A polymer made from four distinct monomers.
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.
Quench:
1. A box filled with water into which fabric is run after singeing to prevent sparks or fires. 2. 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, or plastic 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.
Quilting:
1. 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.) 2. The process of stitch bonding a batting or composite.
