Ikat A traditional technique resulting in a streaky effect, created by tying and dyeing lengths of yarn before weaving.
Ikat Dyeing A process of dyeing originated in Indonesia and Malaysia in which a warp is dyed to a pattern through the use of resist agent. The warp is made first in rope form and predetermined sections are bound tightly to protect that section from the dye. When the warp is opened out after dyeing, a pattern is shown on the warp, which comes through into the woven fabric (warp ikat). A variation can be achieved by dyeing the weft yarn in a similar way (weft ikat) and in some cases both warp and weft may be treated (double ikat). Careful control and planning can give interesting and unusual figured effects in the cloth. The pattern shapes tend to have soft edges due to some relative movement of the threads in weaving, and a certain amount of bleeding and capillary action in the dye process.
Ikat Fabric Fabric made from ikat dyed materials.
IMA Acronym for 'International Mohair Association'. An association of major producers and users of mohair whose basic aim is to promote use of mohair throughout the world and to establish an international mohair mark on all products made of the luxury fibre. Its purpose is similar to the International Wool Secretariat.

Indigo A type of blue dyestuff originally obtained from the indigo plant but now produced synthetically. Used for denim.
Indigo A variable colour averaging a dark greyish blue. A natural dye material of a deep blue colour. Natural Indigo is perhaps the oldest dye known to man. The oldest historic texts speak of it, as in the colours chosen for the Tabernacle of the Arc of the Covenant. The oldest fragments of cloth are dyed with it. It was the original dye of the "Levi's" blue jeans, a trademark colour for durability. Natural Indigo is one of the fastest dyes known to man and is the only natural blue dye of permanence. Indigo is a blue vat dyestuff that was originally taken from the "Indigofera tinctoria" plant by fermenting the leaves of the shrub. In 1897, fourteen years after Adolf von Bayer identified the chemical structure of indigo, the chemical became synthetically manufactured.Indigo's inherent features are good colourfastness to water and light, a continually fading and its inability to penetrate fibres completely. This allows the blue color in jeans made from indigo to always look irregular and individual.There is no dyestuff like it!.Development of synthetic indigo from coal tar products and other hydrocarbon sources has made the use of natural indigo almost obsolete. Vat dyes in big volume go into the dyeing of blue denim for work cloths. See also Vat dyes

Integral Garment All knitted garments are classified into four classes according to general production methods; Fully cut, Stitch shaped cut, Fully fashioned and Integral. Integral garments (also known as 'Integrally knitted garments') is weft knitted garments, so con-structed, that they require little or no cutting, and little or no seaming operations to finish them. Integrally knitted garments are those that are essentially knitted in one piece with little or no seam. The archetypal example is the beret, which is knitted sequentially in a series of triangles, leaving the beginning and the end to be joined into a three dimensional shape. This principle has also been used to make skirts and jumpers and is used to produce a large proportion of ladies and gents millinery. Another integral garment using a combination of tubular knitting and shaping is the men's sock or half hose. To shape the heel and toe of a sock, pouches are formed from extra rows of knitting. The third common type of integral garment consists principally of joined tubes - the glove. Tubes are constructed for each of the digits, sometimes with shaped tips, and merge together into the palm portion, (also a tube). With some latest model machines, it is now possible to knit such gloves, fully automatically with no subsequent making up procedures. The general production sequence of integral garment (e.g. Half hose) is: Knit half hose
Finish press Developmental work is fast progressing on integral garment manufacturing of upper body outerwear apparels too. The main advantages of integral concepts are savings in both raw material and labour costs at the expense of lower machine output. The electronic V-bed knitting machines in their pres-ent state of development, with presser foot or holding sinkers, are easily capable of producing gar-ments in all the garment categories.
Integral Knitted Garments See Integral garments
Integrated Hangtag This is an integration of price ticket information (UPC, Price, etc.) onto a hang tag. This process eliminates the need for having a hang tag plus a price ticket. The integrated hang tag allows you to merge the creative aspect of hang tags with the boring but necessary information from a traditional price ticket. Essentially, this allows for an updated version of an old fashion price ticket.

