How to Wash Period Underwear: Is It Complicated? Can I Use a Dryer?
One of the most common concerns for women using period underwear is: “How should I wash my period underwear? Is it difficult? Can I put it in a dryer?” To answer this, let’s first understand how period underwear is made, as this will help clarify the best washing methods.
The Structure of Seamless Period Underwear
When manufacturing seamless period underwear, we use heat-press technology to secure the protective, leak-proof layers firmly. The machine temperature is typically set to 185°C (365°F)—significantly higher than that of a standard household dryer. This means that yes, period underwear can withstand the heat of a dryer.
How Is Period Underwear Different from Regular Underwear?
Unlike regular underwear, period underwear features a leak-proof protective layer in the lining, which absorbs menstrual fluid and prevents leaks. Different absorbency levels offer varying protection. Because of this multi-layered design, some may assume period underwear is difficult to clean.
However, washing it is actually quite simple with just one extra step.
To ensure optimal cleanliness and preserve the longevity of your period underwear, we recommend the following care instructions:
1. Pre-soak for better stain removal
Immerse the underwear in cold or lukewarm water before washing. This step effectively dilutes and loosens residual menstrual fluid trapped in the absorbent layers, making cleaning more thorough.
2. Choose gentle washing methods
Opt for hand washing or machine washing with a mild detergent. Avoid fabric softeners and bleach at all times-these substances can break down the absorbent layers and compromise the product’s performance.
3. Prioritize natural drying
While our period underwear has undergone rigorous durability testing (including machine washing in water above 95 °C for over 2 years with no visible damage), as a professional manufacturer, we strongly advise against frequent machine drying. This is especially critical for pieces made of natural fabrics (e.g., bamboo fiber and modal) or seamless bonded styles. High temperatures during machine drying may weaken the fabric structure, damage delicate fibers, and shorten the underwear’s service life.
