Yes, the shiny nylon jacket with polyurethane coating is likely waterproof. Polyurethane coating is commonly used to make fabrics waterproof by creating a barrier that repels water. This coating is often used on outdoor gear and rain jackets to provide protection from the elements. Therefore, it is safe to assume that the shiny nylon jacket with polyurethane coating is indeed waterproof. **

Waterproof nylon is a type of fabric that has been treated with a special coating or laminate to make it completely impervious to water, meaning that no water can penetrate the fabric. On the other hand, water-repellent polyester is a fabric that has been treated with a coating to make it resistant to water, causing water to bead up and roll off the fabric rather than being absorbed. While both fabrics offer some level of water resistance, waterproof nylon provides a higher level of protection against water compared to water-repellent polyester. **

The waterproof PU or rubber coating on nylon rainwear is located on the inside to protect it from wear and tear. When the coating is on the outside, it is more susceptible to damage from abrasion, UV exposure, and other environmental factors. Placing the coating on the inside also helps to maintain the appearance of the rainwear, as it is less likely to become scuffed or discolored. Additionally, having the coating on the inside provides a smoother and more comfortable feel against the skin. **

Nylon is produced through a chemical process called polymerization. It starts with the extraction of raw materials such as coal, water, and air to produce the basic building blocks for nylon. These building blocks are then combined and reacted under controlled conditions to form long chains of nylon molecules. The resulting nylon polymer is then processed further to create fibers, filaments, or plastics that are used in various products such as clothing, carpets, and packaging. **

Nylon strings are a type of string used on musical instruments, particularly on classical and flamenco guitars. They are made from nylon, a synthetic polymer material, and are known for their smooth feel and warm, mellow tone.

A pen that works well on nylon is a permanent marker or a fabric marker. These types of pens have ink that is designed to adhere to various surfaces, including nylon. When using a pen on nylon, it is important to test it on a small, inconspicuous area first to ensure that it does not bleed or smudge. **
