Which fiber, when subjected to a burn test, burns quickly with a bright flame, smells like burning paper, and leaves a soft gray ash?
Fiber Identification
Question · Easy
A burn test produces a fiber that curls away from the flame, smells like burning hair, and leaves a crushable black ash. The fiber is most likely:

A synthetic upholstery fiber melts and shrinks away from flame, produces a sweet chemical/celery-like odor, and leaves a hard tan-to-gray bead. The fiber is most likely:
Question · Medium
Which synthetic fiber has a very low melting point, gives off a wax-like or paraffin odor when burned, and floats in water due to its specific gravity below 1.0?
A small fabric sample is dissolved in acetone within a few minutes during a solubility test. The fiber is most likely:
Which fiber dissolves in cold dilute sodium hypochlorite (chlorine bleach), making bleach exposure a critical hazard during cleaning?
Linen is a natural fiber derived from which plant?
Rayon (viscose) is best described as:
Acetate fiber is most notable on the UFT exam because:
Wool is classified as which type of fiber for chemistry and cleaning purposes?
Which fiber is naturally oleophilic (attracts oily soils strongly) and therefore requires solvent or surfactant pre-treatment for effective soil release during cleaning?
Acrylic fiber, in a burn test, produces:
Which two fibers, despite different sources, share virtually identical burn-test characteristics because both are made of cellulose?
Which fiber loses the highest percentage of its strength when wet, making over-wetting and aggressive scrubbing particularly damaging?
A burn-test sample melts AND burns simultaneously and gives off a vinegar (acetic acid) odor. The fiber is:
Which synthetic fiber is most commonly used in upholstery because of its outstanding abrasion resistance, dye-acceptance, and resilience?
A microscopic exam of a fiber shows a triangular cross-section with no internal lumen, and the fiber is very lustrous. The fiber is most likely:
Question · Hard
A woven upholstery fabric is constructed by:
Construction
Knit upholstery fabrics differ from woven fabrics in that they:
In tufted upholstery construction, yarn is:
Which backing material, traditionally used on tufted upholstery and some woven fabrics, is the leading culprit when cellulosic browning appears after over-wetting?
Polyurethane foam used in upholstery cushions can be damaged by:
Down-filled cushions require special handling during upholstery cleaning because:
Polyester fiberfill, when used as cushion filling, generally:
Hardwood vs. softwood frames in upholstered furniture matter to the cleaner mainly because:
A 'velvet' or 'cut-pile' upholstery fabric construction is characterized by:
Chenille upholstery fabric is recognized by:
Jacquard upholstery fabric is best described as:
Cushion springs and 'eight-way hand-tied' construction indicate that:
Latex backing on upholstered furniture can become problematic during cleaning because:
Why must the cleaner perform a dye fugitivity test BEFORE applying any wet cleaning agent to upholstery?
Dye Testing
The standard cotton-swab dye fugitivity test procedure is:
If a swab test with your alkaline prespray shows color transfer but a swab test with your solvent shows none, the correct response is:
An 'alkaline fugitivity' test specifically evaluates whether:
A 'solvent fugitivity' test is used primarily when:
A 'latent stain' on upholstery is best described as:
Why is a dye test performed in an inconspicuous area such as the back of a cushion or under the skirt?
If a fabric has multiple dye colors and the dye fugitivity test shows ANY of the colors transferring to the swab, the correct interpretation is:
A dye fugitivity test is best conducted with which type of cotton swab?
Yellow-to-brown discoloration that emerges during or after wet cleaning of cellulosic fabrics (especially with jute backings) is caused by:
A cleaner identifies a 'Code W' tag under the cushion of a sofa. The cleaner may safely use:
Cleaning Methods
A 'Code S' tag means:
Cleaning Codes
A 'Code WS' (or W/S) tag on an upholstered chair indicates that:
A 'Code X' tag means:
Hot water extraction (HWE) on upholstery differs from carpet HWE primarily because:
'Low-moisture' upholstery cleaning methods are valuable because they:
