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 — making it one of the main yarn choices for crafting graduated compression socks.

02

Elastane (Spandex) — Lycra

Polyurethane fiber, commonly known as spandex, is a 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 extend 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 plays a pivotal role, providing essential elasticity and ensuring a comfortable, consistent fit.

03

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 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 also has natural antibacterial properties that help inhibit the growth of odor-causing bacteria. This versatile material can be used as a primary or auxiliary yarn and blends seamlessly with cotton, nylon, and acrylic — making it one of the most popular choices for crafting graduated compression socks.

Bamboo charcoal fiber

Bamboo charcoal fiber belongs to a category of natural, environmentally friendly, regenerated fibers. It's 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 contributing to a reduced environmental burden.

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

Bamboo charcoal fiber yarn can serve as a main or auxiliary yarn and blends seamlessly with cotton and nylon to enhance fabric smoothness and drapability. In graduated compression sock design, it's common to knit the toe and heel areas using bamboo charcoal fiber yarn to maximize deodorizing and antibacterial effects exactly where they're needed most.

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 isn't heat-resistant, so high-temperature drying and washing should be avoided.

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

06

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, though it decomposes at high temperatures. It offers high strength, durability, and quick drying. Despite traditionally feeling rigid and having low water absorption, advancements in textile technology have steadily improved its comfort. It does tend to generate static electricity in dry climates, which is why nylon remains more popular in those regions. Recycled polyester — such as recycled PET fiber — is an eco-friendly option made from repurposed materials like bottles and old clothing.