Integument In sericulture, refers to the covering of the silkworm's body.
Intensity Refers to the brightness or the dullness of a colour, corresponds to saturation or the purity of hue that a surface can reflect. When red is all red it is said to be in full intensity. When black, white, or grey is used in the colour there is a neutralization or a reduction in the intensity.
Interchanging Double Cloth See under Double cloth
Interfacing Woven or non-woven fabrics used to give body to certain areas of a garment. It adds to the outward appearance of the garment if some areas are reinforced, e.g. collars, buttoned openings, cuffs, pocket flaps, and this structuring also makes the garment last longer. Interfacing has always been a vital and integral part of tailoring, but until comparatively recently was regarded as less important in dressmaking. Now, however, a very wide range of types and weights of interfacing is available, so it is not difficult to interface correctly and improve the garment. Choice depends entirely on the fabric being sewn. In general, the interfacing used in dressmaking should be lighter and softer than the fabric, otherwise the interfacing will take over and make the area where it is used to appear different. See Non-woven canvas, Woven canvas, Iron-on canvas
Interlaced Yarn See Intermingled yarn
Interlining An insulation, padding, or stiffening fabric, either sewn to the wrong side of the lining or the inner side of the outer shell fabric. The interlining is used primarily to provide warmth in coats, jackets, and outerwear.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. Interlining may be of woven, knitted, or non-woven material and may be produced with or without a fusible adhesive coating.

Two to four needle thread chain stitching in a parallel formation is joined together on one side of the fabric by interlooping with a single thread. The other side of the stitching may also be joined by one or more threads known as covering threads. The classification of such seams is confused, in that they fall into two groups within the BS/ISO system.
Interlock, Weft-Knitted A double-faced rib-based structure consisting of two 1 x i rib fabrics joined by interlock loops. It is made on machines equipped with two sets of opposed needles, from various materials for a variety of purposes, including outerwear.

Intermingled Yarn A multifilament yarn 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 yarn under light tension through the turbulent zone of an air-jet.Intermingling should be distinguished from air-texturing in which a much higher level of entanglement is achieved with the objective of producing texture or bulk.
Intermingling Jet An air-operated device used as an ancillary to some processes of yarn extrusion, of drawing and of texturing to induce intermingling of filaments and hence yarn coherence. See also Intermingled yarn

International Unit System To simplify international co-operation in all sectors of industry and commerce, the SI unit system (SI = Systeme International d' Unites) was established. The SI is a rationalized selection of units in the metric system which individually are not new and all other units are derived from them. Few changes were necessary for countries that use the metric system, nevertheless some changes were necessary to comply to the international agreed usage of SI. The international system is based on 7 base units. All other units are derived from these units. Conversion factors are 1 or decimal multiples and sub-multiples of 10. A system of prefixes denoting decimal multiples and sub-multiples of the base units has been established. See Tables of international unit system (SI) base units and derived units, & Table of SI units used in the textile industry

Ikat A traditional technique resulting in a streaky effect, created by tying and dyeing lengths of yarn before weaving.
Ikat Dyeing A process of dyeing originated in Indonesia and Malaysia in which a warp is dyed to a pattern through the use of resist agent. The warp is made first in rope form and predetermined sections are bound tightly to protect that section from the dye. When the warp is opened out after dyeing, a pattern is shown on the warp, which comes through into the woven fabric (warp ikat). A variation can be achieved by dyeing the weft yarn in a similar way (weft ikat) and in some cases both warp and weft may be treated (double ikat). Careful control and planning can give interesting and unusual figured effects in the cloth. The pattern shapes tend to have soft edges due to some relative movement of the threads in weaving, and a certain amount of bleeding and capillary action in the dye process.
Ikat Fabric Fabric made from ikat dyed materials.
IMA Acronym for 'International Mohair Association'. An association of major producers and users of mohair whose basic aim is to promote use of mohair throughout the world and to establish an international mohair mark on all products made of the luxury fibre.

