Abstract
Abstract Protective fabrics having a reflective surface are made of textile yarns, for example of wool, intermeshed with strands of reflective material, for example a metallized plastics film, a major proportion of the textile yarns being present in one face of the fabric and a major proportion of the reflective strands in the other. The fabric may be woven, for example on a double beam loom, or knitted, as on a double jersey machine. ,he preferred reflective strand is a laminate of aluminium between two polyester films, split into widths between 0.3 and 0.8 mm.
