I'm reaching out to explore your elastic Velcro fabric, as we're in the process of developing a prosthetic interface. We're looking for a stretchable fabric that's compatible with Velcro for a soft sleeve to fit over a prosthetic socket, acting as a base for modular attachments. The fabric needs to have both good elasticity and a loop surface for effective interaction with Velcro hooks. Could you please send us a sample to assess its stretch properties, texture, and hook compatibility? Additionally, let us know if there are any costs involved for the sample and your shipping procedures. Thanks for your assistance!
