Parallel folds that result in the sheet opening like a fan. Is to simulate the effect of aging in the laboratory. Accelerated Aging Exposing paper at elevated temperature usually at 110 C in an ) Acetate Pulp A highly purified (high alpha cellulose) pulp madeĮspecially to be dissolved in acetic acid, aceticĪnhydride and sulfuric acid to make acetate rayon andĪcetate fiber. Used in weaving operations supplying end-markets such as lingerie, blouses,ĭresses, men’s ties and other apparel. Acetate staple and filament fibers are more commonly Acetate fibers are moderately strong, generally

The resulting product is dissolved in acetone and extruded into filamentsĪnd the acetone evaporated. Vegetable matter and generally wood pulp or cotton linters, with aceticĪnhydride. Acetate fibersĪre derived by treating pure cellulose, which has been extracted from Acetate Fiber A manufactured fiber in which the fiber-forming substance isĬellulose acetate (US Federal Trade Commission (FTC) definition). Accept Accepted portion of pulp after cleaning and or screening Absorbent Paper Papers having the specific characteristic of absorbing Super-absorbent polymers as well as fluff pulps. Advanced cores can contain very specialized absorbent cellulose fibers, synthetic fibers and Super-absorbent polymers composed of polyacrylates. Absorbent cores usually contain a combination of absorbent cellulose fibers (fluff pulps) and Absorbent Core The principal fluid-holding component of disposable hygiene products. Absorbency The extent to which a paper will take up and hold a liquid. (When calibrating a spectrophotometer, often a white ceramic plaque is measured and used as the absolute white reference).

Solid white with known spectral data that is used as the 'reference white' for all measurements of absolute reflectance. Absolute Viscosity A characteristic of one-component liquids which have a constant ratio of shear stress over shear rate (constant viscosity) Absolute White In theory a material that perfectly reflects all light energy at every visible wavelength in practice a In metric system and pounds per cubic feet in English system. Abrasive Papers Papers covered on one or both sides with abrasive powder,Ībsolute Humidity The actual weight of water vapor contained in a unit weight of air, expressed in grams per cubic meter Abrasion Resistance The extent to which paper can withstand continuous scuffing or rubbing.

Abhesive coatings are applied to surfaces Abhesive A material that resists adhesion.
