First, let's understand what ice silk is. In fact, there is no specific fabric component called 'ice silk' in textile materials. It is not a specific fabric material but a general term used for one or more materials. Many fabrics that feel cool to the touch are referred to as ice silk fabrics. Ice silk is usually made of synthetic fibers such as polyester, nylon, and spandex.

Next, let's look at the characteristics of polyester, nylon, and spandex fabrics.

Polyester:

A synthetic fiber obtained by spinning polyester, which is formed by polycondensation of a diacid and a diol, belonging to polymer compounds. It was invented in 1941 and is currently the largest variety of synthetic fibers.

Advantages: Sunshade, UV protection, good light resistance, excellent wrinkle resistance and shape retention, strong and durable fabric, wrinkle-free and easy to wash, moisture-resistant, and will not mildew during storage.

Disadvantages: Poor moisture absorption, poor breathability, can feel stuffy when worn, not very breathable, prone to static electricity, and dyeing is more complicated, requiring high temperatures.

Nylon:

Also known as polyamide fiber. It is the first synthetic fiber variety in the world, and due to its excellent performance and abundant raw material resources, it has been widely used.

Advantages: Excellent wear resistance, the best among all fibers, lightweight, low density, good elasticity, and excellent elastic recovery. It also has relatively good moisture absorption among synthetic fibers.

Disadvantages: Slightly poor breathability, prone to static electricity, and not very resistant to heat or light.

Spandex:

The scientific name of spandex is polyurethane fiber, which is an elastic fiber that contains more than 85% polyurethane in its composition. Spandex is generally composed of multiple filaments, usually 10D/filament, though 15D/filament and 20D/filament are now available. Theoretically, the fewer the filaments, the better the evenness of the thread.

Advantages: Good elasticity, can stretch 5-8 times, soft, smooth, and comfortable feel, good stability, not easily deformed, resistant to acids and alkalis, wear-resistant, and durable. It also has good dyeing properties and is not prone to fading.

Disadvantages: Poor moisture absorption, cannot be used to make clothing on its own, needs to be blended with other fabrics, and has poor heat resistance, making it less breathable in summer.

By combining the characteristics of these fabric components, we create what is known as ice silk fabric. Here are two common examples of ice silk fabric compositions:
1. Fabric composition: 87% nylon + 13% spandex
Advantages: Good moisture absorption, excellent wear resistance, elasticity, and strong elastic recovery.

2. Fabric composition: 88% polyester + 12% spandex
Advantages: Good light resistance, strong UV protection, excellent elasticity, durable fabric, and wrinkle-resistant without easy deformation.

The primary goal of sunscreen clothing is to protect the skin from the harmful effects of ultraviolet (UV) radiation. Ice silk typically have a high Ultraviolet Protection Factor (UPF), effectively blocking the penetration of UV rays. In addition, ice silk is thin, soft, breathable, and moisture-wicking. This feature makes ice silk an ideal choice for making sunscreen clothing over other fabrics.

Secondly, the breathability of cooling fabrics is another important reason for choosing them as materials for sunscreen products. In hot summer weather, wearing sunscreen clothing can make people feel stuffy and uncomfortable, which may lead to discomfort or even skin problems. The breathability of cooling fabrics allows for effective sweat evaporation and heat dissipation, keeping the wearer cool and comfortable even in sweltering conditions.

In conclusion, ice silk offer multiple advantages such as UV protection, breathability, quick-drying, and softness, making them a preferred choice for most sunscreen products. MDOG Sunscreen Face Masks are made from ice silk fabric that has undergone strict inspection procedures to provide quality and safety certification. They are free of harmful chemical residues and meet sufficient UPF standards, ensuring they are completely safe for use.
