Embodiment 1

[0047] Select good banana stems in Musa plants, cut them off, and beat them mechanically to remove part of the lignin, hemicellulose and pectin to obtain fiber raw materials. Carry out component analysis to it (with reference to ramie standard GB5889-86):

[0048] Cellulose content: 63.6%

[0049] Hemicellulose content: 21.1%

[0050] Lignin content: 12.2%

[0051] Pectin content: 0.7%

[0052] Water soluble content: 2.4%.

[0053] Then it is subjected to acid pre-impregnation, water washing, alkali boiling, water washing, dehydration, fluffing and oiling treatment, which together constitute the steps of degumming.

[0054] The specific degumming steps are as follows:

[0055] 1. Acid pre-impregnation: put the banana fiber raw material obtained after mechanical knocking into a sulfuric acid solution pot with a sulfuric acid concentration of 1.5g / L, the temperature is 50°C, and the weight ratio of banana fiber to sulfuric acid solution is 1 / 15, keeping 2 hours, then carry...

Embodiment 2

[0060] Select the stems of bananas of the genus Musa, cut them off, and beat them mechanically to remove part of the lignin, hemicellulose and pectin to obtain fiber raw materials. Carry out component analysis to it (with reference to ramie standard GB5889-86):

[0061] Cellulose content: 63.6%

[0062] Hemicellulose content: 21.1%

[0063] Lignin content: 12.2%

[0064] Pectin content: 0.7%

[0065] Water soluble content: 2.4%.

[0066] Then it is subjected to acid pre-impregnation, water washing, alkali boiling, water washing, dehydration, fluffing and oiling treatment, which together constitute the steps of degumming.

[0067] The specific degumming steps are as follows:

[0068] 1. Acid pre-impregnation: Put the banana fiber raw material obtained after mechanical knocking into a sulfuric acid solution pot with a sulfuric acid concentration of 0.5g / L at a temperature of 30°C. The weight ratio of banana fiber to sulfuric acid solution is 1 / 12, keeping 1.5 hours, then c...

Embodiment 3

[0073] The stems of the selected Musa plant bananas are cut off and mechanically tapped to remove part of the lignin, hemicellulose and pectin to obtain fiber raw materials. Carry out component analysis to it (with reference to ramie standard GB5889-86):

[0074] Cellulose content: 63.6%

[0075] Hemicellulose content: 21.1%

[0076] Lignin content: 12.2%

[0077] Pectin content: 0.7%

[0078] Water soluble content: 2.4%.

[0079] Then it is subjected to acid pre-impregnation, water washing, alkali boiling, water washing, dehydration, fluffing and oiling treatment, which together constitute the steps of degumming.

[0080] The specific degumming steps are as follows:

[0081] 1. Acid pre-impregnation: Put the banana fiber raw material obtained after mechanical knocking into a sulfuric acid solution pot with a sulfuric acid concentration of 0.8g / L at a temperature of 40°C. The weight ratio of banana fiber to sulfuric acid solution is 1 / 10, keeping 1.2 hours, followed by w...

Abstract

The invention relates to a musa fiber, which is prepared from stems of musa plants, which are used as raw materials, wherein the musa fiber comprises the following components: cellulose is 81-95 percent, hemicellulose is 1.0-5.0 percent, lignin is 1.0-2.8 percent, other components are pectin water soluble matter and is based on the dry weight of the musa fiber. The above musa fiber is prepared through the mechanical treatment, acid preimpregnation, washing, soda boil, washing, dehydration and oil supply, the above musa fiber is used to be spun into 10-60 single yarn, the process has low cost, compared with ancient process, the strength and the fineness of the made fiber are improved, and the process of preparing the musa fiber of the invention is also capable of being used to made mulberry fiber. The invention opens a new way for the development and utilization of phloem resources, has an important significance at the present that a part of prior fiber resources are run out, and accords with strategic demands of sustainable development.

Description

technical field [0001] The present invention relates to a kind of plantain fiber and its preparation method and application, and said plantain is preferably plantain and banana. Background technique [0002] The fibers of plantains and bananas are stored in the bast of plantains and banana trees respectively. They belong to bast fibers and have the characteristics of general hemp fibers. For example, the fiber has high strength, low elongation, high moisture regain, good hygroscopicity, thick and hard fiber, and high initial modulus. The length of the single fiber (cell) is relatively short, only about 2.0-3.8mm, the cellulose content of the single cell is 58%-76%, and the width of the single fiber is relatively thin, about 8-20m, so plantain and banana are usually considered The single fiber is very short and cannot be directly used for spinning. It can only be spun with technical fibers, and the fibers are relatively grouped, so it is only suitable for spinning low-grade ...
