Description
Technical field
The invention belongs to the manufacture field of people's hair products, be specifically related to a kind of method utilizing Crinis Carbonisatus bleaching effluent to carry out Crinis Carbonisatus desquamation process.
Background technology
In the production process of people's hair products, need to first destroy surface scale layer-stripping squama process, then destroy the natural black pigment in Crinis Carbonisatus with oxidation or reduction means, and then produce the people's hair products comprising all kinds of color and performance. But the basic ingredient of Crinis Carbonisatus scale layer is the rigid keratin protein of various natural amino acid composition, stability height, good springiness, dilatancy are little, and itself plays very important protective effect for the cortical layer within Crinis Carbonisatus and melanin. For this, first Crinis Carbonisatus is carried out stripping squama and processes (acid system desquamation) by traditional Crinis Carbonisatus product row sparetime university many employings chloro-containing reagent, so that bleaching assistant can penetrate into inside Crinis Carbonisatus, and then occurs multiple chemical reaction to be removed with melanin. But, the method is difficult to control due to the process of reaction, easily causes reaction irregular and the strength damage of Crinis Carbonisatus is bigger than normal; And substantial amounts of absorbable organohalogen compounds AOX can be generated in the course of processing, environment is worked the mischief.
In the fiber bleached process of Crinis Carbonisatus, hydrogen peroxide is the most frequently used to a class bleaching agent, and the oxidation of melanin in Crinis Carbonisatus fiber effectively can be faded and be dissolved in bleaching liquid by it. In order to realize the effect that Crinis Carbonisatus fiber is bleached preferably, hydrogen peroxide needs excessive more, contains more hydrogen peroxide composition too thus causing in waste water. This bleaching effluent general cannot carry out reclaiming use again, can only fully enter wastewater treatment equipment and process, thus causing the bigger wasting of resources.
Summary of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of method utilizing Crinis Carbonisatus bleaching effluent to carry out Crinis Carbonisatus desquamation process, it is achieved the recycling of bleaching effluent; Realize the limited damage to Crinis Carbonisatus fiber scale layer, and then improve the strength property of fiber; Technique is simple, be suitable to industrialized production.
The method utilizing Crinis Carbonisatus bleaching effluent to carry out Crinis Carbonisatus desquamation process of the present invention, first, processes Crinis Carbonisatus fiber preoxidation with Crinis Carbonisatus bleaching effluent, then uses hydrogen peroxide ferment treatment, finally use Protease Treatment.
The described method utilizing Crinis Carbonisatus bleaching effluent to carry out Crinis Carbonisatus desquamation process, comprises the following steps:
(1) pre-oxidation treatment of Crinis Carbonisatus fiber
First, controlling the mass content of hydrogen peroxide in Crinis Carbonisatus bleaching effluent is 0.5% to 4%;Place into Crinis Carbonisatus fiber to soak, soak complete taking-up Crinis Carbonisatus fiber;
(2) hydrogen peroxide ferment treatment
Adding hydrogen peroxide enzyme aqueous solution in Crinis Carbonisatus fiber after the pre-oxidation treatment that step (1) obtains to process, be disposed taking-up Crinis Carbonisatus fiber;
(3) Protease Treatment
Crinis Carbonisatus fiber after the hydrogen peroxide ferment treatment obtain step (2) is put in aqueous solution of protease and is soaked, and takes out and cleans, obtains the Crinis Carbonisatus fiber of desquamation.
Wherein,
In step (1), Crinis Carbonisatus bleaching effluent is the waste water after Crinis Carbonisatus fiber carries out hydrogen peroxide bleaching. Preferred: pH value is 7-8.5, the mass content of hydrogen peroxide is 0.05%-5%, and the mass content of potassium peroxydisulfate is 0.5%-2%, and the mass content of sodium silicate is the waste water of 0.5%-3%.
In step (1), soaking temperature is 20-40 DEG C, and soak time is 10-30min. In immersion process, pH can change with soak time, and therefore immersion process needs constantly to follow the tracks of pH change, constantly adds ammonia maintenance pH stable.
In step (2), in hydrogen peroxide enzyme aqueous solution, catalatic mass content is 0.1%-5%; Wherein, catalase is TerminoxUltra50L.
In step (3), the pH value of aqueous solution of protease is 4-8; Protease is the one in microbe-derived protease, the protease of plant origin or the protease of animal origin; The mass percent of protease and Crinis Carbonisatus fiber is 0.1%-10%.
Microbe-derived protease is one or more in actinomycetes protease, alkaline protease, serrapeptass, mold protease, aspergillus oryzae or aspergillus niger; The protease of plant origin is one or more in papain, ficin or bromelain; The protease of animal origin is one or both in trypsin or the solidifying enzyme of intestinal.
In step (3), soaking temperature is 20-60 DEG C, and soak time is 10-30min.
Bath raio respectively 1:10-1:50,1:10-1:40 and the 1:10-1:50 of step (1), step (2) and step (3).
The method utilizing Crinis Carbonisatus bleaching effluent to carry out Crinis Carbonisatus desquamation process, is suitable in vitro Crinis Carbonisatus fiber is carried out desquamation process. Crinis Carbonisatus fiber after desquamation process carries out according still further to conventional bleaching and mordant dyeing technique.
Compared with prior art, the invention have the advantages that
(1) Crinis Carbonisatus fiber is carried out pre-oxidation treatment by the hydrogenperoxide steam generator that the present invention adopts mass content to be 0.5% to 4%, and soaking temperature is 20-40 DEG C, and soak time is 10-30min. With this understanding, hydrogen peroxide can aoxidize the part disulfide bond in scale effectively, is unlikely to cause bigger fibre damage under this concentration and temperature simultaneously. By the bleaching effluent direct reuse containing undecomposed hydrogen peroxide in the desquamation operation of Crinis Carbonisatus fiber, it is achieved to the destruction of scale layer with divest, reduce energy consumption and the water consumption of whole bleaching process.
(2) with protease, Crinis Carbonisatus fiber is processed, it is possible to effectively realize the destruction that enzyme molecule is single-minded to the combination of scale layer keratin substrate and specially good effect, thus realizing the partial destruction to scale layer rather than divesting completely. The shortcoming that present invention, avoiding the tradition environmental pollution that causes of acid system desquamation technique and poor working environment, reduces the discharge of organohalogen compounds; Realize the recycling of bleaching effluent, and then reduce the water consumption in whole bleaching process; Simultaneously, it is possible to directly utilize the preheating in bleaching effluent for desquamation technique without more energy loss, it is achieved it is energy-saving and cost-reducing that enterprise produces.
(3) present invention is by the control of bleaching effluent pretreatment stage concentration of hydrogen peroxide and temperature, and the utilization of Protease Treatment technique, achieve the limited damage to Crinis Carbonisatus fiber scale layer, rather than divesting completely scale layer in classical acid metallization processes, and then improve the strength property of fiber.Through identical following bleaching technique when, the Crinis Carbonisatus fibre whiteness that the inventive method processed is adopted to reach 22-24, strength property can reach more than 129.0cN, the whiteness value of more traditional acid system desquamation technique improves more than 10%, strength property improves more than 15%, and feel is more plentiful and lubricious.
(4) present invention process is simple, effective, be easily achieved industrialized production.
