Abstract
What the present invention relates to is a kind of method that old cotton transforms regeneration, old cotton first passes through by acid complex enzyme and surfactant and soaks post rinse without the acid soak that base acid is formulated by the method, again through being soaked by alkaline complex enzyme and surfactant and the formulated alkaline soak of caustic soda, finally by kiering, washing, Chlorinated Bleaching, dechlorination, pickling, dry.The method of the biological degumming that the present invention adopts, than chemical Degumming process using water wisely 30%, reduce the consumption of water resource, and in waste discharge, soda acid content reduces greatly, environmental pollution is little reduces processing cost simultaneously, and the cotton after process is compared than chemical Degumming method, has fiber good, resilient beam, fiber index is high, impurity is few, white point is few, and soft color and luster is good, whiteness advantages of higher.
Description
(1) technical field
What the present invention relates to is a kind of method that old cotton transforms regeneration.
(2) background technology
Present old cotton regenerated utilization adopts the method for chemical Degumming usually, and this processing method water loss is large, and processing cost is high, and in waste discharge, soda acid content is high, big for environment pollution.Process the cotton quality obtained not high, such as, have the shortcomings such as fiber index is low, elastic force difference, impurity are many, white point is many.
(3) summary of the invention
The object of the present invention is to provide that a kind of processing cost is low, environmental pollution is little, the method for old cotton transformation regeneration that cotton quality after process is excellent.
The present invention is achieved in that
The method comprises the following steps:
A first by old cotton through soaking post rinse by acid complex enzyme and surfactant and the formulated acid soak of inorganic acid;
B is again through being soaked by alkaline complex enzyme and surfactant and the formulated alkaline soak of caustic soda;
C finally by kiering, washing, Chlorinated Bleaching, dechlorination, pickling, dry.
In said method: in step A, acid complex enzyme comprises acid defatting enzyme and bleaching enzymes, surfactant is bactericide, calculate by process one ton of cotton, acid defatting enzyme and bleaching enzymes consumption are respectively 0.2-0.8kg, 0.1-0.5kg, and bactericide consumption is 4-8kg, adding inorganic acid makes the pH value of acid soak be 3-6, and the bath raio of cotton and acid soak is 1: 10.
In said method: in step B, alkalescence complex enzyme comprises ligninase, degummase, hemicellulase, surfactant comprises bleeding agent, degumming agent, detergent, calculate by process one ton of cotton, the consumption of ligninase, degummase, hemicellulase is respectively 0.2-0.5kg, 0.2-0.6kg, 0.1-0.3kg, the consumption of bleeding agent, degumming agent, detergent is respectively 3-6kg, 4-9kg, 6-9kg, the bath raio of cotton and alkaline soak is 1: 10, and the consumption of caustic soda uses 10-50 gram for each rises alkaline soak.
In said method: the immersion treatment in step A is soaked at normal temperatures 18-24 hour or at 30 DEG C of-60 DEG C of temperature, soaks 1-3 hour.
In said method: the immersion treatment in step B to be soaked at normal temperatures 24-48 hour or at 100 DEG C of-150 DEG C of temperature, boiling 1-4 hour.
In said method: surfactant can also have disinfectant, calculate by process one ton of cotton, the consumption of disinfectant is 4-8kg.
In said method: surfactant can also have decolorizer, calculate by process one ton of cotton, the consumption of decolorizer is 2-4kg.
In the inventive method, enzyme has normal temperature, middle temperature, high temperature equitemperature attribute, and the immersion treatment in step A and step B selects soak at room temperature or thermophilic digestion according to the temperature property of enzyme; Chlorinated Bleaching adopts connection and Chlorinated Bleaching machine, the process of rinsing one continuous line.
The present invention all can use mechanization production in process of production, such as, adopt and draw loose machine, potcher, Chlorinated Bleaching special equipment, the various machineries such as special row crane, dedicated drying machine, drier, opener, baling press.
The inventive method can be used for new and old cotton, and white, the medical absorbent cotton of slurry made by cotton linter, various string, bast-fibre.
Beneficial effect:
1, the method for the biological degumming of the present invention's employing, than chemical Degumming process using water wisely 30%, reduce the consumption of water resource, and in waste discharge, soda acid content reduces greatly, and environmental pollution is little reduces processing cost simultaneously.
2, the cotton after biological degumming process is compared than chemical Degumming method, and have fiber good, resilient beam, fiber index is high, and impurity is few, white point is few, and soft color and luster is good, whiteness advantages of higher.
