Abstract

1,223,899. Moulding plastic substances. ROGERS CORP. 17 July, 1968, No. 34042/68. Headings B5A and B5N. [Also in Division B2] A microporous sheet of resin having an airpermeable coating on at least one face thereof is produced by applying a solution or dispersion of a resin in a liquid to a temporary backing sheet having a release surface; evaporating said liquid to provide on the release surface a thin air-impermeable layer of resin having a weight of from 0À1 to 2À0 gm./ft.<SP>2</SP>; placing the thin layer of resin backed by the backing sheet in contact with at least one face of a heated microporous sheet of resin and applying pressure to the backing sheet to cause the thin layer of resin to fuse to the microporous sheet and become airpermeable; after cooling, stripping the backing sheet from the thin layer of resin permanently fused to the microporous sheet. Alternatively a microporous sheet of resin having an air-permeable coating on at least one face thereof may be produced by spreading fine, granular thermoplastic resin in a uniform layer on a first resiliently compressible, fibrous sheet; placing over the exposed surface of the layer a second resiliently compressible, fibrous sheet, there being interposed between at least one of the fibrous sheets and the layer of granular thermoplastic resin a supported releasable thin air-impermeable film of resin having a weight of from 0À1 to 2À0 gm./ft.<SP>2</SP>; passing the resultant assembly between heated plates defining a passageway varying in thickness from a thickness at the entry of the passageway approximating the initial thickness of the assembly to a thickness less than the initial thickness at the exit of the passageway, the heated plates supplying heat and pressure to portions of the assembly passing therethrough to sinter the resin granules together into a microporous layer and to cause the releasable thin film of resin to fuse to the microporous layer and become air-permeable; and after cooling, stripping the thin film of resin film of resin fused to the microporous layer from its support. The thin film of resin may be releasably secured to one of the first and second compressible fibrous sheets, or to a separate supporting sheet interposed between one of the first and second compressible fibrous sheets and the layer of granular thermoplastic resin. Examples of thermoplastic resin are given.
