Description

Technical Field

[0001] The invention relates to the technical field of textile fabrics, in particular to a multifunctional germanium fiber yoga clothing fabric and a preparation method thereof. Background Art

[0002] As the pace of modern life accelerates, people are facing increasing mental stress and physical burdens. Yoga, as an ancient way of fitness, has become one of the most popular fitness programs in the world because it can improve people's physical, psychological, emotional and spiritual abilities. Female customers in the yoga industry account for as high as 94.9%, and they are concentrated in the middle-aged group of the post-80s and post-90s. According to incomplete statistics, the market size of China's yoga industry has increased from 17.46 billion yuan in 2016 to about 50 billion yuan in 2022, of which the market size of the yoga clothing industry has reached about 15 billion yuan. This market trend has promoted higher requirements for the functionality, fashion and personalization of yoga clothing fabrics.

[0003] At present, yoga clothing fabrics on the market mainly have basic functions such as high elasticity, breathability, and perspiration. Some products also have antibacterial and deodorizing functions. However, as consumers pursue a healthy lifestyle, the functional demand for yoga clothing fabrics is also increasing, especially the demand for fabrics that can emit far infrared rays and release negative ions. Far infrared rays can promote blood circulation, accelerate the expansion of microvessels, help the body keep warm and restore physical strength; negative ions can speed up energy exchange, reduce fatigue, accelerate physical recovery, and inhibit the oxidation of oxygen free radicals, reduce damage to normal tissues and cells of the human body, reduce human aging, and enhance immunity.

[0004] Therefore, a multifunctional fabric is needed, which has the functions of far infrared ray, negative ion, etc. on the basis of the original high elasticity, breathability and perspiration. Summary of the invention
