what is polyester made of

The development of polyester.

Polyester was developed in the years 1939 to 1941 by British chemists at Calico Printers Association Ltd.

The Polyester is made up of long-chain polymers. Today there are two major types of polyester called polyethylene terephthalate (PET) and poly-1, 4-cyclohexylene & dimethylene (PCDT).

what is polyester made of

The PET is the most popular type as it is applicable to a wider variety of uses and is stronger than PCDT.  However pls note that, PCDT is more elastic and resilient and is used in heavier consumer applications.

The Synthetic polyester is made using a chemical reaction involving coal, petroleum, air and water.  Polyester is made up of purified terephthalic acid (PTS) or its dimethyl ester dimethyl terephthalate (DMT) and monotheluene glycol (MEG).

pls note that It holds 10% of the market share for all plastic materials, coming third in terms of popularity after polyethylene (33.5%) and polypropylene (19.5%).

how polyester is made

The most common type of chemical reaction used to make polyester takes almost place at high temperatures in a vacuum.

A petroleum by-product, alcohol, and carboxyl acid are mixed to form a compound known as monomer or “ester.” This reaction is known as polymerization. 

The polymer material created during polymerization is extruded while hot into long fibers that are stretched until they are about five times their original length. The resultant fiber forms an arrangement of molecules that is very strong.

how polyester fibers and threads are made

This process involves two steps polyester fibers or threads are made using a spinning process.  There are generally two types of spinning processes.  One of is the filament type, where long poly fibers are twisted together, and the spun types, in which short pieces of poly fiber are combined to form something called “ poly staple.” These processes allow for poly material blends to be made using cotton or wool spun in with the polyester.

the advantages of synthetic materials

The Synthetic fabrics like polyester are often criticized for having a less natural polyester feel than fabrics such as cotton, silk, or wool. However, polyester does have some clear-cut advantages over natural fibers.  Polyester fabrics is wrinkle resistant, more durable and has high color retention.  There is no doubt Synthetic fibers also can exhibit superior water, wind and environmental resistance.

For this good reason, polyester is often used in tents, outdoor clothing such as windbreakers and parkas, and umbrellas. Polyester fabrics have come to replace some of the old school natural fabrics.  For instance, “China silk “ is the term used by the textile industry for fabrics made of 100% polyester that closely resemble the sheen, drape, and durability of insect-derived silk.

what happens when polyester is exposed to heat

Polyesters fabric can be thermoplastics or thermostats. Most polyesters are thermoplastics, meaning they usually change their shape with the application of heat. Polyester fabrics is combustible at high temperatures but tends to shrink away from flames and is self-extinguishing upon ignition. So just leave your windbreakers off of the ironing board!

polyester resins

The unsaturated polyesters (UPR) are thermoset resins. They are used for non-metallic body fillers, fiberglass laminating resins, and casting materials. Fiberglass-reinforced unsaturated polyesters are used in a wide range of applications including the bodies of yachts and automobiles.

uses for polyester

Fabrics and threads made of polyester are used widely in apparel clothing line, home furnishings, and in commercial applications. Some examples include, sport shirts, 100 % polyester fabric hoodies , legging , blankets and hats, bed sheets, and computer mouse pads. 

The Industrial polyester fibers are made into ropes, safety belts, tire reinforcements, and conveyor belts.  Polyester is also used to make bottles, films, and holograms. It is used as a wood finish on pianos, guitars, and yacht interiors.

What’s the Difference Between Man made Artificial and Fabric


What’s the Difference Between Man made Artificial and Fabric? Man made Artificial Fabric Described and Fabric – It was the principle that manmade while cloth comes from a natural source fabric comes from substances. So cloth would include cloth such as rayon and bamboo that come from man and wood pulp made could include fabrics such as polyester, acetate and nylon that come from oil derived plastics and compounds. The industry uses the term Manufactured Fabrics for any of these fabric types. Its fascinating that some cloths live in the world and the natural. For example, latex could be from natural or chemical source latex comes from chemical components and latex comes from the bark. 

what is polyester used for

How Man and Manufactured made Fabric is Made – These materials are made of filaments formed into fibers and extruded fluid. Since the fiber begins as a liquid, a lot of the fibers is colored before they become filament they’re difficult following the fiber is woven into a cloth to dye. Types of Man and Artificial produced Fabric – ACETATE is not a fiber, but may be extruded into fibers of diameter and woven into fabrics having the look of silk, but do not wear such as silk. Acetate doesn’t absorb humidity readily, but dries quickly and resists shrinking. That is a resilient cloth that resists wrinkling along with being flexible and soft with a good drape. 

is polyester warm

Triacetate is a better acetate fabric which does not melt as simple and is simpler to care for. Remember, acetate in nail polish and nail polish remover will melt acetate as will alcohol so take care with perfumes and nail products such as SuperGlue. ACRYLIC is a fine soft and lavish fabric with the majority and hand of wool. Lightweight and springy, this cloth is non allergenic, dries rapidly, draws humidity away from the body and is washable. Acrylic doesn’t take even a moderate quantity of heat. Modacrylics are utilized in pile materials such as fake fur and are more flame resistant.
