Are you curious about the weird beginnings of polyester production?

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.

Correct my friend, I am 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 I’m all about, so it may be a bit of a surprise to you that I only found two topics of interest today: poly web material and seatbelt webbing.

Just a quick note — 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.

While I’m thinking of it, 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.

Let’s be honest, 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 main 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 two-inch seat belt webbing 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: There Are Critical Process Steps In Molecular Polyester Fabrication.
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.

Drying

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.

Spinning

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.
