Creeping on fabric and fabric drying process for manufacturing adsorbing paper cloth

FIELD: paper. SUBSTANCE: raw fibrous layer with chaotic distribution of fibres is formed and moved to the transporting transmitting surface. Fibrous layer is dried till dryness is 30% to 60%, including de-watering with sealing of fibrous layer prior to its being moved to the transmitting surface or simultaneously with it. Fibrous layer is crept on fabric with the creeping pattern surface. Fabric creeping is performed under pressure with the movement at the speed that is lower tan the speed of the transmitting surface. At that, the fabric pattern, contact zone parametres, speed difference and dryness of fibrous layer are chosen so that the fibrous layer can be crept from the transmitting surface and redistributed on the creeping fabric thus forming fibrous layer with elastic net structure with many fibre cluster areas, which are located in the form of the pattern corresponding to the pattern of the creeping fabric surface. Elastic net structure includes fibrous matrix the porosity whereof is increased as it is stretched. Fibrous layer is dried at its being maintained in the creeping fabric.

Tissue paper

Soft, absorbent paper webs and processes for making them. In the process, an aqueous dispersion of the papermaking fibers is formed into an embryonic web on a first foraminous member such as a Fourdinier wire. This embryonic web is associated with a second foraminous member known as a deflection member. The surface of the deflection member with which the embryonic web is associated has a macroscopic monoplanar, continuous, patterned network surface which defines within the deflection member a plurality of discrete, isolated deflection conduits. The papermaking fibers in the web are deflected into the deflection conduits and water is removed through the deflection conduits to form an intermediate web. Deflection begins no later than the time water removal through the deflection member begins. The intermediate web is dried and foreshortened as by creping. The paper web has a distinct continuous network region and a plurality of domes dispersed throughout the whole of the network region.

Method of creping tissue webs containing a softener using a closed creping pocket

The invention consists of soft, bulky tissue products that result from the presence of a debonder/softening agent in the outer layers of the tissue and creping under "closed" pocket conditions. The debonder/softening agents belong to a group of organic chemicals that include several imidazolinium quaternary compounds. These chemicals do not adversely interfere with adhesion, unlike most debonders, to the drying surface of the tissue machine. They can, therefore, be placed in the outer layers of the tissue that contact the dryer surface and improve creping. The tissue can then be creped off of the drying surface using a closed pocket, that is a pocket angle of less than 80 degrees. The closed pocket creping normally produces a thicker, less dense tissue but with coarse crepe. Closed pocket creping and the presence of most debonders in the dryer side layers would be expected to also produce coarse crepe structures. However, the interaction of debonder adhesive properties and the closed pocket creping conditions produces a bulky tissue with sufficiently fine crepe structure that results in high overall softness.

Compressed absorbent fibrous structures

The present invention provides compressed paper webs that maintain a substantial amount of their absorptive capacity and wet strength when compressed. The compressed webs bounce back to a portion of their uncompressed state when wetted. The present compressed webs allow more towels to be added to a dispenser without substantially sacrificing the absorbent capacity or the strength of the towels.

Crimped fibrous sheet for e.g. wall covering - by sheeting fibre-plastic powder dispersion, drying, heating and pressing

Crimped fibrous sheet, for e.g. wall covering, is produced by (a) forming an aq. dispersion of fibres, e.g. wood pulp, and thermoplastic polymer powder, e.g. polyethylene, (b) draining the dispersion on a porous support to produce a fibrous sheet material contg. dispersed polymer powder, (c) drying the material produced on the porous support, (d) heating the dry material, and (e) crimping by applying pressure while it is still hot, in order to form a relief surface. does not cause blurring of the relief surface when wetted.

Patent FR2031458A1

Process for increasing the softness of base webs and products made therefrom

A process for increasing the tactile properties of a base web without adversely effecting the strength of the web is disclosed. In one embodiment, the process includes the steps of placing a base web between a first moving conveyor (60) and a second moving conveyor (62). The conveyors are then wrapped around a shear-inducing roll (64) which creates shear forces that act upon the base web. The shear forces disrupt the web, increasing the softness and decreasing the stiffness of the web. The shear-inducing roll (64) typically has a relatively small diameter. In some applications, more than one shear-inducing roll may be incorporated into the system. Base webs made according to the present invention have been found to have improved void-volume and fuzz-on-edge properties.

Embossed paper having alternating high and low strain regions

ABSTRACT An embossed sanitary paper product and method of making such product. The paper is embossed to form in the paper a midplane and an array of bosses extending up and down from the formed midplane. Each upward extending boss is flanked on two sides, in each of two directions, by a downward extending boss, and in at least one of the two directions, the paper between an upward extending boss tip and an adjacent downward extending boss tip on one side has a higher strain than the paper between the upward extending boss tip and an adjacent downward extending boss tip on the opposite side. The forming of a higher strain region and a lower strain region on opposite sides of a boss can be accomplished by forming asymmetric bosses with each upward extending boss rotated 180° about an axis perpendicular to the plane of the paper with respect to its adjacent downward extending bosses.

Paper machinery

Method and system for producing wet-pressed, molded tissue products

A process for producing tissue webs is disclosed. The process may include the step of partially dewatering a tissue web, subjecting the web to at least one deflection against a fabric, such as a coarse fabric, and then creping the web. During the process, after being dewatered, the tissue web is transferred from a transfer conveyor to the fabric using a pneumatic force, such as a suction force. In order to prevent liquids from rewetting the tissue web as the tissue web is being transferred to the fabric, the transfer conveyor is made from a material that inhibits or prevents liquids from flowing into the tissue web. For instance, in one embodiment, the transfer conveyor may comprise a felt comprised of small capillary materials. The felt may have an intake rate, for instance, of less than about 150 ~L/s when wet, may have a mean free pore size of less than about 20 microns, and may have a minimum pore size of less than about 5 microns.
