Filed:

Nov 28, 2000

Appl. No.:

09/723698

Inventors:

Mark Stephen Edwards - Hockessin DE
Jeffrey Allen Chambers - Hockessin DE
Wayne Hugh Marshall - Wilmington DE
Roberto Bucker - Hockessin DE
James Harmon Watts - Wilmington DE
Susan Elaine Loudin - Landenberg PA

Assignee:

E. I. du Pont de Nemours and Company - Wilmington DE

International Classification:

A46B 904

US Classification:

151591, 15206

Abstract:

Several brush assemblies are disclosed. All employ bristle strings that include a base string connected to a plurality of monofilaments. The preferred monofilaments are nylons and other polymeric thermoplastic materials. The monofilaments may be linear segments or loop segments disposed in two rows. The bristle strings may be connected to brush bodies to form virtually any of the various types of brushes. Bristle strings employing loops may be braided together to form entangled, monofilament articles for brush or other applications.

International Classification:

B65H 8100

US Classification:

156174, 156 72, 156173, 156175, 428 95

Abstract:

Methods and apparatus for making elongated articles are disclosed. One method includes feeding at least one base string along an axis, wrapping at least one monofilament around the axis to produce a number of monofilament wraps per length of base string which are transported by the base string, bonding the wraps to the base string with ultrasonic energy, and cutting the wraps at a point downstream of where the wraps are bonded to the base string. The result is an article having two rows of monofilament segments connected to the base string.

International Classification:

A47C 3100

US Classification:

2972281, 442182

Abstract:

Upholstery stretch slipcovers are constructed from fabric having sufficient elastic recovery force so that the covers require no additional fabric to hold the slipcovers in place or to maintain a substantial absence of wrinkles in the slipcovers. The stretch slipcovers are particularly useful for chairs having separate back and seat cushions.

International Classification:

B32B 31/00

US Classification:

156 84, 156160, 156161, 156164, 156229

Abstract:

A multi-layer composite sheet comprising a shrinkable layer intermittently bonded a to a gatherable layer with the bonds separated by a specified distance and wherein the shrinkable layer can shrink and at the same time gather the gatherable layer between the bonds. A process for preparing multi-layer composite sheets by intermittently bonding a shrinkable layer to a gatherable layer with the bonds separated by a specified distance and causing the shrinkable layer to shrink while at the same time gathering the gatherable layer between the bonds. Preferably, the shrinkable layer comprises an array of fibers or nonwoven web comprising fibers having latent spiral crimp.

US Classification:

428/092000

Abstract:

A bristle sub-assembly includes first and second base strings and a plurality of polymeric monofilaments connected to and extending between the first and second base strings. The polymeric monofilaments form a first arched row when the first and second base strings are brought together. Several types and configurations of brushes are made using either arched bristles or combinations of arched and straight bristles.
