The Differences Between Acrylic Polyester Fabrics
Acrylic fabrics that are dyed before the yarn is created are called Solution-dyed acrylics. The fabrics begin colorless, then the fibers are woven into yarn, and the yarn is dyed before it is woven into a fabric. A liquid acrylic solution is mixed with the dye, and then it is formed into a fiber so it already has color before it is spun into a yarn. The process makes it color-fast and water-resistant. The Solution-dyed acrylics are breathable like canvas and are used in awnings and patio umbrellas. A softer, more porous version is also used for outdoor pillows, bags, and cushions.
Acrylic is used as a base for outdoor fabrics because of its resistance to wrinkling, fading, and mildew growth. To make acrylic-coated polyester, the fabric threads are woven first and then the material is dipped into an acrylic coating to color it. These fabrics are also available in cotton-polyester blends, which typically have a more appealing appearance. Acrylic-coated polyester and cotton blends are typically used to make car and boat protectors but may also be used for patio umbrellas and awnings.
Vinyl-Coated Synthetic Fiber Mesh
Vinyl-coated synthetic fiber mesh is also referred to as slingable fabric. It is often used for outdoor chairs, whose fabric — not the frame — supports your weight. This fabric is strong and unstretchable . Other fabrics, such as solution-dyed acrylic, printed polyester and printed acrylic outdoor fabrics, are not strong enough for these types of chairs. Most slingable fabrics are made of vinyl-coated polyester or acrylic yarns but the composition of materials varies depending on the manufacturer. They are durable and don’t promote mildew growth.
Olefin is a manmade fiber that is used along with other fibers to create outdoor fabric blends. It is used in outdoor furniture and for a variety of other applications, including house wrap, marine coverings and clothing. Olefin is also referred to as polyethylene or polypropylene. It is manufactured in a similar manner as polyester and nylon. The chemicals used are melted and fed through a device called a spinneret head to form long fibers. Olefin typically has a smooth texture and is usually solution-dyed.
