High-end Ripstop Nylon

Mirai is the Japanese word for Future

We firmly believe that each application, with its unique demands, warrants its own distinct fabric. In this regard, Mirai, an economical 40D ripstop nylon, holds promising potential. Introduced in 2005, Mirai was initially conceived as a fundamental ripstop nylon fabric for sport and foil kites—applications necessitating high-quality fabric that is resilient to wear and tear, boasts excellent airtightness, and readily absorbs shocks. It is precisely these attributes that render Mirai an exceptional choice for a diverse array of applications, including inflatable objects, skydancers, art installations, apparel, protective covers, and a variety of medical devices.

With a weight of 48 grams per square meter, Mirai emerges as the fabric of choice for applications where reliability and durability reign supreme, while minimal weight and peak airtightness values take a backseat.

Featuring polyurethane (PU) coating on one side and water-repellent coating on both sides, Mirai offers a soft and tactile feel, facilitating easy deployment and ensuring that designed products retain a natural and smooth appearance. Furthermore, the soft PU coating contributes to Mirai's exceptional aging characteristics; even after extensive use, it maintains its smoothness, shape, and characteristics, guaranteeing sustained performance over time.

Mirai stands as an outstanding, long-lasting fabric offering an unmatched price-to-performance ratio and versatile usability across applications where high performance, durability, and lightweight properties are paramount.

With a weight of 48 grams per square meter, Mirai strikes a perfect balance between durability, reliability and weight. This makes Mirai suitable for kites and/or applications where weight is not the most important aspect.

Air permeability is the ability of a fabric to allow air to pass through it. For Mirai, it is 0,1 cc per cm² per second*, which is considerably low. This means that the fabric is airtight, a feature that is vital for the production of kites. *The air permeability figure indicates the volume of air per surface unit in a certain amount of time. The value is measured at a pressure difference of 1 atmosphere given a certain thickness of the fabric.

Mirai has a little more stretch ability than our other fabrics, Chikara and Icarex. Due to this, Mirai is easy to deploy and will create any designed product shape whilst looking natural and smooth. Precautions have been taken to ensure that the fabric does not have too much stretch to make sure that products made with Mirai will retain their shape for long periods of time.

Mirai has a very high tear strength. This makes it an incredibly durable fabric, meaning that it is resistant to wear and tear. This also guarantees that Mirai will last for a long period of time, during which its performance will also remain undiminished.

Many nylon fabrics are attacked by ultraviolet radiation and may crack or disintegrate if they are not UV-stable. This is a problem known as UV degradation, and is common in products exposed to sunlight. Mirai has good UV resistance. This can be seen through the many kites that have been created using Mirai, all of which have shown little or no signs of UV degradation.

Mirai fabric is polyurethane (PU) coated on one side, which gives it a nice and soft feel. This makes it easy to deploy the fabric and gives it the ability to be used to make any designed product shape, whilst looking natural and smooth. The coating also adds to the excellent ageing characteristics of the fabric – even after intense use it will still look nice and smooth. Mirai also retains its shape, colour and features very well, guaranteeing undiminished performance for a long period of time.
