Abstract: An insulating paperboard contains at least one layer of cellulose fibers. The one layer is at least partially composed of bulky fibers. The paperboard is sufficiently insulated to provide a hot water nullT across the paperboard of at least 0.7null C.null2.3null C. per 0.1 mm of caliper. The paperboard may be embossed to decrease surface transmission of heat. A hot cup may be produced from the insulating paperboard.

Abstract: In accordance with the present invention, lyocell products can be made with unbleached pulps resulting in products with high amounts of hemicellulose and high amounts of lignin as compared to conventional lyocell products. The lyocell products of the present invention are advantageously less expensive to produce but retain the desirable strength of conventional lyocell products.
