How are threads made? Thread is produced by twisting fibers from natural sources like silk from silkworms or cotton plants, or synthetic materials like polyester made from petroleum. These fibers go through processes of cleaning, combing, rolling into roving, spinning into singles, dyeing, twisting, and finishing treatments.
