If you are considering purchasing fabric made of polyester, you probably have several questions. This article will give you some information on spun polyester, tow polyester, and other forms. These three forms are most commonly used in apparel and home décor. There are other forms of polyester as well, but these are the most common types. Listed below are some of the benefits of each type. Read on to learn more. We will discuss these three forms and how to determine if they will work for your needs.
Spun polyester
While it is not waterproof, spun polyester is water-resistant. Because its fibers are shorter, water cannot stay in the fabric for a long time. This water resistance makes it ideal for use in wet conditions, such as in outdoor cushions and tablecloths. Also, despite its water-resistance, it is much softer than filament polyester, which means it will dry more slowly. Spun polyester is also more absorbent than filament polyester.
Tow form
The present invention provides a novel method for drawing tow of substantially unoriented polyester filaments in a large tow form. The resulting tow is highly uniform, with excellent physical properties. In a conventional crimping process, filaments in a tow form exhibit a substantially sinusoidal birefringence difference across the fabric's diameter. Moreover, the tow product of the invention is produced by drawing filaments from a plurality of filament bundles.
Fiberfill form
Polyester fabric is commonly used for a fiberfill form. This material is commonly known as polyester fiberfill, and is characterized by its spiral-crimp structure. This type of fiberfill is refluffable, and the particles are formed into small balls that have a low cohesion between them. These balls are then refluffed in a special process in which small tufts of polyester fabric are air-tumbled against the wall of a vessel.
Other forms
Besides the obvious benefits of
polyester fabric, other forms of this fiber include woven and knit fabrics. Spun polyester is especially comfortable and easy to work with. Spun polyester yarns can be used on their own, or combined with other fibers to create blended fabrics that have all the benefits of both. Polyester blended with other fibers has the added benefits of low shrinkage and wrinkle resistance, while cotton offers a natural feel and more absorbency. However, unlike cotton, polyester can also pill and melt when exposed to heat.
Price
Among the most common fabrics, polyester is one of the cheapest materials to purchase. While the price of raw polyester fiber is less than a dollar per pound, the final cost of finished polyester fabrics can reach more than $1,300 per metric ton. After processing, this material is turned into final products and sold to consumers. There are several reasons for the price fluctuation. One factor is the price of raw polyester fiber, which rises and falls depending on demand, manufacturing speed, and shipping costs.
