This invention relates to water responsive thermoplastic compositions and articles constructed thereof. This invention particularly relates to thermoplastic copolyester compositions useful for the manufacture of disposable-articles such as disposable diapers and feminine napkins. More particularly, this invention relates to thermoplastic copolyester compositions that are useful as a raw material in the manufacture of nonwovens, barrier films or coatings and as well as for various improved hot melt adhesives compositions useful for incorporating hydrophilic features into disposable articles.

Non-woven application for water dispersable copolyester

This invention relates to water responsive thermoplastic compositions and articles constructed thereof. This invention particularly relates to thermoplastic copolyester compositions useful for the manufacture of disposable articles such as disposable diapers and feminine napkins. More particularly, this invention relates to thermoplastic copolyester compositions that are useful as a raw material in the manufacture of nonwovens, barrier films or coatings and as well as for various improved hot melt adhesives compositions useful for incorporating hydrophilic features into disposable articles.

A method of packaging thermoplastic hot melt adhesive compositions in a continuous process. The process is especially suited for hot melt pressure sensitive adhesives to provide convenient handling of such. The process includes the steps of: dispensing a thermoplastic composition into a hollow sleeve of thermoplastic film, wherein said film is submerged in a heat sink bath; sealing the molten thermoplastic composition filled composition; allowing the molten thermoplastic composition to cool and solidify while submerged in the heat sink bath. An apparatus for practicing the process includes: a means for providing a hollow sleeve of thermoplastic film; a dispensing means for filling said hollow sleeve of thermoplastic film with a thermoplastic composition; a heat sink bath adjacent to said dispensing means such that the hollow sleeve of thermoplastic film is submerged in said heat sink bath while being filled; and a means for conveying the filled sleeve of thermoplastic film beneath the surface of the heat sink bath until said filled sleeve has substantially solidified.
