But there is still work to do.
A challenge – and an opportunity
The fiber gap presents both a challenge and an opportunity.
The fiber gap refers to the global shortfall between the demand for textile fibers — such as cotton, polyester, wool and others — and the supply of sustainable or natural fibers available to meet that demand.
According to industry data from Textile Exchange, global fiber production continues to rise, while the scalable supply of lower-impact natural fibers remains constrained.
Because natural fibers alone cannot meet growing demand, manufacturers continue to rely heavily on petroleum-based synthetics such as polyester, nylon and acrylic.
Closing this gap requires realism about scale.
In the short to medium term (now–2035), responsibly produced man-made cellulosic fibers (MMCFs), including TENCEL™ Lyocell and Modal are produced from wood 5, a biomass feedstock that can be regenerated through forest growth and reforestation, unlike polyester, which is produced from fossil resources.
If the goal is rapid decarbonization and meaningful volume replacement, MMCFs are the bridge solution.
At the same time, next-generation innovators — including LENZING partners such as TreeToTextile and Circ — are pioneering solutions that could reshape the industry over the long term. These technologies have the potential to disrupt conventional MMCF production, reduce reliance on forestry and enable true textile circularity.
