Initial modulus

The ratio of stress to corresponding strain below the proportional (Hookean) limit.

Initial recovery

The decrease in strain in a specimen resulting from the removal of force, before creep recoverytakes place.
Note 1: This is sometimes referred to as instantaneous recovery.
Note, 2.. Recovery is usually determined at constant temperature. Thermal expansion is excluded.
Note 3.. For tests on plastics, the initial recovery is generally included as part of creep recovery.

Initiator

A chemical added to start a reaction such as polymerization. Unlike catalysts initiators may be consumed during the reaction.

Ink-Jet Printing

Non-contact printing that uses electrostatic acceleration and deflection of ink particles released by small nozzles to form the pattern.

Inkle

An old term for narrow fabric.

Inkle loom

A simple form of narrow hand loom. It consists of a frame with pegs which hold a narrow continuous warp (a characteristic feature of an inkle loom), a simple device for making two sheds, and an adjustable peg to control warp tension.

Inkle, beggar's

A narrow fabric constructed as linsey-wolsey in the ]8th and early 19th centuries.

Inorine

Originally a worsted fabric similar. to harateen. Now a repp cloth, woven with a coarse cotton warp and a fine cotton weft, the cloth having a moire finish.

Insertion (lace)

Lace, having two straight edges, used for inserting between the edges of two pieces of material.

Insertion braid

A piping made by abraiding machine which produces a flat and a tubular braid in combination.

Insertions

: Banded laces with two straight sewing edges, used for inserting between two panels of fabric

Inspection

Activity such as measuring, examining, testing, gauging one or more characteristics of a product or service and comparing these with specified requirements to determine conformity.

Instron Tensile Tester

A high precision electronic test instrument designed for testing a variety of material under a broad range of test conditions. It is used to measure and chart the load-elongation properties of fibers yarns fabrics webbings plastics films rubber leather paper etc. May also be used to measure such properties as tear resistance and resistance to compression.

Insulating tape

A narrow fabric used in the manufacture of electrical equipment.

Insulation tape

A woven fabric, impregnated with a non-conducting adhesive, which is then cut into strips.
