Title: Shigeru Takemae: Innovator in Slub Yarn Production
Introduction
Shigeru Takemae is a notable inventor based in Nagoya, Japan. He has made significant contributions to the textile industry, particularly in the production of slub yarn. With a total of 2 patents to his name, Takemae's innovations have advanced the methods and apparatus used in yarn production.
Latest Patents
Takemae's latest patents include a method and apparatus for producing slub yarn from filament yarn. This innovative method involves propelling the starting yarn by an air stream at a first rate, allowing it to impinge on a liquid surface. This process opens the yarn to individual filaments, which then entangle and fold together to form thicker portions while being held in a slack condition in the water. The yarn is finally withdrawn at a second rate that is lower than the first. Additionally, the water is preferably whirled to create a vortex, enhancing the yarn's structure through interlacing after withdrawal.
Another patent focuses on a slub yarn where a sheath component is wound around a core component to create multiple slub portions along the yarn's axis. This structure is achieved by simultaneously false-twist texturing both the core and sheath components. The resulting slub yarn features a multilayered winding structure with seven or more layers of the sheath component around the core. The production method includes overfeeding the sheath component in a direction perpendicular to the core component's passage during the twisting process.
