    Abstract: Apparatus and process for simultaneous crimping and commingling of continuous filament yarns are provided. The yarn is introduced as feed into a contact chamber in which the yarn is contacted with a heated fluid, such as steam, at an angle of not greater than about 85 DEG with respect to the yarn passage axis, and at a fluid velocity sufficient to vibrate the yarn and cause it to impact upon an impacting surface. The impacted yarn, together with the heated fluid, is then directed into an energy tube wherein the impacted yarn absorbs heat from the heated fluid. The heated yarn then passes into a stuffer tube wherein the flow of yarn is impeded, thereby establishing a yarn plug from which crimped and commingled yarn is subsequently removed.

    Abstract: Continuous filaments are fed by aspiration into a stream of heated fluid. The filaments are then contacted with at least a second stream of heated fluid to increase the temperature of the filaments. The combined streams of fluid containing the filaments are directed into contact with a barrier disposed within a chamber at a force sufficient to initiate crimping of the filaments. A major portion of the fluid is separated from the filaments and expelled from the chamber. The filaments are transported through the chamber by continuous movement of a surface therein at sufficient velocity to cause overfeeding of the filaments, whereby the filaments are forced against a mass thereof and emerge from the chamber in crimped form.

    Abstract: The fibre-reinforced thermoplastic sheets consist of an amide polymer, or copolymer contg. >=30% amide, with ave. mol. wt. of 3,000-25,000, in which 10-75% glass fibre of length 3.75 cm. min., are embedded. The polymer is pref. nylon-6 or nylon-6,6, or copolymers contg. >=50% of these. The compsns. may also contain 1-50% of sheet fibre or non-fibrous fillers. The sheets are suitable, when heated to a temp. between their softening pt. and 280 degrees C, for shaping in moulds at ambient temp., is not >10 degrees C above the Tg of the polymer. Owing to the low viscosity and surface tension, and good wetting props. of the polymer, combined with use of long fibres, prodts. of high impact and bend strength, and increased heat deformation temps. are obtained.
