Main Fibers Used in Graduated Compression Socks

Fibers play a crucial role in developing high-quality compression socks, influencing aspects such as wearing comfort, structural thickness, and functionality. In light of growing environmental consciousness, consumers increasingly prioritize using eco-friendly products. We invite you to delve into the main fibers utilized in graduated compression stockings and their distinctive characteristics, focusing on environmentally friendly options.

Combed Cotton Fiber

Combed cotton is a natural fiber that undergoes a meticulous process to eliminate short fibers and impurities measuring less than 10mm from conventional cotton yarn using a combing machine. This process results in a substantially neater, longer fiber. Combed cotton yarn, as a result of this meticulous combing, boasts a smoother, finer texture, and increased durability compared to standard cotton yarn. It stands as one of the main yarn choices for crafting graduated compression stockings.

Elastane (Spandex)-Lycra 

Polyurethane fiber, commonly known as Spandex, is a type of synthetic fiber renowned for its elasticity, with Lycra being its most well-known brand. Invented by DuPont in 1958, Lycra has become a staple in hosiery yarns due to its exceptional stretchability—it can be extended to six times its original length and then revert to its initial state. This synthetic elastic fiber enhances the properties of both natural and artificial fabrics, contributing to improved draping, appearance, and comfort. In functional socks, LYCRA fiber plays a pivotal role, providing essential elasticity and ensuring a comfortable fit.

Merino Wool Fiber

Merino wool, derived from fine wool merino sheep, is a natural fiber prized for its exceptional properties. With a water absorption rate six times higher than that of man-made fibers, Merino wool offers excellent temperature regulation and high breathability. In colder climates, it provides warmth while effectively wicking away moisture, reducing the discomfort associated with prolonged sweating on the feet. Rich in keratin, Merino wool boasts antibacterial properties, which help inhibit the growth of odor-causing bacteria. This versatile material can be used as both the primary or auxiliary yarn, and it blends seamlessly with cotton, nylon, and acrylic, enhancing the functionality of fabrics. Merino wool stands as one of the most popular choices for crafting graduated compression stockings, thanks to its remarkable attributes.

Bamboo Charcoal Fiber

Bamboo charcoal fiber belongs to a category of natural, environmentally friendly, regenerated fibers. It is produced by subjecting bamboo to high temperatures to create bamboo charcoal, which is then finely ground using precision technology and incorporated into the fiber. Bamboo grows rapidly and requires minimal management, making it easily decomposable by natural organisms and thus contributing to the reduction of environmental burden.

Bamboo charcoal fiber yarn is infused with minerals and possesses numerous beneficial properties such as far-infrared emission, antibacterial qualities, odor elimination, UV protection, excellent breathability, and wearing comfort. Its deodorizing capabilities stand out among functional yarns, earning it the nickname "breathing fiber."

Bamboo charcoal fiber yarn can serve as both the main or auxiliary yarn and blends seamlessly with cotton, and nylon to enhance fabric functionality, including smoothness and drapability. In the design of graduated compression stockings, it is common to knit the toe and heel areas using bamboo charcoal fiber yarn to maximize deodorizing and antibacterial effects.

Nylon fiber 

Nylon, the world's first fully synthetic fiber, is also known as polyamide fiber. Its strengths include durability, wrinkle resistance, smoothness, and resistance to insects and mildew. However, it is not heat-resistant, so high-temperature drying and washing should be avoided.

Nylon's quick-drying nature makes it convenient for laundering, but it may not effectively wick away sweat. It can be blended with other fibers to enhance breathability and moisture-wicking properties.

※ Recycled Nylon: This eco-friendly fiber is created by reprocessing discarded nylon materials, resulting in a sustainable alternative.

Polyester fiber 

Polyester fiber, one of the three major man-made fibers alongside nylon and spandex, is known for its resistance to acid and alkali but decomposes at high temperatures. It boasts high strength, durability, and quick drying. Despite traditionally feeling rigid and having low water absorption, advancements in textile technology have improved its comfort. However, it tends to generate static electricity in dry climates, making nylon more popular in such regions. Recycled polyester, like Recycled PET Fiber, is an eco-friendly option made from repurposed materials like bottles and old clothes.
