摘要:
A fabric is treated by applying a nanoparticle type coating to improve their resistance to contamination by foreign matter. The coating is applied during fabric manufacture and cured during heat setting. Alternatively, the coating applied or renewed by utilizing an existing shower or locating a spray boom or other suitable coating application device to apply the coating to the fabric in a controlled, uniform manner. Prior to application of the coating, the fabric is first thoroughly cleaned such as by showering or spraying, and then dried. Following controlled application of the coating, any excess material is removed by a suitable means, such as by vacuum, and the remaining coating on the fabric is then cured, either by utilizing the ambient heat of the equipment or by a portable bank of heaters. In this manner, the fabric does not have to be removed from the machine in order to apply or renew the contaminant resistant coating.

The invention concerns a textile product (6) for use in a paper machine, having a monofilament or a profiled structure as support element (1) on which is arranged a layered sensor for measuring pressure and/or temperature, and is characterized in that the sensor is constituted from at least three layers (2, 3, 4), the second layer (3) having piezoelectric properties and the layers (2, 4) in contact against the second layer (3) forming electrodes that are couplable or coupled to an analysis device.The invention further concerns a method for producing such a textile product.
摘要:
Composition and methods for inhibiting the deposition of organic contaminants from pulp in pulp and papermaking systems are disclosed. The methods add to the pulp or to the deposition prone surface of the papermaking system a composition comprising a polyvinyl alcohol having 50 to 100% hydrolysis, a high molecular weight gelatin having a molecular weight of about 100,000 or higher, and a cationic polymer.
摘要:
Compositions and methods for inhibiting the deposition of organic contaminants from pulp in pulp and papermaking systems are disclosed. The methods add to the pulp or to the deposition prone surface of the papermaking systems a composition comprising a dinonyl sulfosuccinate anionic surfactant which is used in systems containing multivalent cations, preferably calcium ions. The methods also utilize a blend of dioctyl sulfosuccinate and didecyl sulfosuccinate anionic surfactants.

Paper-making, pulp-dewatering wires or webs are now made of a woven fabric of synthetic resin filaments. Such a fabric is often accidentally perforated. A patch of similar fabric is placed on the perforation and secured to the wire by means of a series of staples. The patch is circular and the legs of the staples are radially directed. The patch is positioned on the paper-contacting face of the wire and the bight of the staples does not protrude from the underside of the wire. An apparatus is disclosed for the insertion of the staples through the wire and the patch.

The invention relates to a cloth for a paper machine, comprising a fabric formed of threads of a synthetic material. In the cloth, reinforcements extending substantially longitudinally of the cloth are positioned at predetermined points. The reinforcements are formed be feeding molten plastic material in a narrow stripe on to the surface of the cloth. In order to improve the wear properties of the wire, the directions of the stripes forming the reinforcement are arranged to deviate locally from the longitudinal direction of the cloth.

A sheet forming fabric with reinforced margins is provided on its backing side with a fabric strip in the marginal regions. The fabric strip can have a double layer structure with transverse threads arranged at least partially in pairs one over the other and with longitudinal threads. The fabric strip has a pronounced longitudinal filament structure on the backing side and is fastened to the fabric by stitching. The sewing thread takes the place of a longitudinal thread of the fabric strip previously removed from or omitted during weaving of the fabric.
摘要:
Apparatus for processing paper wherein a pair of endless curved wire devices operate to pass therebetween a sheet material to be treated for a dewatering operation or the like. A support structure in the form of individual support segments made from sintered oxide ceramics are arranged to extend over the width of the apparatus and are in contact with one another, with a plurality of the segments being arranged consecutively in the direction of the course of the wire devices, the segments having a maximum linear expanse of 700 mm per segment and having junction areas between consecutively arranged segments defining a gap for feeding cooling water to the guide wire devices.
