Clothes soaked for a long time laundry detergent is good for example, for a few hours

It's best not to soak for too long. , generally use good laundry detergent, it will be OK in ten minutes, especially if white clothes are soaked with other clothes. After soaking for a long time, the sewage will make the white clothes less obvious. (It's just very old).

Trouble, thanks!

How many degrees is the temperature of the laundry water to remove the dirt Washing clothes at home is often pre-washed. For pre-washing, it can be soaked in water alone or with detergent. The aim is to allow the water to soak the garment well.

When water penetrates deep into the fabric fibers, it dissolves water-soluble soils, thereby reducing the amount of detergent used and enhancing washing efficiency. There is a process of dissolving dirt, and a soaking time is given, but it is not that the longer the soaking time, the better. If it takes too long, the dissolved dirt may re-contaminate the garment, which will reduce the pre-washing effect, or even wash it no matter how much it is washed.

Many people have such an experience, all the dirty clothes that have been soaked for a long time, even if they are washed out, there is a peculiar smell. In addition, the materials of the clothes we wash are different, in addition to natural fibers such as silk, wool, cotton, linen, etc., the use of chemical fibers or synthetic fibers is also very common. Not only natural fibers will denature and shrink, but some chemical fibers will also undergo this change, among which the more obvious examples are acetate and propylene fibers.

This change is more likely to occur in water containing weakly alkaline detergents. Therefore, it is generally believed that it is enough to soak clothes for 20-30 minutes before mechanical washing. The temperature of the water for washing clothes is not always better.

We commonly use a variety of enzyme-containing laundry detergents, among which the enzyme preparations mainly include alkaline protease and alkaline lipase. Alkaline protease is used to decompose protein-like dirt, such as sweat stains, blood stains, etc. Alkaline lipase mainly acts on fatty acids and their ester contaminants, which are commonly referred to as oil stains.

The activity of the two enzymes is temperature dependent, and about 40 is the most suitable. Temperatures that are too high or too low can reduce enzyme activity. Secondly, proteins have a denaturing effect.

Its distinguishing feature is protein coagulation, and solubility is significantly reduced, as in the case of coagulation after boiling eggs. One of the conditions that causes denaturation is high temperatures. The same can be said for protein dirt on clothing.

Therefore, if the water temperature is too high during washing, it will denature and solidify on the fabric fibers, making it more difficult to wash.

No, you cannot.

When washing clothes, soak them in laundry detergent overnight, which will hurt the clothes, because the longer the soaking time, the fibers of the clothes will also cause damage, and the water concentration with laundry detergent is high.

Generally, it is better to soak clothes for 10 to 15 minutes, and of course, depending on the degree of dirtiness of the clothes, appropriately lengthen or shorten the soaking time.

In 1907, German Henkel invented laundry detergent for the first time with borate and silicate as the main raw materials, laundry detergent is an alkaline synthetic detergent, the main ingredient of laundry detergent is anionic surfactant: sodium alkylbenzene sulfonate, a small amount of nonionic surfactant, plus some additives, phosphate, silicate, yuanming powder, fluorescent, enzyme, etc., made by mixing, powder spraying and other processes, and now most of them use 4A fluorite instead of phosphate.

It is not good to soak in laundry detergent for too long when washing clothes. First, the active ingredients in the laundry detergent that are effective for washing clothes have a certain duration, generally about half an hour, and will lose their activity if the time is too long, reducing the washing effect of clothes. Second, soaking for too long will cause damage to the fibers of the clothing.

Third, the sweat and grease attached to the worn clothes will denature after soaking for a long time, and it is easy to produce peculiar smells or adhere to the clothes and it is difficult to clean. Therefore, it is best to soak clothes with laundry detergent in about half an hour, and the time should not be too long.

No, it's just that it stinks when it's hot in the summer, but not in the winter.

No, no, but it's not good to soak your clothes for too long!!

If the clothes are soaked for too long, the chemicals in the laundry detergent and the stains in the clothes are more likely to break down and emit a foul smell. Sewage cannot be lost, and bacteria on the clothes will increase, which will enter the clothing fibers over time, causing the clothes to fade and age.

Many people usually like to put their clothes in and add laundry detergent before washing them.

1. Divide the situation.

2. Normally, it takes about 15 minutes to soak the dirty clothes in warm water with laundry detergent.

3. It takes about 30 minutes to soak the clothes in cold water with laundry detergent.

4. However, if there are no stains on our clothes that are difficult to clean, then there is no need to consume this time to soak the clothes, just simply scrub the sweat stains on the clothes.

