Title: Gunter Lorenz: Innovator in Modacrylic Fibres

Introduction

Gunter Lorenz is a notable inventor based in Dormagen, Germany, recognized for his contributions to the field of modacrylic fibres. With a total of eight patents to his name, Lorenz has made significant advancements in the production and properties of synthetic fibres.

Latest Patents

One of Lorenz's latest patents is for gloss-stable modacrylic fibres. This invention relates to fibres and filaments that comprise 50 to 84% of acrylonitrile, 15 to 48% of vinylidene chloride, and 2 to 5% of an olefinically unsaturated sulphonic acid or salt thereof. These fibres exhibit a shrinkage in boiling water of at most 0.3% and a reduction in density on treatment with boiling water of no more than 0.015 g/cc. Additionally, the scattered light component after boiling is at most 35 units compared with a BaSO4 standard of 1000 units, with the increase brought about by treatment with boiling water amounting to no more than 30 units. Another significant patent involves a process for removing residual solvent from dry-spun filaments of acrylonitrile polymers, achieving solvent levels below 2% by weight through a multi-stage hot-wash with low quantities of water.
