Polyester - a synthetic material obtained from petroleum.
Its full chemical name - polyethylene terephthalate.
Mylar has high fiber strength, it is used in the textile industry, in medicine and in many other industries.
Origin of Dacron
The word "polyester" is primordially Russian word,despite his apparent affiliation to any foreign language. There was the word in the 1950s. While polyester fiber was developed in the Laboratory of Macromolecular Compounds of the Academy of Sciences with a distinct strength. Its name is an acronym.
Soon it began to produce fiber inindustrial scale. The raw material for it is oil. The name given to the place of invention, material, him and secure. However, in other countries polyester called differently. For example, in France it tergalii, UK - Terylene in the US - Dacron. There's this story appeared about a decade earlier than in Russia.
The use of Dacron
Mylar fiber has a fairly wide rangeapplication. However, the best known in the form of polyester fabric and knitted fabric. Products made of Dacron almost crumple, do not fade. They are well retain heat. In addition, very strong. However, polyester does not differ hygroscopic, poorly absorb moisture, so from Dacron clothing is not quite hygienic.
Very often, when you create a Mylar fabricfiber is not used by itself, but it is mixed with cotton or wool yarns, and viscose. The result is things that combine the properties of natural materials, and the properties of Dacron. They are less than crumple, remaining comfortable.
In addition to the textile industry, polyester widelyused in medicine. From it produce surgical sutures and is used to create prosthetic materials. Polyester is not rejected by the body's tissues and is not subject to "resorption", which allows implants to remain unchanged throughout a person's life.
Dacron is indispensable in the manufacture of variousindustrial equipment. Because it makes the ropes and fishing nets, conveyor belts and power transmission belts. Mylar fiber is widely used wherever you need extra durability.
In the chemical industry of Dacron docontainers, bottles, packaging material. In this case, the polyester is convenient because it is resistant to aggressive media. He is not afraid of high temperatures, exposure to oxidants, it is not destroyed by being exposed to light for a long time.
Products are marked with the abbreviation Dacron PET or PET (PET in English-speaking countries), which means the full chemical name of the material - polyethylene.
