Underwear is our most intimate item. Newly bought underwear looks clean and beautiful on the surface. In fact, it contains many bacteria and many additives. If you wear newly bought underwear without washing it, it will not do any good to your body. Through this article, let’s learn how to clean newly purchased underwear correctly before wearing it. What will be the impact if you wear new underwear directly?

 

Can I wear the newly purchased underwear directly?

Many people think that the underwear they buy is new and does not need to be washed. They wear the newly bought underwear directly without washing it. Remember, new underwear must be washed before wearing it! New underwear bought from the market is the best. Best to wash and wear again. This is because manufacturers often use a variety of chemicals to treat fabrics to make their products beautiful and for storage purposes. The purpose of washing and wearing is to remove these chemicals that are harmful to the skin.

 

It is indeed cleaner to wash underwear by hand, but the disadvantage of hand washing is that the detergent is often not rinsed away, and it cannot be properly wrung out after washing. If the underwear is kept wet for too long, it will easily become moldy. Therefore, washing underwear in a washing machine actually has some advantages.

 

In fact, you only need to follow a simple principle to clean your underwear: “wash them clean and rinse them clean.” It doesn’t matter how you wash them or what kind of detergent you use. Before throwing your underwear in the washing machine, you should pay attention. If girls have secretions, or boys have protein molecules from wet dreams, they should simply scrub them with detergent. Otherwise, a layer of biofilm will easily adhere to them and cause bacteria to breed.

 

If you throw your underwear in the washing machine, it is best to wash it with light-colored clothes to avoid mixing it with outer pants and socks. It is also best to put it in a laundry bag to avoid scratching it due to friction. If you are worried that it will not be washed clean, you can put it in the laundry bag. Put a few laundry balls inside to increase the friction of washing.

The following will teach you the correct way to clean underwear from a scientific and practical perspective.

 

The correct way to clean new underwear

  1. When washing your underwear by hand, how much force you use will cause different damage to the material of the underwear. It is best to use gentle pressure and patting with your hands, or to wash it by scratching. It is also taboo to directly wash it like most lazy people. Putting underwear in the washing machine and letting the washing machine rotate, stir and dehydrate will seriously deform the underwear. No matter how good the underwear is, it cannot withstand such abuse, especially underwear with wires or steel rings.
  2. The best cleaning agent – soap powder. You cannot use laundry detergent to wash underwear. It is best to choose soap powder. Generally, natural soap powder is more suitable for washing underclothes, infant clothes and diapers. Let’s get to know soap powder: Soap powder is a powdered soap washing product. The decontamination principle of soap powder is the same as that of soap. It is physical, natural and low-irritation. At the same time, it also retains the good decontamination power of soap. Moreover, the natural decontamination active ingredients added to the soap powder can also protect the fabric. The washed clothes can be fluffy and soft without using softener, which solves the problems of dirt accumulation, hardening and static electricity on the fabric after repeated washing. The effect is better than Laundry detergent is better. In addition, the foam produced by soap powder washing is small, which makes it easier to rinse when machine washing, avoids residual substances from irritating the skin, and saves water. It can be said that it kills two birds with one stone!
  3. Dry after washing. As mentioned before, do not put it in the washing machine for dehydration. This will cause serious deformation of the underwear. Many people say that they hang or dry their underwear directly after washing. In fact, this is not correct, as the underwear will be easily deformed. We can use a dry towel to fully absorb the moisture on the underwear and then dry it. Dry.
  4. Arrange and fold the next step is how to organize and fold the underwear. Random placement will deform the underwear. Therefore, when folding, for non-wire underwear, you can fold one cup into the other cup, and then put the shoulder straps and back inside Lined. If it is a bra with wires, you just need to spread it out flat, and the underwear can be rolled into a round shape, which is very easy to pack and saves space.

 

5. Small issues that need to be paid attention to when cleaning. Some people’s washing machines are never cleaned and will be washed as long as they can rotate. The inner wall of the drainage area is full of cloth scraps and dirt, which breeds many viruses and bacteria. During the laundry process, these dirt and bacteria will be contaminated on the clothes, which is another important reason why you cannot use the washing machine to clean underwear. It is best to wash underwear and other clothing separately, and wash non-dirty and dirty items in order.

The editor here reminds everyone that although the underwear is new, you don’t know what it has gone through before it gets to you. What, for the sake of your own health, you should wash it more often before wearing it to be more assured and safer.

Buyer Questions

MOQ, lead times, certification and trading terms

Yes. The reason is not the store but what remains on the fabric: finishing residues from dyeing and printing, sizing agents applied for handling, and dust from the cutting and packing stages. Rinsing those off is a comfort measure on skin-contact garments. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because the first wash is where a construction that tolerates heat and one that does not diverge. A bonded waistband, a printed panel or a heat-applied label each carry a limit, and the instruction is what tells the customer how to handle the garment without damaging it. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Rinsing, which is why the rinse instruction belongs on the label alongside the temperature. Residue affects comfort and colour retention over time, and it is the part of the instruction most often left implicit and therefore most often missed. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

It can if the instruction does not match the construction. A wash that suits the fibre can still affect an adhesive waistband or a printed panel, which is why the instruction should be written against the construction and confirmed by a wash test rather than inherited from a fibre default. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

The requirement does not, but the habits do. Markets differ in typical washing temperature and detergent use, which is why the instruction should be checked against the habits of the market the range sells into rather than against a single standard. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

By treating the care instruction as a specification item rather than a label printed at the end. A first wash that damages the garment is a complaint, and it is cheaper to specify the instruction correctly than to answer the complaint afterwards.
