Polyester and polyamide are two common materials to choose from when making clothes. Both of these synthetic fibers are now very well-liked in the textile sector. However, it’s crucial to recognize the main distinctions between them in order to choose the appropriate fabric.
Although polyester and polyamide may appear to be similar at first, each has advantages and disadvantages of its own. Depending on the use and environment, they can have very different performance, feel, and durability. Making an informed decision can be aided by being aware of these differences.
This article will compare and contrast the key features of polyester and polyamide, pointing out their advantages and disadvantages and advising you on which would be more appropriate for your purposes.
| Characteristic | Polyamide | Polyester |
| Durability | Very strong and resistant to wear | Durable but slightly less resilient than polyamide |
| Moisture Absorption | Absorbs more moisture, can feel less dry | Absorbs less moisture, stays drier |
| Softness | Softer and smoother to the touch | Slightly rougher texture |
| Cost | Generally more expensive | Usually more affordable |
| Heat Resistance | Less resistant to heat, can melt at high temperatures | Better resistance to heat and UV light |
| Environmental Impact | Less eco-friendly, harder to recycle | More recyclable, lower environmental impact |

Differences and similarities between polyamide and polyester
Polyester and polyamide fabrics have similar properties and nearly the same appearance. The primary distinction among textile materials is the raw materials utilized to produce them.
Variations in textile composition can be observed in the subsequent indicators:
- thickness;
- density;
- purpose of textiles.
Description of polyester
Polyethylene terephthalate is the source of synthetic fiber material called polyester. Either ethylene glycol or dimethyl terephthalic acid is the initial material needed to obtain the component. The fibers are obtained from melted raw materials, though the multi-level technological process may vary.
The synthesis involves additives and catalysts. Among the production techniques are:
- transesterification (when obtaining fibers from dimethyl ether);
- polycondensation (if the raw material is ethylene glycol).
Polyester fibers are utilized in the textile industry to create fabrics that mimic cotton, silk, wool, and a variety of non-woven materials, such as synthetic winterizer, isosoft, interlining, etc.
To create mixed materials, natural fibers are combined with polyester threads. This lowers the material’s cost while enhancing a few qualities.
Polyester fiber-based fabrics are smooth to the touch and have a pleasing surface. Medium-density material that is not prone to creases and has low hygroscopicity prevents air from passing through. In addition to being difficult to dye, the fabric can become electrified and lose its color brilliance in direct sunlight.
Description of polyamide
A polycondensation of amides yields polyamide. Plastics made from the processing of coal, gas, and oil (adipic and sebacic acids) are the raw materials used to make fiber.
Material of choice: nylon, perlon, and nylon. a lightweight, breathable, wrinkle-resistant, slightly rough, and low hygroscopicity material. Not only is it easy to dye, but it also doesn’t fade and can repel dirt (well, not greasy stains).
Advantages and disadvantages – which is better to choose
Determining the superiority of polyester over polyamide is a challenging task. Let’s contrast the qualities and functions of the various materials.
Polyamide and polyester offer several benefits.
- long service life;
- attractive appearance, colors;
- easy to care for;
- the material does not wrinkle;
- dries quickly;
- is not susceptible to biological influences (development of mold fungi, damage by moth larvae).
Moreover, polyester has the benefit of being hygroscopic and dirt-repellent. Polyamide has the advantage of being wind- and relatively fire-resistant for outerwear fabrics (it melts when exposed to flames and does not support combustion).
Among the drawbacks, the following should be mentioned:
- low ability to retain heat (except for non-woven insulation);
- accumulation of static electricity;
- deformation under the influence of high temperatures.
The inability of polyester to pass air hinders skin respiration. Since polyamide does not absorb moisture, it is challenging to remove oily stains from it.
Selecting clothing for the winter months should prioritize items with a polyester textile composition label. Polyamide is suitable for the summertime.
Types of fabrics containing polyester and polyamide
Synthetic fiber fabrics and their blends are commonly utilized in the creation of clothing for different demographics. Wear resistance has increased and costs have decreased with the use of synthetic fibers.
Polyamide
The most widely used categories of 100% polyamide fabrics are:
- Nylon and anid. Lightweight and durable materials. The heat resistance of anid is higher than that of nylon.
- Nylon is a durable and lightweight material, some types of which can have a water-repellent surface (special impregnations are used in production).
- Taslan is a textile with a porous texture of the back side, due to which thermal conductivity is ensured.
- Jordan is a breathable water-repellent fabric used in sewing outerwear and shoes.
- Velsoft is abrasion-resistant, soft, breathable fabric with a fleecy surface.
- Tactel. Mainly used in hosiery production. Two-layer structure provides heat retention.
Polyester
Polyester fibers are used to make five types of fabrics:
- Windproof waterproof jordan fabric. Has an iridescent smooth surface. Polyurethane is used as an additive in production.
- Duspo. Used in the manufacture of outerwear. Dense material with polyurethane impregnation, possessing windproof properties.
- Taffeta is a fabric used in the production of goods for tourism. Resistant to chemical reagents and moisture.
- A group of materials for sewing outerwear, demonstrating protective functions – prince, bonding, file.
- Trilobal is a material with a mother-of-pearl sheen.
Popular synthetic fabrics polyester and polyamide have different performance, feel, and strength characteristics. Nylon, or polyamide, is more resilient and softer than other materials, which makes it perfect for high-wear items like sportswear. Conversely, polyester offers greater care-free living and resistance to fading, shrinking, and wrinkling. The most important factors will determine which material is best: polyester is favored due to its affordability and ease of maintenance, while polyamide is superior for comfort and durability.
Application
Underwear, including thermal underwear, outerwear, and adult and child models are all made from synthetic fabrics.
Sewing underwear is appropriate for more elastic polyamide. Sportswear, leggings for cycling, swimsuits, and shorts are all made from these materials. Workwear is made from polyester-based textiles.
For sewing coats, overalls, and jackets, insulation materials such as synthetic winterizer and isosoft are utilized. Interlining is also used in the manufacturing of adhesive pads that reinforce clothing components.
Are there any differences in care
Synthetic fiber products are simple to maintain. They don’t need specialized goods or higher labor expenses. One primary guideline: in order to prevent deformation (creases and folds), such products must be washed at a temperature not higher than 40 degrees.
Ironing is not necessary for items made of polyester or polyamide. They take on their original form and appearance and dry quickly. These kinds of products don’t require moth protection because they use artificial fibers.
The choice between polyester and polyamide frequently boils down to your individual requirements. If you’re looking for comfort and resilience, polyamide is a great option because of its reputation for softness and durability. It works well for items that need to be flexible, such as sportswear.
In contrast, polyester is notable for its low cost and ability to withstand shrinkage and wrinkles. For regular clothing and things that must resist repeated washings, it is perfect.
In the end, each material has advantages, so you should choose the one that best suits your needs, whether that be comfort, toughness, or ease of maintenance.
