Title: Helen A. Kravas and Water-Based Spin-Finish Innovations.

Introduction

Helen A. Kravas is an inventor associated with Chatham, New Jersey, and has 3 patents. Her patent work includes innovations in water-based spin finishes, which are applied to yarn during manufacturing.

Latest Patents

Kravas’s listed patent, “Viscosity Regulators for Water-Based Spin Finishes,” describes a spin-finish composition containing an associative thickener. The thickener is designed to leave the composition’s initial viscosity largely unchanged, then increase viscosity as water content falls to about 70 percent. As water content decreases further, from 40 percent to zero, the composition’s viscosity remains substantially stable.

The patent describes potential benefits including improved spreadability on yarn, package build, and spin-line coherence, as well as fewer broken filaments and reduced tackiness of residue formed on texturing disks. The composition is also intended to perform consistently despite changes in application conditions such as temperature and humidity.

Career Highlights

Kravas’s listed company affiliations include Hoechst Celanese Corporation and Celanese GmbH. Her patent work reflects an industrial focus on improving the performance and consistency of textile-processing materials.
