Biotechnology Co., Ltd. Guangzhou Long Li washing process common washing method to introduce the next Cowboys after treatment - rinsing (BLEACH WASH) for the clothes have white or bright look and soft feel, the need to rinse the clothes, that is Ordinary washing over water, heated to 60 ° C, according to bleach the color depth, add bleach (bleaching agent), within 7-10 minutes to make the color of the board unanimously. Operation, plus bleaching agent should be shifted in the direction consistent with the transfer cylinder, in order to avoid dilution of bleach and water because they can not fall directly on the clothes as soon as possible, partial bleaching. Before bleaching, cylinder slightly higher level, in order to dilute bleach water. Bleached laundry on the rear plate, i.e. a large (small) soda (Na2CO3, NaHCO3) to water in the residual water and bleach, bleach completely stopped. After over water, add the water temperature at 50 ° C in detergent, fluorescent brighteners cellulase textile, hydrogen peroxide and other for the final wash, medium and PH, fluorescent whitening, etc., and finally softening can be. Rinsing can be divided into oxygen bleach and chlorine bleach. Oxygen bleach is the use of hydrogen peroxide oxidation under certain PH value and temperature to destroy the dye structure, so as to achieve efficient cellulase fade, the purpose of whitening, general drift slightly reddish cloth. Chlorine bleach is the use of sodium hypochlorite oxidation to destroy the dye structure, so as to achieve the purpose of fading. Chlorine bleach fade effect rough, and more for indigo denim rinse. Bleaching of the rear panel, should Hyperion residual chlorine in water and clothing were in and so stop the bleaching, bleaching and then carry out the stone, the stone is called rinsing (BLEACH STONE WASH). Effect of cellulase enzyme desizing: The purpose of desizing is to remove the slurry on the garment, in order to facilitate post-processing have good conditions. Because denim mostly starch or modified starch slurry, so it can be carried out desizing amylase. Common desizing formula (dollars per liter): BF - 7658 amylase 1 ~ 2g cellulose hydrolysis, salt 2--5g, penetrant 1 ~ 2g cellulase, glacial acetic acid 0.5 ~ 1.5mL, softener 0--2g. Process conditions: pH value of 6 to 7, bath ratio 1: 10-15, temperature 50 ~ 60C, time 30min. Denim is usually due to the residual alkali, desizing bath was added acetic acid, adjusted to pH 6-7, so BF - 7658 amylase best performance.
