ABSTRACT:
This invention is directed to formation of a creped nonwoven web. The creped web is formed in a creping process using a polymer emulsion binder formed in an alkylphenol ethoxylate-free surfactant system. The surfactant system comprises a combination of a specific active anionic surfactant (sodium laureth sulfate containing 1 to 12 moles of ethylene oxide) and a specific active nonionic surfactant (a secondary alcohol ethoxylate containing 7 to 30 moles of ethylene oxide or an ethoxylated branched primary alcohol containing 3 to 30 moles of ethylene oxide.)
