Title: Innovations of Robert A. Gill
Introduction
Robert A. Gill is a notable inventor based in Abington, PA (US). He has made significant contributions to the field of non-woven fabrics, holding a total of 5 patents. His work focuses on enhancing the properties of non-woven materials, particularly in applications such as diaper coverstock.
Latest Patents
One of his latest patents is a method of print bonding non-woven webs. This invention concerns a process for preparing non-woven webs that possess a very soft hand and high tensile strength. The process involves print bonding a non-woven web with a formaldehyde-free binder that has a glass transition temperature ranging from about 5°C to about 33°C. The process includes drying, curing, and calendering the non-woven web. The resulting non-woven web exhibits a cross-dimensional water wet tensile strength of at least 150 g/in and a softness value comparable to thermally bonded polypropylene. Additionally, the invention encompasses a product produced by this process.
Another significant patent by Gill is for bonded nonwoven fabrics suitable for diaper coverstock. This invention focuses on a nonwoven fabric specifically designed for use as a diaper coverstock. The fabric consists primarily of fibers and a binder, with at least 50% by weight of the fibers being hydrophobic. The binder is a water-insoluble, hydrophobic emulsion copolymer made from ethylenically unsaturated monomers. The fabric is engineered to have sufficient wet tensile strength for effective use as a diaper coverstock.
