How long should you soak a cultural shirt for? Many people soak the clothes for a period of time when washing their cultural shirts, which makes them easier to wash and cleaner. However, people have not always mastered the soaking time very well. So, what is the most appropriate length of soaking time for washing cultural shirts?
Generally speaking, after washing and soaking ordinary dirty cultural shirts for about 17 minutes (normal temperature, ordinary washing powder) and then washing, the cleanliness of the resulting clothes will be optimal. .
1. The length of laundry soaking time determines whether it can save energy and water:
Assuming that the soaking time of clothes in water is optimal, this can improve the laundry efficiency during formal laundry The chemical cleaning power of the washing powder can be fully exerted to reduce the consumption of electricity and the number of washings, and can shorten the mechanical washing time and the degree of wear and tear of the washing machine on the clothes during the washing process, so as to weaken the noise and vibration of the washing machine. Extend its life.
Therefore, it achieves the effect of saving energy and water.
2. Decontamination process of washing powder: The entire washing process is carried out in the medium (tap water). The adhered dirt items (carriers) are put into the medium in which the washing powder is dissolved. The items to be washed are first wetted, and then some dirt is dissolved. The washing powder loosens the attraction between the dirt and the dirt; the dirt is removed. Destroyed into tiny particles; some dirt is emulsified or dispersed in the medium with the help of mechanical stirring or scrubbing. The dirt is swept away into the water. At this time, the solid particles rely on the dispersion of the active substances of the washing powder, and the grease and dirt will no longer be deposited on the surface of the dirt with the help of its emulsification and solubilization. Therefore, the decontamination effect of laundry detergent is actually a comprehensive expression of the basic effects of several processes such as wetting, emulsification, dispersion, and solubilization. Therefore, during the washing process, it is necessary to prevent dirt that has been dispersed in the medium from redepositing on the surface of the item.
3. The effect of enzymes on soaking time (can be advanced appropriately): Adding enzyme preparations to ordinary washing powder is called enzyme-added washing powder. Enzyme is a specific biological catalyst. Protease can catalyze the hydrolysis of meat, egg, milk stains, amylase can catalyze the hydrolysis of sauce, porridge and other stains, and lipase can catalyze the hydrolysis of various animal and plant oils, human sebaceous gland secretions and cosmetics. Dirt, cellulase can make fabrics brighter and remove granular dirt, which is beneficial to the rapid removal of dirt. Therefore, the presence of enzymes can shorten the optimal soaking time of clothes.
4. Different stains are suitable for different water temperatures (under the condition of soaking for 17 minutes):
General stains: the water temperature during laundry should be soaked between 30 and 40°C (less than The water temperature of 30℃ will prevent the washing powder from being completely dissolved), and the cleanliness of the resulting clothes will be optimal.
Blood stains: The water temperature during laundry is normal temperature. Soaking between 30 and 40℃ will ensure the best cleanliness of the clothes.
Sweat stains and fruit stains: When washing, soaking in water at room temperature to 45°C will result in the best cleanliness of the clothes.
Oil stains and soup stains: The water temperature during washing is 45℃-55℃ for soaking, and the cleanliness of the resulting clothes will be optimal.
