MUMBAI, India, Sept. 28 -- Intellectual Property India has published a patent application (202647112911 A) filed by Toray Industries, Inc. on September 21, 2026, for Porous Fiber, Fiber Bundle, Adsorption Column, And Method For Producing Pharmaceutical Using Same.
Inventors include Mayumi Tomohiro; Shiratori Yota; Fujieda Hiroaki; Baba Takeshi; and Fujita Masaki.
The application for the patent was published on September 25, 2026, under issue no. 39/2026.
Abstract: The purpose of the present invention is to provide a porous fiber, a fiber bundle, and an adsorption column incorporating the fiber bundle with which it is possible to efficiently adsorb primarily high molecular weight substances to be adsorbed and removed which are larger than albumin. The present invention provides a porous fiber containing an organic polymer. The average pore diameter in a cross section of the fiber is 100-1,000 nm. The average pore diameter in the fiber outer surface is 100- 10,000 nm. When the average pore diameter in an intermediate region of the fiber cross-section is denoted as Rm and the average pore diameter near the center is denoted as Ri, Rm/Ri is 0.85-1.15. The porosity of the fiber outer surface is 5-50%.
