Synthetic spider silk makes its way into fashion
We’re constantly looking for innovative ways to improve the Springwise experience, and so we’re now introducing BeeLine Reader, a new technology that helps you read more quickly and efficiently. To learn more about BeeLine Reader, an award-winning startup funded by Intel Capital, see BeeLineReader.com.
We have already seen clothing made from recycled shopping bags and clothing made from materials grown by bacteria, now a biotech startup has found a way to make clothing from spider silk and its leading the way into the high fashion market. Spider silk is soft, flexible, and strong as steel. But it’s also very difficult to mass produce. Spiders cannot be raised in large quantities, and harvesting the silk is very difficult. Previous attempts to manufacture synthetic spider silk included breeding genetically-modified goats which expressed spider silk proteins in their milk. However, the silk proved too expensive to manufacture commercially. Now, scientists at Bolt Threads have come up with a technique for growing synthetic spider silk using yeast.
