We all know that warmers are very popular in winter outdoor sports, so non-woven fabric and breathable film are two materials commonly used in warmers. They really have some differences in properties and uses.
1. Material Structure:
Non-woven fabric is textile formed from fibers through mechanical, chemical or thermal methods, and have a structure of intertwined fibers; breathable film is a material with microporous structure that achieve breathability through tiny pores sex.
2. Breathability:
Non-woven fabric is generally not breathable because its fibers are tightly interviewed and cannot easily allow air to pass through. Breathable film has a microporous structure that allows gas and water vapor to pass through, thereby providing breathable performance.
3. Moisture Barrier:
Non-woven fabric can block the penetration of moisture to a certain extent, because the tight structure between its fibers can block the passage of liquid; while although breathable film is breathable, they usually have certain moisture barrier properties and can prevent the penetration of liquids.
4. Functional Characteristics:
Non-woven fabric can provide certain thermal insulation properties and physical protection, but are not breathable; breathable film is mainly used to achieve breathability and moisture regulation, and can prevent overheating and moisture accumulation.
To sum up, non-woven fabric is mainly used to provide physical protection and thermal insulation properties, and breathable film is mainly used to achieve breathability and moisture regulation. In air-activated warmers, non-woven fabric is often used as outer materials to provide protection and warmth, while breathable film can be used as inner materials to achieve breathability and moisture regulation to improve comfort.
