Abstract (en)
The present invention relates to a method of forming a thermal insulating material which method comprises forming a fibre assemblage from 70 to 95 percent by weight of synthetic polymeric microfibres having a diameter of from 3 to 12 microns; and from 5 to 30 percent by weight of synthetic polymeric macrofibres having a diameter not less than 12 microns, shaping the assemblage so formed, and effecting bonding between at least some of the fibres at their contact points such that the density of the resultant structure is within the range 3 to 16 kg/m<3>, the bonding being effected without significant loss to thermal insulating properties compared with the unbonded assemblage.
