Is nylon water resistant? (2024)

If you've ever owned a nylon raincoat or bag, you may already know that they are often advertised as having water resistant capabilities. However, to answer the question of whether nylon material is waterproof and to understand why nylon has this water resistant property, please follow the article below by EuroPlas.

1. Is nylon material waterproof?

The answer is yes, nylon material possesses a certain degree of water resistance. Nylon is a synthetic polymer composed of molecules bonded together by hydro bonds. These hydro bonds form a protective layer that prevents water infiltration. However, nylon is not entirely waterproof. Prolonged exposure to water or under high pressure, water can seep through nylon.

2. Why does nylon have water resistant properties?

The water resistance of nylon is attributed to its molecular structure. Nylon is a type of synthetic polymer formed by molecules linked together through hydro bonds. These hydro bonds create a protective layer that inhibits water penetration.

When water comes into contact with nylon, water molecules are drawn into the hydro bonds. This generates a force between the water molecules and the nylon, preventing water from infiltrating the interior.

However, nylon is not entirely waterproof. Prolonged exposure to water or exposure to high pressure can lead to water permeating through the nylon.

3. Methods for enhancing nylon's water resistance

There are two primary methods to enhance the water resistant properties of nylon:

3.1. Adding a waterproof coating

This is the most common method to improve nylon's water-resistance. The waterproof coating is typically made from materials such as silicone, polyurethane, or PVC plastic. This coating forms a protective layer that prevents water from penetrating the interior of the nylon.

The waterproof coating can be applied to nylon using various techniques, including printing, laminating, or spraying. The thickness and composition of the coating determine nylon's water-resistance capabilities.

3.2. Nylon modification

Nylon modification involves the introduction of chemical groups into the molecular structure of nylon. These chemical groups alter the properties of nylon, making it more water resistant.

Some commonly used chemical groups for nylon modification include:

• Perfluoroalkyl groups: These groups make nylon smoother, reducing water adhesion.
• Hydrophobic groups: These groups repel water from the nylon surface.
• Fluoropolymer groups: These groups form a protective layer that prevents water infiltration.

Nylon modification is an effective method for enhancing nylon's water resistance. However, this method is often more costly compared to adding a waterproof coating.

4. What is the difference between water resistance and waterproofing?

Water resistance and waterproofing are two concepts often confused with each other. However, there are some fundamental differences between these two terms.

Water resistance refers to the ability of an object or structure to prevent water from infiltrating it. Objects or structures with water resistance can withstand the impact of water in its liquid form but are unable to endure the pressure of water.

Waterproofing, on the other hand, is the ability of an object or structure to prevent water from infiltrating completely, even when subjected to water pressure. Objects or structures with waterproofing can be used in wet or submerged environments without being affected by water.

5. Waterproof and water-resistance standards

Water-Resistance Standards are typically denoted by the initials IP, where:

The first character indicates the degree of protection against solid objects, ranging from 0 (no protection) to 6 (complete protection).

The second character represents the degree of protection against water ingress, ranging from 0 (no protection) to 8 (able to withstand water pressure at depths greater than 1 meter).

Waterproofing Standards are usually labeled with the letter W, and they include:

• W1: Low-level water resistance, capable of repelling light raindrops.
• W2: Medium-level water resistance, can withstand heavy rain and snow.
• W3: High-level water resistance, suitable for heavy rain and showering.
• W4: Very high-level water resistance, effective against seawater, swimming, and shallow diving.
• W5: Absolute water resistance, capable of withstanding seawater, swimming, and deep diving.

6. Which types of nylon exhibit excellent water resistance?

There are several types of nylon known for their excellent water resistance, including:

• Nylon 66: Nylon 66 is the most common type of nylon and offers excellent water resistant properties.
• Nylon 6: Nylon 6 also provides good water resistance, though it may be somewhat inferior to nylon 66.
• Nylon 6/66: Nylon 6/66 is a blend of nylon 6 and nylon 66, offering better water resistance than pure nylon 6.

The water resistance of nylon depends on various factors, such as:

• Type of nylon: Some types of nylon exhibit superior water resistance compared to others.
• Thickness: Thicker nylon tends to have better water resistance than thinner nylon.
• Waterproof coating: The application of a waterproof coating can enhance the water resistance of nylon.

7. How to properly maintain water resistant nylon?

To maintain water resistant nylon, it's essential to keep in mind the following guidelines:

• Wash and dry properly: water resistant nylon can be damaged if washed with hot water or machine-dried. It's best to hand wash it using cold water and mild detergent. After washing, allow the item to air dry naturally in a shaded area.
• Avoid exposure to sunlight and high temperatures: Sunlight and high temperatures can degrade the water resistant coating on nylon. Store the product in a cool, shaded place to prevent direct exposure to sunlight.
• Avoid using strong chemicals: Strong chemicals can damage the water resistant coating of nylon. Avoid using cleaning products containing chlorine or acid.

8. Frequently asked questions

Does nylon absorb water?

Nylon is water resistant, so it does not absorb water. When water comes into contact with nylon, it forms droplets and rolls off the fabric's surface. Nylon also has a high moisture-wicking capability, preventing the fabric from becoming waterlogged or retaining sweat.

Can water resistant nylon be recycled?

Yes, water resistant nylon can be recycled. Nylon is a synthetic material that can be recycled into new products. water resistant nylon can be recycled into various items, such as fibers, fabrics, packaging, and other products.

Is biodegradation possible for water resistant nylon?

Water resistant nylon cannot naturally biodegrade. It is a synthetic plastic that contains carbon and hydrocarbon molecules, which are not biodegradable by natural microorganisms. However, water resistant nylon can be biodegraded through chemical or biological treatment processes.

Can water resistant nylon be produced sustainably?

Yes, water resistant nylon can be produced sustainably. There are several ways to produce sustainable nylon, including:

• Using renewable energy for nylon production
• Utilizing sustainable raw materials, such as plant-based oils or recycled plastics
• Reducing waste during the nylon production process

How well does water resistant nylon perform in harsh conditions?

Water resistant nylon performs well in various challenging conditions, including heavy rain, storms, strong winds, and mist. However, it is not completely waterproof and may become permeable under the harshest conditions, such as prolonged submersion in water or exposure to hot water.

How does water resistant nylon compare to other waterproof fabrics?

Water resistant nylon offers similar water resistant properties to other waterproof fabrics like polyester, polyurethane, and vinyl. However, it excels in terms of abrasion resistance and durability compared to these materials.
