Latest Patents

Yoshikata Ohno's latest inventions include two significant patents:

1. **Composite Staple Fiber and Process for Producing the Same**

This patent describes a unique composite staple fiber where two polymer components are alternately arranged within a fiber’s cross-section. The fiber's surface is fully covered by one polymer component, which enhances its integrity during treatments such as carding and needle punching. The invention facilitates the creation of flat ultrafine fibers with a sharp-edged structure, which are subsequently finely divided through water jet entanglement.

2. **Filling Material and Process for Manufacturing Same**

The second patent focuses on a filling material composed of crimped fibers joined at one end, resulting in high density. The fibers exhibit crimps in varying phases, allowing them to remain free at the opposite ends. This unique arrangement enables the material to provide exceptional bulkiness and thermal insulation due to the resiliency of the crimped fibers, which effectively trap air within, enhancing its insulative properties.
