Polyester Fiberfill 

Polyester fiberfill pillows are usually less expensive than down or goose feather pillows. They are also non-allergenic and are resistant to mildew. Pillows stuffed with loose polyfill may be prone to clumping and matting. Some polyester fibers are engineered to have hollow air cores which helps them resist matting. Polyester fiberfill batts, or thin flat sheets of fiberfill, may be rolled in a flattened shape to fill a pillow, which makes it less likely to become lumpy.

Synthetic Fiberfill

Synthetic fiberfill is a man-made material that has been spun, coiled or textured to create a dense mass of soft fibers. Fiberfill can be loose or in the form of a flat batt or thicker matt. In pillows it is most often used loose or in a rolled batt. Olefin, a polypropylene and polyethylene fiber, is used as fiberfill, primarily in linings for outerwear. Acetate, derived from plant-based cellulose and acetic acid, is also made into fiberfill and is used as a pillow stuffing. Most pillows stuffed with fiberfill are filled with polyester, according to Penn State University Extension. Polyester fiberfill is just a type of synthetic fiberfill.

Synthetic fiberfills, including polyester, can be machine washed and dried. Wash two pillows at a time for a balanced load, and use warm water and gentle detergent.

It may be necessary to hand fluff pillows after removing them from the dryer by pulling fiber clumps apart with your hands through the pillow ticking.

Synthetic fiberfills of any type can be blended with down to increase softness and durability. Polyester fiberfill batts can also be wrapped around a foam-core pillow to soften the lines. Synthetic down is a type of filling made with finer polyester gel fibers that mimic down’s ability to form to the contours of the sleeper’s head and neck.

Using Polyester FiberFill (Polyfill) for Acoustics Industry

High-quality sound insulation means above all better working conditions, a more pleasant living environment or more comfortable travelling. The enjoyment of music depends to a large extent on the right textile sound insulators. At the same time, however, the correct use of acoustic materials is also the basis for the targeted influencing of any background noise. The materials used also vary depending on the requirements. Our fibers offer the right basis for every desired solution.

Polyfill, also known as polyester fiberfill, is one of the best types of materials used for enclosures. This material is found and sold almost anywhere and is extremely affordable. The material is easy to apply to the inside of your subwoofer enclosure and allows you to add the perfect amount of fill so your box appears bigger to the subs which will then produce better audio quality.

When Poyfill is added to your enclosure, the airspring within the box begins an isothermal process. When the air passes through the Polyfill it is scattered and dissipated by the fibers, causing the air to be less dense. The speaker then interacts with the enclosure as if it is larger than it really is, changing the sound.

Often times you’ll either build or buy an enclosure for your equipment and it will be just a tad too small. In these cases you can easily add some Polyfill to the box to increase the effectiveness of your subwoofer. As long as you are within the manufacturers suggested box volume specs, a larger enclosure is more efficient than a smaller one no matter what size the driver is. Having a large enclosure gives you more options; if your subwoofer enclosure is too small, there isn’t much you can do except build or buy a new one.

On a more negative note, too much Polyfill can prevent your speakers or sub woofers from producing audio at their full potential. Obviously overstuffing the enclosure will restrict the linear movement of the sub and make the quality of the audio sound extremely muffled. Too much also decreases the effective dampening of the speaker which would allow it to bottom out. Polyfill is also not appropriate for every application – if your enclosure is already bigger than the manufacturer suggests, polyfill isn’t needed and could actually negatively impact the sound.

The effects of Polyfill vary for each enclosure, but all will follow the same general rules. The correct amount can help bring out the full potential of your speakers and sub woofers, but too much will make them sound horrible. So do yourself a favor and research the proper amounts of Polyfill to add to your subwoofer enclosures to ensure you have the best stereo system out of all your friends.
