Abstract
The invention discloses a pretreatment method for cotton fabric with enzyme and hydrogen peroxide in one bath. The method comprises the steps of preparing to-be-boiled and bleached cotton grey cloth, padding in an enzyme and hydrogen peroxide working solution, steaming, rinsing with four grids of hot water rinsing, rinsing with two grids of hot water and drying. Compared with the traditional process of desizing, boiling and oxygen bleaching, the method provided by the invention has the advantages that steam consumption is saved for two thirds and pollution discharge is decreased by two thirds; caustic soda is not used and the pH value of the discharged industrial wastewater is 9-9.5; and the conversion ingredients for removing impurities and pollutants and refining are gluconic acid and ammonia, which facilitates biochemical treatment.
Description
Technical field
The invention belongs to the dyeing and finishing process field of fabric panel, the enzyme oxygen one that is specifically related to a kind of pure cotton fabric is bathed pre-treating method.
Background technology
Enzyme oxygen single bath process pre-treatment process is meant and utilizes biology enzyme under the effect of hydrogen peroxide solution; The pre-treatment process of the destarch of disposable solution COTTON FABRIC, boiling-off, bleaching; It has shortened the pre-treatment process flow process greatly, gives prominence to and has embodied energy-saving and emission-reduction, has improved product quality again; Lay a good foundation for the fast development of enterprise, greatly promoted core competence of enterprises.
Summary of the invention
The object of the present invention is to provide a kind of enzyme oxygen one of pure cotton fabric to bathe pre-treating method, the present invention compares with traditional destarch → boiling-off → oxygen bleaching process, and steam consumption has saved 2/3rds, and blowdown has reduced 2/3rds; Do not use caustic soda, the pH value of the industrial wastewater of discharging is 9～9.5, and the conversion composition of impurity removing refining decontamination is glucose acids and Ammonia composition, helps biochemical treatment.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of enzyme oxygen one of pure cotton fabric is bathed pre-treating method, may further comprise the steps:
(1) cotton textiles are waited to boil and are floated grey cloth;
(2) pad enzyme oxygen working solution: normal temperature pads 7-10 second;
(3) 102 ℃ of decatizes 60 minutes;
(4) 90 ℃ of four lattice hot water wash;
(5) 80～85 ℃ of two lattice hot water wash;
(6) oven dry.
The set of dispense of the described enzyme oxygen of step (2) working solution is than being refining enzyme 35～40g, H
2O
210～12g, iron ion chelated dispersants 4g, bleeding agent 8g/L.
Beneficial effect of the present invention: the present invention compares with traditional destarch → boiling-off → oxygen bleaching process, and steam consumption has saved 2/3rds, and blowdown has reduced 2/3rds; Do not use caustic soda, the pH value of the industrial wastewater of discharging is 9～9.5, and the conversion composition of impurity removing refining decontamination is glucose acids and Ammonia composition, helps biochemical treatment.
