摘要： New fibrous nonwoven webs are taught that comprise a mass of polyethylene terephthalate fibers that exhibit a double melting peak on a DSC plot: one peak is representative of a first molecular portion within the fiber that is in non-chain-extended crystalline form, and the other peak is representative of a second molecular portion within the fiber that is in chain-extended crystalline form and has a melting point elevated over that of the non-chain-extended crystalline form. Webs comprising fibers having such a morphology have a unique combination of durability and dimensional stability. The fibers are generally autogenously bonded at points of fiber intersection.

摘要： A method and apparatus for tentering nonwoven webs during annealing. The nonwoven web of thermoplastic fibers is restrained on a tentering structure at a plurality of tentering points distributed across an interior portion of the web, rather than just along its edges. The nonwoven web is annealed while restrained on the tentering structure to form a dimensionally stable nonwoven fibrous web, dimensionally stable up to at least the heatsetting temperature. The annealed nonwoven fibrous web is then removed from the tentering structure. In one embodiment, the tentering structure restrains the nonwoven fibrous web in a non-planar configuration during the annealing process. The tentering structure includes a plurality of tentering points projecting distally from a tentering support. The tentering points are positioned to be engaged with an interior portion of the web, thus restraining the web during annealing.

摘要： A method for making a bonded nonwoven fibrous web comprising 1) providing a nonwoven fibrous web that comprises oriented semicrystalline polymeric fibers, and 2) subjecting the web to a controlled heating and quenching operation that includes a) forcefully passing through the web a fluid heated to at least the onset melting temperature of said polymeric material for a time too short to wholly melt the fibers, and b) immediately quenching the web by forcefully passing through the web a fluid at a temperature at least 50° C. less than the Nominal Melting Point of the material of the fibers. The fibers of the treated web generally have i) an amorphous-characterized phase that exhibits repeatable softening (making the fibers softenable) and ii) a crystallite-characterized phase that reinforces the fiber structure during softening of the amorphous-characterized phase, whereby the fibers may be autogenously bonded while retaining orientation and fiber structure. Apparatus for carrying out the method can comprise 1) a conveyor for conveying a web to be treated, 2) a heater mounted adjacent a first side of the conveyor and comprising a) a chamber having a wall that faces the web, b) one or more conduits through which a heated gas can be introduced into the chamber under pressure and c) a slot in said chamber wall through which heated gas flows from the chamber onto a web on the conveyor, 3) a source of quenching gas downweb from the heater on the first side of the conveyor, the quenching gas having a temperature substantially less than that of the heated gas, 4) gas-withdrawal mean disposed on the second side of the conveyor opposite from the heater, the gas-withdrawal means having a portion in alignment with the slot so as to draw heated gas from the slot through the web and also a portion downweb from the slot in alignment with the source of quenching gas so as to draw the quenching gas through the web to quench the web. Flow restrictor means is preferably disposed on the second side of the conveyor in the path of at least one of the heated gas and the quenching gas so as to even the distribution of the gas through the web.

摘要： A solar panel backside film used in solar panel constructions. The film comprises a PET film having a net peak area as measured by differential scanning calorimetry of about −15 J/g to about 5 J/g measured from the endpoint of the glass transition (Tg) up to 230° C., and an additive to opacify the PET film. A polymeric layer is adhered to the PET film to create a solar panel backside film. The solar panel backside film generally has a reflectivity of 50% or greater at a point in the visible range of light. Additionally, the solar panel backside film, when applied to a solar panel and exposed to 2000 hours at 85° C. and 85% relative humidity, does not result in exfoliation or visible cracks in the PET film.

摘要： Nonwoven fibrous webs comprise fibers of uniform diameter that vary in morphology along their length. The variation provides longitudinal segments that exhibit distinctive softening characteristics during a bonding operation. Some segments soften under the conditions of the bonding operation and bond to other fibers of the web, and other segments are passive during the bonding operation. Webs as described can be formed by a method that comprises a) extruding filaments of fiber-forming material; b) directing the filaments through a processing chamber in which the filaments are subjected to longitudinal stress; c) subjecting the filaments to turbulent flow conditions after they exit the processing chamber; and d) collecting the processed filaments; the temperature of the filaments being controlled so that at least some of the filaments solidify while in the turbulent field.
