1526536 Packaging fibrous materials TEX INNOVATION AB 17 Nov 1976 [18 Nov 1975] 47905/76 Heading B8C The inter fibre friction in a fibrous sound, or heat, insulation product is reduced by adding a friction reducing agent, e.g. a silicone oil, and/or by reducing the moisture content so that after compression and packaging of the product it can recover to substantially its original volume. The product may contain an adhesive and may be chilled to below the glass transition temperature of the adhesive before compression. The compressed product is packaged in an air and moisture impermeable material. The product may be a sheet, or a web which is compressed and wound up. |
