Description

A GABA finishing agent and its application

Technical field

This application relates to the field of textile technology, and to a GABA finishing agent and its application.

Background technique

Health-care clothing is an important branch of clothing hygiene. The British Textile Technology Group was the first to develop textile products with disease-treating functions. In the early 1990s, clothing with antibacterial, temperature-regulating, oxygen-generating, disease-treating and other health-care functions accounted for most of the products. The sales market has greatly promoted the development of health care clothing. In recent years, with the upgrading of consumption, consumers' expectations for products are no longer limited to textiles with a single function. Textile products with health care functions are also increasingly favored by consumers.

The skin is the largest organ of the human body, and transdermal absorption is a commonly used drug delivery method in the field of traditional Chinese medicine. The drug delivery method using the skin as a channel can directly enter the peripheral blood circulation through the cells of the dermis layer and will not be destroyed by the digestive juices of the gastrointestinal tract. The drug delivery efficiency is stable and long-lasting. Many countries have applied traditional Chinese medicine ingredients to bed sheets, underwear, towels, spiritual clothing, pajamas and other skin-friendly textiles to achieve health and wellness by absorbing the beneficial ingredients of traditional Chinese medicine through the skin.

GABA is rich in vegetables, fruits and fermented foods. It is a type of amino acid that is consumed daily. It can act as an inhibitory nerve substance in the central nervous system of the human brain. Studies have shown that GABA can relieve stress, relax the body and mind, and improve sleep. Applying GABA to skin-fitting textile products will replenish GABA for the human body for a long time and exert the effects of GABA for a long time.

The common method of adding functional ingredients to textiles is post-finishing. However, GABA molecules have a simple amino acid structure and are difficult to interact with fibers. Moreover, they have good water solubility. During washing, they are easily dissolved in water and lost from textiles. , therefore, it is very necessary to develop a finishing agent product that can enhance the interaction between GABA and fiber and improve the washing resistance of GABA for the development of health-care textiles.
