Intaglio

1. Printing style in which the design is cut into the surface of the cylinder and is thus below the surface. 2. A lustrous brocade pattern knitted in a tricot fabric.

Intarsia

Weft-knitted plain, rib, or purl fabrics containing designs in two or more colours (or textures) within the same course in which each area of colour is knitted from a separate yarn, which is contained entirely within that area.

Integral knitting (weft knitting)

The combined knitting of more than one component during the knitting sequence of a garment, for example, a body plus trimming and a pocket.

Intensity

1. The amount of energy per unit (space charge time). 2. The brilliance of a color. 3. The brightness of light.

Interfacial Polymerization

Polymerization in which two reactive monomers each dissolved in different solvents that are mutually immiscible react at the interface between the two solutions.

Interfacing

See INTERLINING.

Interlaced yarn

Some manufacturers describe such a product as an 'interlaced yarn'.

Interlining

Any one of a wide variety of fabrics used between the inner and outer layers of a garment to improve shape retention, strength, warmth or bulk. An interlining may be of woven, knitted, or non woven material and may be produced with or without a fusible adhesive coating.

Interlock gaiting (knitting)

The opposed alignment of one set of needles with the other on a knitting machine. purl gating; purl gaiting (weft knitting).The opposed alignment oftricks of two needle beds lying in the same plane, on a machine equipped with double-headed needles

Interlock gating

The opposed alignment of one set of needles with the other on a knitting machine. purl gating; purl gaiting (weft knitting).The opposed alignment oftricks of two needle beds lying in the same plane, on a machine equipped with double-headed needles

Interlock Knit

To produce an interlock knit long and short needles are arranged alternately in both the dial and cylinder; the needles in the dial and cylinder are also positioned in direct alignment. When the long and short needles knit in alternate feeds in both needle housings a fabric with a type of cross 1 x 1 rib effect is produced.

Interlock, weft-knitted

A double-faced rib-based structure consisting of two lxl rib fabrics joined by interlocking sinker loops. It is made on machines equipped with two sets of opposed needles (see gating) and capable of knitting in the following sequence:
Note: Interlock was originally knitted from cotton and used for underwear, but today it is knitted from various materials for a variety of purposes, including outerwear.

Intermingled yarn

A multifilament yam in which cohesion is imparted to the filament bundle by entwining the filaments instead of or in addition to twisting. The effect is usually achieved by passing the yam under light tension through the turbulent zone of an air-jet.
Note 1: Some manufacturers describe such a product as an 'interlaced yarn'.
Note 2: Intermingling should be distinguished from air-texturing (see textured yarn, Note 1 (viii)) in which a much higher level of entanglement is achieved with the objective of producing texture or bulk.

Intermingling

1. Use of air jets to create turbulence to entangle the filaments of continuous filaments yarns without forming loops after extrusion. Provides dimensional stability and cohesion for further processing but is not of itself a texturing process. It is compatible with high-speed spin-drawing and high-speed take-up. When compared with twisting processes it also permits increased take-up package size. 2. Combining two or more yarns via an intermingling jet. Can be used to get special effect yarns i.e. mixing dye variants to get heather effects upon subsequent dyeing.

Intermingling jet

An air-operated device used as an ancillary to some processes of yam extrusion, of drawing and of texturing to induce intermingling of filaments and hence yam coherence. (See also intermingled yarn and commingled yarn.)
