Effect of cellulase enzyme desizing: The purpose of desizing is to remove the slurry liquid cellulase clothing 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, salt 2--5g, penetrant 1 ~ 2g, glacial acetic acid, 0.5 ~ 1.5mL, softener 0--2g. Conditions: pH value of 6 to 7 cellulase, liquor 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. Guangzhou Long Li Biotechnology Limited mainly engaged in biological enzyme and textile auxiliaries, the main products are: Acid cellulase, neutral cellulase, the original enzyme, laccase, desizing enzymes, oxygen enzyme; anti-pollution pink anti-agent, enzyme water special anti-agent, anti-pollution soap oil, NP8.6, brighteners. Biotechnology Co., Ltd. Guangzhou Long Li share little common sense knowledge of denim fabric - denim fabric thickness depending on the thickness of denim, from thin to thick in turn divided into 4.5 Ann, Ann 6, 8 Ann, 10 A, 11 An efficient cellulase, 12 Ann, Ann 13.5, 14.5, etc. Ann. Ann is very thin as 4.5 cellulase preparation, often used for summer clothing, such as vests, sleeveless Shandeng 14.5 Ann is very thick, used winter coat, cotton jacket can be, but we often wear jeans mostly from 8 An An-12 range. (Note: Ann, that ounce, also the ounce, is a unit of weight; weight per square yard, said xx ounce, also said that cotton jeans tightness).
