Design of a Novel Filament with Vapor Absorption Capacity Without Creating Any Feeling of Wetness

Abstract

The aim of this study is to design and develop a novel filament that can absorb water vapor but does not cause any feeling of wetness to the person who touches it. Thus, a polypropylene fiber which absorbs no water vapor (0%) may be used as an outer surface while SAP (super absorbent polymer) may be used as a filler placed into the cavity of the filament in order to absorb the required excessive amount of water vapor. It has been proven that the developed novel filament with SAP filler could absorb water vapor, without creating any feeling of wetness. It has been observed that while a filament with SAP absorbs 8% water vapor providing a dry sense on the outer surface of the filament, a filament without SAP absorbs 0% water vapor. All samples dried in about 20—30 minutes following the first water absorption test. The dry cleaning process caused a decrease in water vapor absorption capacity at a ratio of up to 50%. The amount of SAP, the number of filaments in the filament bundle and the covering density on the filament bundle affected the absorption capacity at statistically significant levels.
