For most of human existence it was not possible to spin kapok into a yarn so the fibre has mostly been used as a filling in pillows. Gebr. Otto has developed a special spinning technique and in 2004 we finally managed to offer a premium yarn made with kapok in a blend with cotton.
Kapok is a cellulosic hollow fibre, about 2-4 cm in length, containing about 80% of nothing but air and is 6 times lighter than cotton. The kapok fibre has excellent temperature regulation properties and a soft and silky handle justifying its alternative name of ‘vegetable silk’ or ‘vegetable cashmere’. The fibre is coated with a natural water repellent wax and absorbs almost no humidity.
The kapok tree is a tropical tree, native to Indonesia, Java, Malaysia, West Africa, the Caribbean and the northern South America. The kapok tree is not cultivated on plantations but is found as a natural tree growing in wild or semi wild locations. It is totally free from agricultural pesticides and fertilizers. The kapok fibre is 100% biodegradable.
Piumafil® yarn is available in a blend of 85% cotton and 15% kapok.
