As a result of the literature review, it was observed that previous studies concentrated mainly on investigating the water absorption properties of towel fabrics, but limited studies analyzed air permeability properties of towel fabrics. The purpose of this study is to investigate the air permeability of bamboo / cotton and cotton towels produced with different pile heights and to analyze the effect and importance level of pile fiber type and pile height in these two types of towel fabrics. The paper presents an investigation of the air permeability ability of towel fabrics with respect to pile height and pile fiber type. Towel fabrics were produced under industrial conditions. 100% bamboo and 100% cotton yarns were used as pile yarns, while 100% cotton yarn was used as weft and ground warp yarn. The effect of pile fiber type and pile height on the air permeability properties of fabrics was compared using analysis of variance (ANOVA). The Design Expert 6.01 program was used for statistical analyses. It was found that air permeability of bamboo/cotton towel fabrics was higher than 100% cotton towel fabrics and the air permeability of both types of towels decreased as pile height increased.

The study compares cotton towels produced from twisted and twistless cotton pile yarn. The towels were manufactured with different weft density, different weft yarn counts, and different pile heights. The water absorptive capacity, absorbency time and flexural rigidity properties of twisted pile towels were compared with those of twistless pile towels. The test results were evaluated using statistical analysis. Effects of twisted and twistless pile yarn, pile height, weft density, and weft yarn count on absorptive capacity, absorbency time, and flexural rigidity of fabrics were examined using analysis of variance (ANOVA). The results indicate that the towels woven with twistless pile yarns have greater absorptive capacity, longer absorbency time, and lower flexural rigidity than towels woven with twisted pile yarns.
