Method for extracting banana stem fiber

Abstract

The invention discloses a method for extracting stalk fiber hemp of bananas. The steps of the method for extracting the fiber hemp comprises: (1) calcium oxide is formulated into a solution of limewater with a concentration of 3%; (2) the limewater solution filters out white lime after precipitation, and surface clean water is taken out; (3) stalk glue is pressed and stripped off by using a rollshaft squeezer; (4) after being pressed and rough machined, stalk skin of the banana is put into the limewater solution, and is marinated, rubbed, dried out, carded, and eliminated impurity; (5) a solution of sodium hypochlorite with a concentration of 3% is formulated and the stalk hemp is put into the sodium hypochlorite solution to be marinated, bleached and dried out; (6) a solution of N-octadecylN'-ethylene urea with a concentration of 1% is formulated, the stalk hemp which is bleached and dried out is marinated by the solution of the N-octadecylN'-ethylene urea with a concentration of 1 percent and heated, reduced temperature into normal temperature, dried out, so as to gain the hemp of the banana. The invention not only changes waste into valuable, but also adequately makes use of resources. The equipment which the invention needs is simple so that rankandfiler also can use it easily. And the invention can extract the fiber manila hemp with light quality and wonderful hydroscopicproperty, wherein, the gained fiber and adhesion tissue can be fully made use of.

Description

technical field [0001] The invention relates to a method for mechanically separating fibers from plant raw materials, in particular to a method for extracting fiber hemp from banana stems. Background technique [0002] There are many tropical plants in the tropical and subtropical regions of our country. The development and utilization of tropical natural plant fibers, such as: sisal, coconut fiber, pineapple leaf fiber, banana stem fiber, has attracted the attention of the textile industry. These fibers are made into carpets, Home textiles such as sofa releases and wall coverings have great market potential. Pineapple leaves and banana stems are rich in fiber resources, and the fiber quality is softer and slender than sisal hemp, with good spinnability, and can also be used to make high-end clothing fabrics. In addition to the characteristics of hemp, these two fibers also have the characteristics of unique style, special luster, good thermal conductivity, cool and smooth...

Problems solved by technology

For example, in Pubei County, Guangxi, there are no less than 100,000 mu of plants. The banana stem is a hemp plant with a lot of fiber. Historically, farmers often cut off the roots immediately after cutting the banana fruit and let it rot in the field. , its stalk has not been well developed and utilized. So far, no technical report has been found to utilize the banana stalk to obtain fiber hemp. However, there is no method for extracting fiber hemp from the banana stalk that meets the production needs. Banana stems are soaked in water, and after the stems rot and deteriorate, they are fished out, and the fiber hemp is extracted by manual hammering, which has high labor intensity, low productivity, and high development costs, thereby restricting the development and utilization of large-scale resources, resulting in Banana stems can't be industrialized to get fiber hemp
