Title: Kenichi Akaki: Innovator in Stretchable Materials
Introduction
Kenichi Akaki is a notable inventor based in Kagawa, Japan. He has made significant contributions to the field of materials science, particularly in the development of stretchable sheets and composite materials. With a total of 5 patents to his name, Akaki's work has garnered attention for its innovative approaches and practical applications.
Latest Patents
One of Akaki's latest patents is a method of manufacturing a stretchable sheet. This method involves passing a nonwoven fabric, which includes a plurality of types of fibers, through a gap between a pair of gear rolls. These rolls rotate while engaging with one another through a series of teeth formed on their outer circumferential surfaces. The process draws the nonwoven fabric in a circumferential direction, with a circumferential velocity ranging from 50 to 300 m/min. Additionally, the maximum value of distortion per unit time applied to the nonwoven fabric in the gap is maintained within a range of 5 to 100 seconds.
Another significant patent is for a composite sheet and absorbent article comprising this composite sheet. This innovative composite sheet has a low basis weight and is designed to prevent breaking during the production of absorbent articles or during use. It is formed by bonding a stretch nonwoven fabric to a nonstretch nonwoven fabric using an adhesive. The stretch nonwoven fabric is bonded in a stretched state, featuring alternately formed strip-form sparse and dense regions on each side. The composite sheet boasts a maximum breaking strength of 20 N/50 mm or higher, making it both durable and user-friendly.
