Sunbrella ™

Sunbrella ™ refers to the trademark name for a type of acrylic fibers that are solution dyed. Many of these fabrics are woven in a plain fashion and are used in outdoor applications such as in boat fabrics, awnings and patio furniture.

Colorfastness of Sunbrella ™

Due to the fact that Sunbrella™ fabrics are exposed to outdoor weather and elements they must be quite strong. Specifically, they must be able to hold up well to mildew and sunlight. One of the reasons that natural fabrics such as wool and cotton are not used is the fact that they are not able to hold up as well in outdoor elements. The best type of fiber for outdoor use is synthetic fiber. Some synthetic fibers lend themselves better to use outside than do others; however.

Perhaps the biggest benefit of synthetic fiber is the fact that it is acceptable for solution dyeing. Solution dyeing is preferred because it provides a colorfastness that is really unparalleled. The pigments will become locked inside the structure of the fiber and thus unable to cause problems such as bleeding.

Understanding Acrylic

Many consumers wonder why Sunbrella™ is manufactured with acrylic when at first glance it would seem as though other synthetic fibers such as olefin and nylon would work just as well. The answer lies in the properties of the fibers.

While it is widely recognized that sunlight is responsible for the fading of fabrics. Over time, sunlight can also weaken and eventually even tear apart the chemical bonds that reside within the fiber. Eventually, the fabric will take on an appearance that is somewhat like an aged newspaper. It will become brittle and dry. Dyes due tend to react in different fashions when exposed to sunlight as do fibers. This is the reason that acrylic is used instead of other fabrics in the production of outdoor products. Other textile fabrics simply cannot match the resistance to sunlight that acrylic possesses.

How is Acrylic Impacted by Mildew

Synthetic fabrics do not usually offer a food source that is vital for mildew to grow. All fabrics; however, can become mildewed if they are soiled. The best way to prevent this from happening is to engage in a regular cleaning regimen.

Cleaning Guidelines

With proper care and maintenance Sunbrella™ can be kept free of mildew. The most important step is to make sure that it is washed off every month using clean water. When this is done on a monthly basis, the dirt will not have a chance to become imbedded into the fabric too deeply. In addition, the need for more in-depth cleanings, which might be harmful, can be kept to a minimum by cleaning once a month on a regular basis. A more thorough cleaning should be provided once every couple of years. In some cases, depending on your environment and the type of wear to which your product is subjected, it may be necessary to provide a deep cleaning more frequently. For this type of cleaning, fabrics may be machine washed if they will fit inside the washer; however, they can also be cleaned right on the awning or furnishings as well.

A mild soap is recommended for the cleaning of this product by the manufacturer. Hot water should not be used. Cold water as well as lukewarm water may be used; however. At any rate, the water should not be above 100 degrees. After the cleaning, air drying is the best method. Since the fabric is already outside in most cases, this usually does not present much of a problem.

In addition, diluted bleach is safe to use on this type of fabric. A stronger bleach solution should not be used as it can result in the fabric becoming weak and discolored over time. The diluted bleach solution is best applied using a brush with soft bristles. The solution should be allowed to soak for about twenty minutes and then the fabric should be rinsed completely before being air-dried. As is the case with any type of fabric, whether used inside or outside, you may wish to test a small area first.

Sunbrella™ fabrics can last a long period of time when they receive proper care and maintenance.
