Common Cleaning Terms

Abrasion resistance Durability of a fabric in the face of surface wear
Absorbent Compound Cleaning A cleaning method where compound is spread by hand or specially designed machine. Brushing is used to spread and agitate the compound that absorbs the suspended soil. Following drying the suspended soil and compound is removed by dry vacuuming
Absorbent Pad (Bonnet /Oscillating Pad) A cleaning method where a machine that cleans carpet with an oscillating pad is used. This provides thorough agitation however does not clean deep into the piles
Acid A substance which has a sour taste, reacts with metals and carbonates and has a pH level less than 7.0
Acid Dye Blocker An anionic compound used to block open dye sites in order to eliminate the attraction of acid staining material such as fruit drinks
Acid Dyes A class of dyes used primarily for protein and nylon fibres
Acrylic A generic term for a man-made fibre composed of acrylonitrile units (at least 85% by weight) which are derived from petrochemical by-products
ADS Alkaline Detergent Spotter. pH levels in the alkaline range
Alkaline A solution of a soluble base that has a pH greater than 7.0
Ammonia Ammonia is a gas that, when dissolved in water, yields ammonium hydroxide. It has an unpleasant odour and is alkaline in nature. It helps saponify oils — converting them to soap — helping them solubilise in water. It will attack copper and copper-based metals, giving a bluish discoloration. It can turn red dyes blue and make some dyes bleed
Animal fibres A general term that refers to all natural-protein fibres, including wool, silk and goat hair
Anionic Negatively charged
Anti-corrosive A chemical compound that, when added to a liquid or gas, decreases the corrosion rate of a metal or an alloy
Antistats Used to reduce or dissipate static electricity
AS Acid/tannin spotter. pH levels in the acid range
BCF - Bulked Continuous Filament Filaments that are drawn, crimped, stretched and bulked which is then wound onto cones and shipped to a yarn facility
Beck/Batch Dyeing A process in which separate pieces of fabric are handled sequentially through dyeing and subsequent processes
Berber Carpet style where there are fat looks with coloured flecks. Originally wool but now mostly olefin
Biodegradable is the chemical breakdown of materials by a physiological environment
Bleaching The basic finishing process by which gray goods are scoured and whitened. Bleaching a fabric that has already been dyed is called stripping.
Bleeding A fault in which a dye stuff runs from one pattern area into another.
Blend Combining two or more different fibres before they are spun into a yarn.
Builders Materials that enhance or maintain the cleaning efficiency of the surfactant by tying up the hard water minerals. It also supplies additional alkalinity for neutralisation of acid soils, aids in keeping soil from redepositing on the carpet and emulsifies oily and greasy soils
Burn test Identifying the fibre by lighting it with a flame and observing the reaction
Carbon dioxide Carbon dioxide is a gas that converts from a solid to a gas at minus 78 degrees Celsius. It forms a weak acid called carbonic acid with a pH of 3.7 when dissolved in water. This acid, being unstable, cannot be isolated as a pure liquid or solid. Carbonic acid rapidly decomposes back to carbon dioxide and water, which are much more stable.
Carpet rippling Caused by failure to power stretch the carpet. Alert the consumer that the carpet should settle to precleaning levels once the humidity has stabilised
Cationic Positively charged
Cellulose Organic fibrous substance found in all vegetation that is the basic constituent of both natural and man-made cellulose fibres such as cotton, linen, jute and rayon
Chlorine Chlorine bleach, or sodium hypochlorite, has little cleaning value but it is a powerful oxidiser, especially in an acidic to neutral state
Citrus Gels Same as POG except in gel form
Colour Abrasion The potential loss of colour, particularly in pigment prints or from poor dye penetration.
Colour Fastness A general term denoting the relative durability of dye or pigment colouration to exposure to light, pollutants, or crocking and cleaning processes.
Commercial Carpet Bubbles Improper use of solvents, improper adhesive or inadequate amount of adhesive can cause bubbles
Compound A substance that contains two or more elements that have been bonded together by a chemical reaction. Soap is a compound
Continuous Dyeing A process in which the fabric or greige goods pass through dyeing and subsequent operations without interruption
Cotton A natural cellulose seed-hair fibre
Crocking The rubbing off of excess dye stuff from dry or wet fabric

Denier A unit of weight that indicates the size of a filament; the higher the yarn, the heavier the yarn
Discolouration Colour removed (Bleach, medicine)
Dry Foam Dense foam is produced by a dry foam machine through mechanical aeration of a liquid detergent. A preconditioner may or may not be used prior to application of the foam detergent.

Emulsification Process of dispersing one liquid into another liquid with which it is immiscible (do not mix such as oil and water)
Encapsulation The cleaning agent is brushed into the carpet using a cylindrical or rotary brush machine. The encapsulation chemistry surrounds each soil particle and crystallises it so it can’t attract other soil. The encapsulated particles release from the fibre and are removed through dry vacuuming

Slub A heavy area in an unevenly spun yarn
Soil filtration The microscopic particles of soil that continuously float in the air are filtered by the fibres usually along the perimeters of the room and under closed doors
Soil retardants Filled in crevices of the fibres with Colourless particles to prevent soil from attaching. Carpets became stiff
