Problems solved by technology

[0003] Due to the characteristics of high hemicellulose and lignin content, low cellulose crystallinity, and low fiber strength, it is difficult to achieve satisfactory results in the degumming of banana stem fibers by completely referring to the traditional hemp degumming process parameters. The production rate is low, the energy consumption of production is high, the consumption of lye is large, and the pollution is large

Embodiment 1

[0016] A method for producing banana stalk fiber refined hemp, comprising the following steps:

[0017] (1) Scraping: cut the banana stalks into flakes, feed them into the stalk machine, pull out when the length of the stalk is about half of the length, hold the fiber end, and feed the other section of the stalk to complete the whole scraping Hemp process to get banana stalk fiber;

[0018] (2) cage: get step (1) banana stalk fiber total amount is 500kg, carry out cage, wherein the weight of every banana stalk fiber is 0.5kg;

[0019] (3) Foaming enzyme: first prepare the degumming enzyme solution: take 400ml of pectinase solution and 40ml of xylanase solution (i.e. the volume ratio is 10:1) and mix and prepare to obtain the degumming enzyme solution; add 10 tons to the cooking pot Hot water, adjust the water temperature to 55°C, pH to 7.0; into the hot water in the boiling pot, add 35g of degumming aid magnesium sulfate, 350ml of degumming enzyme solution (that is, add 0.7ml...

[0026] (2) cage: get step (1) banana stalk fiber total amount is 650kg, carry out cage, wherein the weight of every banana stalk fiber is 1kg;

[0027] (3) Foaming enzyme: first prepare the degumming enzyme solution: take 1050ml of pectinase solution and 70ml of xylanase solution (i.e., the volume ratio is 15:1) and mix and prepare to obtain the degumming enzyme solution; add 10 tons to the cooking pot Hot water, adjust the water temperature to 60 ℃, pH to 8.0; to the hot water in the boiling pot, add 244g of degumming aid magnesium sulfate, 975ml of degumming enzyme solution (that is, add 1.5ml ...

Embodiment 3

[0032] A method for producing banana stalk fiber refined hemp, comprising the following steps:

[0033] (1) Scraping: cut the banana stalks into flakes, feed them into the stalk machine, pull out when the length of the stalk is about half of the length, hold the fiber end, and feed the other section of the stalk to complete the whole scraping Hemp process to get banana stalk fiber;

[0034] (2) cage: get step (1) banana stalk fiber total amount is 600kg, carry out cage, wherein the weight of every banana stalk fiber is 0.8kg;

[0035] (3) Foaming enzyme: first prepare the degumming enzyme solution: take 600ml of pectinase solution and 50ml of xylanase solution (that is, the volume ratio is 12:1) and mix and prepare to obtain the degumming enzyme solution; add 10 tons to the cooking pot Hot water, adjust the water temperature to 58°C, and pH to 7.5; add 90g of degumming aid magnesium sulfate and 600ml of degumming enzyme solution to the hot water in the boiling pot (that is, a...

Abstract

The invention discloses a production method of banana stem fiber refined-dry ramie .The production method comprises the following steps that firstly, fiber extraction is conducted on banana stems to obtain banana stem fibers; then, the banana stem fibers undergo caging, soaking with enzyme, cleaning and oil adding, and finally dehydration and drying are performed to obtain the banana stem fiber refined-dry ramie; in the step of the soaking with enzyme, 0.7-1.5 ml of degumming enzyme liquid is added to per kilogram of the banana stem fibers, and the degumming enzyme liquid is prepared by mixing pectinase liquid and xylanase liquid by the volume ratio of 10:1 to 15:1 .The degumming temperature is reduced, the using amount of alkali liquor is decreased, and the strength and yield of the banana stem fiber refined-dry ramie are remarkably improved by using the self-prepared degumming enzyme .In addition, the production costs of the banana stem fiber refined-dry ramie is reduced, environmental pollution is reduced, and the production method has the advantages of saving energy and protecting the environment, and has a good application prospect and greater economic value and social benefits .

Description

technical field [0001] The invention relates to the field of utilization of natural plant fibers, in particular to a production method of banana stalk fiber fine-dried hemp. Background technique [0002] The banana industry is one of the pillar industries of tropical agriculture in my country, and it is an important economic crop for farmers in tropical regions of my country to increase their income. Banana stalks and other wastes are produced after the banana fruit is harvested. A considerable amount of banana fiber can be extracted from banana stalks. Each banana tree can produce 200-500g of banana fiber. In my country, more than 100,000 tons of banana stalk fiber can be extracted. Banana stem fiber has many advantages such as fast moisture absorption and moisture release, and has great application prospects in the textile industry. Like other natural plant cellulose fibers, the main components of banana fiber are cellulose, hemicellulose, lignin, lipid wax and pectin, e...
