4 2--2M+ alkyl phosphate salt compound, materials such as other filament expansion agent, chelated dispersants are common used material.
After decatize oxygen bleaching liquor modulates, grey cloth by being placed in the decatize oxygen bleaching liquor, and is padded grey cloth by milling train, the temperature of grey cloth is controlled between 55～65 ℃ when padding, and is preferably 60 ℃.Treat to place it in after grey cloth pads well and carry out decatize in the steam box, the temperature of decatize is controlled at 60～105 ℃, and the time of decatize is 30～90 minutes, with clear water grey cloth is washed after decatize is finished, and can carry out follow-up dyeing, stamp step then.
Such scheme should note following some:
(1) influence of concentration: when bleaching liquor endoperoxides hydrogen concentration reaches 5g/L, can reach the bleaching requirement, concentration increases again, and whiteness does not improve thereupon, causes cotton fiber tendering on the contrary.Thin fabric can also suitably reduce concentration of hydrogen peroxide in the bleaching liquor
(2) Temperature Influence: the decomposition rate of hydrogen peroxide raises with temperature to be increased, and therefore the way of available elevated temperature shortens bleaching time, and generally in the time of 100～105 ℃, the hydrogen peroxide decomposes rate can reach 90%, and whiteness is also best.Adopt short flow process steam method oxygen to float and to save time, and casing is sealed.Can improve the whiteness effect
(3) influence of pH value: hydrogen peroxide is more stable in acid bath, industrial hydrogen peroxide concentrated solution content about 27%～35%, the hydrogen peroxide decomposes rate increases with the pH value of solution value in alkaline bath, in bleaching liquor, add stabilizing agent, can reduce the decomposition rate of hydrogen peroxide, the pH value all has discoloration between 3～13.5, but the pH value is 10～11 o'clock, fabric whiteness can reach optimum level, also mostly bleaching liquor pH value is adjusted to about 10 in the actual production
The influence and the stabilizer function of metal ion when (4) bleaching: molysite, mantoquita and iron filings, copper scale and dust etc. in the water, hydrogen peroxide all there is catalyticing decomposition action, making hydrogen peroxide decomposes is water and oxygen, thereby loses discoloration.Oxygen is penetrated into fabric, will make the cellulose fibre severely degrade under the high-temperature alkaline condition when bleaching, produces broken hole on the fabric of being everlasting.For preventing above-mentioned defect, can in bleaching liquor, add an amount of stabilizing agent and water quality chelated dispersants, the decomposition rate with standard of increasing water quality and reduction hydrogen peroxide produces broken hole and scratch on the prevention fabric.
