Tyvek® is a 100% synthetic material made from high-density spun-bound polyethylene fibers. Lightweight, durable and breathable.  Resistant to water, abrasion, bacterial penetration, and ageing. Tyvek® is an amazing material used to improve a variety of applications across multiple industries.  The name is a registered trademark of the DuPont company, known for its production of chemicals and textiles.

So why is it used in Sunny Bank Mills Archive?  There are many different shapes and sizes of objects and books in the collection.  After the volunteers have cleaned and researched the pages of the books in the collection.  We need to protect the objects from damage and pests.  This versatile material can be sewn into many different shapes to help wrap and keep safe the treasures of the Archive.

The Guard books in the collection are the reference system of the mill.  They are an invaluable part of the collection.  They tell the story of all the cloth that was made at Sunny Bank Mills.  Either by year, season, or by the country the cloth was destined for.  They need a lot of tender loving care to help preserve them.

Guard books before preservation.

Guard books after volunteer preservation and individual bags were created to help with future preservation.
