Material of menstrual pants：
The principle of impermeability of trousers during menstruation is simple. In terms of fabrics, there are two main types of trousers during the menstruation period. One is coating impermeable type, which uses textile post-processing technology to improve the impermeable performance of the fabric by coating an impermeable coating on the surface of ordinary fabrics; the other It is waterproof membrane bonding type. Simply put, a layer of physical waterproof polymer plastic membrane is tightly bonded with ordinary textile base materials to give the menstrual period pants an anti-seepage performance. From the appearance point of view, there is not much difference between the two menstrual pants, but the hand feel is obviously different. The surface-coated menstrual pants are correspondingly thicker but relatively soft, and the hand feel of the impermeable part is basically the same as that of other parts; waterproof The film-fitting type of menstrual trousers are relatively thin, and they will feel "sandy" when touched carefully.
Although in general, the breathability of various physiological underwear has been significantly improved compared with previous years, the breathability of the underwear with a waterproof and moisture-permeable membrane is still better, even if it is worn in the midsummer when the weather is muggy, there is no discomfort. At present, there are physiological pants made of coated fabrics in China, which are low in manufacturing cost but have poor sweat permeability, which does not meet the requirements of close-fitting and is not good for women's health.
Due to the effect of elastic fibers such as spandex and lycra in the fabric, the pants are relatively fit, shaped, and have better elasticity during menstruation. Generally, it is enough to buy a fit; sometimes in order to meet the psychological security, choose one to be smaller than usual underwear There is no problem with half-size menstrual pants, but you must follow the principle of small but not big. If it is too loose, the anti-seepage effect of menstrual pants will be compromised.
