Latex containing odor inhibitors |
(57) A nonwoven fabric repellent to body fluids and having reduced odor on sterilization
by irradiation or steam is made by bonding nonwoven fibers with a latex, forming said
nonwoven fabric, and sterilizing said fabric, said latex is prepared by polymerizing,
in the presence of 0.1 to 2 weight parts of a free radical initiator and a sufficient
amount of a nonionic or anionic emulsifier, 65 to 85 weight parts of a soft hydrophobic
monomer having Tg of -80°C to -20°C, 10 to 30 weight parts of a hard hydrophobic monomer
having Tg of +40°C to +120°C, 0.1 to 5 weight parts of an unsaturated carboxylic acid
containing 3 to 6 carbon atoms, and 0.1 to 5 weight parts of N-alkylol acrylamide
or methacrylamide containing 1 to 10 carbon atoms, said latex has post-added and admixed
therein 0.01 to 5 weight parts of an odor inhibition agent selected from amine-type
antioxidants and hindered phenols that function to reduce odor of said fabric on sterilization
thereof.
