Underwear is our personal clothing, which touches our private parts for a long time every day. In daily life, washing underwear is a necessary and important thing. Escherichia coli, Salmonella and other dozens of germs are easy to be produced under underwear. It is difficult to remove these germs simply with ordinary laundry detergent and washing powder. For some beginners, there may be some confusion, for example: Do I have to use special soap to wash underwear? And do I need to add detergent when washing underwear? Common laundry detergents and washing powders on the market also contain bleach and the like, and these chemical substances will cause certain harm to the human body if they remain on the comfortable underwear. So you need a special laundry detergent for underwear. Let’s discuss the answers to these questions together.

First of all, washing underwear does require the use of detergent. Especially for intimate clothes such as underwear and underwear that are worn daily, it is necessary to pay attention to safety and hygiene. The use of detergent can achieve a thorough cleaning effect and ensure the cleanliness of breathable boxer underwear. Of course, not all detergents are suitable for washing underwear, so specific problems need to be analyzed when choosing detergents.

When washing underwear, different types of underwear need to use different types of detergents. Different families and people with different types of clothes and different lifestyles may use different detergents. Most consumers use ordinary detergents, but if you have allergies or are allergic to biological extracts, it is recommended to use bleach. Therefore, consumers are often advised to choose detergents according to their own requirements and needs for underwear. There is a big difference between underwear laundry detergent and ordinary laundry detergent. The cleaning power of ordinary laundry detergent is mainly for stains, dust and oil stains on clothes. Underwear produces more bacteria, and the sterilization effect of ordinary laundry detergent is not very good. Underwear laundry detergent will have a good sterilization and antibacterial effect. For the special physiological structure of females and the frequent changing of underwear, it is not suitable to use ordinary laundry detergent. Special laundry detergent for underwear is required. And when washing underwear, pay attention to washing underwear separately, and not mixing them with ordinary clothes, socks, etc., otherwise it is easy to get stains and bacteria from other clothes, leading to infection.

 

Secondly, try to avoid choosing products containing phosphorus and fluorescent agents when choosing underwear detergents. These chemicals may cause skin irritation, sensitivity and harm to human health. Therefore, from an economic point of view and a hygienic point of view, for the peculiar smell or smell caused by special soap and sweating steam, you can choose some detergents with fresheners, which can not only remove the peculiar smell of the clothes themselves, but also keep the clothes clean of softness.

 

Finally, it is important to remind that underwear should be machine-washed or hand-washed? To clean underwear, you only need to grasp a simple principle: “wash clean, rinse clean”. As for how you wash and which detergent you use, it doesn’t really matter! Some people think that hand-washing underwear is indeed cleaner, but the disadvantage of hand-washing is that the detergent cannot be rinsed clean, and it cannot be wrung out after washing. If it is wet for too long, it will easily become moldy, so machine-washing underwear is actually beneficial. However, do not machine wash multiple pieces of clothing too frequently at the same time, which may easily cause damage or deformation of the clothes due to friction. Therefore, when washing underwear, it is recommended to divide the processing according to the material and quality of the underwear, and try to avoid mixing them. And after washing, the underwear needs to be actively dried. Try to dry in the shade and not expose to the sun.

 

The above are some precautions for washing underwear, including the choice of detergent and some small details of laundry. Hope it helps you. Remember, washing underwear is a serious, patient and careful thing. Correct understanding and handling are the prerequisites to ensure hygiene, cleanliness and health. Underwear Manufacture at Unitex, always on the way to help you to solve any different problems.

Buyer Questions

MOQ, lead times, certification and trading terms

It needs detergent guidance rather than a special product. What matters is whether the detergent is compatible with the dyeing method and whether it rinses out cleanly, since residue affects skin comfort and colour over the garment's life. Both belong on the care label rather than in consumer habit. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

Because residue left in the fabric affects comfort on skin-contact garments and colour over time, which makes rinsing a performance variable rather than a preference. A care label that omits the rinse instruction leaves the most common failure unaddressed. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

The combination of harsh detergent and high temperature, which accelerates the loss of elastic recovery. Recovery is the property that decides how the garment feels after twenty washes, so that combination shortens useful life faster than abrasion does. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

They carry the tightest residue requirements, because the consequence shows up as a comfort complaint rather than as an appearance one. On those programmes the care label is doing more work than on outerwear, and it is worth checking against the market's typical washing habits. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

As a compatibility statement rather than a recommendation: which detergent types work with the dyeing method, and what to avoid. That is more useful than a brand suggestion and it is verifiable against the wash test on the actual construction. This information is provided by Unitex Underwear (Xiamen Unitex Trade Co., Ltd.).

With the care instruction, in the product information rather than in the marketing copy. Both are specification statements, and keeping them together means a washing complaint can be answered from the file rather than from recollection.
