Abstract
The invention relates to a process for degumming flax roving, in particular to a sodium chlorite-hydrogen peroxide bleaching integrated bath process of flax, and is characterized by comprising four processes of acid washing, washing, sodium chlorite-hydrogen peroxide bleaching and cleaning in sequence, wherein a sodium chlorite reagent and a hydrogen peroxide reagent are simultaneously added into the sodium chlorite-hydrogen peroxide bleaching process. According to the invention, the process is shortened, and the energy consumption is reduced.
Description
Technical field
The present invention relates to the process that a kind of flax roving comes unstuck, specifically is Asia-oxygen bleaching one bath process that grows flax.
Background technology
Linen fibre is a kind of pure natural fiber, and it is strong to have hygroscopicity, and radiate heat and ventilate property is good, and anti-mildew is mothproof, no static, and no chemical composition, and unique bacteria growing inhibiting and the characteristic that efficient obstruct ultraviolet ray penetrates are " fiber queen " by common people's good reputation.But, linen fibre exists because being form with bundle fiber; Though still have the existence of non-cellulose compositions such as a large amount of pectin, lignin through the combing in early stage; Influenced spinning efficiency, so need be before spinning to the fiber processing of coming unstuck, to improve fiber division degree; Clean fiber, and spun yarn successfully.
Traditional degumming tech is flax roving to be carried out the sodium chlorite processing earlier use hydrogen peroxide bleaching again.Because it is long to boil the time of floating, processing step is many, power consumption water consumption not only consuming time, and the while has also been reduced the rising of production efficiency and production cost.The patent No. is 200810041519.9; Disclose the boiling-off and the dyeing integration process that grow flax and produce in the Chinese patent of patent name for " flax produce boiling-off and dyeing integration process ", its step is that rove, pickling, Asia float, oxygen floats, wash, put into the Sodium Polyacrylate boiling-off, adopt efficient surface tension reducer and bleeding agent and use vital staining agent dyeing, last wet spinning spun yarn.Though foregoing invention is boiling-off and dyeing and be one, in the boiling-off process, still be divided into the Asia and float and floated for two steps with oxygen and carry out, processing step is more, and energy resource consumption is bigger.
The patent No. is 201110273595.4; Patent name is a kind of rescutched tow degumming and bleaching technology for " rescutched tow degumming and bleaching technology " the present invention is disclosed; With the rescutched tow is processing object, and in turn includes the following steps: washing → soda boiling → oxygen floats → cleans; Before the rescutched tow water-washing step, also comprise that it is principal character that the twice processing step is floated in pickling and Asia with it successively.Also be to be divided into independent two steps to accomplish the Asia and float with oxygen and float in the technique scheme, still have the defective of water consumption power consumption consuming time.
Summary of the invention
Technical problem to be solved by this invention is to overcome deficiency of the prior art and a kind of shortening operation is provided, one of energy efficient Asia-oxygen bleaching one bath process that grows flax.
The technical scheme that the present invention solves the problems of the technologies described above employing is: this flax Asia-oxygen bleaching one bath process; It is characterized in that: comprise that successively pickling, washing, inferior oxygen float, clean four processes, described inferior oxygen floats and adds sodium chlorite, hydrogen peroxide solution reagent in the process simultaneously.The present invention with the Asia float, oxygen floats simultaneously and carries out; And impurity such as the pectin on the removal flax fibre, lignin and Asia-oxygen float substep and do not have basic difference; Can reach the effect of traditional degumming tech equally; And quality index such as the yarn strength, bar evenness of spinning are equal to traditional handicraft, and the consumption of the energy is obviously reduced, and have also reduced the degree of wastewater treatment simultaneously.
Sulfuric acid solution concentration is 1.5g/L in the acid cleaning process of the present invention, and nonionic penetrant concentration is 0.5g/l, and described nonionic penetrant is that Hensel model of producing advanced in years is INVADINE LUN, and acid cleaning process carries out 30min under 40 ℃.
Washing of the present invention at every turn the time of carrying out be 10min, wash altogether twice.Can linen fibre be cleaned available energy in the time of the control water consumption.
Inferior oxygen of the present invention floats that sodium chlorite concentrations is 0.8g/L in the process; Concentration of hydrogen peroxide is 1.925g/L, and nonionic penetrant concentration is 1g/L, and sodium silicate solution concentration is 5g/L; Chelating agent 5097 concentration that the triumphant fine chemistry industry of section is produced are 1g/L; Use NaOH 1g/L and soda ash 4g/L adjustment pH value to be 9-10, handle 90min down at 90 ℃, described nonionic penetrant is that Hensel model of producing advanced in years is INVADINE LUN.
The present invention compared with prior art has the following advantages: the Asia of routine is floated to float with oxygen unite two into one; Impurity on removal flax fibre as much as possible lowers the damage to flax fibre when improving its whiteness again as far as possible, the present invention through rational control each item technological parameter to realize above-mentioned target.The processing technology that the present invention is conventional has relatively been saved manufacturing procedure, has shortened the whole bleaching process time.Simultaneously also reduce the auxiliary chemicals use amount, can alleviate the wastewater treatment difficulty.
The specific embodiment
Asia-oxygen bleaching one bath process of the present invention is primarily aimed at linen fibre, and all the other flax fibres also can be used for reference use.Whole linen thread and yarn processing procedure is: flax roving combing, flax roving Asia-oxygen one are bathed bleaching, the spinning of flax spun yarn.
Described Asia-oxygen bleaching one bath process comprises:
1, pickling: the sulfuric acid concentration of employing is: 1.5g/L, nonionic penetrant concentration is: 0.5g/l.Under 40 ℃, pickling 30min.What nonionic penetrant adopted is that Hensel model of producing advanced in years is INVADINE LUN.
2, washing: pickling finishes the back with clear water washing twice, each 10 minutes.
3, sodium chlorite concentrations is 0.8g/L; Concentration of hydrogen peroxide is 1.925g/L, and nonionic penetrant concentration is 1g/L, and sodium silicate solution concentration is 5g/L; Chelating agent 5097 concentration that the triumphant fine chemistry industry of section is produced are 1g/L; Use NaOH 1g/L and soda ash 4g/L adjustment pH value to be 9-10, handle 90min down at 90 ℃, described nonionic penetrant is that Hensel model of producing advanced in years is INVADINE LUN.
4, clean up.
Though the present invention with embodiment openly as above; But it is not in order to limit protection scope of the present invention; Any technical staff who is familiar with this technology, change and the retouching in not breaking away from design of the present invention and scope, done all should belong to protection scope of the present invention.
