Creped Wadding; synonymous with “tissue” Creped Wadding Machine; an old term synonymous with “tissue machine” see “Twin Wire Former” a particle between 10 and 2000 angstroms in size Cost Of Goods Manufactured synonymous with “cross-machine direction” Chemcial Safety Application Clearance Dryer Basis Weight the basis weight of thesheet on the Yankee dryer BEFORE creping; usually expressed in “bone dry “terms Distributed Control System Double Re-Crepe; a tissue manufacturing process that has two recreping steps; there are three creping steps in total Dry Strength Additive; a wet-end chemical to increase the dry tensile strength of tissue Dryer Side Out. Refers to the side of the tissue that was against the Yankee dryer during manufacture; the dryer side of the sheet usually faces outward on a wound roll or on a multiply tissue synonymous with “Delta Velocity” the speed of the jet minus the speed of the former; also called Delta V in drag forming, the delta velocity is negative in rush forming, the delta velocity is positive creping at a consistency of 90% or greater a device used to control cross-machine direction moisture profiles through the use of electro-magnets Experimental Converting Unit located at the X-mill in Neednah edge crush test Experimental Forming Unit; a high speed pilot tissue machine at the Experimental Mill in Neenah, WI Eucalyptus Hardwood Kraft; a short, fiber derived from eucalyptus trees; sometimes called a “softness fiber” because of the softness it imparts to the tissue Eucalyptus:see “EHWK” extended nip press Exponentially Weighted Moving Average: a quality system for controlling and accepting product on-line. Latest evolution of in-process acceptance testing Finished Basis Weight Finite Element Modeling First In First Out; a method of managing inventories where the oldest material in inventory (e.g. first in ) is used first (e.g. first out) Finished Product Specification; the specification that defines the acceptable physical characteristics of the finished Felt Side Out; refers to the side of the tissue that was against the felt during manufacture; the felt side of the sheet faces outward on a wound roll or on a multi-ply tissueBiblioteka DSODelta V

fibre satruation point an essential factor describing the state of fibre, this expresses the amount of water within the fibre cell wall FSP differs to different pulps and is typically 0.7-1.8 A facial tissue product design introduced in the USA in 1994; the design was based upon CTEC technology (100% DSA for tensile development, layered forming, single pressure roll, ~1% creping moisture ) a bundle or network of fibers, typically in a thin stock slurry or in a formed sheet (e.g. floccy formation) Flocculation:the process wherein dispersed fibers begin to agglomerate, forming “flocs” Good Manufacturing Practices; governmentally mandated practices associated with the manufacture of certain products Geometric Mean Tensile; the square root of MD tensile times CD Tensile; also call “Invariant Tensile” Gallons per minute gas turbine human machine interface Heavy Wet Crepe; refers to a wet-pressed tissue manufacturing technology which utilizes high (40-50%) creping moisture and heavy basis weights synonymous with “Basis Weight” old term used to describe tissue coming off of the tissue machine that is dropped onto the floor, onto a conveyor, or into the under-machine pulper; if this happens for long, piles of tissue reminiscent of “hay piles” result Inside Diameter the radio of the jet speed to the wire (or former) speed; in drag forming, the jet/wire radio is less than 1.0; in rush forming, the jet/wire radio is greater than 1.0 Knocked Down Flat; a style of corrugated container that is folded and glued and lies flat until ready to be opened and filled

air dry Air Dry Basis Weight:the basis weight of a tissue whose moisture content is in equilibrium Air Dried Tissue (ADT) air make-up units VOITH patented: Advanced Tissue Molding System VOITH claims that the same quality as TAD in terms of bulk and absorption can be achieved for about 60% of the overall capital cost bone dry Beached Chemi-Thermo Mechanical Pulp; CTMP made using alkaline peroxide; yields more flexible, brighter fibers than CTMP bone-dry unit represents 2400 pounds of chips or residues Biological Oxygen Demand; a measure of the mount of oxygen consumed by bacteria in the biological processes that break down organic matter in water; the higher the BOD the more organic matter (e.g. pollution) in the water Basis Weight weight per unit area; typically “pounds per 2880 square feet ” or “grams per square meter (a.k.a. gsm)”; sometimes called “grammage” synonymous with “Grind Angle” the basis weight of tissue that has been dried to zero moisture content; BDDBW = done dry dryer basis weight; BDFBW –bone dry finished basis weight, etc. Corrected Cross-machine Direction; cross-machine direction tensile corrected for machine direction stretch Cross-machine Direction; parallel to a line which traverses the width of the tissue machine, sometimes denoted “CMD”; also refers to Cross Deckle Cross-Machine Direction Tensile-Wet CD Tension computational fluid dynamics Continuous Handsheet Former; a low speed pilot tissue machine at the Experimental Mill in Neednah, WI 热电联产 synonymous with CD; e.g. Cross-Machine Direction corrosion-tensile steel (atmospheric-corrosion-resistant, high-strength steel) Coefficient of Variation; typically derived by dividing the standard deviation by the average (mean); other variants of COV are also used (e.g. 6 standard deviations divided by the average); usually expressed as a “percentage” Canadian Standard Freeness; a measure of a furnishes ability to drain water under standard consistency and temperature; also called “Freeness” consumer use-testing
