Maybe you have also had the same question: “Why are most period panties black？”
There are mainly the following reasons:
1. Privacy protection and comfort: Physiological underwear is designed for female friends during menstruation. Using black fabric as the main fabric can provide better privacy protection and avoid embarrassment and anxiety. In addition, women may feel discomfort and fatigue during menstruation, and black fabrics generally have better softness and comfort, which can help relieve discomfort.
2. Easy to deal with stains: Women may encounter various secretions during menstruation, and black fabrics are easier to hide possible stains than bright or bright colors, making underwear cleaning and maintenance more convenient.
3. Market demand: black is a relatively basic and universal color, suitable for all skin tones and personal preferences. Manufacturers typically choose a color that meets the needs of most consumers. Black fabrics are more common in this regard and can attract more potential consumers. Therefore, most manufacturers will mainly promote black, but they will still be based on the wishes of customers and consumers.
As for the specific composition of the four-layer fabric, different brands and products may vary, but generally include the following layers:
4. Inner fabric (direct contact with the skin): usually soft, breathable fabrics, such as cotton or artificial fiber fabrics.
5. Absorbent layer: The layer used to absorb secretions, usually using materials with high water absorption properties, such as absorbent cotton cores, fiber materials, or high-absorbency polymers.
6. Anti-seepage layer: the layer used to prevent secretions from penetrating into the outer layer, usually using anti-seepage materials such as polyethylene or polyurethane.
7. Outer fabric (facing the outside): The commonly used outer fabric is polyester or polyamide, which is waterproof and leak-proof, and can prevent secretions from leaking out.
Choosing a fabric suitable for physiological underwear requires consideration of multiple factors, including moisture absorption, comfort, durability, and ease of cleaning. Here are some common fabric options:
1. Cotton: Cotton is a natural fiber with good hygroscopicity and air permeability, which can effectively absorb moisture and keep the skin dry. Cotton fabric is soft and comfortable, skin-friendly, suitable as the fabric choice for physiological underwear.
2. Polyester: Polyester is a synthetic fiber with good durability and elasticity, and is often used in blended fabrics. Polyester fabric dries quickly and is suitable for athletic underwear, but may absorb less moisture than cotton.In addition, some physiological underwear may also use fabrics with added antibacterial or deodorant treatment for extra protection and comfort.
