Technical Field
[0001] The utility model belongs to the technical field of textile fabrics, and particularly relates to a double-sided mesh concave-convex fabric and a heating fabric. Background Technique
[0002] With the development of society entering the intelligent era, people's requirements for the quality of life are getting higher and higher. In the cold winter, what people pursue is no longer simply cold protection and warmth retention, but more attention is paid to the pursuit of health and beauty. The passive warmth retention method by increasing the thickness of clothes can no longer meet the needs of beauty-loving women with cold-sensitive constitutions and the elderly suffering from rheumatism and arthritis for beauty, comfort and warmth retention.
[0003] The ways of clothing warmth retention are generally divided into two categories: active warmth retention and passive warmth retention. Active warmth retention refers to introducing external heating elements to generate heat independently to achieve the purpose of warmth retention. Passive warmth retention is to control the content of the static air layer by increasing or decreasing the thickness of the clothing itself and prevent the heat of the human body from dissipating outward to achieve the purpose of warmth retention. Traditional warmth retention materials are in the form of passive warmth retention, with a relatively bulky volume, inconvenient movement, and unfashionable appearance. For people working and living in extremely low-temperature environments, passive warmth retention cannot meet their needs.
[0004] Electrothermal fabrics are a type of active warmth retention. Currently, the electrothermal fabrics on the market often only have the heating function, and the heating of the fabric will make the skin of the wearer become dry, which will affect the skin in the long run, so they are not suitable for close-fitting wear.
