IMBIBITION: A measure of the liquid or water-holding capacity of a textile material.
IMMEDIATE ELASTIC DEFORMATION: Recoverable deformation that is essentially
independent of time, i.e., occurring in (a time approaching) zero time and recoverable in (a time approaching) zero time after removal of the applied load.
IMPACT RESISTANCE: 1. The resistance of a material to fracture by a blow, expressed in terms of the amount of energy absorbed before fracture. 2. In yarn or cord, the ability to withstand instantaneous or rapid rate of loading.
IMPREGNATED FABRIC: A fabric in which the interstices between the yarns are completely filled, as compared to sized or coated material where the interstices are not completely filled. Not included in the definition is a woven fabric constructed from impregnated yarns, rather than one impregnated after weaving.
INDEX OF REFRACTION: Ratio of the velocity of light in one medium to its velocity in a second medium as the light passes from medium to medium. If a medium is crystalline, the velocity may depend on the direction of the light with respect to the crystalline axes and the substance may have several indexes of refraction, i.e., it may be birefringent.
INDIGO: Originally, a natural blue vat dye extracted from plants, especially the Indigofera tinctoria plant. Most indigo dyes today are synthetic. They are frequently used on dungarees anddenims.
INFLATABLE STUCTURES: Structures opened or enlarged by input of air and, once enlarged,able to retain the air to maintain the distended position.
INFLOW QUENCH: Cooling air for extruded polymer filaments that is directed radially inward across the path of the filaments. The threadline is completely enclosed in a quench cabinet in inflow quenching.
INHERENT FLAME RESISTANCE: As applied to textiles, flame resistance that derives from an essential characteristic of the fiber from which the textile is made.
INHIBITOR: A substance that retards or prevents a chemical or physical change. In textiles, a chemical agent that is added to prevent fading, degradation, or other undesirable effects.
INITIAL MODULUS: The slope of the initial straight portion of the stressstrain curve. The modulus is the ratio of the change in stress, expressed in newtons per tex, grams-force per tex, or grams-force per denier, to the change in strain expressed
as a fraction of the original length.
INITIATOR: A chemical added to start a reaction such as polymerization. Unlike catalysts,
initiators may be consumed during the reaction.
INSPECTION: The process of examining textiles for defects at any stage of manufacturing and finishing.
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.
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.
INTERLINING: A padding or stiffening fabric used in garment manufacture to provide shape retention. Interlining is sandwiched between layers of fabric.
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.
INTERMITTENT PATTERN: A pattern occurring in interrupted sequence.
INTERNAL DYE VARIABILITY: The change from point to point in dye uniformity across the diameter and along the length of the individual filaments. Affects appearance of the dyed product and is a function of fiber, dye, dyeing process, and dyebath characteristics.
INTIMATE BLEND: A technique of mixing two or more dissimiliar fibers in a very uniform mixture. Usually the stock is mixed before or at the picker.
INTRINSIC VISCOSITY: Ratio of the specific viscosity (R.V.-1) of a solution of known
concentration to the concentration of solute extrapolated to zero concentration. Also called the limiting viscosity number. It is directly proportional to the polymer-average molecular weight.
IONOMER: A polymer having covalent bonds between the constituents of the long-chain
molecules and ionic bonds between the chains.
ISLANDS-IN-THE-SEA: A type of component fiber described as multipleinterface or filament-in-matrix. The “island” are fibrils of one or more polymers imbedded in the “sea” (or matrix) consisting of another polymer. The matrix is often dissolved away to leave filaments of very low denier per filament. These fibers have been used in ion-exchange products and in imitation fur products as well as to produce textile products with a different hand.
ISOTACTIC POLYMER: A polymer structure in which there is a regular spatial or stereo
relationship from one repeat unit to the next.
ISOTHERM: Constant temperature line used on graphs of climatic conditions or thermodynamic relations, such as pressure-volume relations at constant temperature.
ISOTROPIC: Having the same physical properties in every direction in the plane of a fabric. It is related to the random distribution of fibers in nonwoven manufacture.
