Resona Bio Active Double Knit Shirt

Resona Bio, a self-medication wear, is a new concept in textile products developed based on this principle.

"Why do capillaries dilate, leading to increased tissue blood flow?"

"Why is blood circulation promoted?"

Please experience the quality we offer after confronting these questions.

The "Resona Bio material," a natural special mixed powder micronized into ultra-fine particles, is the world's first textile material that has succeeded in increasing peripheral blood flow by achieving resonance with the "frequency of all human bodies," which varies individually.

■ Effects and Efficacy
・Promotes blood circulation
・Relieves fatigue
・Improves muscle stiffness
・Alleviates coldness

■ Features
1. Far-infrared radiation (Nissenken Quality Evaluation Center)
2. Negative ion generation (Kaken Test Center)
3. Anti-static (Kaken Test Center)

■ Material
A double-knit material that is comfortable to wear yet resistant to losing its shape.
It is made by knitting two fabrics, a surface and a lining, together with connecting yarn.
The connecting yarn, which supports the surface and lining, is knitted to create an air layer between the surface and lining fabrics. It has a three-dimensional feel and thickness, is soft with moderate stretch, resistant to losing its shape, and comfortable to wear. It is also soft to the touch and provides warmth.

■ Design
A double-knit shirt finished with a relaxed fit.
The design features a rounded silhouette that naturally drapes the body, such as dropped shoulder lines. The collar, cuffs, and hem use a slightly thinner rib, giving it a light feel that can be worn in any situation.

In the northern part of Mie Prefecture, where the spinning of cotton yarn has been prosperous since the Meiji era. In 1952, Katayama Meriyasu Co., Ltd., a circular knitting factory, was founded. Since its inception, we have developed and produced various circular knitted fabrics. At that time, it was an era of mass production and mass consumption. Amidst the import of cost-competitive materials from overseas and the increasing demand for synthetic fibers, the prototype fabric for "smile cotton" was completed in 1973. However, at that time, commercializing smile cotton was not feasible due to technical and cost issues, and more importantly, "smile cotton, which is gentle on the skin," was not in demand. "We want to create a fabric with the softness and comfort of cashmere using cotton." With this desire, we repeatedly improved our technology, and by the time we were able to commercialize it, 20 years had passed. In 1995, Smile Cotton Co., Ltd. was established. Humans have worn clothes and lived in contact with many materials since the moment they were born. We believe that our mission at Smile Cotton is to continue creating materials that make people instinctively stroke them, smile, the moment they touch them and the moment they wear them.
