Friction transmission belt and method for producing same

A frictional power transmission belt includes a tension layer forming a belt back surface, a compression rubber layer to be in contact with a pulley and frictionally engaged with the pulley, and a tension member embedded between the tension layer and the compression rubber layer along a belt length direction. The compression rubber layer has a surface to be in contact with the pulley. At least a part of the surface is coated with a fiber layer via a fiber/resin mixture layer. The fiber/resin mixture layer contains a resin component and heat-resistant fibers having a softening point or a melting point higher than a vulcanization temperature of a rubber forming the compression rubber layer. The fiber layer contains hydrophilic heat-resistant fibers having a softening point or a melting point higher than the vulcanization temperature and does not contain a resin component.

11192987 · 2021-12-07 · ·

The present invention relates to a new process for improving runnability and dimensional stability when manufacturing a film comprising high amounts of microfibrillated cellulose (MFC) without negatively impacting the film properties. According to the present invention a high amount of nanoparticles is used as an additive, optionally together with a retention polymer.

Air and water barrier article including inelastic porous layer

The air and water barrier article includes a polymer-coated inelastic porous layer including a water-vapor permeable polymeric coating disposed on at least one major surface of the inelastic porous layer and an adhesive disposed on a major surface of the polymer-coated inelastic porous layer. The inelastic porous layer can include at least one of surface-modified fibers or natural cellulose fibers. The polymer-coated inelastic porous layer can at least one of a water strike through time of not more than 180 seconds or an absorbance capacity of at least one-half gram per 116 square centimeters. The adhesive may be exposed, in contact with a release surface, or adhered to a surface of a building component. A method of applying the air and water barrier article to a surface of a building component is also disclosed.

Pad of dispensable tape segments
11358822 · 2022-06-14 ·

A pad of dispensable adhesive tape segments is shown and described. The pad includes a protective envelope and a number of tape segments. The tape segments are arrayed such that detachable pull tabs for each are exposed for grasp. The envelope may include a strip folded over onto itself and adhered in place. The envelope is pulled open and may be adhered to an environmental surface. Tape segments have adhesive of weaker adherence than the adhesive of the envelope so that when pulled by a pull tab, each tape segment preferentially releases from the next, but the envelope maintains adherence to the environmental surface. Adhesive lined tabs initially holding the envelope closed may also be used for adherence to the environmental surface. Preferably used for medical tape, the envelope is waterproof to maintain sterility of tape segments.
