Determining the effect of enzymatic pretreatment on the low temperature dyeability of polyamide fabrics
(Wiley, 2022)In this study, by pretreating polyamide 6/elastane knitted fabrics with serine-type protease enzyme, the aim was to reduce dyeing temperatures. It is known that the elasticity of elastane fibres is damaged in dyeing at ... -
Distinguishing yak and cashmere fibers from each other to prohibit mislabeling through microscopic and spectroscopic analysis
(Taylor and Francis Ltd., 2023)Since yak and cashmere fibers show very similar properties and yak fibers are considerably cheaper than cashmere, it is an important issue that yak is used instead of cashmere in the industry and the final product is sold ... -
The effect of core-sheath proportion on the characteristics of hollow yarns: part I mechanical properties
(Taylor and Francis Ltd., 2018)In the scope of this study, core yarns in the yarn count of 59 tex were produced by using cotton, viscose, wool, and polyester fibers in the sheath and different ratios of polyvinyl alcohol (PVA) in the core. After completion ... -
The Effect of Dyeing and Mohair/Wool Blend Ratio on Fabric Physical Properties
(Taylor & Francis Inc, 2020)In this study, dyeing effects on the physical properties of blended fabrics containing different ratios of wool and mohair fibers were investigated in detail. Six types of fabrics were produced by using 100% wool yarns and ... -
Effect of the ozonation process on the dyeability of mohair fibres
(Wiley-Blackwell, 2011)This work has focused on the use of ozonation in order to improve the dyeability of mohair fibres. The study was carried out using a known concentration of ozone and involved process parameters such as wet pick-up, level ... -
The effect of using alpaca and silk instead of wool in weft yarns on the woollen fabric properties
(Taylor & Francis Inc, 2019)In this study, the effect of using silk or alpaca weft yarns on fabric properties and dyeing behavior in the production of woollen woven fabrics was investigated. Therefore, three different fabric types with two different ... -
Identification of novel genetic variants for KAP1.1, KAP1.3 and K33 genes in some of indigenous goat breeds of Turkey
(Scientific Technical Research Council Turkey-Tubitak, 2021)The animal fibres such as mohair, cashmere and cashgora have a complex structure and affected by genetic variation of keratin associated protein genes as KAP 1.1 (Keratin Associated Protein 1.1, formerly known as B2A), ... -
Investigation of drying kinetics of viscose yarn bobbins
(2011)This study is concerned with the investigation of the suitability of several empirical and semi-empirical drying models available in the literature to define drying behavior of viscose yarn bobbins. For this purpose, ... -
Investigation of static electricity amount of wool and wool blend fibers depending on machine speed and fiber blend
(Chamber of Textile Engineers, 2017)Fibre-fibre and fibre-metal frictions lead to static electricity on 100% wool and wool blended fibres during the yarn production due to the triboelectric charging. In this study, the variation of the static electricity ... -
THE INVESTIGATION OF THE EFFECT OF CHEMICAL MODIFICATION WITH CHITOSAN TO PROVIDE SINGLE BATH DYEABILITY OF NYLON / COTTON BLEND FABRICS
(Chamber of Textile Engineers, 2022)In this study, it was aimed to make each fiber components dyeable with a single dyestuff so that nylon / cotton blend fabrics can be dyed in the same bath. For this purpose, it was aimed to make each of these fibers dyeable ... -
