Frequently Asked Questions | FAQs

What is seed fibre?

Seed fiber, also known as seed hair, is a type of natural fiber that is derived from the seeds of certain plants. These fibers are often long and thin, with a high tensile strength and a smooth, lustrous surface.
Examples of seed fibers include cotton, kapok, and coir. Cotton, one of the most common seed fibers, is used extensively in the textile industry to produce a wide range of products such as clothing, bedding, and towels. Kapok, a silky fiber that comes from the seeds of the kapok tree, is used in the production of pillows, cushions, and upholstery. Coir, which comes from the outer husk of coconut seeds, is used in the production of rope, mats, and other household items.
Seed fibers are often preferred over synthetic fibers as they are biodegradable and environmentally friendly. They are also hypoallergenic, making them a good choice for people with sensitive skin. Additionally, seed fibers have good moisture absorption and ventilation properties, which makes them comfortable to wear in warm weather.

What are seed hair fibre examples?

Some examples of seed hair fibers are:

1)Cotton: It is the most common and widely used seed hair fiber in the textile industry. Cotton fibers are soft, breathable, and absorbent, making them ideal for making clothing, towels, bed sheets, and other textile products.

2)Kapok: It is a silky, lightweight fiber obtained from the seeds of the kapok tree. Kapok fibers are hollow, which makes them an excellent insulator, and they are often used to fill pillows, mattresses, and life jackets.

3)Coir: It is a coarse, stiff fiber that is extracted from the outer husk of coconuts. Coir fibers are strong, durable, and resistant to saltwater, making them ideal for making ropes, mats, and other products used in maritime applications.

4)Milkweed: It is a soft, silky fiber that comes from the seeds of the milkweed plant. Milkweed fibers are often used in the production of insulation, pillows, and other products that require a soft and lightweight material.

5)Cashmere: It is a soft and luxurious fiber that comes from the undercoat of cashmere goats. Cashmere fibers are lightweight, warm, and very soft, making them ideal for making sweaters, shawls, and other high-end garments.

These are just a few examples of seed hair fibers. There are many other types of natural fibers that come from seeds, such as flax, hemp, and sunflower, each with their unique properties and applications.
