Wacoal Corp., a subsidiary of Wacoal Holdings Corp., announced the opening of the "Melooop Lab" in Minami-ku, Kyoto, in May 2026. This facility serves as a research and development hub for the proprietary "Melooop" technology, aiming to accelerate social implementation through co-creation with internal and external partners.
"Melooop" is a sustainable 3D molding technology characterized by its use of mono-materials, low waste production, and mold-free manufacturing. While previously utilized for Wacoal's "CW-X" sports bra cups and high-fashion collaborations like "doublet" at Paris Fashion Week, the lab will now focus on diversifying applications.
A key focus area is the automotive industry, where there is high demand for lightweight materials and versatile component designs. Wacoal is currently operating two machines at the lab, with plans to expand to a four-machine system by the end of the year. The facility represents a shift from traditional apparel manufacturing to high-tech industrial applications, leveraging over 60 years of data from the Wacoal Human Science Research and Development Center to balance sustainability with high functionality.

FAQ
What are the technical advantages of Melooop?
It uses a melt-blown process to create 3D objects from single materials (mono-materials) like polyurethane, making them easier to recycle. It requires no adhesives, no traditional dyeing processes, and no metal molds.
Why is Wacoal entering the automotive sector?
The automotive industry requires lightweight and flexible material solutions. Melooop’s ability to form complex 3D structures without molds makes it ideal for industrial components and diverse material designs.
What is the role of the Human Science R&D Center in this project?
Established in 1964, the center provides the scientific data on human physiology and material science that underpins Melooop’s development, shifting focus from comfort in apparel to broader industrial innovation.
