CONTROLLING FRICTION CHARACTERISTICS OF RESILIENT MEMBERS USING NEAR-SURFACE MICROSTRUCTURES

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.

The tape includes a first slit row including a plurality of slits formed intermittently along a longitudinal direction, and a second slit row including a plurality of slits formed intermittently along a longitudinal direction and parallel to the first slit row. A portion without having a slit formed in the first slit row is arranged so as not to overlap a portion without having a slit formed in the second slit row.

CARRIER WITH LOCALIZED FIBROUS INSERT AND METHODS
20230093318 · 2023-03-23 ·

A structural reinforcement for an article including a carrier that includes: (i) a mass of polymeric material having an outer surface; and (ii) at least one consolidated fibrous insert (14) having an outer surface and including at least one elongated fiber arrangement having a plurality of ordered fibers arranged in a predetermined manner. The fibrous insert is envisioned to adjoin the mass of the polymeric material in a predetermined location for carrying a predetermined load that is subjected upon the predetermined location (thereby effectively providing localized reinforcement to that predetermined location). The fibrous insert and the mass of polymeric material are of compatible materials, structures or both, for allowing the fibrous insert to be at least partially joined to the mass of the polymeric material. Disposed upon at least a portion of the carrier may be a mass of activatable material.

LABEL WITH EMBOSSED RELEASE LINER
20230086349 · 2023-03-23 ·

A label and liner assembly comprises one or more labels, the label(s) including a facestock and an adhesive layer on a surface of the facestock. A support liner is releasably adhered to the adhesive layer, the support liner defining a plurality of embossings projecting from a surface of the support liner toward or away from the label. A transfer tape and a method for assembling label material are also provided.

MANUFACTURING METHOD OF HALF-CUT DOUBLE-SIDED TAPE AND HALF-CUT DOUBLE-SIDED TAPE STICKING DEVICE
20220340788 · 2022-10-27 ·

To provide a half-cut double-sided tape from a double-sided tape with a release-liner commercially available in the market by means of a simple process without contacting a cutter blade directly to an adhesive layer when making the half cuts in the half-cut process. The invention includes: a processing protection layer formation step of feeding a protect release paper tape having the release surface to the double-sided tape to form a processing protection layer on the double-sided tape with the release liner; a half-cut step of continuously performing half-cut together with the processing protection layer and the double-sided tape on the release liner while leaving only the release liner, and making a number of the double-sided tape pieces of proper length are held on the release liner; a half-cut double-sided tape winding step of winding the half-cut double-sided tape with the release liner while peeling off the processing protection layer. A cut trace has a fully cut region in the width direction of the double-sided tape on the release liner and a non-cut region in the width direction of the protect release paper tape, so that the peeling is facilitated.

ULTRA-QUIET BACKING-PAPER-FREE COLD LAMINATING FILM AND PREPARATION METHOD THEREOF
20220340782 · 2022-10-27 ·

The present invention discloses an ultra-quiet backing-paper-free cold laminating film comprising a substrate layer, a release layer, and an adhesive layer, the release layer and the adhesive layer being each attached to a respective side of the substrate layer, the release layer being obtained by drying a release agent applied on the substrate layer, and the release agent consisting of the following components by weight: 2-ethylhexyl acrylate, vinyltrimethoxysilane, 1-methyl-1-phenylethyl hydroperoxide, vinyl-terminated silicone resin, di-t-butyl cumene peroxide, fluorosiloxane, ethyl acetate, ethylene glycol dimethyl ether, a toughening agent, polysiloxane-polyether copolymer, silicone and wax powder. In the invention, the peel strength is reduced; it is ensured that the release force of the cold laminating film is not affected by the external environment, such that the cold laminating film has good stability; and meanwhile the subsequent adhesion of the release layer is improved, so that it can ensure that the adhesive force of the adhesive layer would not be affected after long-term adhesion between the adhesive layer and the release layer.

Photosensitive medical tape

A photosensitive medical tape includes a backing layer that is at least partially transparent to a first spectrum of electromagnetic radiation. The photosensitive medical tape also includes a coupling layer disposed on a first side of the backing layer to provide adhesion of the photosensitive medical tape to the human skin. The photosensitive medical tape is disposed to absorb a second spectrum of electromagnetic radiation to decrease a strength of the adhesion provided by the coupling layer. The photosensitive medical tape is also flexible.
