Description
Technical field
The present invention relates to field of textiles, and in particular to a kind of extracting method of eucalyptus hide fiber.
Background technique
Eucalyptus is one of three big quick growing species of trees, adaptable, and material kind multiplicity, widely used, eucalyptus economic value is high, is
Very rare short cycle industrial cut stock tree species, general 5-8 can fell utilization.Only the application of Eucalyptus Wood is led at present
Eucalyptus barks can often be removed, cause waste, but fiber rich in eucalyptus barks, it can separate, for doing weaving material
Material, production carpet, ground cushion etc..
Summary of the invention
The purpose of the present invention is to provide a kind of extracting method of eucalyptus hide fiber, the eucalyptus hide fiber extracted uniformly,
Impurity is few, ensure that the quality of eucalyptus hide fiber.
To achieve the above object, the invention provides the following technical scheme:
A kind of extracting method of eucalyptus hide fiber, comprising the following steps:
(1) eucalyptus barks are subjected to cutting, eucalyptus barks is made to become thin slice；
(2) deionized water, pectase, lipase are added in cylinder and are heated to 45 DEG C of holding constant temperature after mixing, it will
Eucalyptus barks fragment is put into cylinder and filters after immersion 2-3h, high-temperature steam drying is then carried out at 150-180 DEG C, until eucalyptus barks
Moisture content be down to 14-16%；
(3) boron trifluoride is modulated into the alcoholic solution that concentration is 26%, then brushes eucalyptus barks thin slice after the drying
Surface, eucalyptus barks sheet surface is scrubbed after 2-4h；
(4) solution of potassium carbonate is added in cooker, the eucalyptus barks thin slice after being put into step (3) scrub carries out heating and adds
Pressure, boiling 1-2h take out after boiling and are rinsed with water 20-30min；
(5) the eucalyptus barks thin slice after rinsing step (4), which is put into opener, carries out shredding, obtains crude fibre；
(6) deionized water and chlorine dioxide, sodium carbonate are uniformly mixed, the thick fibre after step (5) are rinsed then is added
Dimension impregnates 30-40min, is rinsed 20-30min with hot water after taking-up；
(7) by step (6) rinse after crude fibre dehydrate, then using carding machine progress it is loose to get
The eucalyptus hide fiber.
Preferably, in the step (1), thin slice with a thickness of 0.5-1mm.
Preferably, in the step (2), the additive amount of lipase is the 0.5-0.7% of deionized water quality, lipase
Additive amount is the 0.8-1.2% of deionized water quality.
Preferably, in the step (4), the concentration of solution of potassium carbonate is 2.5-4.3%.
Preferably, in the step (4), heating and temperature control is between 100-124 DEG C, and pressurization pressure control is in 17.5-
18.3MPa。
Preferably, in the step (6), hot water temperature is 80-90 DEG C.
Preferably, in the step (6), the concentration of sodium carbonate is 5%, and the concentration of chlorine dioxide is 3-5%.
Preferably, in the step (7), loose method is careless first progress 1-2 times, then carries out 2-4 essence and dredge.
Compared with prior art, the beneficial effects of the present invention are:
(1) since eucalyptus barks are harder, eucalyptus barks can be softened by the pectase in step (2), then by lipase, it is real
Then now first time degreasing carries out high-temperature steam drying, high-temperature steam can reduce the boiling point of fat, effective to evaporate fat,
And moisture content is reduced, it realizes second of degreasing, realizes that third time degreasing makes finished fiber by multiple degreasing by step (3)
In Oil and Fat Content substantially reduce, improve the quality of eucalyptus hide fiber.
(2) in step (3), under the soda-dip of high temperature and pressure, the intracutaneous fat of eucalyptus is dissolved in water with potassium carbonate generation
Fatty acid potassium, secondly, polysaccharide be dissolved, hemicellulose is decomposed, and the intracutaneous hydroxyl of eucalyptus, lignin and glue are reduced
Matter.
(3) eucalyptus barks are first parsed into crude fibre, are then impregnated in the solution in step (5) again, crude fibre can be made
Softened again.
(4) eucalyptus hide fiber produced by the present invention greatly reduces Oil and Fat Content and residual gum content, secondly, fiber obtained is thick
Carefully, length is uniform, and impurity is few, can be used for making textile.
