Most of the current popular health skin care products are cosmetics, the number of health skin care textiles is small, and most of the household textiles on the market are conventional fabrics; the market research finds that consumers have more demands on healthy skin care textiles, and the product market prospect is wide.
Nicotinamide, also known as vitamin B3, is a water-soluble substance that can be widely distributed in the body, is a bioactive form of niacin, and has good human body compatibility. Nicotinamide has the functions of promoting skin blood circulation, resisting aging, improving skin dullness and the like, has the effects of whitening skin, moisturizing skin and the like, and is widely used in whitening cosmetics. The method is a great innovative measure in the current stage of adding nicotinamide to household textiles. When sleeping, the contact and friction between the skin and the anti-woven fabric transfer part of the nicotinamide from the textile to the skin surface, thereby increasing the nicotinamide content on the skin surface and leading the consumer to carry out 'beauty' while sleeping.
Niacinamide is powdery and stable at pH6-7, limiting its processability; the nicotinamide has lower melting point and boiling point, and has volatilization risk during drying and shaping; the nicotinamide has a simple molecular structure, does not have a polar functional group, cannot be directly connected with the fabric, and has poor washing fastness. These characteristics limit the use of niacinamide on fabrics.
