Hollow fibre

Other names: Hollow fibers

Harm score: 2 (Derivatives of natural substances)

Hollow fiber, often referred to as hollow fibers, is a product with unique properties that are widely used in various industries. Its main advantage is its great lightness, with a high degree of insulation and the ability to hold large amounts of air. It is this combination of properties that makes hollow fibres the ideal material for the production of, for example, outdoor clothing, sleeping bags or down jackets. Compared to solid fibres, hollow fibres have much better insulating properties and can also wick away moisture.

Recently, hollow fibres have also started to be used in medicine. Thanks to their specific properties, such as the ability to form special layers on their surface, they can be used, for example, in the manufacture of medical dialysis equipment. This prevents the transfer of harmful substances into the patient's blood, while at the same time allowing the effective removal of toxic products of metabolism. In addition, hollow fibre is used in the water filter industry, where it helps to effectively remove unwanted substances from water. Another important sector where hollow fibre finds its application is the construction industry. It is a component of insulation materials and thus provides protection for buildings against heat and sound penetration. Such a wide range of applications demonstrates the versatility and benefits of hollow fibres in various fields of human activity.
