Abstract

Spunlaced nonwovens for medical use were finished for blood repellency, moisture transpiration, water resistance and abrasion resistance with fluorochemicals and polyrethane foam coating agent utilizing foam finishing technology(yen) and conventional padding application techniques. We could know that foaming efficiency of fluorochemicals was better as the order of FC-232> AG-730> Z-6700> AG-310) EM-11) AG-468> 519Z. Excellent water-oil-saline-alcohol repellency values, suitable water impact penetration values and water vapour permeability values were obtained with both techniques but showed low water entry pressure values for water resistance. The abrasion resistance properties of foam finishing spunlaced nonwovens were superior to those of the same spunlaced nonwovens finished conventionally.
