1.Shorten the process time and increase production. 2.Environmentally friendly. 3.Reduce water and energy consumption.
Overview
before staining, removal of impurities on the cotton fabric is very important. Refining can remove the wax, pectin, and various pigments. Residual impurities and cotton seed hulls can be wiped off by bleaching. After bleaching the fabric to be dyed, we should ensure that the residual hydrogen peroxide has been effectively removed. Otherwise it will lead to poor reproducibility and dye shade uneven between batches. The traditional bleaching purify using multiple washing method, it takes a lot of water resources. Catalase with its excellent quality of your recommendation and provide a new green technology. Benefits include: • to maintain color consistency between batches • uniform dyeing effect • reduce water consumption and energy consumption.• environmentally friendly .• shorten the process time and increase production .
Application Guidelines: The following guidelines based on conventional technology and production conditions, due to the local water quality and the raw materials, please users experiment it suitable for dosage and conditions according to different actual use.
Catalase suitable for various kinds of intermittent processing equipment, such as yarn dyeing machine, injection overflow dyeing etc.
1) let out of the used liquid oxygen bleaching. 2) Cold water to be cleaned, or directly to join the cold water to fit dyeing bath ratio. 3) plus acid neutralization, the pH controlled at 6-8, temperature is below 50°C,recommended room temperature.4) Add 0.05-0.1g/L catalase (if used for continuous equipment or some processing time, can not lead long , you can increase the amount respectively to 0.5-3g/L). Excessive use of catalase, there is no risk. 5) running 10-20 minutes later, you can test whether the complete decomposition of hydrogen peroxide (hydrogen peroxide test strips that can be used to detect MERCK). 6) Continue in the same bath in dyeing process. Compatibility: Catalase will lose activity at pH below 5 or higher than 11; adding other chemicals may affect its efficacy. The effect of catalase will decrease when the concentration of hydrogen peroxide is greater than 1000ppm. Catalase can compatible with most commonly used surfactants and hydrogen peroxide stabilizers. Therefore, we should test its compatibility before mass production.Product Specifications: Yellow to light brown color varies with the batches. The depth of color does not mean that the level of enzyme activity. Nominal activity was 50000u/ml Standard Packaging: Catalase for (25 kg / barrel or 200 kg / barrel) Storage: Low temperature (4) for 6 months to maintain the original activity, normal temperature (25°C) keep for 3 months its vigor not below logo enzymes. Avoid long-term storage above 30 °C. To prevent direct sunlight, please store in a cool, dry place. Long-term preservation or other hazardous conditions, including higher temperatures may lead to improve the add volume of product.
Safety: Catalase is biological method of fermentation products, avirulent and harmless protein catalyst, non-flammable, soluble in water, completely degradation in the natural state, no pollution, safety and reliability. Protein is potential allergens, during operation do not directly contact with enzyme preparation, avoid long-term inhalation of its dust and aerosol. Skin, eyes or mucosa be stained with enzyme agent, please immediately wash with water.
(no matter according to GB 6944 " dangerous goods and the classification number ", GB 13690 the classification and mark of the dangerous chemicals commonly used "or GB 12268
"List of dangerous goods", the enzyme was not considered dangerous goods. According to GB 20595 "chemicals classification, warning labels and precautionary instructions
Respiratory or skin allergy safety norms "(GHS) enzyme was judged for respiratory allergens.)
