A fiber protective coating system for storing, handling and protecting high modulus fibers is disclosed. An exemplary system includes a plurality of generally elongated and collimated fibers comprising a fiber bundle with fibers mutually bonded by one or more coatings of a resin and formed into a cylindrical configuration of twisted fibers for feeding directly to a loom in order to form a woven fabric.

High modulus reinforcement and dip-coat production method for same

A composite pre-slit tape useful as a protective carrier system for storing and handling high modulus fibers and processes for protecting such fibers are disclosed. An exemplary composite pre-slit tape includes a plurality of generally elongated and collimated pre-slit laminates oriented in a single plane and releasably bonded to a removable continuous backing layer which is in the form of a long thin tape. Each pre-slit laminate includes an adhesive layer located adjacent the continuous backing layer and a fiber supporting layer located adjacent the adhesive layer. In use as a fiber protective carrier, each pre-slit laminate is bonded to a fiber bundle of a plurality of collimated fibers arranged in a single layer. Each fiber is bonded along its length to the supporting layer of the pre-slit laminate. The combination of secured fibers and pre-slit laminate can be fed directly to a loom for forming woven fabric.

High modulus fiber protective carrier systems and methods for their use

A method for continuously treating arylene sulfide polymer by passing the polymer through an extruder operated at conditions to produce mixing action at a temperature above the melting point of the polymer while contacting an amount of oxygen sufficient to produce a reduction of melt flow within a fixed residence time in the extruder.
