| 摘要 |
The present invention relates to impermeable bed linen characterised by perspirant and flame-retardant properties, characterised by the fact that the linen items are obtained with pieces of fabric through the superimposition of one or more layers of perspirant and flame-retardant fabric (2, 20) and a layer consisting in a very thin micro-perforated hydrophilic membrane (3, 30), whose micro-perforations have a cross-section that allows for the passage of sweat melecules and prevents the passage of organic liquids.
