Sterilisable fabric for medical uses - comprises wash-proof combination of absorbent fabric bonded to polyurethane membrane reinforced with light synthetic knitted material

摘要

A sterilisable material which is resistant to boiling water consists of an absorbent layer on an elastic membrane which is not microporous but which, although impervious to water, allows water vapour to pass through, and this membrane is covered with a light fabric. The absorbent layer is pref. cotton fabric or a mixed fabric contg.-viscose; the membrane is pref. polyurethane covered with polyamide or polyethersulphone knitted fabric. Pref. a cotton or cotton/polyethersulphone fabric of substance 120-180 g/m2 is glued at points to a polyurethane membrane which is permeable to water vapour. The membrane is reinforced with 35g/m2 polyethersulphone knitted material and is produced by a transfer process; its thickness is 50 microns. The polyurethane membrane in an example was produced with 'Impraperm 43174' for cover and 'Impraperm 43176' (both R.T.N.) adhesive layer. The absorbent material can also be a non-woven product of adequate mechanical strength. -. ADVANTAGE - The prods. are particularly suitable for use in the medical field. They can be washed and sterilised. They are comfortable to wear.
