“Invention” can be defined as the creation of a product or introduction of a process for the first time.
“Innovation” on the other hand, occurs if someone improves on or makes a significant contribution to an existing product, process or service.
Definition

1. Institutions – which are often neglected but are where the innovations happen. 2. Markets – where the demand and the finance comes from and 3. Technologies – which go hand in hand with innovations
“Innovation is about the smart application of knowledge to solve problems more imaginatively than we have in the past.”

"Dyestone® X Color" is neither pigment nor dyestuff, but a patented new generation of textile colorants that fully utilize micro-encapsulating technology.
Matsui International's insoluble colors are finely ground at the Nano-level and coated with a water-soluble polymer on the surface level and can be applied onto almost any kind of textile substrate (cotton, polyester, nylon, rayon, etc.) by both printing & pad-dyeing process.
