    Abstract: An industrial fabric used in the form of an endless fabric belt to form and convey a nonwoven fiber web during the manufacture of a nonwoven fabric has a web-supporting surface which includes rough-surface yarns which inhibit movement, namely, slippage, of the nonwoven fiber web relative to the web-supporting surface. Preferably, the rough-surface yarns make long floats in one or both directions, that is, lengthwise and/or crosswise, on the web-supporting surface.

    Abstract: Secondary carpet backings woven in a flat weave construction from warp tapes and multifilament picks with 50 to about 100% theoretical coverage in the warp but less than full effective coverage and average pick counts of 10 to 20 per inch impart dimensional stability and high peel strength in carpets incorporating the backings and facilitate robust drying rates in manufacture of carpets.

  • Publication number: 20040137817
    Abstract: Improvements in preventing heat- and moisture-shrink problems in specific polypropylene tape fibers are provided. Such fibers are basically manufactured through the initial production of polypropylene films or tubes which are then slit into very thin, though flat (and having very high cross sectional aspect ratios) tape fibers thereafter. Such fibers (and thus the initial films and/or tubes) require the presence of certain compounds that quickly and effectively provide rigidity to the target polypropylene tape fiber after heat-setting. Generally, these compounds include any structure that nucleates polymer crystals within the target polypropylene after exposure to sufficient heat to melt the initial pelletized polymer and upon allowing such a melt to cool. The compounds must nucleate polymer crystals at a higher temperature than the target polypropylene without the nucleating agent during cooling.

  • Publication number: 20040127127
    Abstract: In one embodiment, a fabric comprises a plurality of functional monofilaments shaped to provide anchoring of a coating applied to the fabric and exhibits improved resistance to peeling away of the coating from the fabric. The second embodiment is a fabric comprised of a plurality of bicomponent monofilaments having a first component with at least one receptacle containing a second component, and the fabric exhibiting improved gripping compared to fabric constructed of conventional monofilaments. Methods for making the monofilaments and fabrics are also described.

  • Publication number: 20040102125
    Abstract: An extensible laminate includes a sheet of an extensible nonwoven material that has a fabric side and a film side, a sheet of an elastomeric film, and an adhesive. The adhesive is applied to at least a portion of the film side of the extensible nonwoven material. The extensible nonwoven material is selectively attached to the elastomeric film by a plurality of intermittent adhesive bonds. The extensible nonwoven material is further selectively attached to the clastomeric film by a plurality of thermal point bonds. The intermittent adhesive bonds cover a greater percentage of an interfacial plane between the extensible nonwoven material and the elastomeric film material than the thermal point bonds. A process for making the extensible laminate is also disclosed.

  • Patent number: 6720063
    Abstract: An elastically stretchable composite sheet includes an elastically stretchable first web and an inelastically stretchable second web of thermoplastic synthetic resin fiber which is intermittently bonded to the first web in a y-direction. Component fiber of the second web has its cress-section cut in a direction orthogonal to the y-direction defined by a width w and a height h dimensioned to be at a ratio h/w less than 0.5. The composite sheet having such a structure improve its flexibility.

  • Patent number: 6663737
    Abstract: A core crush resistant prepreg for use in making a fiber reinforced composite panel structure is provided. The prepreg comprises a woven fabric consisting essentially of carbon fiber tow strands impregnated with a hardenable polymeric resin composition. Typically the fabric has an areal weight of from about 180 to about 205 grams per square meter. The prepreg has an average fiber tow aspect ratio of less than about 15.4, a prepreg thickness of at least about 0.245 mm, and a prepreg openness of at least about 1.2 percent but less than about 6.0 percent. Preferably, the resin composition is predominantly viscous in nature and has a tan &dgr; value of between 0.9 and 2.0 at an elevated temperature between 70° C. and 140° C., and an average epoxy functionality of greater than 2.0. A method for evaluating core crush resistance properties of a prepreg is also provided.

  • Patent number: 6610176
    Abstract: A yarn is produced which consists substantially of twisting filaments which are wrapped sequentially upon each other helically upon the yarn in layers, wherein the helically wound filaments preferably are wound right to left and then left to right alternatively to balance the yarn, wherein optionally a glue is applied to one of the filaments to maximize the performance of the yarn in producing paper.

  • Publication number: 20030096114
    Abstract: Fibers or filaments made by using a spinneret orifice having a regular polygonal cross-section. Melt-spinnable thermoplastic polymer is melted and extruded through a spinneret orifice having a regular polygonal cross-section to form molten filaments. The molten filaments are then solidified, and optionally are subsequently subjected to stretching and false twisting processes.

  • Publication number: 20030036325
    Abstract: A composite prepreg material (10) with improved resistance to core crush and porosity incorporates a plurality of different fiber forms having varying cross-sectional configurations. Preferably, the fibers are interwoven in a warp (14) and fill (18) perpendicular orientation pattern. The varying cross-sectional configurations of the different fiber forms causes the fiber forms to have different levels of spreadability and frictional resistance to movement of the fiber. The present invention overcomes the susceptibility to many defects (specifically core crush and porosity) associated with composite material of a single fiber form having a set cross-sectional configuration, by incorporating multiple fiber forms having varying cross-sectional configurations. This multi-fiber form incorporation allows the strengths of one fiber form's properties to help compensate for the weaknesses of another fiber form's properties, and vice versa.
