QUALITY: See SECONDS and YARN QUALITY.
QUARTZ FIBER: Pure silica that has been melted and drawn into glass-like fibers. Used for heat resistance and high dielectric strength.
- A box filled with water into which fabric is run after singeing to prevent sparks or fires.
- See CABINET. (Also see QUENCHING.)
QUENCHING: The cooling of fiber filaments after extrusion by carefully controlled airflow. (See CROSSFLOW QUENCH, INFLOW QUENCH, and OUTFLOW QUENCH.)
QUENCH SPACER: The “quiet” zone below the spinneret in which there is no quench airflow. Quench spacer distance is important in controlling fiber orientation and birefringence.
QUETSCH: The nip rollers of a padding machine.
QUILL: A light, tapered tube of wood, metal, paper, orplastic on which the filling yarn is wound for use in the shuttle during weaving.
QUILLING: The process of winding filling yarns onto filling bobbins, or quills, in preparation for use in the shuttle for weaving.
- A fabric construction consisting of a layer of padding, frequently down or fiberfill, sandwiched between two layers of material and held in place by stitching or sealing in a regular pattern across the body of the composite. (Also see PINSONIC® THERMAL JOINING MACHINE.)
- The process of stitch bonding a batting or composite.
