A questionnaire survey using Official The current situation is that I change my clothes, but I don’t get new ones. An overwhelming majority of respondents (84%) said that they consider replacing their product after they notice the appearance of the product, such as dirt or kinks. However, if you wear one piece of innerwear twice a week, it will be washed about 100 times in a year, and the innerwear will become quite worn. For example, when items that contain a lot of cotton are washed and worn repeatedly, the fibers become thinner and the fabric becomes thinner, making it difficult to perform its original function. In order to stay comfortable every day, check your innerwear when changing clothes and consider purchasing new ones.

Check out the replacement sign! ・Discoloration If you notice a change in appearance, such as “it’s turning yellow” or “it’s no longer white,” it’s time to buy a new one. The more you wear it, the more dirt and sebum left on the innerwear become noticeable, and the color may change. ・Odor remains Dirt such as sebum that cannot be washed out through washing becomes more difficult to remove the more times you wash it, causing odor. ・Tear/hole If the strength of the fibers weakens, the fabric will tear or form holes. ・Pilling and fraying As you wear and wash your clothes repeatedly, pilling will occur on the surface of the fabric and fraying will occur on the edges. In particular, many synthetic fibers are sensitive to friction, and innerwear that contains a high proportion of synthetic fibers is said to be more likely to pill. Replacement sign for comfort The dough has become stiff When fabrics that contain a lot of cotton are repeatedly worn and washed, the fibers themselves may become hangnails (tear into small pieces) or become intertwined with each other, making them feel rough and stiff. If you feel that the product feels worse to the touch than when it was new, that’s a sign that it’s time to buy a new one. Not absorbing sweat Decreased sweat absorption and moisture absorption capabilities are also signs that it’s time to replace your product. If the fabric is made of cotton, the fibers will gradually thin through repeated wearing and washing, making the fabric thinner and less able to absorb sweat and moisture. Additionally, even if the material is made of synthetic fibers, the water-absorbing ability of some materials that have been processed to increase their water-absorbing properties may decrease with repeated washing. It’s getting shabby Polyurethane, which is often used to improve stretch, deteriorates the longer it is used, and the stretched fabric may not return to its original state. If you feel like it’s starting to wear out, it’s a sign that it’s time to buy a new one. If you notice a change in comfort, we recommend replacing your innerwear with a new one.
