When you hear “mask,” many people may think of consumer masks sold at drugstores for pollen allergies or influenza prevention. However, the masks we handle include certified disposable respirators that have passed national testing in Japan, N95 particulate respirator, and dust-proof respirators (pleated type, cup-shaped molded type) used in workplaces and medical settings. We offer a wide range of these products, all of which incorporate our nonwoven fabric production and processing technologies.
In environments where dust, welding fumes, or oil mist are generated, the Ministry of Health, Labour and Welfare requires the use of disposable respirators that have passed national certification. Each respirator type manufactured by a company undergoes strict testing for structural and performance standards, and only those that pass are recognized as “nationally certified.” Our disposable respirators are highly reliable products that have passed this certification, specifically DS2 and DS1 standards.
Additionally, the N95 particulate respirators we supply are certified by the U.S. National Institute for Occupational Safety and Health (NIOSH). As high-performance respirators used in medical settings, they play a vital role in infection control and in protecting the safety of healthcare professionals.
What Are Welding Fumes?
The white smoke that appears along with sparks during arc welding is called “welding fumes.” Welding fumes are extremely fine metallic dust particles formed when part of the metal vaporizes, disperses into the air, and rapidly cools. They are a major cause of modern pneumoconiosis.
Nonwoven Technology That Combines Breathability and High Performance
The performance of a respirator is supported by the invisible “power of nonwoven fabric.” For example, you might think that using a highly dense nonwoven fabric would be enough to block dust and viruses. However, if the fabric is too dense, breathing becomes difficult, making it unsuitable for long hours of work.
This is where the “power of static electricity” comes into play. Our disposable respirators use nonwoven fabric made with special fibers charged with positive and negative ions. Because airborne particles are also electrically charged, they are attracted to the fibers and captured as they pass through the filter. This makes it possible to achieve both breathability and high collection efficiency.
We have also refined the respirators’s shape through continuous development. Adjustable elastic bands ensure a proper fit for various face shapes, and a sponge around the nose area provides a snug, comfortable seal.
Layering Technology for More Comfortable Future
Our nonwoven fabrics are more than just materials. They serve as an invisible force that protects health, supporting workers’ safety and comfort. Moving forward, we will continue to advance our technologies and evolve as a global partner in nonwoven solutions—driving innovation to make the future even more comfortable.