1. If it is soaked in warm water, ten to fifteen minutes will do, if it is soaked in cold water, it needs to be soaked for 20 to 30 minutes before washing. If it is dirty, it is generally enough to soak it for about an hour.

2. But try not to reed for more than an hour as early as possible, if there are many clothes, you can extend it appropriately, but one hour is better, because if the clothes are soaked for too long, laundry detergent.

It is easy to wash but not clean, and the laundry detergent is easy to hurt if it is not clean.

Washing powder. You can soak it for a day and a night, but the washing effect is not as good as within the specified time.

Proper use of laundry detergent can improve the effectiveness of laundry detergent, you should first dissolve the laundry detergent with warm water, and then soak the soaked laundry in it, and wash it for the best effect after 15-20 minutes.

It is important to note that the temperature of the water used for the enzymatic laundry detergent should not exceed 60, otherwise the enzyme will be inactivated (ineffective), which will affect the washing effect.

Precautions: 1. After direct contact with alkaline laundry detergent for a long time, the weak acid environment of the epidermis will be damaged, and its effect of hindering the growth of bacteria will also disappear, which can easily lead to itching.

It can even cause allergic dermatitis.

and other symptoms, or leave pigmentation on the **. Therefore, when washing clothes by hand, it is best to use soap.

2. Even if the amount of laundry detergent enters the human body is very small, it will cause poisoning.

3. Ordinary laundry detergent can generally last for two years in the correct storage environment, while laundry detergent with special ingredients may not last for two years. When storing laundry detergent, it is best to put it in a plastic bottle or jar with a lid, on the one hand, it can prevent the laundry detergent from absorbing moisture and agglomerating; On the other hand, it also prevents people from inhaling more synthetic flavors after the fragrance volatilizes.

4. Commonly used lotions are harmful to the human liver; And surfactants.

It is found early on to damage the stratum corneum.

It has caused roughness, and is now regarded as an important public nuisance that pollutes the environment; The alkaline substances contained in strong laundry detergents can not only affect water quality, but also damage human cells.

membrane to denature structural proteins: organochlorine and fluorescent agents contained in whitening laundry detergent.

It is a toxic substance that can easily accumulate in the human body and cause harm to health.

No, because after soaking for a day and a night, there are two disadvantages: the laundry detergent is soaked into the fabric of the clothes, and it is not easy to rinse it clean; The fibers of the clothes will deteriorate due to long-term soaking, and the clothes can easily break if they are washed like this often. Don't soak the water for too long.

It is best to soak it for 20 to 30 minutes before washing, which can not only remove stains, but also protect the clothes.

No. Clothes soaked overnight will have a peculiar smell and are easy to spoil. And because it takes too long, the clothes are not easy to clean and it will be even more difficult to wash. It is best to dissolve the laundry detergent in warm water at 30 to 35 °C, and then soak it for about 15 minutes.

No, it is recommended that you should not soak clothes for more than half a day, otherwise it will cause problems such as dyeing or yellowing, shrinkage, and hardening between different colored clothes.

No, the best time to soak clothes is 15 to 20 minutes.

No, especially white clothes, the bubbles will turn yellow.

No, the poor quality of the clothes will directly accelerate the decolorization of the clothes.

It's not that you can't, it's just that it has to fade.

It's best not to soak your clothes like this.

Laundry detergent is a synthetic detergent with surfactants as the main ingredient. Its main components are: fabric fiber antiscalant, anionic surfactant, nonionic surfactant, water softener, dirt suspension, enzyme, fluorescent agent and fragrance, etc.; Poor laundry detergents often contain harmful ingredients such as phosphorus, aluminum, and alkali.

Generally speaking, laundry detergent is alkaline, although alkalinity is conducive to the washing of clothes, but excessive alkaline substances will bring harm to clothes and **, laundry detergent that has been dissolved in water can be absorbed into the human body through **, long-term accumulation is easy to damage liver function, and even carcinogenic. Generally, in order to achieve a certain decontamination effect, the clothes should be soaked for 10-15 minutes, if the soaking time is too long, the dissolved laundry detergent components will penetrate into the fibrous tissue of the clothes and are not easy to rinse clean, resulting in a large amount of laundry detergent remaining on the clothes, and then causing harm to the human body.

20 minutes. Laundry detergent is an alkaline synthetic detergent, which is a chemical agent used for washing clothes, which was first invented by Hangao in Germany in 1907 with borate and silicate as the main raw materials. The main ingredients of laundry detergent are anionic surfactant, sodium alkylbenzene sulfonate, a small amount of nonionic surfactant, plus some additives, phosphate, silicate, yuanming powder, fluorescent agent, enzyme, etc., which are made by mixing, spraying and other processes.
