Appl. No.:

08/853425

Inventors:

David W. Conway - Mason OH

Assignee:

Standard Textile Co., Inc. - Cincinnati OH

International Classification:

B32B 704

Abstract:

An absorbent barrier sheet ( ) includes an integral fabric web ( ) and a vinyl barrier material ( ) intimately connected to and across the integral fabric web ( ). The web ( ) includes an upper portion ( ) and a lower portion ( ), with the upper portion including a plurality of hydrophobic first yams ( ) and the lower portion including a plurality of fluid-retaining second yams ( ). In addition, the web ( ) has a middle portion ( ) which includes a set of ground yarns ( ) and parts of the hydrophobic and fluid-retaining yarns ( ),( ), with the ground yarns ( ) integrating the hydrophobic and fluid-retaining yarns ( ), ( ) of the upper and lower portions ( ), ( ), thereby forming the integral fabric web ( ). The vinyl barrier material ( ) is intimately connected to and across the fluid-retaining lower portion ( ) of the integral fabric web ( ). In this fashion, fluid at the top of the absorbent barrier sheet ( ) tends to wick downward towards the fluid-retaining portion ( ), whereby the top of the sheet tends towards dry.

Abstract:

An infant T-shirt (10) is provided with an improved crotch panel (14) having an absorbent layer (50) and a barrier layer (52) to retain fluids. The absorbent layer (50) may have an upper hydrophobic surface (54) and a lower hydrophilic surface (56). The barrier layer (52) may have a fluid barrier ply (60) and a fabric ply (62) to support the fluid barrier ply (60). The fabric ply (62) may define the outer surface of the crotch panel (14). Alternatively, an extension (80) of the T-shirt material may define that outer surface with the barrier layer (52) overlying the extension (80).

Intellitecs International, Inc. - Mason OH

International Classification:

B32B 302

US Classification:

428 89

Abstract:

One embodiment of the fabric (10) of the present invention includes an upper portion (12), middle portion (20) and lower portion (14), with the upper portion (12) having raised surface construction hydrophobic first yarns (16), the lower portion having hydrophilic (18) second yarns and the middle portion (20) being a region in which ground yarns (22), hydrophobic first yarns (16) and hydrophilic second yarns (18) are integrated. The upper portion (12) further includes at least one channel (24), which is a region free of raised surface construction hydrophobic first yarns (16). The channel (24) facilitates transmission of fluid from the fabric upper portion (12) to the lower portion (14) by exposing a part of the lower portion hydrophilic second yarns (18) which extends into the middle portion (20) directly to fluid on the upper portion (12), thereby enabling the fluid to contact and be absorbed by a hydrophilic second yarn (18) without first having to wick along a raised surface construction hydrophobic first yarn (16). In a preferred embodiment, several adjacent channels (24) are aligned to form elongated channels (24) which intersect one another in a grid-like fashion. The fabric may be incorporated into undergarments, suitable examples of which include an infant T-shirt (52), a woman's panty (62) and a man's brief (70).

Abstract:

A system for tracking costs of medical procedures by monitoring the movements of personnel, supplies and equipment and processing data on these movements to produce detailed and accurate cost accounting records associated with particular services rendered. Transponder tags are associated with each person and object for which costs are to be tracked. The detected movements of the tags are combined with scheduling, procedure and cost information to build detailed records of activities and the costs thereof in a manner permitting a wide variety of statistical and other analyses.

US Classification:

Abstract:

A quick-attach absorbent pad 14 for use with a panty 10 is provided with an upper surface 16 and a lower surface 18, the pad 14 being sized to fit against a crotch panel 12 of a panty 10 with the lower surface 18 of the pad 14 adjacent the crotch panel 12. The pad 14 further includes a plurality of hook fasteners 20 associated with the pad lower surface 18, which enables the pad 14 to be readily attached to the undergarment 10, and which prevents the pad 14 from shifting during use. Also provided is a panty 10 having a thin yet absorbent crotch panel 12. In a preferred embodiment of the panty 10, the crotch panel 12 includes a fluid absorbent layer 38 overlying a fluid barrier 40. The fluid absorbent layer 38 preferably is made of a single-ply fabric having a hydrophobic upper surface 42 facing toward the user and a hydrophilic lower surface 44 facing away from the user. In addition, the upper surface 42 preferably includes yarn loops 90 which releasably hold to the hook fasteners 20 on the absorbent pad 14, thereby maintaining the pad 14 in position on the undergarment 10.
