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
There are a number of fibers that are in a category on their own - for example, alginates and carbon fibers are just two of that type. This post will concentrate on these fibers.

Alginates
General Properties
Strictly speaking alginates are not synthetic fibers. They are the calcium salt of alginic acid, which is chemically similar to cellulose: one hydroxyl (-OH) group is replaced by a carboxylic acid (-COOH) group on each ring. Alginic acid is obtained from brown (but not red or green) seaweeds. The Latin for sea weed is alga - hence the name.

Brown seaweed used in the production of alginates.

The powdered brown seaweed is treated with causation soda (sodium hydroxide or NaOH) to extract the soluble alginate. The solution is carefully purified and spun on viscose machines into an acid calcium chloride (CaCl2).

Production of alginate fibers.

Alginate fibers have two remarkable properties: they are flame proof because of calcium (Ca); and they dissolve in soapy water, because they are ionic salts. Note: table salt is an ionic salt and it too readily dissolves in water. It is this latter property which gives alginates their commercial importance.

Uses
Delicate laces can be embroidered on alginate supporting cloths. When the fabric is washed, the backing disappears, leaving the fine lace. During the manufacture of socks, hosiery and other repeat-unit knitted items, alginate yarns can be used as separating threads between knitted units. During wet finishings, the socks or hose separate automatically.

An important use of alginates is as thickening agents for printing pastes used in the dyeing trade.

Technique: Dyed, multiple over-dyes including clamp resist, discharged, illumination discharge, stenciled and silk screened employing thickened fiber reactive dyes on cotton voile with silver lurex thread. Size: 1.15 meters (width) x 2.00 meters (length).


Carbon Fibers
General Properties
Carbon in the form of graphite is such an excellent conductor of electricity that it is used as the contact in electric generators and motors.

When used as a textile fiber, carbon prevents the build-up of static electricity in specialised, mainly industrial fabrics.

Carbon can also be included in powder form in the melt of nylons that are to be used in anti-static applications. The small quantity needed minimises discolouration.

Because of their excellent strength and rigidity, carbon fibers have their main outlet as a reinforcement of other fibers as well as plastics and metal alloys.

Carbon fibers are produced by carbonising (heating to very high temperatures, but in the absence of oxygen to prevent burning) organic fibers such as acrylics or high-strength regenerated cellulose fibers. Precise control of carbonising temperatures (up to 3000oC) determines the physical properties of the resultant carbon fiber.
