In the late 19th century, people began to experiment with using naturally extracted gum fibers to weave textiles as a cheap alternative to natural wool thread textiles. The emergence of synthetic fibers brought the end of gelatin textiles before they were promoted. Now the emergence of another new technology in the 21st century may bring a glimmer of hope to gelatin fiber textiles.
It is said that this gel fiber is even comparable to natural Merino fiber, and the production method is also very environmentally friendly, derived from the recycling of animal waste from slaughterhouses.
The process was developed by Philipp Stässel, a student from the Swiss Institute of Technology in Zurich, in collaboration with employees of the Advanced Fibers Laboratory at the EMPA research institute of the Federal Institute for Materials Testing and Development. The remaining animal skins, bones, tendons, etc. from the slaughterhouse can be used as raw materials. Researchers extract collagen from them and convert it into a hydrogel; after heating this gel and adding isopropyl alcohol solvent, the collagen in the precipitation The protein appears at the bottom of the solution. After removing the precipitate through a row of syringes, the fine, almost “infinitely long” fiber drawing is produced through extrusion. These fibers finally pass through the “ethanol bath” through the conveyor strip, and finally the fibers are hardened under the action of ethanol, and finally form a textile pattern. Ball of thread. The luster of the finished product after these treatments is somewhat higher than that of wool fiber, and it is also more soluble in water. So St?ssel treated the product with epoxy resin to make the fibers tighter, then treated them with formaldehyde to make them stronger, and then added lanolin to make them softer.
