The “Pillow Filling Material” column indicates the type of filling material used in the pillow, either polyester fiberfill or down feathers. Process for making bonded fiberballs, wherein individual fiberballs according to claim 7 are individually heat-bonded in an airstream and cooled.

High quality material: Polyfill stuffing are made of high-quality materials, you can see the white color of our fiber filler. We never bleach the material, to make the filler fiber lighter and cleaner, fluffy and soft, fine and dense fiber and high resilience, and you can use it more at ease. Every production process is very delicate, natural white, light and clean, fluffy and soft, full of shape, giving you a pleasant experience to use. Premium polyester fiber fill, fine and dense fiber, good warmth retention, not easy to agglomerate, high resilience. 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. Process for making a bonded product, wherein an assembly of fiberballs according to claim 1 are heat-bonded in an airstream and cooled. Polyester fibers are sometimes spun together with natural fibers to produce a cloth with blended properties. Cotton-polyester blends can be strong, wrinkle- and tear-resistant, and reduce shrinking. Synthetic fibers using polyester have high water, wind, and environmental resistance compared to plant-derived fibers. They are less fire-resistant and can melt when ignited. [2] Aliphatic–aromatic polyesters, including poly(ethylene terephthalate) (PET) and poly(butylene terephthalate) (PBT), poly(hexamethylene terephthalate)(PHT), poly(propylene terephthalate) (PTT, Sorona), etc are high-melting semicrystalline materials (m. p.160–280°C) that and have benefited from engineering thermoplastics, fibers and films.Fiberballs according to claim 1, wherein the fiberfill is coated with a modified poly(ethylene oxide)/poly(propylene oxide) grafted with functional groups to permit crosslinking.

The use of activating agents for the production of high-melting aromatic polyesters and polyamides under mild conditions has been subject of intensive academic research since the 1980s, but the reactions have not gained commercial acceptance as similar results can be achieved with cheaper reactants.

The generally poor processability of aromatic polymers (for example, a high melting point and a low solubility) also limits the available options for synthesis and may require strong electron-donating co-solvents like HFIP or TFA for analysis (e. g. 1H NMR spectroscopy) which themselves can introduce further practical limitations. Some idea of the nature of the fiberballs of the invention, and especially of the nature of the configurations taken up by the spirally-crimped fiberfill therein, can be gained from FIGS. 1 and 2 of the accompanying drawings. For convenience, at this point, reference is made to my copending application, i.e. U.S. Pat. No. 4,618,531, directed to refluffable fiberballs of spirally-crimped polyester fiberfill, and to a process for making such fiberballs, the disclosure being incorporated herein by reference. The objective of my copending application was to provide a synthetic product as a real alternative to down, in the sense of having refluffable characteristics (available from down) and also with washability (unlike down) and at a lower cost than down. As indicated, this objective was obtained by providing refluffable fiberballs from spirally-crimped polyester fiberfill. An essential element was the use of such spirally-crimped fiberfill. Such refluffable fiberballs can be obtained by air-tumbling small tufts of fiberfill (having spiral crimp) repeatedly against the wall of a vessel as illustrated in FIGS. 5 and 6 of my copending application, corresponding to FIGS. 3 and 4 herein. The objective of the present invention is entirely different from the objective of my copending application, as indicated above. Moreover, the fiberballs of the present invention are distinguished from the refluffable fiberballs specifically disclosed in my copending application, by the content of binder fibers, to achieve the bonding and the new bonded products that are the objective of the present invention. Nevertheless, the techniques used for making fiberballs are similar, and essentially the same apparatus may be used in both instances, and FIGS. 1 and 2 may be helpful in visualizing the fiberballs of the invention, and the spirally-crimped fiberfill therein. Ahmed Shafik was a sexologist who won a Ig Nobel Prize on his research regarding how polyester can affect the fertility of rats, [36] dogs, [37] and men. [38]Comfortable and durable: The stuffing fiber is very fluffy and soft and not easily deformed. Perfect for DIY crafts and home projects. For example, the fluff stuffing fill fiber is perfect for dolls, pillows, cushions, pet nests, etc. This filling cotton has a small capacity and can only be used for filling small dolls, etc. If you need to make pillows and other fillings that require more fillings, I suggest you would need multiple pieces to prevent insufficient filling. This filling stuffing is fine and dense, has high elasticity, full shape, the stuffed cotton is soft and fluffy, has a warm effect, very suitable for stuffing for stuffed animals, stuffed pillows, and stuffing for crafts.

Polyester fiberfill is a synthetic fiber used for stuffing pillows and other soft objects such as stuffed animals. It is also used in audio speakers for its acoustic properties. It is commonly sold under the trademark name Poly-Fil, or un-trademarked as polyfill Is it safe to sleep on polyester? a b c d e Pilati F (1989). "Polyesters". Comprehensive Polymer Science and Supplements. Vol.5. Elsevier. pp.275–315. 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.

( January 2023) Durability--Each sample cushion was covered with a fabric having an air permeability of about 100 1/sq.m./sec and its compression curve was measured and recorded as BF (before flexing). The cushion was then submitted to 10,000 successive flexings under a pressure of 13 kPa (about 133 g/sq.cm.) at a rate of 1400 cycles/hour and the compression curve measured again and recorded as AF (after flexing) so as to show any changes in bulk and resilience resulting from the flex test, as percentages (Δ).
