Embodiment Construction

[0006] According to the structural characteristics of Apocynum raw hemp itself and the characteristics of ultrasonic cavitation effect and microwave action, aiming at the problems existing in the existing degumming process, the process of the present invention first puts the original Apocynum apocynum into dilute tin dioxide nano-powder added. In the airtight container of lye, use microwave heat treatment to degrade the non-fibrous substances such as pectin, lignin and hemifiber in the raw hemp, and then wash the treated raw hemp with water and pickling, put it into the added The alkali concentration of tin dioxide nano-powder is in the cleaning solution of 1.0-2.0% (weight percent concentration), the content of nano-powder in this cleaning solution and above-mentioned dilute alkaline solution is to contain tin dioxide in every 10kg liquid Powder 0.8-1.2g. Use lower-frequency ultrasonic treatment, and then use higher-frequency ultrasonic treatment. When the ultrasonic wave act...

Abstract

The invention relates to a method for using ultrasonic wave and microwave to degelatinize apocynum, used in one additional nanometer material, wherein it is characterized in that: putting the apocynum into sealed container with diluted alkali liquid of stannic oxide nanometer powder; heating with microwave; washing with water; washing with acid, and putting it into the washing liquid whose alkali density is 1.0-2.0% with stannic oxide nanometer powder; treating with utlrasonic wave with low frequency; treating with ultrasonic wave with high frquency; washing it with acid and water, then drying. The inveniton has lower cost and high speed, without pollution.

Description

technical field [0001] The invention relates to a process for degumming apocynum, in particular to a process for degumming apocynum by adding nano-powder and using ultrasonic waves and microwaves, and belongs to the technical field of pretreatment of raw materials for textile production. Background technique [0002] For the existing Apocynum degumming process, research reports using chemical methods and heat treatment or ultrasonic degumming alone have been retrieved. The common disadvantages are complex operation, long degumming time and low degumming efficiency. Contents of the invention [0003] The purpose of the present invention is to provide a kind of technology that adds nano-powder and uses ultrasonic wave and microwave to make apocynum degumming, and it is economical and practical, with low cost, no pollution, fast speed and high operability. [0004] A kind of technology that adds nano-materials to make Apocynum degumming with ultrasonic wave and microwave, it ...
