FIELD: medical engineering.
SUBSTANCE: method involves boiling reinforcing fabric in mixture of 10% aqueous solution of detergent powder Lotus or others, 5% aqueous solution of KOH or NaOH alkali during 45-60 min with following neutralization, removing saponated fats, activating superficial threads with 10% aqueous solution of oxalic acid, washing in running water and drying the reinforcing fabric at 25-60°C to reach humidity of 1.5-2.5%.
EFFECT: improved adhesive-cohesive reinforcing fabric properties; avoided delamination; high strength; reduced article weight.
