This invention relates to a nonwoven web comprising a water soluble polyamide and articles constructed therefrom. The water soluble polyamide may be used alone or in combination with conventional thermoplastic web forming materials such as water insoluble polyethylene, polypropylene, polyester and polyamide. The water soluble polyamide may also be combined with biodegradable or selectively dispersible material to form nonwoven webs having various combinations of properties. Such water soluble webs have utility in the manufacture of disposable absorbent articles such as disposable diapers, feminine napkins, incontinent products and cellulosic articles such as tissues and towels, as well as for water soluble heat fusible webs for the textile industry.
A nonwoven web comprising a water soluble polyether amide produced by reacting at least one polyalkylene glycol diamine with at least one dicarboxylic acid or ester thereof, said polyalkylene glycol diamine has the formula:
A cellulosic absorbent having improved strength comprising a water soluble polyamide.
A flushable, disposable article comprising a nonwoven web having portions of at least one water soluble polyamide and portions of a water insoluble polymer in contact with each other.
