Did you know our humble polyester molecule dates back nearly 100 years??

Hi! To all our followers! As always, I’m your commercial fabrics guy, eager to drop a few lines about truly interesting textile process and procedure concepts.

Your compatriot Roger Howard here writing clever insights for you — indeed, I am the prolific commercial fabrics guy) — and ready to share amazin textiles data with you!

Correct my friend, this is your commercial fabrics guy, and I have yet another textiles historic insight to send your way. Are you new?? Great!! Hello! Roger Howard here, I’m your intrepid author, eager to get into all we’ve found today.

1.5 inch seat belt webbing is what we’ve worked on all these years, so it may seem odd that I only found two topics of interest today: material polyester and strap polyester.

Before I go too far — let me explain — today’s insights come from experts’ posts that my assistant and I uncovered in today’s careful examination of the “Interwebs”.

Truth be told, the information we found today will be of great interest to those who love posts with lots of details in the world of commercial science.

Listen, would you rather see videos? No problem! I’m building a list of relevant videos that will give a bit more depth and insight to commercial fabric manufacturing processes, and plan to include those in my posts in the coming days.

To be clear, I prefer the written word (because I like to study this type of material line by line, and take notes on how I’ll add new options for our clients’ real-world webbing applications!).

Let me be honest, my friends, we have even more to share on our primary site. When you’re ready for better details, take a peek here: 1.5 inch seat belt webbing.

Without further delay, here is what I am eager to share today. This article provides great background and insight to the science behind 1 inch web material:

Durability and strength of the material make it a sought after option for many businesses across the globe. Simple things, like the way the woven material can be preshrunk during the manufacturing process makes it a valuable asset to business that require a fabric with consistently non-shrinking properties.
Allergy sufferers love polyester fabric for its non-allergic properties. In fact, many people prefer the material for making quilts, pillows, bed sheets (among other uses) for this target audience that is willing to pay more to get the relief they need in hypoallergenic materials.

Recent Research Confirms All Of This: It’s No Secret That… Manufacturing Processes Are Critical for Polyester Polymerization.
Initial Fabrication

A catalyst is mixed with ethylene glycol and dimethyl terephthalate at a temperature of 150-210 degrees centigrade. The resulting substance is then combined with terephthalic acid. It is allowed to boil at a temperature of 280 degrees centigrade where it forms polyester which is in liquid form. The liquid is allowed to pass through a machine that makes the filaments, tow, fiberfill or staple.


The liquid polyester ribbons are allowed to cool until hard enough. They are then cut into tiny pieces to ensure that no air was trapped in the filament during the manufacturing process.


Melting of the chips is done at 260-270 degree centigrade, and the resulting solution passes through a spinneret which is metallic and has tiny holes. The holes are of various sizes and forms’ depending on what the company is looking to achieve. It is during this process that different chemicals are added for instance those that will make the final product non-flammable.

After the spinning process is complete, the fiber is allowed to dry. Specialized machines do the draw of fiber. The fibers are soft, and it is at this stage that texturing, twisting and other processes take place. The fiber is then packaged into a form that it will be easier to weave it into the desired material.

The manufacturing process of tow is quite different from that of filament manufacture.in that the spinneret machine has smaller holes. The tow fiber that is produced is stored in containers which are specifically for cooling. With technology advancements and the fact that polyester blends easily with natural materials like cotton, wool among others makes it the best choice for many fashion designers.

Correct my friends, our team first shared this detailed history on our Blogspot account, so feel free to visit our site and read that real version from which this came.
