Kapok is a natural fiber derived from the seeds of the kapok tree. It is a fluffy, light and soft material that is often used as stuffing in pillows, cushions, and other items that require padding. Kapok is known for its ability to retain warmth and moisture, making it an ideal material for outdoor insulation. It is also hypoallergenic, resistant to water and insects, and biodegradable, making it an eco-friendly choice for many textile applications. Despite its many benefits, kapok is not commonly used for clothing due to its tendency to mat and clump when wet.
