A Abrasion resistance The ability of a fibre or fabric to withstand surface wear and rubbing Absorption The process by which a gas or liquid is taken up within a material. Actinic degradation Strength loss or weakening of fibres and fabrics due to exposure to sunlight. AdditivesChemicals added or incorporated in materials to give them different functional or aesthetic properties, such as flame retardancy and/or softness. Adhesion The force that holds different materials together at their interface. Adhesive A material, flowable in solution or when heated, that is used to bond materials together. Adhesive migration The movement of adhesive together with its carrier solvent, in a fabric during drying, giving it a nonuniform distribution within the web; usually increasing towards the outer layers. AdsorptionThe process by which a gas or liquid is taken up by the surface of a material. Aesthetics Properties perceived by touch and sight, such as the hand,, color, luster, drape, and texture of fabrics. Afterglow The flameless, ember-like burning of a fabric. After treatmentProcess usually carried out after a web has been formed and bonded. Examples are embossing, creping, softening, printing and dyeing. Agglomeration A cluster of particles or fibres. Ageing Processing in which products are exposed to environmental conditions that simulate real use or accelerated use, for the purpose of determining their effect on the functional and aesthetic properties of the products. Air forming Utilizing air to separate and transport fibers to form a web. Airlaying Forming a web by dispersing fibres in an air stream and condensing them from the air stream onto a moving screen by means of a pressure or vacuum. AirlaidA web of fibres produced by airlaying. Airlaid nonwoven An airlaid web bonded by one or more techniques to provide fabric integrity. Air permeability The porosity or the ease with which air passes through a fabric. AmorphousNot crystalline. A random rather than a regular arrangement of chains of molecules within regions of a polymer or fibre. Anionic compound A chemical carrying a negative electrical charge. Anisotropic Not having the same physical properties in every direction. In the plane of the fabric, it is related to a non-random distribution of fibres or filaments. Antifoaming agent An additive that minimises the formation of bubbles within or on the surface of a liquid by reducing the surface forces that support the bubble's structure (see SURFACE TENSION). Antioxidant An additive that retards the deterioration of a material's functional and aesthetic properties by reaction with the oxygen in the air. Antistat An additive that reduces the accumulation or assists the dissipation of electrical charges that arise during the processing of fibres, fabrics and films and during the use of such materials. AttenuationDrawing or pulling of molten polymer into a much reduced diameter filament or fibre. 文档下载： |
