Problems solved by technology

Most of these methods adopt the second cooking method, which has the disadvantage of excessive degumming, which destroys the structure of the mulberry fiber, has more short fibers, makes the fiber surface rough, has poor spinnability, low production rate, and has a long process flow and relatively complicated operation. It will also cause serious pollution to the environment, which is not in line with the concept of harmonious development of ecological environmental protection in modern society, thus limiting its industrialization

Embodiment 1

[0027] The mulberry bark is preliminarily removed from impurities, tied into a cage, and then soaked in a sulfuric acid solution with a bath ratio of 1:10, where the concentration of sulfuric acid is 3g / L, treated at room temperature for 30min, and then heated at 1°C / min Treat at 40°C for 30 minutes, then heat at 1°C / min to 60°C, and then treat for 60 minutes; wash with water until neutral. Then put it into the alkali-oxygen treatment solution, wherein the concentration of hydrogen peroxide is 30% hydrogen peroxide 40g / L, sodium borohydride 3g / L, sodium pyrophosphate 1g / L, the temperature is raised to 70°C at 1°C / min, and the treatment time is 45min. After the completion, proceed to supercritical carbon dioxide fluid degumming treatment, put the mulberry fiber into the supercritical fluid treatment device, first treat it at a pressure of 18MPa and a temperature of 110°C for 10 minutes, and then treat it at a pressure of 12MPa and a temperature of 100°C for 10 minutes , and th...

Embodiment 2

[0030] The mulberry bark is preliminarily removed from impurities, tied into a cage, and then soaked in a sulfuric acid solution with a bath ratio of 1:10, where the concentration of sulfuric acid is 5g / L, treated at room temperature for 20min, and then heated at 1°C / min Treat at 40°C for 30 minutes, then heat at 1°C / min to 60°C, and then treat for 60 minutes; wash with water until neutral. Then put it into the alkali-oxygen treatment solution, in which the hydrogen peroxide concentration is 30% hydrogen peroxide 60g / L, sodium borohydride 2g / L, sodium pyrophosphate 2g / L, 1°C / min heating temperature is 75°C, treatment time is 45min . After the completion, proceed to supercritical carbon dioxide fluid degumming treatment, put the mulberry fiber into the supercritical fluid treatment device, first treat it at a pressure of 18MPa and a temperature of 120°C for 10 minutes, and then treat it at a pressure of 12MPa and a temperature of 120°C 10min, and then under the condition of pr...

Embodiment 3

[0033] The mulberry bark is preliminarily removed from impurities, tied into a cage, and then soaked in a sulfuric acid solution with a bath ratio of 1:15, where the concentration of sulfuric acid is 5g / L, treated at room temperature for 30min, and then heated at 1°C / min Treat at 40°C for 30 minutes, then heat at 1°C / min to 60°C, and then treat for 60 minutes; wash with water until neutral. Then put it into the alkali-oxygen treatment solution, wherein the concentration of hydrogen peroxide is 30% hydrogen peroxide 50g / L, sodium borohydride 25g / L, sodium pyrophosphate 1g / L, the temperature is raised to 60°C at 1°C / min, and the treatment time is 45min. After the completion, proceed to supercritical carbon dioxide fluid degumming treatment, put the mulberry fiber into a supercritical fluid treatment device, first treat it at a pressure of 18MPa and a temperature of 100°C for 10 minutes, and then treat it at a pressure of 12MPa and a temperature of 100°C 10min, and then under th...

Abstract

The invention discloses a preparing method for mulberry fibers. The preparing method includes the steps of impurity removing, bundling, cage loading, chemical preprocessing, supercritical carbon dioxide fluid degumming processing, bio-enzyme degumming processing, washing, dewatering, oil feeding, carding and drying, wherein the chemical preprocessing method includes the steps of pickling processing and alkali-oxygen processing. The mulberry fibers obtained with the preparing method are high in degumming rate, small in damage and high in performance, and meet the modern environment-friendly requirement.

Description

[0001] This application is 2014103088476, and the application date is 2014-06-30. The invention name of the invention patent application named "a mulberry fiber preparation method" is invented. Technical field [0002] The present invention belongs to the field of making fiber fiber. Background technique [0003] my country is a large nation, with an area of ​​8 million acres in the country, and the output of mulberry fibers can reach 800,000 tons per year.The research and development of natural mulberry fiber for textile materials can not only comprehensively use the domestic waste bark resources to achieve waste utilization; at the same time, it can increase farmers' income and have greater social and economic benefits. [0004] Mulberry skin contains a variety of fibers. Among them, the ingredients such as lipids, semi -cellulose, and lignin are similar to some tough skin fibers, while the content of fruit glue is much higher than that of other tough fibers.It can be seen that ...
