Noil Noil Noil is the short fiber left over from combing wool or spinning silk and used as a decorative additive for many spinning projects, like rovings and yarns. Silk noil is also called "raw silk", although that is a misnomer. As noil is a relatively short fiber, fabric made from noil is weaker and considered less valuable. Silk noil may also be made from the short fibres, directly sourced from the silkworm cocoons. Rather than the continuous length of silk, shorter fibers, which are generally not used to create high quality silk are used for silk noil, which has a
Aircraft fabric covering There is also an uncertified light Ceconite of 1.87 oz/yd² (63 g/m²) intended for ultralight aircraft. This method requires physical attachment of the fabric to the airframe in the form of rib-stitching, rivets or capstrips, which are then usually covered with fabric tapes. In addition to Poly-Fiber, a number of other companies produce covering processes for certified and homebuilt aircraft. Randolph Products and Certified Coatings Products both make butyrate and nitrate-based dopes for use with Dacron fabric. Superflite and Air-Tech systems use a similar fabric, but the finishes are polyurethane-based products with flex agents added. These finishes produce very high
