CPR Textile & Document Restoration 2

Question 1

When restoring smoke-damaged wool textiles, which cleaning approach is most appropriate for delicate fibers?

Accepted Answer

Dry cleaning solvent with gentle hand manipulation

Answer

Dry cleaning solvents with gentle hand manipulation protect wool fibers from shrinkage and felting that hot water or agitation would cause.

Question 2

Which document stabilization method is preferred for water-damaged, moldy paper records before drying?

Accepted Answer

Freezing to halt mold growth and allow controlled drying later

Answer

Freezing halts active mold growth and buys time for controlled freeze-drying or air-drying without further biological damage.

Question 3

What is the primary risk of using ultrasonic cleaning on antique silk textiles?

Accepted Answer

Fiber breakage due to cavitation energy

Answer

Ultrasonic cavitation generates micro-implosions that can sever already-weakened silk fibers, causing irreversible damage.

Question 4

When packing water-damaged books for transport to a drying facility, which material should be interleaved between pages?

Accepted Answer

Unprinted white paper towels or blotter paper

Answer

Unprinted blotter or white paper towels absorb moisture without transferring ink or chemicals to the damaged pages.

Question 5

In textile restoration, what does 'deodorization via ozone' primarily target on fabric?

Accepted Answer

Organic odor molecules from smoke or mold

Answer

Ozone oxidizes organic odor molecules embedded in fabric fibers, neutralizing smoke, mold, and biological odors.
