Abstract
The present invention discloses a kind of preparation method of three roads floss natural color pulp, and the method comprises the steps：（1）It is compacted after three road floss remove impurity；（2）Tri- road flosss of compacting Hou are sent into double-screw pulp-milling and carry out rubbing mill sub-wire with the hands, and tri- road floss OD wt. basis of Bing An add the anthraquinone of 2.5 3% KOH and 0.5%, control double-screw pulp-milling outlet temperature for 120 125 DEG C；（3）The slurry obtained after rubbing mill sub-wire with the hands sends into reaction warehouse, reacts 65 70min, then scrubbed, obtains three road floss natural color pulps.The inventive method process is simple, energy consumption are low, and equipment investment is few, and, up to 90-92%, the ratio of middle section water BODcr/CODcr is higher for pulping yield, are very suitable for biological treatment, and the Shuifu County after process contains potassium, is good farmland irrigating water.
Description
Technical field
The present invention relates to a kind of preparation method of three roads floss natural color pulp.
Background technology
China abounds with Cotton Gossypii, cotton linter resource very abundant.Semen Gossypii after embossing is such as all shelled floss, gained short flannel can phase
When 15-the 20% of surface total output.By stripping floss order, cotton linter can be divided into slubbing floss, two road flosss, three road flosss, and three road flosss（Again
Claim Group III cotton linter, be the cotton linter that three road delinters are peeled）The 30% or so of total cashmere output rate are accounted for, is a very important fibre
The plain resource of dimension.As three road Down Fiber length are typically in below 3mm, current tri- road flosss of domestic production corporate boss Yao Ba are brought and are glued
Glue fiber.Using three road floss of traditional soda system natural color pulp when, greatly up to 20% or so, digester yield is also only 22% left for alkali charge
The right side, environmental pollution are very serious.
The content of the invention
The technical problem to be solved in the present invention is to overcome existing defect, there is provided a kind of preparation side of three roads floss natural color pulp
Method.
In order to solve above-mentioned technical problem, the invention provides following technical scheme：
A kind of preparation method of three roads floss natural color pulp, comprises the steps：
（1）It is compacted after three road floss remove impurity；
（2）Three road flosss of compacting are sent into double-screw pulp-milling and carry out rubbing mill sub-wire with the hands, and tri- road floss OD wt. basis of Bing An are added
The KOH of 2.5-3% and 0.5% anthraquinone, control double-screw pulp-milling outlet temperature for 120-125 DEG C；
（3）The slurry obtained after rubbing mill sub-wire with the hands sends into reaction warehouse, reacts 65-70min, then scrubbed, obtains three road floss sheets
Mill base.
The inventive method has the advantages that：
（1）Process is simple, energy consumption are low, and equipment investment is few.
（2）Pulping yield, up to 90-92%, is four times of traditional slurrying.
（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, the Shuifu County after process contain potassium, are good farmland irrigating waters.
Specific embodiment
Hereinafter the preferred embodiments of the present invention are illustrated, 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）Three commercially available road flosss are opened into bag, after removing dust, remove impurity, is compacted with fiber compactor.
（2）Three road flosss of compacting are sent into double-screw pulp-milling carries out rubbing mill sub-wire with the hands, and based on three road floss of over dry per ton, plus
Enter the KOH of 2.5-3% and 0.5% anthraquinone, double-screw pulp-milling outlet temperature is controlled for 120-125 DEG C.
（3）The slurry obtained after rubbing mill sub-wire with the hands sends into reaction warehouse, stops reaction 65-70min in reaction warehouse, further to remove
Wax grease removal, obtains unscreened stock.
（4）Unscreened stock first, after the something lost Chi Zhongjing that disappears disappears something lost, is delivered to press master and is washed, obtain three road floss natural color pulps.
Finally it should be noted that：The preferred embodiments of the present invention are the foregoing is only, the present invention is not limited to,
Although being described in detail to the present invention with reference to the foregoing embodiments, for a person skilled in the art, which still may be used
To modify to the technical scheme described in foregoing embodiments, or equivalent is carried out to which part technical characteristic.
All any modification, equivalent substitution and improvements within the spirit and principles in the present invention, made etc., should be included in the present invention's
Within protection domain.
