Title: Wido Nijenhuis: Innovator in Fiber Recycling and Manufacturing

Introduction

Wido Nijenhuis is a notable inventor based in Huissen, Netherlands. He has made significant contributions to the field of fiber recycling and manufacturing, holding a total of 3 patents. His innovative approaches have the potential to revolutionize the way aramid fibers and polyetherketoneketone fibers are produced and recycled.

Latest Patents

One of Wido Nijenhuis's latest patents is a continuous process for recycling aramid fiber. This process involves combining aramid fibrous material, including non-continuous aramid fibers, with sulfuric acid to create a spin dope comprising aramid. The spin dope is then processed into a continuous aramid fiber. This invention also includes a multifilament yarn made from the continuous aramid fiber.

Another significant patent is for the manufacture of polyetherketoneketone fiber. This process entails mixing polyetherketoneketone with sulfuric acid at a concentration of at least 90 wt % to obtain a spin dope. The spin dope is then passed through a spinneret into a coagulation bath, resulting in fibers that can have varying crystallinity and sulfur content. These innovations are crucial for developing hybrid yarns and composite materials.
