R&D

At Kyowa Leather Cloth, we have built unique technologies from the development of materials and design to the production of a wide range of cover materials, sheets and films. We add our advanced technologies to the knowledge we’ve accumulated, and are actively involved in product development.

We apply the experience we’ve gained and our advanced technologies, in the pursuit of even greater added value.

Product development and special technologies

The major materials used at Kyowa Leather Cloth to create our various products are polyurethane, olefin and PVC (polyvinyl chloride). We apply the unique technologies that we have developed over the years for these materials, and create products to match specific purposes.

Material technology

At Kyowa Leather Cloth, we focus on “proactive development” to satisfy our customers' needs for better physical properties (strength, durability against heat and light, etc. ), other functionality, formability and so on.

Design development

We use technologies to express the visually appealing aspects of a product such as color, gloss and grain, as well as texture and feel. Our “LS Grain” technology is continually evolving as we develop our designs. LS Grain is our unique technology that uses CG rendering.

― Comfortable space through chemistry ―

At Kyowa Leather Cloth, we have never been satisfied with keeping our products the same as always.
We continually work in pursuit of greater functionality, as we keep evolving by offering comfortable spaces.

Resistance to mold and bacteria

The antibacterial agents used by Kyowa Leather Cloth are effective against a large number of bacterial strains. Unlike previous antibacterial agents, these agents prevent bacteria from forming in the first place, rather than just killing them. The antibacterial agents we use cover a wide range of fungi that multiply in our living environment. These agents are optimal for products like seating materials on which pets might sit.

Odor resistance

Our products draw in odor-producing molecules through a chemical reaction, rather than by absorbing the smell through tiny holes, such as with activated charcoal. The major benefits of this method are that scent components that were captured are not released, and that even faint smells can be quickly and effectively removed. In addition to perspiration smells containing ammonia and isovaleric acid, our products powerfully draw in VOCs as well, which are harmful to human skin.

Resistance to dirt, ease of cleaning

Since more materials nowadays use white or lighter colors, our products feature surfaces on which dirt does not easily build up. What’s more, the surfaces are easy to wipe off, in case they do get dirty. Our products use stain inhibitors that bond easily with polyurethane and TPO, and which can be applied to many different types of cover materials.

Noise reduction

Our seat upholstery features lower friction resistance, which helps to reduce noticeable squeaking noise.

Anti-warming

Our products contain a combination of anti-warming material to reduce the absorption of infrared rays, which keeps the surface temperature down. This also helps to keep the temperature down inside of the vehicle, contributing to better eco-performance (meaning less use of the air conditioner).

The expressiveness of LS Grain

LS Grain is our original technology for creating surface designs. A fusion of Kyowa Leather Cloth’s unique digital processing technology and our special embossing roll manufacturing techniques has generated this system for creating and manufacturing new grain designs. This system offers vast possibilities for expressive designs using fine engraving at the micron level. It can also rapidly respond to changes in pattern measurements and depth through digital processing, making delicate and finely-engraved designs a reality.
