A class of water-insoluble dyes that are applied in a soluble, reduced form from a sodium sulfide solution and are then reoxidized to the insoluble form on the fiber. Sulfur dyes are mainly used on cotton for economical dark shades of moderate to good fastness to washing and light. They generally give very poor fastness to chlorine.
Industry:Textiles
A class of water-insoluble dyes which are applied to the fiber in a reduced, soluble form (leuco compound) and then reoxidized to the original insoluble form. Vat dyes are among the most resistant dyes to both washing and sunlight. They are widely used on cotton, linen rayon, and other cellulosic fibers.
Industry:Textiles
A class of dyestuffs that are applied directly to the substrate in a neutral or alkaline bath. They produce full shades on cotton and linen without mordanting and can also be applied to rayon, silk, and wool. Direct dyes give bright shades but exhibit poor washfastness. Various aftertreatments are used to improve the washfastness of direct dyes, and such dyes are referred to as “aftertreated direct colors.”
Industry:Textiles
A class of positive-ion-carrying dyes known for their brilliant hues. Basic dyes are composed of large-molecule, water-soluble salts that have a direct affinity for wool and silk and can be applied to cotton with a mordant. The fastness of basic dyes on these fibers is very poor. Basic dyes are also used on basic-dyeable acrylics, modacrylics, nylons, and polyesters, on which they exhibit reasonably good fastness.
Industry:Textiles
A change in the shape of a specimen, e.g., an increase in length produced as the result of the application of a tensile load or force. Deformation may be immediate or delayed, and the latter may be recoverable or nonrecoverable.
Industry:Textiles
1. Immersion of a textile material in some processing liquid. The term is usually used inconnection with a padding or slashing process.
2. The rubber compound with which tire cordsand other in-rubber textiles are treated to give improved adhesion to rubber.
Industry:Textiles
1. A system consisting of finely divided particles and the medium in which they are distributed.
2. Separation of light into colors by diffraction or refraction.
3. A qualitative estimation of the separation and uniform distribution of fibers in the liquid during the production of a wet-formed nonwoven fabric.
Industry:Textiles
1. A more or less gradual movement of molecules or ions through a solution or fiber as a result of the existence of a concentration gradient or repulsive or attractive forces.
2. The random movement of gas molecules.
Industry:Textiles
1. A process for combining several strands of sliver, roving, or yarn in yarn manufacturing.
2. The process of twisting together two or more singles or plied yarns, i.e., plying.
3. A British term for twisting. 4. The term doubling is sometimes used in a sense opposite to singling. This is unintentional plying.
5. A yarn, considerably heavier that normal, produced by a broken end becoming attached to and twisting into another end.
Industry:Textiles
1. A measure of the ease of transporting electric charge from one point to another in an electric field.
2. The reciprocal of resistivity.
