Wearable Gelatin: Fashion’s Newest Textile
Approximately 92 million tons of textile waste is generated globally per year,Ìý. CU researchers envision a different future for fashion.
A team led byÌýEldy Lázaro Vásquez (PhDCTD’25), a doctoral student in theÌýATLAS Institute, is busy developing methods to make recyclable clothes from gelatin, the common foodstuff in products like Jell-O and marshmallows.
The team that spins textile fibers made from gelatin. These “biofibers� feel a bit like flax fiber and dissolve in hot water within a few minutes to an hour.
“When you don’t want these textiles anymore, you can dissolve them and recycle the gelatin to make more fibers,â€� said Michael Rivera, a co-author of the research and assistant professor in the ATLAS Institute andÌýDepartment of Computer Science.
The machine, which is small enough to fit on a desk andÌý, heats up the gelatin and uses a plastic syringe to squeeze out droplets of the mixture. Two sets of rollers in the machine then tug on the gelatin, stretching it out into long, skinny fibers — not unlike a spider spinning a web from silk.
“With this kind of prototyping machine, anyone can make fibers,� Lázaro Vásquez said. “You don’t need the big machines that are only in university chemistry departments.�
She added that across the U.S., meat producers often discard gelatin that doesn’t meet quality control standards. Lázaro Vásquez bought her own gelatin, which comes as a powder, from a local butcher shop.
Lázaro Vásquez envisions that designers could tweak the chemistry of the fibers to make them a little more resilient — you wouldn’t want your jacket to disappear in the rain. They could also experiment with spinning similar fibers from other abundant natural materials like chitin, a component of crab shells, or agar-agar, which comes from algae.
“We’re trying to think about the whole lifecycle of our textiles,� said Lázaro Vásquez. “That begins with where the material is coming from. Can we get it from something that normally goes to waste?�
