Öğe A Comparative Analysis of Towels Produced From Twisted and Twistless Cotton Pile Yarns in Terms of Absorptive Capacity and Flexural Rigidity(Inda, 2015) Sekerden, FilizThe 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.Öğe Effect of Fabric Weave and Weft Types on the Characteristics of Bamboo/Cotton Woven Fabrics(Lukasiewicz Research Network - Lodz Institute Of Technology, 2011) Sekerden, FilizThis paper presents a study of some physical and mechanical properties of bamboo, cotton and bamboo/cotton woven fabrics that are commonly used in the textile industry. 4 different weave type fabrics were produced under industrial conditions by using 100% bamboo of 36.90 tex as the weft yarn, three different mixes of bamboo/cotton and 100% cotton yarn. Unevenness, breaking strength-strain and number analyses were carried out on the weft and warp yarns. Tests of dimensional stability, air permeability, water absorption, abrasion resistance and bending rigidity were applied to the fabrics produced. The effect of the yarn and weave types on the physical and mechanical properties of the fabric were examined statistically. It was found that the weave type affects the physical and mechanical properties of the fabric more than the fiber mix and type in the weft yarn.Öğe EFFECT OF PILE YARN TYPE ON ABSORBENCY, STIFFNESS, AND ABRASION RESISTANCE OF BAMBOO/COTTON AND COTTON TERRY TOWELS(Soc Wood Sci Technol, 2012) Sekerden, FilizThis study compared absorbency, stiffness, and abrasion resistance characteristics of bamboo/cotton and cotton terry towels. Bamboo/cotton terry towels were woven with bamboo pile yarn, which has been commonly used in textiles in recent years, whereas cotton terry towels were woven with cotton pile yarns. Desized woven terry towels without dye or any further finishing treatments were produced under industrial conditions. Effects of pile yarn type and pile height on physical and mechanical properties of fabrics were compared using analysis of variance. Design Expert 6.01 (Stat-Ease, Inc., Minneapolis, MN) was used for statistical analyses. It was found that abrasion of towels with bamboo pile yarn was higher than that of towels with cotton pile yarn at high abrasion cycles, whereas stiffness of bamboo/cotton towels was lower than :hat of cotton towels. Also, it was found that sinking time of terry towels with cotton pile yarn was longer than that of towels with bamboo pile yarn.Öğe Effect of pile yarn type on absorbency, stiffness, and abrasion resistance of bamboo/cotton and cotton terry towels(2012) Sekerden, FilizThis study compared absorbency, stiffness, and abrasion resistance characteristics of bamboo/ cotton and cotton terry towels.

This study examines the effects of weft yarn types and weave types on the surface electrical resistivity and vertical electrical resistances of metal/cotton electrically conductive woven fabrics. Fabrics were produced using four different types of stainless steel/cotton weft yarns. Effects of weave type and weft yarn type on the electrical resistances of the fabrics were examined using analysis of variance (ANOVA). It was concluded that the weft yarn type and weave type significantly affect the surface electrical resistivity and vertical electrical resistance of the fabrics at a significance level of 0.05.Öğe Investigation on the Unevenness, Tenacity and Elongation Properties of Bamboo/Cotton Blended Yarns(Inst Chemical Fibres, 2011) Sekerden, FilizThis study investigated the effect of bamboo fiber, which has recently begun to be commonly used in textiles, on the performance properties of yarn. The present study used 100% bamboo yarn of 19.68 tex, which was ring-spun under industrial conditions, bamboo/cotton with varying blend ratios and 100% cotton yarns. The unevenness, tenacity and elongation at break of the yarns were measured. The effect of yarn type on these properties was analysed by analysis of variance and the Tukey test, which were used to determine statistically significant differences between yarn types. The results indicated that the ratio of bamboo fibre in the blend had an effect on the properties of yarn.Öğe INVESTIGATION THE EFFECTS VARIOUS WEAVING FACTORS ON WARP TENSION(Ege Univ, 2010) Sekerden, Filiz; Celik, NihatIn this study, considering that the tension variations affect the quality of fabrics and weaving performance or efficiency, the effect of well density, well number, weave type and measuring region of warp tension on warp tension have been investigated. For this purpose, the fabrics were woven in seven different pattern constructions with four different well densities using two different well in count. Warp tensions have been measured under running conditions of the loom. Hence, the relationship between the tension and weaving parameters determined has been given on the base of this study. Statistical analysis was made by using Design-Expert 6.0.1 package programme. The effect of the factors, weave type, well number, well density and measuring region of warp tension, has been investigated by using varyans and regression analysis. The regression equations have been determined for all the weave types. It is concluded that weave type, measuring region, well density, well number, weave type x measuring region, measuring region x well number factors effect the warp tension statistically significant level (p<0.001).Öğe Status of Textile and Clothing Imports and Exports in Turkey(Inst Chemical Fibres, 2011) Sekerden, FilizThe textile industry is a sector which has an important place in Turkey's economy. In this paper, import and export figures of Turkish textiles between 2004 and 2008, as well as their global status are examined. It is understood that many exported textile products are imported as well, and many imported textile products can also be produced in Turkey. It is estimated that preventing the importation of those textile products which can be produced in Turkey shall decrease textile imports, which in turn shall reduce Turkey's dependence on other countries and improve Turkey's competitive power.Öğe Status of textile and clothing imports and exports in Turkey(Sciendo, 2011) Sekerden, FilizThe textile industry is a sector which has an important place in Turkey's economy.
