摘要:
Extruded net with at least some strands which melt away upon the application of heat while other strands maintain elastic, or other desirable properties. This netting is advantageously combined with a fabric in which the low melting strands function as an adhesive, while the high melting strands maintain their designed properties in the final laminate product.

A network article comprises reinforcing fiber fixed with a resin, in which the weft (3) is almost straight and, preferably, the warp (1,2) is also almost straight. To attain this, the warp consists of at least two kinds of yarns (1,2) having different rigidities, and the lower rigidity yarn (2) wreathes with higher rigidity yarn (1). Alternatively, a leno cloth is drawn in the weft direction to straighten the weft and then the resin is solidified under tension. The network article and a shaped inorganic product reinforced therewith exhibit higher tensile strength than those of the prior art.

The filter fabric containing polyphenylene sulfide fibers, characterized in that the following (1) and/or (2) is satisfied is used to provide a filter fabric and a bag filter composed of the filter fabric excellent in dust-collecting efficiency and high in mechanical strength: (1) Containing at least two webs, one of which on the dust side contains 50 wt% or more of heat resistant fibers with a fiber diameter of 15 µm or less, while the other web on the clean side contains 50 wt% or more of heat resistant fibers with a fiber diameter of 20 µm or more (2) Containing a web containing polyphenylene sulfide staple fibers with their fineness kept in a range from 1 to 3 dtex and fluorine-based staple fibers with their fineness kept in a range from 2 to 4 dtex.
摘要:
A carbon fiber-made reinforcing woven fabric comprising a carbon-fiber woven fabric formed from warps consisting of carbon fibers and wefts consisting of carbon fibers, and auxiliary yarns arranged along at least either warps or wefts, the auxiliary yarns being passed over and under other yarns differently from associated warps or wefts. When prepreg is produced by applying matrix resin to this woven fabric by a wet/prepreg processing method before drying, the presence of auxiliary yarns in gaps in the vicinities of warp-weft intersections on the woven fabric allows matrix resin to remain around auxiliary yarns to produce no apertures in the obtained prepreg, whereby the woven fabric is suitable for a prepreg production by wet/prepreg processing.
摘要:
A press felt for use in the press section of a papermaking machine. The felt is comprised of at least one base fabric to which at least one batt layer is attached by needling or another suitable method. A woven or nonwoven fibrous scrim may be included between the base fabric and the at least one layer of batt material, or between any two or more layers. At least one of the base fabric, the at least one layer of batt material, or the fabric scrim is comprised of polymeric fibers which are blended with fibers whose modulus of elasticity is substantially less than the modulus of elasticity of the polymeric fibers. Press felts manufactured in accordance with the teachings of the invention provide a retarded elastic spring-back in the vertical (or Z) direction of the felt following the mid-nip point in the press section. This retarded elastic spring-back advances the post nip separation position of the felt and the paper web towards the mid-nip point, thus reducing rewetting of the paper sheet. Fibers comprised of regenerated celluosics, such as viscose rayon, have proven effective for use as the low modulus of elasticity component fibers in the press fabrics of the invention.
摘要:
A netting material (100) includes reflective and/or luminescent markers (110) that make the netting (100) visibile in low light or reduced light situations, and in certain embodiments also marks the roll end in a manner visible in low light situations. The strip (110) reflects a source of light even from a distance and even at a sharp angle, or alternatively emits light itself. The reflective or luminescent strip (110) may be incorporated into the net (100) in addition to and optionally alongside colored roll-end markers that are easily visible in daylight.
摘要:
This disclosure generally pertains to a method for manufacturing a distributed optical fiber scrim comprising a functional optical fiber, the functional optical fiber scrim thus manufactured, and composites in which an optical fiber scrim is incorporated. The present disclosure describes a variety of textile scrims, particularly adhesively bonded nonwoven scrim materials, each comprising at least one optical fiber with a continuous path across at least the length or width of the fabric. Such optical fiber scrims may be useful as sensor components (for example, as a detector of breakage, strain, pressure, or torque), as illumination components (for example, in a variety of light-providing applications), or as data-distribution components, either alone or in combination with other materials, such as fabrics, films, foams, and the like.
