Nissenken and Kawano Lab: A Joint Venture at Science Agora 2026

The Nissenken Quality Evaluation Center, located in Taitō, Tokyo, is set to make waves at the upcoming Science Agora 2026. Taking place on September 12 and 13, 2026, this significant open forum bridges science and society, showcasing top-notch research and innovations.

In partnership with Kawano Lab, Nissenken will present a standout program titled "The Science of Unseen Differences." This exhibit has been recognized as a featured program by the Science Agora 2026 Promotion Committee, ensuring it will attract considerable attention from attendees.

Delving into Quality Evaluation and Resource Recycling

Nissenken is not just about quality testing and evaluation; they are heavily invested in future-facing research that focuses on quality assessment and resource recycling. The exhibition promises to unveil cutting-edge technologies utilizing AI image analysis, near-infrared spectroscopy, and magnetic electrophoresis, aimed at capturing material variances that are not readily visible to the naked eye.

One of the program's pivotal objectives is to transform these unseen differences into tangible data, thus paving the way for advancements in recycling processes and overall quality assessment.

Spotting the Invisible: Using AI and Spectroscopy

Part of the presentation will dive into specific methodologies, such as:

• - AI Image Analysis: This process involves capturing fiber images through a microscope, with AI software identifying and classifying each strand, effectively visualizing material differences.
• - Near-Infrared Spectroscopy: By exposing fabric to near-infrared light, the resulting spectra reveal information about the material composition, illustrating the discrepancies in molecular structures through light data.
• - Magnetic Electrophoresis: This technique focuses on the gradients of magnetic field strength to differentiate materials based on their magnetic susceptibility, enabling classification based on their movement within the magnetic field.

Furthermore, the program will shed light on research sponsored by the Ministry of the Environment, specifically regarding a project led by Nissenken's Miyuki Funahashi on developing a small near-infrared spectrometer to assist in sorting recycled clothing. This innovative device aims to identify the composition of clothing materials, specifically targeting high-fiber content suitable for recycling into new products.

Engaging Visitors: Discovering Fabric Composition

During the exhibition, attendees will have the opportunity to engage directly with the technology by measuring various garments using the small near-infrared spectrometer. Participants can analyze the spectral data to infer the fiber composition of their items, allowing them to consider their recyclability. The device will even automate potential recycling methods based on the analysis results, fostering a dialogue around sustainability in fashion.