Indigo A type of blue dyestuff originally obtained from the indigo plant but now produced synthetically. Used for denim.
Indigo A variable colour averaging a dark greyish blue. A natural dye material of a deep blue colour. Natural Indigo is perhaps the oldest dye known to man. The oldest historic texts speak of it, as in the colours chosen for the Tabernacle of the Arc of the Covenant. The oldest fragments of cloth are dyed with it. It was the original dye of the "Levi's" blue jeans, a trademark colour for durability. Natural Indigo is one of the fastest dyes known to man and is the only natural blue dye of permanence. Indigo is a blue vat dyestuff that was originally taken from the "Indigofera tinctoria" plant by fermenting the leaves of the shrub. In 1897, fourteen years after Adolf von Bayer identified the chemical structure of indigo, the chemical became synthetically manufactured.Indigo's inherent features are good colourfastness to water and light, a continually fading and its inability to penetrate fibres completely. This allows the blue color in jeans made from indigo to always look irregular and individual.There is no dyestuff like it!.Development of synthetic indigo from coal tar products and other hydrocarbon sources has made the use of natural indigo almost obsolete. Vat dyes in big volume go into the dyeing of blue denim for work cloths. See also Vat dyes

Integral Garment All knitted garments are classified into four classes according to general production methods; Fully cut, Stitch shaped cut, Fully fashioned and Integral. Integral garments (also known as 'Integrally knitted garments') is weft knitted garments, so con-structed, that they require little or no cutting, and little or no seaming operations to finish them. Integrally knitted garments are those that are essentially knitted in one piece with little or no seam. The archetypal example is the beret, which is knitted sequentially in a series of triangles, leaving the beginning and the end to be joined into a three dimensional shape. This principle has also been used to make skirts and jumpers and is used to produce a large proportion of ladies and gents millinery. Another integral garment using a combination of tubular knitting and shaping is the men's sock or half hose. To shape the heel and toe of a sock, pouches are formed from extra rows of knitting. The third common type of integral garment consists principally of joined tubes - the glove. Tubes are constructed for each of the digits, sometimes with shaped tips, and merge together into the palm portion, (also a tube). With some latest model machines, it is now possible to knit such gloves, fully automatically with no subsequent making up procedures. The general production sequence of integral garment (e.g. Half hose) is: Knit half hose
Finish press Developmental work is fast progressing on integral garment manufacturing of upper body outerwear apparels too. The main advantages of integral concepts are savings in both raw material and labour costs at the expense of lower machine output. The electronic V-bed knitting machines in their pres-ent state of development, with presser foot or holding sinkers, are easily capable of producing gar-ments in all the garment categories.
Integral Knitted Garments See Integral garments
Integrated Hangtag This is an integration of price ticket information (UPC, Price, etc.) onto a hang tag. This process eliminates the need for having a hang tag plus a price ticket.

When black, white, or grey is used in the colour there is a neutralization or a reduction in the intensity.
Interchanging Double Cloth See under Double cloth
Interfacing Woven or non-woven fabrics used to give body to certain areas of a garment. It adds to the outward appearance of the garment if some areas are reinforced, e.g. collars, buttoned openings, cuffs, pocket flaps, and this structuring also makes the garment last longer. Interfacing has always been a vital and integral part of tailoring, but until comparatively recently was regarded as less important in dressmaking. Now, however, a very wide range of types and weights of interfacing is available, so it is not difficult to interface correctly and improve the garment. Choice depends entirely on the fabric being sewn. In general, the interfacing used in dressmaking should be lighter and softer than the fabric, otherwise the interfacing will take over and make the area where it is used to appear different. See Non-woven canvas, Woven canvas, Iron-on canvas
Interlaced Yarn See Intermingled yarn

International Unit System To simplify international co-operation in all sectors of industry and commerce, the SI unit system (SI = Systeme International d' Unites) was established. The SI is a rationalized selection of units in the metric system which individually are not new and all other units are derived from them. Few changes were necessary for countries that use the metric system, nevertheless some changes were necessary to comply to the international agreed usage of SI. The international system is based on 7 base units. All other units are derived from these units. Conversion factors are 1 or decimal multiples and sub-multiples of 10. A system of prefixes denoting decimal multiples and sub-multiples of the base units has been established. See Tables of international unit system (SI) base units and derived units, & Table of SI units used in the textile industry
