A Guide to Natural Fibers: Discover Their Unique Qualities and Choose

Natural fibers, which are widely used in our clothing and everyday lifestyle items, are materials that literally come from plants and animals in nature. Unlike synthetic fibers, they are gentle on both the skin and the planet, and in recent years they have been attracting renewed attention.

Representative natural fibers can mainly be divided into plant-based fibers and animal-based fibers. Let’s take a closer look at each type and its characteristics.

1. Plant-Based Fibers

These are fibers obtained from plant seeds, stems, leaves, and other parts. They are known for excellent moisture absorption, breathability, and a pleasant feel against the skin.

・Cotton

・Characteristics: Cotton is the most widely used natural fiber and is known for its softness and comfortable feel against the skin. It has excellent water absorption and moisture absorption, as well as high breathability, making it ideal for everyday clothing such as underwear and T-shirts because it absorbs sweat well. It is also heat-resistant and easy to wash. On the other hand, it can be slow to dry, prone to wrinkles, and likely to shrink.

・Main uses: T-shirts, underwear, towels, denim, bedding, and more

・Linen

・Characteristics: Linen is a fiber made from the stem of the flax plant and is known for its distinctive crisp texture. It is extremely durable, has excellent moisture absorption and quick-drying properties, and offers outstanding breathability, making it ideal for Japan’s hot and humid summers. It also becomes stronger when wet. Linen tends to wrinkle easily, but those wrinkles are often enjoyed as part of its natural character.

・Main uses: Shirts, dresses, summer clothing, towels, curtains, tablecloths, and more

・Hemp

・Characteristics: Hemp is a fiber made from the stem of the hemp plant. Like linen, it is a type of bast fiber, but it is even more durable and has excellent water absorption. It also has strong antibacterial and deodorizing properties, with a distinctive firmness and resilience. Another feature is that it becomes softer and more comfortable against the skin the more it is used.

・Main uses: Casual wear, bags, rope, and more

2. Animal-Based Fibers

These are fibers obtained from the hair of animals such as sheep and goats. They are known for excellent warmth retention, moisture absorption, and a soft, flexible feel against the skin.

・Wool

・Characteristics: Wool refers broadly to fibers made from sheep’s fleece. It has extremely high warmth retention and is essential for winter clothing. Because it offers excellent moisture absorption and release, it is less likely to feel stuffy even when you sweat, while still maintaining warmth. It also has natural antibacterial and odor-resistant properties. In particular, merino wool is known for having extremely fine fibers among wool types, making it less itchy and very comfortable against the skin.

・Main uses: Sweaters, coats, suits, socks, underwear, activewear, and more, especially merino wool

・Cashmere

・Characteristics: Cashmere is made from the soft hair of cashmere goats. Although it is a type of wool, it is a premium fiber often called the “jewel of fibers.” It is extremely delicate, with a meltingly smooth feel against the skin, and is known for being lightweight while offering excellent warmth retention. Its elegant sheen is also appealing, but because it is a delicate material, it requires careful care.

・Main uses: Luxury sweaters, stoles, coats, and more

・Silk

・Characteristics: Silk is a fiber made from silkworm cocoons and is known for its beautiful luster and smooth feel against the skin. It has excellent moisture absorption, moisture release, and warmth retention, making it cool in summer and warm in winter. Because its composition is close to that of human skin, it is considered gentle and less irritating, even for sensitive skin. However, it is delicate and vulnerable to UV rays, so careful maintenance is necessary.

・Main uses: Blouses, innerwear, pajamas, scarves, kimono, and more
