What Is Polyamide Fabric?

What Is Polyamide Fabric?
Polyamide fabrics, also called nylon fabrics, were developed by the distinguished American scientist Carothers and a scientific team under his leadership, and were the first synthetic fibers to appear in the world. It was patented in the 1930s by the famous American company DuPont. It is popular with the public because of its remarkable elastic structure.

History of Polyamide Fabric.

In the mid-1930s, DuPont developed polyamide as an alternative to stockings.

During World War II, they used polyamide textiles such as polyamide as a parachute material, and the lack of fabric forced many women to make clothes from recycled parachutes.

As a result, they used polyamide in women's clothing, although it was a pure polymer version that was used in clothing for a short time. Consumers around the world soon realized that pure polyamide was not suitable for textile use.

Polyamide fabrics have low permeability and will melt if exposed to extreme temperatures.

However, when polyamide was blended with other materials, it would give it unique properties such as flexibility and silkiness, which led to the increasing use of polyamide with cotton, polyester and wool.

By 1945, polyamides accounted for 25% of the global textile market share, but interest in polyamides has diminished over time.

To date, polyamide fibers account for only 12 percent of global synthetic fiber production.

Other types of polyamide fabrics are commonly used in a variety of consumer and military applications. These include toothbrushes, combs, firearm parts and various types of food packaging.

How Is Polyamide Fabric Made?

(1) Spinning: After extruding and melting the nylon material, the melt is obtained. Then, the melt is spun into preoriented yarn and spun into deformed yarn by stretching machine.

(2) Weaving: The obtained deformed filaments are subjected to finishing, sizing and weaving operations with water jet looms to obtain blank fabrics.

(3) Dyeing: The blank fabric is first cold rolled and pile pre-treated and desizing, then dyed.

(4) Shaping: The dyed treated cloth is first shaped at high temperature and then subjected to anti-drilling coating finishing and/or micro porous wet coating finishing to obtain semi-finished products.

(5) Washing: The above obtained semi-finished products are washed with water with the addition of washing aids to obtain said nylon fabric.

Said washing auxiliaries include the following components according to weight: 10-30 parts of softener, 10-30 parts of fluffy agent, 20-40 parts of antistatic agent, 5-15 parts of silicone oil.

Polyester fabrics are generally breathable, and the small spaces between polyester fibers do allow some air circulation.
Polyamide fabric is not as breathable. It is better suited for windbreakers, down jackets or hiking wear. Natural fibers can be added and improved, such as nylon cotton.

Color fastness

Color fastness is the ability of a fabric to hold dye in the wash without fading or bleeding. It is important to note that even if each fabric is made from the same materials, they are combined in different ways. This has a lot to do with the color fastness of each fabric.

Polyester belongs to the chemical fiber, color fastness is much higher than a natural fiber, general polyester fabrics require color fastness of 3.5 grade or more. Color fastness four or more polyester fabrics, light colors when washing almost no fading, while dark colors (such as black, red, navy, etc. will have a slight fading).

Nylons usually lose color, that is because nylon in the dyeing of common dyes are neutral, or acidic, are in the surface of the nylon silk coloring. When it comes to special environment or its own color fastness is not good, it will lose color. Such as polyamide in the sunlight easily fade.


Polyester and polyamide are both very durable.
Polyester is resistant to shrinkage and wrinkles. It also does a good job at resisting stains. These qualities make polyester an excellent choice for garments that will take a lot of wear and tear.

Polyamide is a little more durable. This is because it has high abrasion resistance. Polyamide is also oleophobic, which means that it does not absorb oils and fats from sweat and does not retain odors.

Moisture wicking

Polyester fabrics have poor moisture absorption, so polyester clothing can feel stuffy when worn, while easily carrying static electricity and staining dust, which affects aesthetics and comfort. However, it is extremely easy to dry after washing, and the wet strength hardly decreases, does not deform, and has good wearable performance.

Polyamide has high moisture absorption, because of its not completely breathable characteristics, it will keep a little moisture for a period of time and not easy to dry.


Polyester is a lightweight fabric because the fabric is tightly woven together, making it stiff and uncomfortable to the touch.
Softness is one of the advantages of nylon fabrics, and this combination of softness and flexibility makes polyamide a very comfortable fabric.


Polyester is virtually devoid of any stretch or stretch. Although polyester is heavily used in apparel, polyester fabrics are blended with fabrics that have stretch to make them more elastic.

Polyamide fibers are more flexible, and nylon fabrics have excellent elasticity and elastic recovery and are often used in sportswear.


Polyester does not keep you warm very well, because the fabric can breathe. However, polyester can be used as a base layer for clothing and can prevent static electricity in clothing.

Polyamide is not warm, absorbs too much water, and is not insulating. It is often used as the outermost layer of clothing, and it takes longer to dry clothes than polyester.


Synthetic fabrics are usually inexpensive to produce because the fibers do not need to be harvested and processed like cotton and other natural fabrics. They are also cheap to produce. However, polyamide does cost slightly more than polyester because it is softer and more flexible.


Polyester fabrics are used for men's and women's shirts, outerwear, children's clothing, upholstery fabrics and carpets. Because of its good elasticity and fluffiness, polyester can also be used as wadding. In industry, high-strength polyester can be used as tire cord, transportation belt, fire hose, cable, fishing net, etc. It can also be used as electrical insulation material, acid-resistant filter cloth and paper blanket, etc.

Polyamide fiber is usually blended with other fibers, so that the fabric has good abrasion resistance and strength, thus more wear-resistant by wearing. Polyamide fiber can be made into elastic stockings, underwear, sweatshirts, raincoats, down jackets and rushing jackets.

Is Polyamide Fabric Breathable?

In fact, nylon fabric is not breathable, but good resilience, high strength, also wear-resistant, moisture absorption. It is more suitable for windbreaker, down jacket or mountain climbing clothes. You can add natural fibers, which will improve, such as nylon cotton material.

Is Polyamide Fabric Washable?

Nylon fabric has good abrasion resistance and resilience. Can be purely spun and blended for a variety of clothing and knitted products. Small density, light fabric, good elasticity, fatigue damage resistance, chemical stability is also very good, alkali resistance but not acid resistance. Long sunlight will become yellow, strength decline, moisture absorption is also bad, but better than acrylic, polyester.

Nylon fabric can use general detergent, the water temperature should not exceed 45 degrees. Do not rub it hard when washing, so as not to appear small hair ball. Can be lightly wrung, not to be exposed to the sun and drying, ventilation after washing and dry, low temperature steam ironing.

Color solid poor so the fabric is easy to fade, to avoid this phenomenon can be soaked in salt water for 5 minutes before washing. Ironing can not use high temperature, otherwise it will cause shrinkage of the fabric as well as sticky phenomenon.

Polyamide Material Properties.

(1) Polyamide can resist weak acids, weak bases and most non-polar solvents, but polyamide does not resist strong acids, strong bases, polar solvents and solutions containing salt.

(2) Polyamide has good stability for mineral oil, animal oil and vegetable oil. When immersed in gasoline for a long time, the properties will not change and the maximum weight gain will not exceed 2%, but the resistance to chloromethane is slightly poor.

(3) The comprehensive mechanical properties of polyamide are good. The tensile strength is between 600-700 kg/cm2, and the impact resistance is mostly 100 kg/cm2 (no notch), only polyamide-9 is higher, up to 250-300 kg-cm/cm2, and the creep value of polyamide is larger.

(4) The melting point of polyamide is not high, generally between 140-280 degrees Celsius. Polyamide long-term use temperature is generally not more than 80 degrees Celsius, and short-term use temperature of up to 120 degrees Celsius, but will make the product color dark.

(6) Polyamide has good low-temperature performance. At low temperature, the strength is reduced very little.

(7) Polyamide has self-lubricating property and good wear resistance.

(8) Polyamide has sound absorption.

(9) Polyamide has good processing properties and can be cut and drilled.

(10) Polyamide products are odorless, tasteless, non-toxic, and will not mold.

Polyamide Fabric Drawbacks.

1. Polyamide absorbs moisture and is more permeable to moisture, and is prone to size shift after absorbing water.

2. Weak polyamide stiffness and easy to wrinkle.

3. The anti-static property of polyamide is not good. The electric property of polyamide, because polyamide is easy to wet, it is difficult to get absolutely dry products, and its electric property changes with the most changes in water content, so in general it is not used for electrical insulation materials.

4. The heat resistance of polyamide is relatively poor.

5. The water absorption and linear expansion rate of polyamide is very large. Especially nylon-6 and nylon-66 are the most significant, the equilibrium water absorption rate in the atmosphere up to 3.5%, at room temperature immersed in water for 24 hours, its saturation water absorption rate up to 10.7%. The result of water absorption causes volume expansion, when the water absorption rate is 3.5%, the linear expansion rate is 0.65%, and when the water absorption rate is 2.3%, the dimensional stability is very poor. After water absorption, the tensile strength of the product is obviously reduced, the reduction can be 30~50%, but the toughness is better, and the impact strength can be increased 3~4 times. Absolutely dry polyamide is hard and brittle, toughness and elongation are very poor, and can not be used, but it will automatically absorb water in the air, with the addition of water absorption, its comprehensive performance has also improved. The water absorption of polyamide decreases with the increase of the carbon chain in the monomer.
