Bonded Lockstitch for Insulating Blankets
Improved sewing technique for high-temperature insulating blankets prevents stitch failure in hot, turbulent environments. Standard lockstitch modified to isolate single-stitch failures. Bobbin thread kept at blanket surface. Silicone adhesive applied to all bobbin/needle intersections, so failure at one point will not propagate along thread. Suitable for use in aerodynamic and other applications where there is turbulence.
