Title: Hiroaki Date - Innovator in Polyamide Yarn Technologies
Introduction
Hiroaki Date, an accomplished inventor based in Otsu, Japan, holds a remarkable portfolio of 8 patents. His innovative work primarily focuses on advancements in textile technologies, particularly concerning polyamide yarns.
Latest Patents
Among Hiroaki's latest patents are two noteworthy inventions: the Crimped Polyamide Yarn and the False-Twisted Low-Fused Polyester Yarn. The Crimped Polyamide Yarn is engineered to provide stretch and pliability through the incorporation of low water absorption polyamide fibers. This design allows the natural stretch properties of the crimped yarn to be fully realized in woven or knit fabrics. The yarn is a composite featuring at least 40 mass % of low water absorption polyamide, which has a minimal water absorption ratio of 5% or less at a temperature of 30°C with 90% relative humidity. With a crimp elongation ratio of 25% or more, this innovation represents a significant milestone in fabric technology.
Additionally, the False-Twisted Low-Fused Polyester Yarn consists of a unique structural composition where non-untwisted parts alternate with over-untwisted and non-twisted crimped parts. This configuration enhances the yarn's properties, ensuring optimal performance in various applications while maintaining a degree of fusion-bonding of no more than 50%.
Career Highlights
Hiroaki Date has contributed significantly to leading companies in the industry, notably Toray Industries, Inc. and Toyota Jidosha Kabushiki Kaisha.
