Textile Dictionary

ABNORMAL CRIMP: A relative term for crimp that is either too low or too high in frequency and/or amplitude or that has been put into the fiber with improper angular characteristics.

ABRADED YARN: A filament yarn in which filaments have been cut or broken to create hairiness (fibrillation) to simulate the surface character of spun yarns. Abraded yarns are usually plied or twisted with other yarns before use.

ABRASION MARK: An area where a fabric has been damaged by friction.

ABRASION RESISTANCE: The ability of a fiber or fabric to withstand surface wear and rubbing.

ABSORBANCE: The ability of a substance to transform radiant energy into a different form, usually with a resulting rise in temperature. Mathematically, absorbance is the negative logarithm to the base 10 of transmittance.

ABSORBENCY: The ability of one material to take up another material.

ABSORPTION: The process of gases or liquids being taken up into the pores of a fiber, yarn, or fabric. (Also see ADSORPTION.)

ACCELERANT: A chemical used to speed up chemical or other processes. For example, accelerants are used in dyeing triacetate and polyester fabrics.

ACETATE FIBER: A manufactured fiber in which the fiber-forming substance is cellulose acetate (FTC definition). Acetate is manufactured by treating purified cellulose refined from cotton linters and/or wood pulp with acetic anhydride in the presence of a catalyst. The resultant product, cellulose acetate flake, is precipitated, purified, dried, and dissolved in acetone to prepare the spinning solution. After filtration, the highly viscous solution is extruded through spinnerets into a column of warm air in which the acetone is evaporated, leaving solid continuous filaments of cellulose acetate. The evaporated acetone is recovered using a solvent recovery system to prepare additional spinning solution. The cellulose acetate fibers are intermingled and wound onto a bobbin o shippable metier cheese package, ready for use without further chemical processing. In the manufacture of staple fiber, the filaments from numerous spinnerets are combined into tow form, crimped, cut to the required length, and packaged in bales.

ACETIC ACID: An organic acid (CH3COOH) widely used in textile applications. It is used in textile wet processing, dyeing and printing, and in the manufacture of cellulose acetate and cellulose triacetate.

ACETIC ANHYDRIDE: Anhydrous acetic acid [(CH3CO)2O]. It is used in the acetylation process in the manufacture of cellulose acetate.

ACETONE: Dimethyl ketone (CH3COCH3). One of the most powerful organic solvents. Acetone dissolves secondary cellulose acetate and other derivatives of cellulose. It is miscible with water and has a low boiling point (55-56°C).

ACETONE RECOVERY: A process for reclaiming the acetone solvent from acetate fiber or plastics manufacture. Usually the recovery process consists of adsorption by activated carbon and re-distillation.

compound, as in the conversion of cellulose to cellulose acetate.

ACRYLIC FIBER: A manufactured fiber in which the fiber-forming substance is any long chain synthetic polymer composed of at least 85% by weight of acrylonitrile units [-CH2-CH(CN)-] (FTC definition). Acrylic fibers are produced by two basic methods of spinning (extrusion), dry and wet. In the dry spinning method, material to be spun is dissolved is a solvent. After extrusion through the spinneret, the solvent is evaporated, producing continuous filaments which later may be cut into staple, if desired. In wet spinning, the spinning solution is extruded into a liquid coagulating bath to form filaments, which are drawn, dried, and processed. © 2001, Celanese Acetate LLC

Burn-out: A brocade-like pattern effect created on the fabric through the application of a chemical, instead of color, during the burn-out printing process. (Sulfuric acid, mixed into a colorless print paste, is the most common chemical used.) Many simulated eyelet effects can be created using this method. In these instances, the chemical destroys the fiber and creates a hole in the fabric in a specific design, where the chemical comes in contact with the fabric. The fabric is then over-printed with a simulated embroidery stitch to create the eyelet effect. However, burn-out effects can also be created on velvets made of blended fibers, in which the ground fabric is of one fiber like a polyester, and the pile may be of a cellulosic fiber like rayon or acetate. In this case, when the chemical is printed in a certain pattern, it destroys the pile in those areas where the chemical comes in contact with the fabric, but leave the ground fabric unharmed.

Buttonhole (eyelet): Formed by a contoured patch of zig-zag stitching, followed by a cut---a portion of which is circular. Eyelet buttonholes are usually used on heavy fabrics and/or with large buttons. A gimp or cord is usually contained within the stitches to provide a reinforcement along the edge of the hole.

Buttonhole (straight): Formed by two pairs of straight, parallel rows of zigzag stitching, followed by a single, straight knife cut. Each end of the row of stitching is secured by a bartack.

Buttons:Specified by design, size, color, and type---such as brass, melamine, or pearl, buttons are either shanked (attached by passing threads through the shank's eye) or holed (attached by passing threads through the button's holes).

Flock: A material obtained by reducing textile fibres to fragments by, for example, cutting, tearing, or grinding.

Flock Printing: A process in which a fabric is printed with an adhesive, followed by the application of finely chopped fibres over the whole surface of the fabric by means of dusting-on, an air blast, or electrostatic attraction. The fibres adhere to the printed areas, and are removed from the unprinted areas by mechanical action.

Flocking :A process in which short chopped lengths of fibre (flock) are applied to an adhesive coated backing fabric or other substrate. The application is usually carried out electrostatically.

Foam Printing: A process in which a rubber solution is turned into a foam and squeezed through a screen to make a rubber print. Also known as puff rubber printing.

Folded Yarn: A yarn made by twisting two or more single yarns together in one operation

Free Shrinkage: Spontaneous shrinkage in the absence of outside influences such as heat or a liquid.

Free Swell Absorbency: The weight of fluid in grams that can be absorbed by 1 gram of fibre, yarn or fabric.

Fretting: the wearing away of filaments through friction. Fuji silk: a spun-silk fabric woven in a plain weave.

Flounce: Hanging strips of material which are normally sewn to the hem of a skirt.

Fringe: An example of trim or embellishment that is used on draperies, upholstery and other soft home décorating goods.

Frieze: A pile fabric with uncut loops with the patterns created by cutting some of the loops or using different color yarns.

It is typically used for non-technical garments, and it is only available at Malden Mills®; 2) Polartec®, also developed by Malden Mills, was created for today's high-performance technical garments, which provides enhanced durability warmth, wind resistance, breathability and weather protection.

Flocking: A type of raised decoration applied to the surface of a fabric in which an adhesive is printed on the fabric in a specific pattern, and then finely chopped fibers are applied by means of dusting, air-brushing, or electrostatic charges. The fibers adhere only to the areas where the adhesive has been applied, and the excess fibers are removed by mechanical means.
