Abstract
1,079,590. Moulding porous blocks. E. I. DU PONT DE NEMOURS & CO. Nov. 9, 1965 [Nov. 10, 1964], No. 47446/65. Heading B5A. [Also in Division D1] In a process of moulding a porous, bonded fibrous block, parallel rows of fibrous elements 10 are packed into a mould 22 and adjacent rows are arranged in staggered relationship, the body of elements is then compressed along an axis perpendicular to the parallel rows at a compression ratio of 2 to 8 and to a final density of from 0À2 to 5 pounds per cubic foot. When the final density lies between 0À5 and 5 pounds per cubic foot an additional compression is applied to the body at rightangles to the first compression, i.e. transverse the rows, the combined compression ratio lying between 3À5 to 8. A set of conveyers 16, 18 extending across the mould guides one row of vertical fibrous elements at a time into the mould space, via a roll 12, and when a desired length of element has advanced into the space, the row is cut by an assembly 20. The latter includes an angle iron (30), Fig. 3, not shown, and cutter (32) and a member (34) with combs (36). The mould may have a corrugated bottom to prevent the elements slipping and devices to retain them upright during their packing. After compressing the elements into a block the filled mould may be immersed in a resinous binder and then drained and heated in an oven to cure or solidify the binder which may be thermosetting or thermoplastic. Each element may comprise a sliver of crimped fibres which may be of thermosetting or thermoplastic synthetic resins, of which many examples are given. Composite fibres or filaments may be used in the slivers, e.g. a sheath of polyamide around a polyester core. Blends of two or more fibres including natural fibres such as cotton, wool &c. may be used in the slivers; the latter may be identical or have different colours, weights &c. A thermosetting or thermoplastic binder, of which many examples are given, may be applied to the fibres, e.g. by dipping, spraying &c., before they are fed to the mould. Alternatively, for binding the fibres together, fibre solvents or high frequency heating may be used. Each sliver may be rolled from a web of fibre, and sheet material obtained from the porous block by cutting the block perpendicularly to the lengths of the fibres.
