Latest Patents
Aikawa's latest patents include innovations that address specific challenges in the industry. The first patent, titled "Composite sheets for wiping cloths," presents a solution to the drawbacks of prior composite sheets made from spun-bonded nonwoven fabric and pulp fibers. This invention provides an inexpensive composite sheet with excellent draping qualities, a nearly fabric-like touch, and good usability. The composite sheet is created by entangling a web of thermoplastic filaments with pulp fibers under a water stream, which is then creped to enhance elongation in both machine and cross directions, achieving usability comparable to fabric wipers.
The second patent, "Process for producing a coated paper," outlines a method for producing coated paper that involves applying an aqueous coating solution onto base paper and drying it. This process utilizes steam or gas composed mainly of steam, which comes into direct contact with the paper sheet. The improvements in heat efficiency and drying rate during this step not only enhance productivity but also ensure the stable production of high-quality coated paper.
