Title: Ramunas L Valteris: Innovator in Fiber Technology

Introduction

Ramunas L Valteris is a notable inventor based in Seaford, DE (US). He has made significant contributions to the field of fiber technology, holding 2 patents that showcase his innovative approaches to producing staple fibers.

Latest Patents

One of his latest patents is focused on the "Process of making staple fibers." This invention provides improved staple fibers and processes for producing them, particularly useful for forming staple fibers from poly(trimethylene terephthalate), especially carpet staple fibers. The processes include prewetting undrawn yarns and drawing the fibers under wet and warm conditions, thermo-fixing the texture, and drying at relatively low temperatures. The fibers produced according to these processes exhibit improved properties and reduced brittleness compared to those prepared using conventional methods.

Another significant patent is the "Plate, foam and screen filament quenching apparatus." This apparatus is designed for quenching synthetic filaments and comprises an elongated chimney, a porous open-celled foam sheet, which divides the chimney into a plenum chamber and a quenching chamber. Filaments pass through this setup from an extrusion device to a collection means, with a flow of gas supplied to the plenum chamber. The improvement includes a mesh screen positioned between the foam sheet and the quenching chamber.
