Jean

A 2/1 warp-faced twill fabric used chiefly for overalls or casual wear. Typical construction:35x24; 32x2 Itex cotton; K= 1 9.8+1 1.0.
Note.. The term 'jeanette' is sometimes used to describe the lighter weights and these may be used for linings.

Jerker bar

A yarn auide mounted on the needle bar assembly, for taking up the slack yarn on the needle upstroke of the tufting cycle.(sub category of basic components tufting machine (carpet))

Jersey

1. A circular-knit or flat-knit fabric made with a plain stitch in which the loops intermesh in only one direction. As a result the appearance of the face and the back of a jersey fabric is wholly different. 2. A tricot fabric made with a simple stitch characterized by excellent drape and wrinkle recovery properties. © 2001 Celanese Acetate LLC

Jersey fabric

A generic name applied to weft-knitted fabric. (See also single jersey, weft-knitted and double jersey, weft-knitted.)

Jet

1. A device used to bulk yarns by introducing curls coils and loops that are formed by the action of a high velocity stream usually of air or steam. (Also see TEXTURING Air Jet Method.) 2. See SPINNERET.

Jet (clothing)

A narrow strip of matching or contrasting material sewn parallel to a pocket opening, forming decorative neatened edge on both sides of the pocket mouth.

Jet craters

d the holes on the face of jets used in the extrusion Annular deposits that sometimes form around of viscose. (See also jet rings.)

Jet Dyeing

High temperature piece dyeing in which the dye liquor is circulated via a Venturi jet thus providing the driving force to move the loop of fabric.

Jet Dyeing Machine

A high-temperature piecedyeing machine that circulates the dye liquor through a Venturi jet thus imparting a driving force to move the fabric. The fabric in rope form is sewn together to form a loop.

Jet loom

machines in which the weft thread is taken through the shed by a jet of air or liquid.

Jet rings

Annular deposits formed occasionally inside the holes of metal jets or spinnerets when used in the extrusion of viscose, particularly into coagulants containing much zinc sulphate. (See also jet craters.)

Jet spinning

A system of staple-fibre spinning which utilises an air vortex to apply the twisting couple to the yarn during its formation.
Note: The air is blown through one or more nozzles inclined to the axis of the cylindrical yarn passage (see diagram 1). This generates a vortex in the passage which applies a torque to the yarn as it passes through. Two such twisting devices may be used (see diagram 2). The majority of systems using this spinning technique produce a type of fasciated yarn. (See also spinning.)

Jet weaving machine

machines in which the weft thread is taken through the shed by a jet of air or liquid.
