Sontara®

Sontara® is the trademark for a highly functional non-woven fabric developed by E.I. DuPont of the U.S. At Hogy Medical, we have enhanced this material through processes that improve its softness or water repellence to produce a line of disposable items aimed at preventing hospital infections including surgical gowns, drapes, caps and underwear.

Thanks to their excellent barrier performance against scattered fluids including blood, other body fluids and physiological saline solution, helping prevent hospital infections such as MRSA, hepatitis B and HIV while also reducing work in various areas due to their disposable nature, Sontara® products have achieved a 40% share of the overall medical equipment market and a 70% share of the surgical equipment market.

Why Sontara®?

Sontara® (developed by DuPont of the U.S.) is a unique material that combines the strengths of non-woven fabrics and linen and offers barrier and drape features. It is produced by the spunlace process (developed by DuPont) in which high-pressure water is utilized to enmesh the fibers with each other without the use of adhesives or thermally fused resins. This process gives the material the following features:

  1. The fibers are tightly enmeshed with each other, producing a material with no holes and resulting in excellent barrier performance.
  2. The material is soft and drapes very well.
  3. A water-repellent treatment can be applied to prevent blood or other body fluids from soaking into the fabric.
  4. The material consists of wood pulp and polyester (PET), a material used in food packaging. (The pulp is obtained from trees that are planted and harvested under strict control.)
  5. The material can be cut into various shapes without unraveling or creating lint.
  6. Since no adhesives or thermally fused resins are used, there is no concern regarding residual chemicals or binder material seepage caused by heat from friction.
This is why we chose Sontara®.

When the surfaces of Sontara® and linen are compared under a microscope, you will notice that there are hardly any spaces between the fibers in Sontara® (photo 1). Meanwhile, linen has holes that average 50µm in size where the threads intersect (photo 2). Hogy Medical was one of the first companies to utilize the excellent barrier characteristics of Sontara® in a wide range of products including drapes, gowns, underwear, caps and sterilization wraps, all of which have been designed to prevent infections and protect medical staff.

Of all the medical materials available on the market today, Hogy believes that Sontara® is the best. We are also involved in ongoing research and development in pursuit of the "best of the best" or "materials of the future" as the leader in the field of non-woven medical fabrics in Japan.
