Latest Patents

Sato's latest patents include a groundbreaking invention related to a thick and thin fiber that features grooves on its surface. This advanced silky thermoplastic polymer fiber is designed to be thick and thin along its axis, incorporating two or more axially-continuous grooves per filament. The grooves have entrance widths ranging from 0.2 to 4 micrometers and depths from 0.1 to 1.8 micrometers. The fiber is produced by dissolving part of an easily-soluble polymer from a drawn composite fiber made of two differently-soluble thermoplastic polymer components.

Another notable patent is for a separable unitary composite fiber, which has a uniformly shaped transverse cross-section along its length. This fiber consists of at least two different polymer components, one of which is soluble in a specific solvent while the other is relatively insoluble. The soluble polymer component is a polyester made up of 80 to 97% by mole of ethylene terephthalate units and 3 to 20% by mole of ethylene 5-sodium-sulfoisophthalate units. The relatively insoluble component can be a fiber-forming polyester and/or polyamide.
