Methods of improving the drying rate of a cellulosic web, such as a tissue web, by providing an apparatus having two noncompressive dewatering devices, such as two through-air driers, where the temperature of the drying medium supplied to each device is separately controlled. The temperature of the medium supplied to the first device may exceed 450&#xb0; F., such as from about 450 to about 600&#xb0; F. On the other hand the temperature of the medium supplied to the second device may be less than the temperature supplied to the first, such as from about 350 to 450&#xb0; F. Drying the web in this manner not only improves drying efficiency, but also limits or prevents degradation of the web, such as the combustion of cellulosic fibers making up the web or monosaccharides associated therewith. As such, webs that are substantially free from furan and acetaldehyde may be produced by the present methods.

Through-air drying apparatus and methods of manufacture

The present invention provides a method of producing a decorative tissue product, while controlling tensile degradation in a predicable fashion. The foregoing properties may be achieved using differential depth embossing in conjunction with an embossing pattern having particular characteristics. The use of an engraved roll, such as an embossing roll, having protuberances of differing depths and patterns not only improves the properties and characteristics of the fibrous structure, but may also be used to impart a unique pattern that provides the product with a distinctive look and is appealing to consumers. Generally the unique pattern results from a first set of protuberances having a first height and defining a first pattern and a second set of embossing elements having a second height and defining a second pattern, where the first height is greater than the second height.
