I believe everyone knows that the special treatment of webbing includes water washing, machine washing, and dry cleaning. Many people have never heard of enzyme washing, right? Well, today I will explain it to you.
Enzyme is a kind of cellulase, which can degrade the fiber structure under a certain pH value and temperature, so that the cloth surface can be gently faded, and a lasting soft effect can be obtained. Stones can be used in combination or in place of stones. If used together with stones, it is usually called ENZYME STONE WASH. Generally 3-10 grams / liter. If the pH and temperature are too high, the enzyme will lose its activity, and if it is too low, the effect of fermentation will be reduced. The pH is generally controlled at 4.5-5, and the temperature is about 50 degrees.
Biological enzyme desizing requires temperature as a condition, just like yeast, the effect is not good if the temperature is low, the time is long, and the temperature is high and it fails. The general treatment conditions are that the water temperature is 55-80 degrees, and the time is 10-20 minutes. If lye is used, it is best to rinse it once with clean water.
Technological formula: Desizing enzyme/lye solution: 1.6/10 After cleaning, drain water again, add enzymes and buffers, the effect of adding buffers is to ease the effect of enzymes and avoid pattern deviation. This time is based on the samples provided by the customer, and the temperature is 45-55. 2 minutes for the board once. Technological formula: Buffer: PH 4.5-5.3 Enzyme: 2-4 After the effect is achieved, immediately rinse with water, it is best to keep it at 40 degrees during cleaning, speed up the cleaning speed, and ensure that the cleaning is clean. After cleaning, add soap powder and wash at 55 degrees for 5 minutes for further cleaning.
There are many kinds of enzymes. The commonly used enzymes in washing plants are cold water enzymes, hot water enzymes, laccase enzymes, and hair-etching enzymes. For the use of various enzymes, please refer to the instructions provided by the auxiliary manufacturers. They are usually suitable, so don't mess around! Cold water enzyme is generally used at 30 degrees, and it is used for denim blooming; hot water enzyme is used at 55 degrees, which is also used for denim blooming; laccase is generally used at 55 degrees, and the difference from the previous two is that laccase is blooming. At the same time, it has a yellow nostalgic effect; the hair-etching enzyme is used to corrode the cellulose burr and play a role in brightening the cotton fiber. Enzyme is an enzyme, it has specificity and high efficiency, it must be used at a certain temperature and acidity.
I can't stand the practice of using enzymes in washing plants. Please follow the following points after reading this article:
1. The action time of the enzyme is relatively long. Generally, it takes at least 30 minutes to have a certain effect. Please do not drain the enzyme after 5 minutes and 10 minutes of the enzyme! You can choose not to!
2. The enzyme is specific, that is to say, the hair-etching enzyme is not used for denim blooming, please don't say that the denim is not enough, add more enzyme water to turn it, and the turning flower is also the credit of the washing machine!
3. Enzymes must have good activity under certain temperature conditions. Please do not treat cowboys with hot water enzymes without heating! 4. Enzymes are usually more expensive. Usually, adding 1 percent is a large amount. Please turn it on for a longer time.
