Patent number: 9340921Abstract: A process for manufacturing robust, flexible sheet-like material, includes the steps of a) applying a waxy composition to the web to form a waxed web; b) leading the waxed web via at least one roller to a chiller; c) cooling the waxed web; and d) leading the waxed web to a collection station for collecting the waxed web for further processing. The waxy composition comprises about 10-60 wt-% of a waxy compound and about 90-40 wt-% of a diluent. The waxy compound is selected from the group consisting of A) monoesters of a polyhydric aliphatic alcohol and a fatty acid; B) diesters of a polyhydric aliphatic alcohol and a fatty acid; and C) mixtures of said monoesters and diesters. The coating forms a stable liquid mixture at a temperature between about 35° C. and about 100° C., has a liquefaction temperature of at least about 30° C., and has a contact angle with a flat surface of the substrate of less than about 35° when measured at a temperature of 60° C.Type: GrantFiled: November 19, 2009Date of Patent: May 17, 2016Assignee: Johnson & Johnson Consumer Inc.Inventors: Paul Y. Fung, David Gubernick, Stephan M. Linkel, Ching-Yun M. Yang

Patent number: 5997986Abstract: Apertured plastic films comprise a stretchable thermoplastic polymeric material having a plurality of micro-holes defined by a network of fiber-like elements. The films are produced by directing fluids, especially water, against the upper surface of a starting film in the form of columnar streams in a contact zone, while the film is supported on a backing element. The films of the invention are useful as covering materials for absorbent products such as diapers, wound dressings and sanitary napkins.Type: GrantFiled: December 11, 1996Date of Patent: December 7, 1999Assignee: ChicopeeInventors: Mordechai Turi, Edmund Z.

Patent number: 4657804Abstract: A water-impervious, smooth-surfaced, gas-permeable, bacterial barrier, repellent treated, laminated material is described. A preferred embodiment comprises a ply of hydrophobic microfine fibers fuse bonded to a layer of conjugate fibers having a low melting sheath and a high melting core. The ply of hydrophobic microfine fibers is low melting. The sheaths of the conjugate fibers have been fuse bonded to the hydrophobic microfine fibers at a temperature below the melt temperature of the cores of the conjugate fibers so that the cores retain their initial fiber-like integrity. The laminated material is preferably impregnated with both a repellent binder and a repellent finish to secure good repellency, lamination and peelability.Type: GrantFiled: August 15, 1985Date of Patent: April 14, 1987Assignee: ChicopeeInventors: Alfred T.
