Abstract

The invention discloses an extraction method of eucalyptus bark fibers. The extraction method comprises the following steps: cutting eucalyptus barks; adding deionized water, pectinase and lipase intoa cylinder, heating the mixture to 45 DEG C, putting the crushed eucalyptus barks in the cylinder to be soaked and filtered, and then drying the eucalyptus barks with steam at a high temperature; blending boron trifluoride into a 26% alcohol solution, brushing the surfaces of dried eucalyptus thin barks with the solution, and brushing the eucalyptus barks; adding a potassium carbonate solution into a cooking pot, putting the brushed eucalyptus thin barks to be heated and pressurized, and washing the barks with water; putting the washed eucalyptus thin barks in an opener to be opened; mixing deionized water, chlorine dioxide and sodium carbonate uniformly, then adding the washed coarse fibers, soaking the mixture and washing the mixture; dehydrating and drying the washed coarse fibers andloosening the fibers by a carding machine to obtain the eucalyptus bark fibers. The eucalyptus bark fibers extracted by the extraction method are uniform in fiber and few in impurity and the quality of the eucalyptus bark fibers is ensured.

Description

technical field [0001] The invention relates to the textile field, in particular to a method for extracting eucalyptus bark fibers. Background technique [0002] Eucalyptus is one of the three fast-growing tree species. It has strong adaptability, various wood species, and wide uses. Eucalyptus has high economic value. At present, only eucalyptus wood is used, and the eucalyptus bark is usually peeled off, resulting in waste, but eucalyptus bark is rich in fibers, which can be separated and used to make textile materials, carpets, floor mats, etc. Contents of the invention [0003] The object of the present invention is to provide a kind of extraction method of eucalyptus bark fiber, the eucalyptus bark fiber of its extraction is uniform, impurity is few, has guaranteed the quality of eucalyptus bark fiber. [0004] To achieve the above object, the present invention provides the following technical solutions: [0005] A method for extracting eucalyptus bark fiber, compri...
