Iron yarn
Iron yarn is a heavily finished , multi- twisted and paraffinized cotton yarn . The name refers to the high durability and strength of the material. Contrary to popular belief, iron yarn contains no iron . The manufacturing process of iron yarn is called lustering .
Iron yarn is also known as shiny yarn .
Manufacturing
In the luster process, several cotton threads are first soaked in dissolved starch , paraffin and wax . The threads are then stretched using steel rollers and brushes in the polishing process with the aim of smoothing out all fiber ends . The result is a shiny, very tear-resistant yarn that is extremely hard-wearing.
history
The iron yarn was originally developed in Barmen in the middle of the 19th century by the manufacturers Carl Theodor Wuppermann and Philipp Barthels-Feldhoff . It was used for lacing straps , hat braids , ribbons , linings and as sewing thread as well as in the cable industry. This helped the local ribbon weaving mills to achieve a considerable economic boost in the last third of the 19th century. The Barm-based company Barthels-Feldhoff already employed more than 300 people in iron yarn production in 1875 .
However, this material became known primarily through the Bauhaus Dessau . There, the weaver Grete Reichardt developed iron thread straps that Marcel Breuer used to cover his tubular steel furniture from the 1920s. The connection to the Bauhaus Dessau meant that iron yarn was no longer directly associated with the Wuppertal textile industry .
Today, iron yarn is only used occasionally, for example for true-to-original re-editions of Bauhaus classics .
