Embodiment 1

[0031] The present invention also can be realized by following method in concrete implementation:

[0032] (1), preparation of compound bacteria liquid:

[0033] Combine brown rot fungus: Acinetobacter ruckerii: Pseudomonas fluorescens: Rhinemeria tangshanus at a mass ratio of 2.2~2.8︰1.2~1.8︰1.2~1.8︰1.2~1.8, add water to form a flora Density is 6×10 7 more than one / ml compound bacteria solution;

[0034] (2), raw material washing and steaming:

[0035] Cut the hemp raw material into a length of 4-5cm, then wash it with water, enter the steaming chamber, steam and soften it for 10-30 minutes, and then enter the oblique spiral dehydrator for dehydration after the hemp raw material is softened;

[0036] (3), biodegradation:

[0037] The dehydrated hemp raw material is sent to the composite bacteria liquid warehouse, so that the composite bacterial group begins to biodegrade the lignin of the hemp raw material. The mass ratio of the dehydrated hemp raw material to the composi...

Abstract

The invention relates to a method for biologically and ultrasonically preparing textile fibers, which effectively solves the problem of pollution and the problem on how to save energy and water, reduce emission, reduce production cost and increase the utilization rate of materials. The method includes the following steps: brown-rot fungi, acinetobacter lwoffii, pseudomonas fluorescens and rheinheimera tangshanensis are mixed together and added with water, so that a compound bacteria liquid is prepared; a material is cut up, washed with water, steamed to be softened, dehydrated and added with the compound bacteria liquid for biodegradation, the material is then bailed out, drained and sterilized by steam under normal pressure, defibering agent is then added to defiber the material into fiber bundles, the fiber bundles are ultrasonically processed, so that the fiber bundles become single fibers, pulp in the form of the single fibers is sent into a pulp washer, washed, purified, then screened and filtered, so that purified single fibers are obtained, and the purified single fibers are soaked in warm water, then dried, carded and drawn, so that the fibers are further straightened into textile fibers. The method disclosed by the invention is advanced, easy to operate, high in production efficiency, energy-saving, environment-friendly, low in cost and easy to popularize and apply.

Description

technical field [0001] The invention relates to chemical industry, in particular to a method for preparing textile fibers by biological ultrasonic waves. Background technique [0002] In recent years, with the depletion of petrochemical resources, hemp fiber has been favored by consumers due to its ecological and environmental protection characteristics. Its demand is increasing year by year, and the annual growth rate of global natural fiber is 8%. The biggest feature of hemp fiber raw materials is high fiber content, long and thin fiber is conducive to interweaving, good strength, small fiber cell cavity, thick cell wall, and large wall-to-cavity ratio; It is easy to separate and make the fabric have low air permeability. [0003] Ultrasonic treatment of pulp fibers is mainly through the "cavitation effect" and "free radical activation" of ultrasonic waves. The bubbles formed during ultrasonic cavitation contain not only the vapor generated by the liquid itself, but also...
