These are the 4 main tests used to rate the repellency of textiles.
Water Repellency Test - measures the ability of a fabric to hold out liquids. W is water and the easiest to hold out, 10 is the most difficult. Typically, new gowns are 5-6.
Oil Repellency Test - measures the fabric's ability to repel oil & oil-based fluids. The higher the rating the better able the fabric is at holding out oily substances. New gowns would generally be about 5.
Spray Test - measures the resistance of a fabric to wetting by water. A rating of 0 is poor and 100 is the best, new gowns are typically 90-100.
Suter Test - shows how well the fabric will hold out water under pressure. A rating of 0 is poor and 100 is excellent. A new single-ply 100% polyester grow would have a rating of 45-50 |
