Abstract
The method that the present invention discloses the bleaching of three suede oxygen methods, includes the following steps：（1）It is compacted after the removal of impurities of three suedes；（2）Three suedes of compacting are sent into double-screw pulp-milling and carry out rubbing mill sub-wire with the hands, and based on over dry material weight, add the anthraquinone of 3.5 4% KOH and 0.5%, and it is 120 125 DEG C to control double-screw pulp-milling outlet temperature；（3）Rub the obtained slurry of mill sub-wire with the hands and be sent into reaction warehouse, in the case where temperature is 95 100 DEG C, lead to oxygen 2 it is small when after, washing, obtains three suede bleached pulps.The method of the present invention technique is simple, and energy consumption is low, and pulp brightness is up to 82 83 IS0, for pulp yield up to 90-92%, the ratio of middle section water BODcr/CODcr is higher, disposable.
Description
Technical field
The present invention relates to a kind of method of three suede oxygen method bleaching.
Background technology
China abounds with cotton, cotton linter resource very abundant.The cottonseed after embossing is all such as shelled into suede, gained short flannel can phase
When 15-the 20% of surface total output.By stripping suede order, cotton linter can be divided into slubbing suede, two suedes, three suedes, and three suedes（Again
Claim Group III cotton linter, be the cotton linter that three delinters peel）30% or so of total cashmere output rate is accounted for, is a very important fibre
The plain resource of dimension.Using three suede of traditional soda system natural color pulp when, greatly up to 20% or so, digester yield also only has 22% left alkali charge
The right side, environmental pollution are very serious.Generally bleached during bleaching using chlorine method, it is of high cost, and it be easy to cause water pollution.
The content of the invention
The technical problem to be solved in the present invention is overcome the defects of existing, there is provided a kind of side of three suede oxygen method bleaching
Method.
In order to solve the above technical problem, the present invention provides following technical solution：
The method of three suede oxygen methods bleaching, includes the following steps：
（1）It is compacted after the removal of impurities of three suedes；
（2）Three suedes of compacting are sent into double-screw pulp-milling and carry out rubbing mill sub-wire with the hands, and based on over dry material weight, add 3.5-
4% KOH and 0.5% anthraquinone, it is 120-125 DEG C to control double-screw pulp-milling outlet temperature；
（3）Rub the obtained slurry of mill sub-wire with the hands and be sent into reaction warehouse, in the case where temperature is 95-100 DEG C, lead to oxygen 2 it is small when after, washing,
Obtain three suede bleached pulps.
The method of the present invention has the advantages that：
（1）Technique is simple, and energy consumption is low, and cost is low, and equipment investment is few, and bleaching pulp brightness is up to 82-83 IS0。
（2）Pulping yield is four times of traditional slurrying up to 90-92%.
（3）Lignin dissolution is few, and CODcr contents are considerably less, and water process is easy.
（4）The ratio of middle section water BODcr/ CODcr is higher, can reach 0.45 or so, easily biochemical, is very suitable for biological place
Reason, Shuifu County after processing contains potassium, is good farmland irrigating water.
Embodiment
The preferred embodiment of the present invention is illustrated below, it will be appreciated that preferred embodiment described herein is only used
In the description and interpretation present invention, it is not intended to limit the present invention.
Embodiment 1
（1）Commercially available three suede is opened into bag, after dedusting, removal of impurities, is compacted with fiber compactor.
（2）Three suedes of compacting are sent into double-screw pulp-milling to carry out rubbing mill sub-wire with the hands, and based on three suede material of over dry per ton,
The anthraquinone of the KOH and 0.5% of 3.5-4% is added, it is 120-125 DEG C to control double-screw pulp-milling outlet temperature.
（3）Rub the slurry obtained after mill sub-wire with the hands and be sent into reaction warehouse, in the case where temperature is 95-100 DEG C, be continually fed into industrial oxygen
（Gas tank pressure is 5 kilograms of pressure）2 it is small when after, slurry be sent into press master washing, obtain three suede bleached pulps.
Finally it should be noted that：The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention,
Although the present invention is described in detail with reference to the foregoing embodiments, for those skilled in the art, it still may be used
To modify to the technical solution described in foregoing embodiments, or equivalent substitution is carried out to which part technical characteristic.
Within the spirit and principles of the invention, any modification, equivalent replacement, improvement and so on, should be included in the present invention's
Within protection domain.
