Description
Technical field
The present invention relates to coconut palm monofilament field, especially a kind of coconut palm monofilament desugar technique.
Background technique
With the development of society, it is increasing as the palm fiber mattress demand of main material using Arenga engleri Beccari silk, but Arenga engleri Beccari material is often
Supply falls short of demand.There is also growth conditions harshnesses, the problem that the speed of growth is slow and price is high for Arenga engleri Beccari simultaneously.And coconut palm palm fibre has growth speed
Degree is fast, the high and low-cost feature of yield, is not much different in terms of physical property with Arenga engleri Beccari, but there are the polysaccharide such as fructose, starch
Class content is higher than Arenga engleri Beccari, easily occurs damaging by worms and going mouldy, and such as a large amount of sugared contents for reducing coconut palm monofilament, are the preferably substitution of Arenga engleri Beccari
Person.
About coconut palm monofilament desugar technique, a kind of method solved at present is that boiling is boiled, and this method is easy to operate, but cannot be very
The polysaccharide materials such as good fructose, the starch of removing coconut palm monofilament；Another method is the patent application No. is 201720664436.X
The dustless high temperature desugar mentioned in " a kind of novel Du Pont coconut palm palm fibre latex bed mattress ", temperature controls not this method during heating
When the problem of will lead to surface layer zoom.
In summary: the prior art has and Polysaccharide removing substance and coconut palm monofilament can not will appear lacking for surface layer zoom very well
Point.

1.3h。
In coconut palm monofilament desugar technique above-mentioned, in step b, the temperature of the acidolysis is 60 DEG C of temperature, time 1.2h.
In coconut palm monofilament desugar technique above-mentioned, in step c, the mass ratio of the water and B product is (200-250): 1；It is described
The temperature of boiling is 165-170 DEG C, time 1.4-1.6h, pressure 2.3-2.7MPa；The bearing capacity of the pressure resistant vessel
≥4MPa。
In coconut palm monofilament desugar technique above-mentioned, in step c, the temperature of the boiling is 167.5 DEG C, time 1.5h, pressure
Power is 2.5MPa.
In coconut palm monofilament desugar technique above-mentioned, in step d, vulcanizing tank air pressure is 0.3-0.35MPa, temperature when the processing
Degree is 115-125 DEG C, and the processing time is 0.8-1.2h.
In coconut palm monofilament desugar technique above-mentioned, in step d, vulcanizing tank air pressure is 0.32MPa when the processing, and temperature is
120 DEG C, the processing time is 1h.
Compared with prior art, the present invention have it is following the utility model has the advantages that
1, the present invention passes through H2SO4The pretreatment of solution, the loose coconut palm monofilament cell wall structure of energy, conducive to the row of sugar, moisture
Out, while the alkaloids in degrade a part of polysaccharide and fiber, a small amount of penetrating agent BX can increase intermolecular contacts area, shorten
Reaction time.
2, digestion process of the invention can remove the acid-base material in much starch, sugar and fiber.
3, carbonization process of the invention can increase the space between cells of coconut palm monofilament, be conducive to macromolecular sugar and water one in coconut palm monofilament
Play discharge.
4, the process of high temperature and pressure boiling of the invention and charing controls by reasonable temperature, can avoid coking occur
Phenomenon.
In summary: the present invention realizes and coconut palm monofilament is greatly lowered by low-kappa number, boiling and charing three-level desugar
Effect containing sugar, and have and will not make coconut palm monofilament surface layer zoom, reaction time short advantage.
To prove this technological effect, inventor is doing following detection to embodiment 1-3, and testing agency is Qingdao Kechuang matter
Measure detection company.
Can be seen that treated that coconut palm monofilament sugar content is extremely low by present invention process according to upper table, 0.5 hereinafter,
So the sugared content of coconut palm monofilament can be greatly reduced in the present invention.
