I was involved with the lining stage of the treatment of this object. The Dacron lining technique is used for lining paper objects and drying them under tension. It is particularly helpful with large objects such as oversized maps where even pressure during drying may be more difficult to achieve with other methods. Objects lined in this manner become particularly flat. This technique is known as Dacron lining due to the trade name "Dacron" polyester fabric that is traditionally used due to its smooth, durable surface that readily releases from the lining when dry--other surfaces can be used.
Dacron Lining Steps
-
Use a sanded, plastic surface for lining
-
Apply a thick layer of wheat starch paste to the surface
-
Apply the wet polyester fabric
-
Apply a (50:50) mix of methylcellulose and wheat starch paste
-
Apply the slightly dampened mulberry paper lining sheet smooth side down
-
Apply wheat starch paste
-
Apply damp/wet object (supported on Mylar) face up
-
Roll off Mylar support
-
Allow the layers to dry 12-24 hours
-
Separate the margins of the mulberry paper lining and polyester fabric
-
Separate the margins of the polyester fabric and table and remove from table
-
Flip layered package over and peel polyester fabric off from lined object
-
Trim excess mulberry paper
