An improvement in the field of fabrics, wherein the fabrics provide improvements such as weighted regions (20) and grip locations (40). Currently, wearable weights are very limited in many ways such as, but not limited to, placement of the weights, fit of wearable weight to the user's body, sustained placement of the wearable weight during athletic use. The fabric (10) provides a solution to this problem by allowing the integrating the weights and other features into the material of any article of clothing or similar fabric object. The fabric (10) affords the user the comfort, flexible and other advantages typical of athletic clothing along with added benefits of weight training. Further, the grip locations (40) provide surface friction for athletic applications such as, but not limited to, fitness workouts and yoga. The principal use of the fabric (10) is as an article of clothing.

Methods of making bearings using pressure sensitive macromolecular adhesive polymers and pressure sensitive polymer compositions capable of integrating fluoropolymeric properties with a catechol-amine functionality to form an adhesive system that allows bonding between metallic substrates and fluoropolymers are disclosed. Also disclosed are core-shell polymeric particles comprised of a core and a shell comprising a thermoplastic polydopamine polymer that may be prepared as a colloidal suspension and used as a hot-melt pressure sensitive adhesive capable of binding low surface energy materials, such as polyolefins and fluoropolymers, to diverse materials including metals in making bearings and/or bearing components.

A bearing laminate can include a metal support layer, a foam layer overlying the metal support layer, the foam layer including a polymeric foam; and a sliding layer overlying the polymeric foam layer, the sliding layer comprising a polymer matrix. Bearing articles made from the bearing laminate can have exceptional damping properties, such as a high damping ratio combined with a low dynamic stiffness.

A method for manufacturing a sliding member according to one aspect of the present disclosure is a method for manufacturing a sliding member containing an ethylene-tetrafluoroethylene copolymer as a main component, and comprises processing a material containing an ethylene-tetrafluoroethylene copolymer as a main component, and irradiating a processed body obtained in the processing step with an electron beam.

Resilient members having near-surface architectures including microstructures for controlling friction are provided. A film-terminated array of fibrils having a sharp film/fibril juncture exhibits an unexpectedly large enhancement of adhesion, static friction and sliding friction. The enhancement is provided against rough indenters. A film-terminated array of elongated ridges and valleys unexpectedly exhibits low adhesion, and an unexpectedly large enhancement of sliding friction. The film-terminated ridge/valley design provides an anisotropic structure with direction-dependent frictional properties. The increase in sliding friction force varies as a function of interfibrillar spacing, and corresponds to a mode in which buckling of the terminal film occurs. The near surface architectures may be designed with varying scales and varying parameters to provide performance characteristics tailored to various applications. By way of example, the film-terminated ridge/valley array may be incorporated in motor vehicles tires to provide low rolling resistance and high sliding friction allow for high-performance braking during vehicle operation.

A polishing article includes a polishing layer having a working surface including at least one multi-cell structure disposed on the working surface. The multi-cell structure includes three cells, defined as a first cell, a second cell and a third cell. Each of the three cells includes at least one sidewall defining a cell shape. The first cell and the second cell include a first common sidewall including a first channel, having a first channel length, allowing fluid communication between the first cell and the second cell, and a first axis perpendicular to the first channel length and substantially parallel to the working surface. Further, the second cell and the third cell include a second common sidewall including a second channel, having a second channel length, allowing fluid communication between the second cell and the third cell, and a second axis perpendicular to the second channel length and substantially parallel to the working surface. An included angle between the first axis and the second axis is from 0° to less than 180°.

A system and method for a grinding disc, the grinding disc made out of three discs, capable of grinding in three positions such as the bottom, side, and top instead of only one position, the top disc and middle disc having an aperture such that a shaft having a washer and bar is connected to the discs by sliding the through the top disc whereby the washer is then received by the middle disc, the discs are then fastened together with the bar protruding from the discs whereby the bar may be connected to a tool such as drill, the grinding disc may then be used at multiple angles when connected to the tool

A high resolution elastomeric exterior laminate material includes an exterior polymeric film layer laminated to an ink graphic fabric layer. A method of making the high resolution elastomeric exterior laminate material includes providing an ink graphic fabric layer, providing an exterior polymeric film onto a first side of the an ink graphic fabric layer by one of a laminating, a molding, a rolling and an extrusion process to form a laminate.
