Filed:

May 17, 2001

Appl. No.:

09/859699

Inventors:

Jeffrey L. Robbins - Phoenixville PA

Assignee:

Bayer Corporation - Pittsburgh PA

International Classification:

B05C 1102

US Classification:

118500, 118 33, 118641, 118 67, 118 68, 118126, 118413, 156 72

Abstract:

The present invention relates to an improved doctor blade and bedplate apparatus wherein there is a recess in the bedplate from some position upstream of the doctor blade to some position downstream of the doctor blade. This recess or gap in the area of the bedplate under the doctor blade allows one to form an even or uniform coating on the back of a web of material. This is particularly helpful in forming uniform coatings on the back of a greige good which has face fibers of varying lengths. The present invention also relates to an improved process for preparing a relatively uniform coating on the back of a web of material.

Abstract:

The present invention relates to an improved process for the production of artificial turf, and the improved artificial turf. In accordance with this process, fibers are treated via corona discharge, tufted into a primary backing to form a greige good, and a precoat is applied to the back surface the greige good. Suitable fibers are polyolefins, and suitable precoats are reactive polyurethane mixtures. The fibers may be treated by corona discharge either before they are tufted into the primary backing to form the greige good or after the are tufted into the primary backing. Artifical turfs of the present invention comprise a greige good having fibers tufted into a primary backing, with the fibers being treated by corona discharge either before or after being tufted into the primary backing, and a precoat which is attached by its face surface to the back surface of the greige good.

US Classification:

428/095000, 156/324000, 427/277000, 427/358000

Abstract:

This invention relates to a process for the production of patterned polyurethane foam as a backing for tufted goods. This process comprises applying a puddle of a reactive polyurethane mixture to the back side of a greige good, passing the greige good coated with the reactive polyurethane mixture under a doctoring device and curing the polyurethane backed greige good. In one embodiment of the present invention, the doctoring device is patterned or an attachment to the doctoring device is patterned, and forms a corresponding pattern in the polyurethane coating as it passes under the doctoring device. In another embodiment, a woven secondary backing is laminated to the reactive polyurethane mixture after passing under the doctoring device, and pressure is applied against the face of the tufted good such that the urethane is pushed through the windows of the secondary backing. This pressure forms beads of polyurethane on the underside of the woven secondary backing.

US Classification:

156 72

Abstract:

Tufted carpeting can be manufactured employing polyurethane adhesives and cured face up without dripping, when one or more drip-reducing process steps of adding a non-Newtonian thickener to the adhesive or forming a viscosified or cured film on the outer surface of the adhesive are practiced prior to entry of the greige good into the curing oven.
