The present invention provides tissue webs and products having improved z-directional properties. The improved z-directional properties may be achieved by providing the structure with a unique three-dimensional surface topography, which increases the structure's Exponential Compression Modulus (K) and Caliper Under Load (C0). By improving both K and C0, the present inventors have also been able to provide tissue structures with relatively high Compression Energy (E), which enables the structures to be calendered at high loads without significant loss of sheet bulk or degradation of strength.

The present invention relates to a device for protecting paper sheet, including the following. A mist treating system, includes a working cover and a suction port provided on the working cover. A metal base plate is capable of being drawn out from an outlet of the working cover. An inlet and an outlet are provided on the sidewall of the working cover. An insulating layer provided at the top surface of the metal base plate. A sliding rail is provided above the metal base plate. A sprayer is used for applying an atomized deacidification agent to a paper sheet. A discharging electrode is used for discharging to the paper sheet on the insulating layer. The working cover is covered outside of the metal base plate, the insulating layer, the sliding rail, the sprayer, and the discharging electrode. A plasma power supply is used for generating linear plasma.

A pollen paper formed from a plurality of pollen microgels, which paper is dimensionally locked for use in the generation of conventional printed matter. It is possible to remove the printed subject matter from the pollen paper by a process that involves immersing the pollen paper into an alkaline bath, then removing the water through immersing it in a dehydrating bath and finally dimensionally locking the paper by immersing it in an acidic bath.

Disclosed herein is a hygromorphic composite material comprising a moisture-active pollen paper substrate formed from a plurality of pollen microgel particles, and at least one moisture-inactive layer applied onto the top and/or bottom surface of the moisture-active pollen paper substrate with a pattern that causes the hygromorphic composite material to change its shape in a pre-determined manner due to a change in relative humidity of its ambient environment. Also disclosed herein is a method of forming the hygromorphic composite material.

The invention relates to a thermal sublimation paper which can be printed with inks containing a sublimatable dye, in particular ink-jet inks, in which paper a hydrophilic thermal transfer layer to be printed is formed on a porous base paper. Thermoplastic particles with an average particle size of between 0.3 and 5 m and a melting point of between 35 C. and 190 C. are present in the thermal transfer layer. This thermal sublimation paper can be advantageously produced as follows: an aqueous coating slip is applied to a porous base paper having a Cobb value of between 55 and 150 g/m.sup.2, in particular between 70 and 150 g/m.sup.2, in a paper-making or coating machine, online or offline, said aqueous coating slip containing thermoplastic particles and constituents suitable for forming a hydrophilic thermal transfer layer, and a drying step is subsequently carried out in order to obtain the thermal sublimation paper. The thermal sublimation paper can be used advantageously to print flat materials, in particular films and textiles.
