This invention concerns a baglike product together with procedures for the manufacture of a composite fabric for the product, which can preferably be utilized as a sleeping or sleeping bag. The bag consists of several layers of thermally insulated fibers as well as non-woven fibers. The bag can be used on more than one occasion, but because of its relatively low price it can be considered as disposable. The composite fabrics is characterized by the fact among others, that one surface of the insulation material is freely exposed, whilst the opposite surface is permanently fixed against one side of the covering and permeable material, so that the insulation material's free surface within the composite fabric lay freely against another area of the insulation material's free surface. One side of the insulation material is fixed against the covering and permeable material by gluing and/or by means of hot welding and/or in combination with ultrasound. Fibers from chemical pulp and/or chemical mechanical and/or mechanical pulp or from regenerated cellulose such as artificial silk are utilized for insulation. |
