Vellux is a synthetic that is very light-weight, yet durable, insulates well, and feels soft as velvet. The name derives from "vel" for velvet, and "lux" from the Latin for light. The blanket material consists of two layers of foam melted onto a net and covered with nylon flock, requiring no weaving at all. Francis Spencer's name is on patents for both the machines and the process of making Vellux blankets.
