Recycled Polyester Fibers- Manufacturing in an eco-friendly way!

Recycled Polyester Fibers- Manufacturing in an eco-friendly way!

Polyester fibers are something that rules modern industry. This is because of the fact that they occupy the largest volume of synthetics exceeding the other synthetic fibers that are in the form of materials like nylons, rayons, and acrylic fibers. These are the fibers that are a result of inexpensive, easily produced from petrochemical sources, and also have a desirable range of physical properties. These are the products that are very strong and light in terms of weight.


They are easily dyeable and are based on the properties to have very good wash and wear properties. The material is very famous for its outstanding properties. Its versatility is the main reason that people prefer the use of these polyester fibers as they are being used in countless applications, blends, and the type of textiles that are used in applications like the apparel industry and household and furnishing fabrics as well. These are also used in order to form microfibers-based products that are usually used for outdoor wear or sportswear as well.


Polyester is seen to be used in the case of carpets, industrial fibers, and yarns for tire cords, seat belts of the car, filter cloths, tentage fabrics, sail clothing, and various other such product that are commonly seen to be used. In the case of the organic synthetic fiber, we see that it is the result of polycondensation of diacid and alcohol. The process that is used in order to perform this task is the process of melting and spinning along with 400% heat stretching.

While manufacturing these fibers as we see that they are a result of 75% of polyester that is produced but the process of continuous polymerization with the use of processes like PTA and MEG. Further, the addition of titanium oxide makes these polyester fibers and filaments dull. The addition of the spin finishes at melt spinning and draw machines provides static protection, cohesion, and various other fictional properties that make these fibers an option that is unable to get processed through the textile spinning machinery without any type of problems. 

Characteristics of Polyester Fibers

These are known for various different advantages, some of which are as follows:

Good strength.


Low absorbency.


Resistance against stretching and shrinking, as well .


Showing resistance to most the chemicals.


Easy to wash and quick to dry as well.


They are crisp and resilient when they are wet or dry.


Wrinkle and abrasion resistant.


It is able to retain heat-set pleats and creases as well. 


Uses of Polymer Fibers 

Polymer fibers are widely seen to be used in various different industries in various applications. These are in the form of industries:


Clothing Industry

It is widely seen to be used in the clothing industry in order to manufacture blouses, shirts, children’s clothing wear, dresses, neckties, linings, and lingerie products. Not only that, but it is also seen to be used in the manufacturing process of underwear, permanent press garments, slacks, suits, etc.


Home Furnishing

These are also used in order to manufacture the home furnishings products like carpets, curtains, bedsheets, and pillow covers as well.


Technical Textiles

These are the product that is also seen to be used in manufacturing floor, coverings, tiles, v-belts, ropes, nuts, ties, and various other products. 


Production Process of Polyester Fiber

Polyester Fiber

It is a manufactured fiber in which the substance that is being used in manufacturing g is in the form of synthetic polymer that is usually composed of at least 85% weight of an ester of a substituted carboxylic acid. This may or may not include substituted therapeutic units and para-substituted hydroxy benzoate units. 

Recycled polyester is also known as rPet, which is made from recycled bottles of plastic. It is considered a perfect way to clear up all the landfills as it is a result of recycled plastic bottles. Recycled polyester is obtained by melting down the existing plastics and re-spinning them into a new type of polyester fibers, while a lot of attention is given to rPET, which is made from the plastic bottles and containers that are thrown away by the consumers. In actuality, polyethylene terephthalate can be recycled from both postindustrial and post-consumer input materials as well. But simply considering an example, five soda bottles yield enough fiber that is enough to produce one extra large-sized T-shirt. 

Recycling plastics might sound like a great idea because not only is it a good way of clearing up landfills, but there are various other benefits that are associated with the use of this recycled PSF. These are in the form of the facts:


Rpet is as good as virgin polyester, but it takes fewer resources


Recycled polyester is something that is very similar to virgin polyester in terms of quality, but with reference to the amount of energy that is required in order to produce them is quite less compared to virgin polyester but gives some quality as the virgin polyester does.

It can also contribute to reducing the extraction of crude oil and natural gas from the earth to make plastic, as using recycled plastic can help us lessen the dependency on petroleum as a source of raw material.


It Helps us clear up the landfills

Recycled polyester is also helpful because of the fact that it gives a second life to materials that are not biodegradable, and thus it can lead to end up filling oceans and lands. Not only it becomes a cause of pollution, but it also becomes a threat to marine life as every year, tons and millions of plastic are deposited in the rivers and the oceans.

Keeping in mind all the benefits that are associated with the use of this recycled polyester, we see that it is something that is widely seen to be used.
