In the fast-changing internet era, private sale websites attracted an enormous interest from the consumers in especially online marketing of apparel goods. The retailers may garner more benefit if the prior issues for the consumers when they are purchasing apparel products online is known. Reviewing the literature, this study presents the factors in three groups in a hierarchical manner considering the multidimensional aspect of online purchasing of apparel products from private sale websites and then determines the prior issues for the consumers by making pairwise comparisons among these factors using analytical hierarchy process on a sample group of 100 Turkish respondents. The findings revealed that “privacy/security” in terms of online shopping criteria, “product information” in terms of apparel products criteria, and “discount ratio” in terms of private shopping criteria took highest scores of importance when the aspects were analyzed individually. Nonetheless, the parameters regarding the online shopping criteria were found to be more important than the criteria regarding the apparel products and private shopping criteria. In the end, it was also observed that these items that were found to have highest importance were actually corresponding to the risks of the situation.

In this study, fast fashion concept is investigated in order to understand the motivations of the consumers that make them adopt these products because of their willingness for the innovativeness. The relationship between the motivational factors which were named as “Social or status image” and “Uniqueness” as expressions of individuality, “Conformity” and the willingness for “Innovativeness” is analyzed using a conceptual model. Exploratory factor analysis, confirmatory factor analysis and structural equation modeling were used to analyze and validate the model. The data used for the study was obtained from 244 people living in Turkey. The findings showed that the motivational factors “Social or status image” and “Uniqueness” as expressions of individuality are influential on the consumers’ willingness for “Innovativeness”.

The use of clean water in textile finishing is both common and very expensive. Effluent water subjected to advanced methods of physical, chemical, and biological treatment could be used for this purpose. However, information obtained from industry and the literature shows that effluent water obtained from different finishing processes may be reused without being totally purified. In this paper, a method is proposed to determine the viability of reusing effluent water obtained from different textile finishing processes of cotton fabrics after just basic treatments. These treatments include; filtering, airing, pH regulating and ion exchange. Effluent water obtained in different textile finishing processes was analysed in terms of pH value, COD (Chemical Oxygen Demand), SS (Suspended Solids), colour, hardness and conductivity. Effluent water for treatment and the process where the treated water was reused were determined by means of the proposed method, based on a multiple criteria decision making approach. A laboratory scale trial was conducted to investigate the efficiency of treatment.

In this study, the effects of draft ratios on the properties of vortex spun yarns were investigated. 100% viscose drawing slivers of three different counts (3.94 ktex, 3.19 ktex and 2.68 ktex) were spun into yarns with a count of 14.76 tex while keeping all other spinning conditions constant. The yarn samples were evaluated on the basis of yarn irregularity and imperfections, as well as hairiness and tensile properties. In addition, a 3rd passage draw frame sliver with a yarn count of 3.19 ktex was spun into yarns of 14.76 tex using two different delivery speeds: 350 and 400 m/min. The significance of independent variables and their interactions for the physical properties of the yarn were tested statistically at a 95% level of confidence.

Do badań wybrano taśmy z włókien wiskozowych o trzech masach liniowych: 3,94 ktex, 3,19 ktex, 2,68 ktex wytwarzając przędze o masie liniowej 14,76 tex. Wytworzone próbki badano analizując ich nierównomierność, ilość zgrubień pocienień i nopów oraz włochatość. Dodatkowo zastosowano trzeci stopień rozciągu dla wyprzędzenia z taśmy 3,19 ktex przędzy o masie liniowej 14,76 tex stosując dwie prędkości zasilania: 350 m/min i 400 m/min. Wpływ poszczególnych parametrów procesu badano statystycznie na poziomie ufności 95%.

W artykule zidentyfikowano trendy i wpływy światowej gospodarki na turecki przemysł przędzalnictwa bawełny. Oparto się na liczbach dotyczących zainstalowanych mocy produkcyjnych, całkowitej produkcji, jak również kosztów produkcji i handlu zagranicznego, uwzględniając dłuższe przedziały czasowe oraz konkurencyjne możliwości przemysłu. Wartości importu i exportu były rozpatrywane w odniesieniu do głównych rywali. W ten sposób uzyskano przegląd stanu aktualnego oraz przewidywany rozwój tureckiego przemysłu bawełniarskiego.

This article presents general characteristics and current applications of regenerated bamboo fibre in the textile industry. In the experimental part of the study, 100% regenerated bamboo yarns of six different counts (11.8, 14.8, 16.4, 19.7, 24.6 and 29.5 tex) were produced from bamboo fibre using ring yarn spinning technology. Subsequently, the physical parameters of related yarns produced in spinning mill conditions were tested, and the results were evaluated according to the parameters of 100% viscose rayon, as well as 100% carded and combed ring spun yarn in Uster statistics. In this way, the aim was to state the strength and weakness of bamboo fibre and to predict its future in the textile industry

Przedstawiono ogólną charakterystykę regenerowanych włókien bambusowych oraz możliwości ich zastosowania w przemyśle tekstylnym. Część eksperymentalna przedstawionych badań dotyczyła regenerowanych włókien bambusowych o sześciu masach liniowych (11,8; 14,8; 16,4; 19,7; 24,6 i 29,5 tex). Włókna przędziono na przędzarce obrączkowej, a następnie włókna otrzymane w warunkach określonej przędzalni były badane a wyniki porównywano ze 100% wiskozową przędzą ciągłą oraz zgrzebloną i czesaną przędzą obrączkową, biorąc jako odniesienie charakterystyki Ustera. Badania pozwoliły na określenie zalet i wad włókien bambusowych i możliwości ich zastosowania w przemyśle włókienniczym.
