GLOVE AND METHOD FOR MANUFACTURING GLOVE
An object of the present invention is to provide a glove in which a glove main body and a film are less likely to peel from each other even when a load, especially a torsional load, is applied. A glove according to an aspect of the present invention includes: a glove main body made of fibers; a film which covers at least a part of an outer face of the glove main body and contains a rubber or a resin as a principal component; and an adhesive portion which bonds the glove main body and the film together, wherein the adhesive portion includes: a pressure-sensitive adhesive layer in contact with the film; and an adhesive layer which is in contact with the glove main body and is constituted by a hot-melt adhesive.
Expansible Barrier Film Assemblies
A barrier layer assembly is useful as a barrier component in articles subjected to repeated deformations. The barrier layer assembly has a support layer and a film layer. The barrier layer assembly has a bi-directionally corrugated surface. The surface may be an external or internal surface and is defined by non-sulcate furrows.
Pneumatic fender
Reinforcing layers each have a cord angle set to 25° or greater and 45° or less when a body is in a neutral state. When the body is loaded with a specified internal pressure, intermediate rubber layers disposed between adjacent sets in which cords of the reinforcing layers extend in an intersecting direction are shear-deformed, the cord angle increases approximately to a stable angle of repose, and the expanded body maintains a predetermined shape. In each of the sets being formed of two reinforcing layers layered adjacently, the cords of the reinforcing layers extend in an identical direction at the predetermined cord angle. Since substantially no shear force acts on the intermediate rubber layers disposed between the reinforcing layers, the resistance when expanding the body decreases. This provides a pneumatic fender that expands more smoothly and ensures a predetermined shape when a body is loaded with a specified internal pressure.

Method and system for forming a self-sealing volume using a breather system
A fabric and elastomeric material (referred to as a fabric trilayer) combined with a sealant may be applied in such a fashion so as to eliminate or minimize air entrapment in an elastomeric composite structure that forms a seal-sealing volume. The performance of the self-sealing volume is dramatically improved with this minimizing of air entrapment. Surprisingly and unexpectedly, this construction approach may be accomplished without significantly adding to the weight or thickness of the volume and without affecting the outer dimension of the self-sealing volume. Thus, a method and system for forming a self-sealing volume are described. The system includes an elastomeric composite structure comprising at least one layer of an elastomeric material derived from a neat (no solvent) elastomeric material that does not substantially react at room temperature.
