Claims11
An article comprising one or more sections of waterproof or water-resilient fabric, wherein each waterproof or water-resilient section comprises a film of dried aqueous polyurethane dispersion comprising a water-repellant and a prepolymer, the prepolymer comprising:
- a glycol,
- an aliphatic diisocyanate and
- a diol,
- wherein a ratio of isocyanate groups in the aliphatic diisocyanate to hydroxy groups in the glycol and the diol (NCO/OH) is about 1.30 to about 2.20 and wherein a concentration range of carboxylic acid groups in milliequivalent per kg of prepolymer (Meq Acid/kg CG) is about 140 to about 250.
