The Glossary of Terms, Timelines of Fabrics, Dyes and Other Stuff, A Fashion Data Base, Glossary of Colors, Dyes, Inks, Pigments and Resins, Glossary of Fabrics, Fibers, Finishes, Garments and Yarns and Glossary of Art, Artists, Art Motifs and Art Movements have been updated in order to better inform your art practice.

If you find any post on this blog site useful, you can save it or copy and paste it into your own "Word" document etc. for your future reference. For example, Safari allows you to save a post (e.g. click on "File", click on "Print" and release, click on "PDF" and then click on "Save As" and release - and a PDF should appear where you have stored it). Safari also allows you to mail a post to a friend (click on "File", and then point cursor to "Mail Contents On This Page" and release). Either way, this or other posts on this site may be a useful Art Resource for you.

The Art Resource series will be the first post in each calendar month. Remember - these Art Resource posts span information that will be useful for a home hobbyist to that required by a final year University Fine-Art student and so undoubtedly, some parts of any Art Resource post may appear far too technical for your needs (skip over those mind boggling parts) and in other parts, it may be too simplistic with respect to your level of knowledge (ditto the skip). The trade-off between these two extremes will mean that Art Resource posts will hopefully be useful in parts to most, but unfortunately may not be satisfying to all!


Introduction
Foams are used in fabric laminates, as carpet backings, in mattresses, cushions, pillows and pads of various sorts.

On the other hand, poromeric material is a generic term coined from the two major characteristics of the material – a porous structure and polymeric composition.

Foams
Most foams used in fabric construction are made of rubber or polyurethane. Polyurethane is a type of plastic material prepared by the reaction of di-isocyanate with a compound containing two or more hydroxyl groups in the presence of a suitable catalyst.

By the selection of chemicals, polyurethane foams may be obtained with a wide range of physical properties - very stiff and brittle to soft and rubbery. The size of the cells or holes can also be controlled. Chemicals and foaming agents are mixed together thoroughly. After the foam is formed, it is cut into blocks 200 to 300 yards long and strips of the desired thickness are cut from these blocks.

The usefulness of foam is obvious in terms of its worldwide production.

Chemback is a foam product especially designed as a primary backing for carpet tufting. This product consists of a nylon scrim encapsulated in a polyurethane foam, which is approximately 1/8 of an inch thick. It is said to have better process-ability than jute or duck. Because it does not ravel, the carpet requires no edge finish and the performance is improved.


Poromeric Material
Poromeric material is defined as a micro-porous and permeable cariaceous sheet material comprising a urethane polymer material reinforced with polyester. Corfu is a registered trademark of the Du Pont Company.

Corfam is not considered a plastic, an imitation leather, or a leather replacement, but rather a new basic material. The first end-uses were shoe uppers and gaskets, packings and beltings for industrial equipment. Other uses are handbags, luggage, upholstery, and home furnishings and ready-to-wear clothing. It is interesting to note that the end-uses are the same as for leather.

Corfam is like leather in its fibrous structure. In cross-section, the Corfam changes from a loosely arranged fibrous structure at the base to a rather tightly built structure at the top. Corfam is easy to clean, resistant to scuffing, holds its shape, and can be finished to resemble leather or in ways leather can never be finished.
