摘要:
A fabric for use in filters separating water from a water/diesel emulsion, and a method of using such a fabric, where the fabric has a rectangular mesh, the sides of which are formed by respective threads. In comparison with prior art fabrics for water/diesel filters, the fabric of the invention offers the advantage of having a higher separation efficiency, thus allowing separation of diesel with a lower residual water content downstream of the filter.
摘要:
A composite ballistics protective textile structure comprises at least a textile element and one or more textile or thermoplastic matrix elements. The first textile element comprises unidirectional yarn fibers or flat strips. The second textile element comprises flat strip elements consisting of unidirectional yarns or thermoplastic films. Additional elements comprise thermoplastic matrix arrangements, based on rubber, elastomeric polymers or being laminated with thermoplastic films, for stabilizing the structure and reducing bullet trauma impacts.
摘要:
A novel multiple orientation construction for the ballistic protection, the process for making it and the main ballistic results obtained thereby. Said construction comprises at least a textile element and one or more thermoplastic or thermosetting based elements. The first textile element (1) comprises textile fibers. The second element (2) may comprise thermoplastic, thermosetting, rubber or polymeric elastomer based matrix arrangements or thermoplastic films for adjusting the textile construction characteristics according to the intended applications and for assisting in reducing bullet impact damages. The above elements jointly cooperate in absorbing and spreading a bullet impact stress.
摘要:
An acoustically transparent protector for an audio device provided with a sound generating transducer having a sound port covered by said protector for use with a human ear for the reproduction of sound which allows sound to pass through with little attenuation or distortion but does not allow foreign material such as ear wax, dust, debris, or water to pass into the sound port. The protector of the invention is provided with a sound radiating element having at least a curve portion and a suspension part. The protector of the invention realizes a “perfect” barrier that attenuates the sound entering the audio device as little as possible and does not suffer from significant sound distortions.
摘要:
A laminated double-layer textile product comprises a square mesh ferromagnetic alloy metal filament or thread technical fabric layer coupled to a square mesh synthetic monofilament technical fabric layer by laminating to provide a diffused joining of said two layers, said laminating comprising a hot-melt laminating.
摘要:
Structure for the ballistic protection of vehicles in general, characterized in that it comprises at least a first textile element and at least an additional element formed of a thermoplastic or thermosetting matrix. The structure forms a ballistic system for light armor plating obtained from at least one textile element and one or more thermoplastic or thermosetting base elements. The first textile element includes textile fibers. The second element can include thermoplastic matrices, thermosetting matrices, matrices based on rubber, elastomeric polymers and thermoplastic films of various kinds, the purpose of which consists in providing mechanical properties such that the use of the element can be extended to the field of armor plating while maintaining a high degree of flexibility. The aforesaid elements together contribute to define an efficient ballistic solution while maintaining a relatively low areal density.
摘要:
A composite multilayer filtering construction for use in filtering applications requiring a high filtering efficiency for particles of the order of microns and a high permeability of the filtering medium, and for use as a sub-component within acoustic and electronic products, in particular microphones and speakers, comprises at least a first layer of polymeric nanoporous membrane and at least a second layer of a synthetic monofilament precision fabric, the first polymeric nanoporous membrane layer being coupled to the second precision fabric layer thereby providing an integral filtering medium adapted to prevent a passage therethrough of particles even of 1-2 μm and of pressurized liquids.
摘要:
A fabric material composite construction, for use as a filter means or media, characterized in that said construction comprises a combination of one or more nanofiber layers and a synthetic single-thread squarely knitted precision fabric.
摘要:
A method for making, by a laser etching, a partially metallized single thread fabric material for aesthetic or marking applications, does not use polymers, inks, pastes and additives. The inventive method comprises a pre-metallizing step or a partial metallizing on the fabric and a following metal removal step, being performed by a quick and localized evaporation thereof, performed either on one or both the surfaces simultaneously, by a specifically designed laser.
