CPR Textile & Document Restoration 3 — Questions and Answers
Question 1: A restorer finds tight-woven synthetic upholstery with Category 3 water damage. What is the first step?
- Apply enzyme treatment immediately
- Extract standing water and assess for contamination (Correct answer)
- Send to an off-site textile cleaning facility
- Apply a biocide spray and allow to dwell 24 hours
Correct answer: Extract standing water and assess for contamination
Extracting standing water reduces secondary damage and allows proper contamination assessment before any treatment decision.
Question 2: What is 'blocking' in the context of paper document restoration?
- Applying a chemical barrier to prevent ink bleeding
- Pages or sections fusing together when wet and then dried under pressure (Correct answer)
- Masking undamaged areas before cleaning
- A colorant used to hide water stains
Correct answer: Pages or sections fusing together when wet and then dried under pressure
Blocking occurs when wet pages dry while in contact, causing fibers to bond and pages to stick together permanently.
Question 3: Which fiber type is MOST resistant to mold growth in wet conditions?
- Cotton
- Linen
- Polyester (Correct answer)
- Wool
Correct answer: Polyester
Polyester is a synthetic fiber with no nutritional value for mold organisms, making it inherently resistant compared to natural protein and cellulose fibers.
Question 4: When decontaminating sewage-affected (Category 3) documents that have historic value, what protocol must be followed?
- Discard all affected documents to prevent health risk
- Consult with a conservator before any treatment and document condition thoroughly (Correct answer)
- Dry immediately with heat to kill pathogens
- Apply household bleach solution to sanitize before assessment
Correct answer: Consult with a conservator before any treatment and document condition thoroughly
Historic documents require professional conservator consultation; improper decontamination methods can cause irreversible loss of irreplaceable materials.
Question 5: What does the term 'foxing' refer to on historical paper documents?
- Brown rust-colored spots caused by fungal or oxidation processes (Correct answer)
- Orange tint from iron gall ink degradation
- Foxed texture from repeated folding
- Yellow haze from acid migration
Correct answer: Brown rust-colored spots caused by fungal or oxidation processes
Foxing describes reddish-brown spots on aged paper, resulting from fungal colonies, metal impurities, or oxidation of organic compounds.
Question 6: When restoring smoke-damaged textiles, which step should occur BEFORE wet cleaning?
- Enzyme pre-treatment to break down soot
- Dry soil removal by vacuuming or shaking to remove loose particulate (Correct answer)
- Applying a fabric protector to lock in odors
- Heat drying to set the soot for easier removal
Correct answer: Dry soil removal by vacuuming or shaking to remove loose particulate
Removing loose dry soot before wet cleaning prevents particulate from embedding deeper into fibers when wet.
Question 7: Which drying method is recommended for water-damaged photographs to prevent emulsion damage?
- Face-down air drying on an absorbent surface
- Face-up air drying on a clean screen or rack (Correct answer)
- Blotting with paper towels applied with pressure
- Oven drying at low heat (under 100°F)
Correct answer: Face-up air drying on a clean screen or rack
Face-up air drying on a non-contact surface allows even drying without abrasion to the fragile emulsion layer.
