Title: The Innovations of Shoji Orino

Introduction

Shoji Orino is a notable inventor based in Ehime, Japan. He has made significant contributions to the field of acrylic fiber technology. With a total of 2 patents, his work focuses on the production of multi-layered conjugated acrylic fibers.

Latest Patents

Orino's latest patents include a method for the production of multi-layered conjugated acrylic fibers. This innovative fiber comprises different acrylic polymers that are conjugated along the fiber axis in layers. On average, the fiber contains more than two layers of acrylic polymers. The shrinkage forming ratio in boiling water of the conjugated acrylic fiber is between 7-15%, and the shrinkage forming stress is 5-20 mg/denier. To enhance water absorbency, one or more of the acrylic polymers may contain 0.3 to 2.0 mmole/g of carboxylic acid groups. The fibers are produced by introducing the polymers into a static mixer, ensuring the retention of separate layers, and then passing through a spinneret. After spinning, the dope is drawn, washed, and dried. If water-absorbent fiber is not required, a shrinkage forming treatment and redrawing follow. The water-absorbent fiber is treated with an alkali solution, either in yarn form or as a fabric.
