IICRC Carpet Cleaning Technician - Final Test Review 2025 filament - answersa single strand of a natural or synthetic fiber natural fibers - answersMore expensive, require more drying time Ex: Wool Cotton Silk Synthetic Fibers - answersBy-product and man made Ex:Nylon Polyester Olefin Acrylic Two types of Natural Fibers - answerscellulosic=plant and protein=animals Wool - answersNatural crimp so springs back, stains easily, high alkalinity can damage it, very absorbing, comes from fleece, most common natural fiber What fiber type is Opaque and what does that mean? - answersWool, it hides soil well BUT wool absorbs dye therefore it stains easily Cellulosic Fiber Facts - answersStrong, absorbent, shrinks (often used as backing of carpet so carpets don't shrink the backing shrinks) Browning out - answersWhen a cellulosic fiber gets too wet it releases brown dye and you must use an acid rinse to fix it Sisal - answersType of cellulosic fiber, color can be removed when cleaned so best to use dry powder cleaning technique Dry Powder Cleaning - answersSprinkle a powder use a machine to brush it in after 20mins soil should be absorbed then vacuum all the powder up Encapsulation - answersNeutral Cleaner... machine like cymax machine to brush powder in to absorb soil and then vacuum up Jute - answersPlant fiber so *cellulosic*, susceptible to *mold* damage and if over wet it will *shrink* Abrasion - answersScratches on the side of carpet, typical reason why people replace carpet, happens to planet fiber carpets 5 Gen of Nylon - answers1. *round* fibers which *magnified* dirt so 2. The *shape* was *changed* in order to *reduce apparent soiling* 3. Then *carbon core fiber* was added to reduce static 4. Then *Fluorochemical soil repellent* *ex: Teflon*was added to reduce soiling 5. Then when things like kool aid was invented, *acid dye resistance* was applied b/c fluoro is only for soil and didn't repel dyes Nylon is dissolved by - answersFormic acid 2 kinds of ions - answerscations and anions acid dye resistant carpet is cationic so must use anionic cleaning products on it Polyester - answersSynthetic, PET, either disperse dyed or solution dyed, naturally stain resistant, low absorbable bc moisture goes around the fiber, eco friendly and cheaper, hard to dye, attracts oil, crimp loss so can matte and appear darker typically happens in straight lines or sections Solution dyed - answersColor is added to the polymer solution prior to extrusion (so it's dyed before becoming a fiber) Ohliphilic - answersAttracts oil (polyester and olefin) New Polyester is called - answersTriexta Olefin - answersAlso called polypropylene which is the backing of the carpet, least absorbent fiber 10% of moisture, hard to stain, attracts oil, always solution dyed, does not have dye blocker in it so can use cationic cleaners Loop like carpet - answersBerber carpet What carpet does not have dye blocker in it - answersOlefin What fiber type floats on water - answersOlefin Volatile Solvents - answersEvaporates quickly and reacts with chemicals so doesn't need to be rinsed What fiber type does not bounce back - answersOlefin What fiber has a low melting point - answersOlefin which is below 300 degrees Stain vs Spot - answersStain dyes the carpet while spots is something that sits on top of the carpet Wicking - answersthe ability of a fiber to transfer moisture along its surface so soil at base of fiber can come back to the surface causing a stain to reappear and look brown How to avoid wicking - answersThoroughly vacuum or extract, speed dry with fans Acrylic - answersMan made wool that is solution dyed mainly used as doormat, light weight full and soft Rayon - answersAka fake silk art silk or faux silk and you never clean it because it bleeds just vacuum it 3 ways to identify fibers - answersVisual chemical and burn (simple and relatively accurate) Burn test tips - answersUse a lighter with butane because it's odorless and don't burn side that has carpet glue in it, use carpet Awl to lift carpet for a fiber Wool dissolved in - answersSodium hypochlorite Wool smells like when burnt - answersBurning hair Rayon smells like when burnt - answersBurning paper Cotton smells like when burnt - answersBurning paper Acetate smells like when burnt - answersAcetate acid Acrylic smells like when burnt - answersHarsh, acrid charred meat Nylon smells like when burnt - answersCelery or sealing wax Polypropylene Olefin smells like when burnt - answersAsphalt or burning paraffin Polyester triexta smells like when burnt - answersSweet overripe fruit Two types of fibers - answersContinuous and staple Extrusion - answersPush through a hole so forcing molten polymer through a shower head device called spinerette Spinerette - answersa specialized instrument used in manufactured and synthetic fiber production which extrudes chemical solutions through small shaped holes to create continuous filament fibers Crimping - answersProcess of creating bulk, the bend that's put in fiber that causes resilience Pile - answersMultiple layers of carpet Primary backing - answersThe part of the carpet to which face fibers are attached and which holds these fibers in place, where yarn is woven Continuous fiber - answersLong Staple fiber - answersshort fibers measured in inches usually 3-8
