Title: Innovations of Xiaoming Yang
Introduction
Xiaoming Yang is a prominent inventor based in San Diego, California. He holds a total of nine patents, showcasing his significant contributions to various fields. His innovative work primarily focuses on advancements in dyeing systems and controlled release products.
Latest Patents
One of his latest patents is a color dyeing system for plastic films. This process allows for the continuous dyeing of plastic films, such as polyethylene terephthalate. It involves passing the film through a dye bath that contains dye stuffs dissolved, suspended, or dispersed in a liquid carrier. This carrier is partially made up of a polymer, preferably a polyol, which has at least one free hydroxyl group. The high molecular weight and boiling point of the polyol help prevent the dye from fading, ensuring long-lasting color fastness. Additionally, the rapid diffusion of the dye bath into the film is enhanced through thermal and ultrasonic energization.
Another notable patent is for controlled release urea-based products. These products serve as feed supplements for ruminant animals and as plant nutrients. They consist of particles primarily made of urea, coated with a moisture-resistant interpenetrating polymer network. This coating is created from the reaction products of urea and a polyisocyanate, along with an alkyd resin and an oil. The coated nutrients release their contents at a controlled rate over a specified period, making them economical and efficient for agricultural use.
