Title: Innovations by Leonardo B Guerrero in Nonwoven Fabric Technology

Introduction

Leonardo B Guerrero is an accomplished inventor based in Franklin, MA, who has made significant contributions to the field of nonwoven fabric technology. He holds two patents, showcasing his expertise and innovative spirit within the industry. His work has enabled advancements that hold promising applications in various sectors, including textiles and packaging.

Latest Patents

Among his latest inventions is the patent for a thermally apertured nonwoven product and the process for making it. The process combines one or two outer nonwoven layers with a layer of polymeric material that features a lower melting temperature. This material shrinks when melted, and by applying heat and pressure through a calender roll, the polymeric layer bonds to the fibers of the nonwoven layers. As it shrinks, it pulls the fibers away from the calendaring points, thus generating apertures within the nonwoven fabric. This method can utilize polyethylene or polypropylene fibers, with the polymeric layer often made from thin plastic films such as polyethylene stretch-wrap or elastomeric materials. Additionally, these innovations can involve the creation of bi-laminate or tri-laminate products, showcasing versatility with different fiber types and configurations.

Career Highlights

Leonardo is affiliated with International Paper Company, where he continues to cultivate his expertise in nonwoven technologies.
