Analysis of Dynamic Water Absorption Phenomenon in Pile Fabrics

Abstract

This paper presents the investigations into wetting phenomenon of linen/ cotton terry fabrics with different pile height and affected by different impacts or finishing operations. The samples of terry fabrics were manufactured using unbleached linen warps and base was made of cotton ground warps and wefts. 24 different terry linen/cotton fabrics constructions impacted by various impacts - water/heat/mechanical/chemical were investigated. The terry fabrics with linen pile warps are qualified by high absorption ability and peculiar process of water absorption from the start moment when the liquid drop falls on the fabric‘s surface until the last moment when the drop is absolutely absorbed by the material. The behaviour of fabric in contact with water drop depends on terry fabric‘s structural characteristic, kind of impact and it‘s lasting. The pile height is very important for the wetting phenomenon. By using the suggested method it is possible to determine the dynamics of absorption process of the fabric and to evaluate as well as to interpret absorption progress in time.
