Banana bast fiber and preparation method thereof

Abstract

The invention discloses a method for preparing a banana bast fiber by adopting biological degumming, which is characterized by comprising the following steps of: preprocessing, inoculating, fermenting, inactivating, stamping and postprocessing. The prepared banana bast fiber has soft and loose appearance and uniform color and has no taste or obvious flaws; the fiber length is 80mm-200mm, the fiber count is 300Nm-500Nm, the breaking strength of fiber bundles is 3.5g / D-5.0g / D, and the residual gum content is 1.5 percent-3.2 percent. The biologically degummed banana bast fiber effectively removes the non-spinnable components of colloid, lignin, hemicellulose and the like and keeps the bacteria proofing, rapid moisture absorption and release of the self characteristics of the fiber, thereby ensuring the strength of the fiber; meanwhile, the banana fiber is kneaded and rolled by sterilization and machines before degumming, thereby ensuring the degumming effect and the smooth going of degumming and enabling the degummed fiber to be beneficial to the production and production development of the next working procedure.

Description

Technical field: [0001] The invention relates to a manufacturing method of bast fiber, in particular to a banana bast fiber and a manufacturing method thereof, in particular to a biological degumming method of the banana bast fiber. Background technique: [0002] In the medical field, bananas are believed to contain a large amount of protein, fat, pectin, 5-hydroxytryptamine, norepinephrine, dihydroxyphenylacetic acid and various enzymes and other substances. At the same time, it is also rich in potassium. According to the detection of scientists, per 100 grams of banana pulp, the potassium content is as high as 472 mg, which is the crown of fruit. Regular consumption of bananas can suppress and prevent cancer. Therefore, bananas are known as "fruit of happiness" and "fruit of wisdom". Because bananas have such superior functions, they are deeply loved by people. In Guangdong, Guangxi, Fujian, Taiwan, Yunnan, Hainan, Chaozhou and other regions in southern China, a large n...

Problems solved by technology

However, with the traditional chemical degumming process, most of the banana fibers are dissolved, and the fiber strength is reduced, the subsequent process cannot be produced, and it will cause environmental pollution.
