Current Technology
Originally shade fabric, like all fabrics in the outdoors, suffered from UV degradation. UV inhibitors are now added during the manufacture of shade cloth and good shade cloth now generally comes with a multi-year UV degradation warranties. Shade cloth is a knitted fabric and this is an important factor in using it to design and manufacture shade sails.
Successful shade sail design uses the inherent "stretch" of the knitted fabric to create three dimensional shapes. Fabrics other than shade cloth are used to make shade sails such as PVC, a more expensive alternative, or canvas variations. The low cost of shade cloth and its ability to breathe makes it a prime choice for "cool shade".

Famous quotes containing the words current and/or technology:
“It is not however, adulthood itself, but parenthood that forms the glass shroud of memory. For there is an interesting quirk in the memory of women. At 30, women see their adolescence quite clearly. At 30 a woman’s adolescence remains a facet fitting into her current self.... At 40, however, memories of adolescence are blurred. Women of this age look much more to their earlier childhood for memories of themselves and of their mothers. This links up to her typical parenting phase.”
—Terri Apter (20th century)
“If the technology cannot shoulder the entire burden of strategic change, it nevertheless can set into motion a series of dynamics that present an important challenge to imperative control and the industrial division of labor. The more blurred the distinction between what workers know and what managers know, the more fragile and pointless any traditional relationships of domination and subordination between them will become.”
—Shoshana Zuboff (b. 1951)
