Other synthetics—-including polypropylene, acrylic, and Polypropylene had a market share of 2.4%, with fiber production volumes reaching 3.2 million tonnes. The market around 0.4% of global polypropylene production in 2024. Acrylic fibers had a production volume of just under 1.6 million tonnes and accounted for 1.2% of the global fiber market in 2024. Global acrylic fiber production volumes have been declining over the years. The market share of recycled acrylic was estimated to be O.8% of total acrylic fiber production in Elastane fiber production increased from almost 1.4 million tonnes in 2023 to just under 1.5 million tonnes in 2024 and continued to account for around 1.1% of the global fiber market. The share of recycled elastane was estimated to be 3.2% of global elastane fiber production in 2024.1 The production volumes of other synthetics, such as polytrimethylene terephthalate (PTT), polylactic acid (PLA), and similar materials, are very low and are not currently
