    摘要: A fiber spinning device and process for manufacturing a web of fibers comprising a homogeneous mixture of fibers of different characteristics. Monocomponent fibers of different polymers can be extruded side-by-side from the same die system. Sheath/core bicomponent fibers can be alternated with monocomponent fibers formed of the same core polymer as used in the bicomponent fibers. Bicomponent fibers having a common core polymer and different sheath polymers can be extruded from alternate spinneret orifices in the same die plate. Multiple distribution plates are provided with surface grooves or depressions to direct polymer materials from independent sources to only selected spinneret openings in an array of spinneret openings while maintaining the polymers segregated from each other. Unique products formed from the improved mixed fiber technology are useful as high efficiency filters in various environments, coalescent filters, reservoirs for marking and writing instruments, wicks and other elements designed to hold and transfer liquids for medical and other applications, heat and moisture exchangers and other diverse fibrous matrices.

    摘要: A method and apparatus for incorporating an additive material into a fibrous web to be bonded into an elongated porous element by heating the fibers in a confined forming die with a heating medium adapted to bond the fibers to each other at spaced points of contact. An additive material is admixed with the heating medium and then the web of fibers is contacted with the heating medium/additive material mixture whereby the heating medium simultaneously carries the additive material into the fibrous web and heats the fibers to bond them into the porous element. The apparatus includes an adjustable venturi assembly through which the heating medium passes to create a pressure gradient adapted to aspirate a quantity of additive material and entrain a metered quantity of same in the heating medium. The method and apparatus are preferably used to uniformly inject a surfactant into a stream of steam for producing an ink reservoir for a writing or marking instrument from a web of melt blown bicomponent fibers having a sheath of polyethylene terephthalate.
