cellulase, hemicellulase, pectinase, non-ionic osmotic agent) to process pineapple leaf fiber, the patent document CN103835002A reports that the combination of low-temperature plasma, pectinase and hemicellulase is used to degumming kenaf, but so far, there is no special process for processing garlic leaf fiber both at home and abroad

Embodiment 1

[0028] A preparation method of garlic sprout leaf fiber, the steps are as follows:

[0029] (1) Preprocessing:

[0030] Garlic leaves are picked, washed and dried, mechanically beaten to remove impurities, and then pretreated with compound acid. The treatment time is 10 minutes, the temperature is 50°C, and the bath ratio is 1:20. The formula of the compound acid is: citric acid 4g / L, oxalic acid 2g / L, malic acid 1g / L, tartaric acid 1g / L;

[0031] (2) Low temperature plasma treatment:

[0032] Wash the pretreated garlic leaf fiber twice, dry it, place it in the reaction chamber of the plasma generator, close the reaction chamber, evacuate it, connect it to oxygen, and turn on the radio frequency power supply after the airflow is stable, with a power of 300W. Time 3min, deflate, open the vacuum chamber, take out the garlic leaf fiber;

Abstract

The invention provides a method for preparing garlic bolt leaf fibers. The method comprises the steps of compound acid pretreatment, low-temperature plasma treatment, microwave radiation and complex enzyme alternate treatment, water washing, soap washing, dewatering, shaking to be loose, oil feeding and drying. According to the method for preparing the garlic bolt leaf fibers, fiber degumming time can be shortened, attachments on the surfaces of the garlic bolt leaf fibers can be reduced, spinnability can be improved, and the garlic bolt leaf fibers prepared through the method for preparing the garlic bolt leaf fibers have high strength and elongation at break and large length.

Description

technical field [0001] The invention belongs to the field of materials, in particular to a natural plant fiber. Background technique [0002] In recent years, with the increasing shortage of energy and resources around the world, the development and research of new plant fibers has become a hot topic of research by scholars at home and abroad. A large number of existing cellulose fibers in nature have not been developed and utilized. As a large agricultural country, my country is rich in natural fiber raw materials, and a large amount of cellulose raw materials can be processed with biomass products, providing a large amount of green cellulose raw materials for the textile industry. [0003] At present, there are many kinds of plant fibers studied by researchers at home and abroad, but most of them are in the initial stage, and there are few industrialized products. Specifically, the Institute of Process Engineering of the Chinese Academy of Sciences developed a method for ...
