Abstract
The shield comprised at least one thermally insulating assembly formed by a reflecting layer and a spacing layer in which the latter is a knitted product. Preferably, the knitted product is tulle, for example of polyester or polyimide, produced by using a monofilament thread. The production process consists of preferably simultaneously performing the cutting of the reflecting layer and the spacing layer so as to form the edges for the said layers and the welding together thereof by these edges, the cutting and welding processes being performed hot. Application to the thermal insulation of cryogenic instruments carried on spacecraft.
