Cross-linked polyol fibrous substrates as multifunctional and multi-use intelligent materials

Although intelligent fibrous substrates were first deseribed and demonstrated in Japan in 1979 with shape memory silk yarn, it is our opinion that the discovery of crease recovery in eellulosie fabries in the wet and dry state by Marsh and coworkers in 1929 was aetually the first example of intelligent materials that even preceded intelligent shape memory alloys. However, this discovery, which later led to the commercialization of durable press fabrics, was never identified or promoted as an intelligent textile concept. 

The shape memory silk yarn was modified by immersion in a hydrolysed protein solution, followed by subsequent drying, crimping, immersion in water and heat setting at high pressure in the wet state. On subsequent heating at 60 °C, the yarn becomes bulky and crimped, but it reverts to the untwisted and
