What is polyester

What is the difference between polyester and polyamide?

Polyamide and polyester are synthetic fibers which, due to their many positive properties, are ideally suited for the production of sports textiles. They are tear-proof and abrasion-resistant and therefore also very elastic and stretchable. In addition, both materials absorb little moisture, which is why water vapor can be transported away from the body to the outside very well. This also causes the fabrics to dry very quickly. In addition, they are largely crease-free and therefore free of iron.

But what is the difference between the two synthetic fibers and what makes them unique?


THE ALL-ROUNDER: POLYESTER

Today, polyester is the most frequently used synthetic fiber in the textile industry and is therefore also used very often at ERIMA. It is light and soft and therefore particularly comfortable to wear. Its very high shape and color stability also make clothing made of polyester very durable and long-lasting. Polyester is particularly breathable and is therefore ideal for sports textiles. It also absorbs less water than polyamide and is more heat-resistant.

IDEAL FOR JERSEYS AND SHORTS

Since polyester is very light- and heat-resistant, clothing made of synthetic fibers can be printed using the transfer process without any problems. The melting point is between 235 and 260 ° C. Nevertheless, very heavy use, such as sliding on the hall floor, can lead to burn holes in sports trousers, for example. This is why our Kevlar goalkeeper pants with cuffs are made of very robust material and withstand such loads even better. In addition to high-quality indoor sports textiles, clothing can also be made from polyester that are wind- and waterproof and are therefore perfect for a wide variety of outdoor activities suitable.

WELL SEWED WITH POLYESTER YARN

By the way, clothing is often sewn with polyester thread. This is more elastic and therefore significantly more tear-resistant than cotton yarn. Since durability, functionality and elasticity are often important quality factors in clothing in sports, polyester is ideal for sports textiles.


EXTREMELY STRETCHABLE AND FAST DRYING: POLYAMI

The lightweight polyamide has the highest strength of all textile raw materials in both dry and wet conditions and therefore has a very high dimensional stability. Garments made of polyamide are therefore just as durable as garments made of polyester. In comparison to polyester, however, polyamide is even more stretchable and elastic. It also dries very quickly, but is sensitive to heat and should therefore not be ironed or only at a very low temperature.

FOR FUNCTIONAL UNDERWEAR AND OUTDOOR JACKETS

Polyamide is particularly suitable for the production of functional underwear or outdoor clothing. Since polyamide fabric dries very quickly and is particularly elastic, it is also suitable for swimming shorts, for example. In contrast, polyester wicks moisture away from the body. But polyester goods are also used in swim shorts. For example, longer men's shorts that are not tight are often made of polyester. The synthetic fiber can also be found in many other sports textiles.


ERIMA QUILTED JACKET: POLYESTER MEETS POLYAMIDE

OurQuilted jacket connects both materials. The outer coating is made of polyamide. Polyester is used as the inner lining and padding. The outer layer made of a polyamide woven fabric is particularly weather-resistant and abrasion-resistant. Polyamide adapts to its environment and absorbs or releases a lot of moisture. Polyamide fibers thus ensure an even heat exchange. When we sweat, the fiber absorbs moisture or heat and stores it; if we get cold later, the fiber releases the stored heat back to us. The filling material of our quilted jacket is therefore light polyester fleece, which dries quickly and transports water vapor to the outside. It keeps you dry and warm and is still breathable.

A quilted jacket should not be confused with a down jacket. Down (feathers) is warming and of course does not meet the technical requirements of designated sports, functional or winter jackets. Even if the outer fabric and inner lining are made of polyamide, moisture can penetrate the inside. Here the moisture or sweat can be absorbed by the polyamide, but probably not be transported away to the outside. Down lining is also not quick-drying, but stores the moisture by absorbing it.


PLEASANT WEARING FEEL

As with so many things, some people also have an allergic reaction to man-made fibers and, for example, get a rash. Most of the time, natural fibers such as cotton are better tolerated by sensitive skin. In some cases, the detergent used can also cause the allergies. The dyes or plasticizers can also be decisive here. ERIMA also offers a wide range of cotton clothing so that everyone can wear the right material for themselves.
