Vegeto reports its milkweed-fiber nonwoven insulation is ‘three times more effective’ than polyester; Quebec-based parent company Eko-Terre says polyester insulation allows faster air transfer of heat, whereas Vegeto fibers traps air in their lumens

LOS ANGELES , May 20, 2022 () –

Eko-Terre, a Quebec-based textile producer that sources its products from plant fibers, said its Vegeto nonwoven is "three times more effective" at insulation than polyester-based insulation, Innovation in Textiles reported on April 19.

Third-party testing by CTT Group confirmed the findings by starting with a piece of thin, black plastic. The plastic was covered with either Vegeto’s milkweed fiber-based nonwoven or a polyester insulator, which were then subjected to 400 Pa of pressure under 2-kg weights.

With polyester, the plastic piece took 2.2 minutes to reach 33°C. With the Vegeto nonwoven, it took 6.5 minutes to reach the same temperature.

“These results show that the lower thermal conductivity of Vegeto insulation produces a better insulation factor because of the air trapped in the lumens,” said the CTT Group researchers, according to a Vegeto press release. “The heat passes through the polyester insulation more quickly than Vegeto, confirming the thermos effect of the plant-based tubular fibres.”
