An investigation on colour analysis and fastness properties of the denim fabric dyed with a different method

Denim is a fabric which is produced by weaving dyed warp and weft yarns. The most important feature of denim fabric is the colour which is created by indigo dyeing. The mere reason for this special look is magical ''Indigo'' which the warp yarns are dyed with. In this study, an innovative dyeing method was applied by adding an extra step to indigo-sulphur dyeing. The main target was achieving the unique colour transitions and appearances. At the scheduled research, colour analysis and fastness properties were evaluated

Comfort and performance properties of raised and laminated denim fabrics

In this study, denim fabrics manufactured using standard processes were selected as reference fabric and subjected to mechanical and chemical finishing treatment. The effects of the two finishing treatments on the comfort and performance properties of the fabric were investigated. The test samples were the reference fabric, raised fabric and laminated fabric. The comfort tests were for fabric thickness, air permeability and water vapor permeability. The performance tests were for tensile strength, fabric stiffness, tearing strength and fastness. Colour and microscopic image analyses of the samples were also made and evaluated. Raising and lamination improved the thermal resistance properties, whereas raising increased air permeability. Evaluating the performance, fastness and colour properties of the raised and laminated fabric samples did not reveal any significantly negative outcomes. Raising can be recommended for use on the condition that seasonal variations be considered, since it creates comfortable denim fabrics with improved thermal resistance and air permeability. © 2016, Institute of Biopolymers and Chemical Fibres.

An experimental application on denim garment to give thermal regulation property

In this context, the influence of ‘phase change material (PCM) finishing on denim jeans’ on thermal regulation and other selected properties was investigated. Denim garments were treated with microcapsulated PCM in various concentrations given in bath and by dipping, followed by the curing process. Differential scanning calorimeter tests were applied to denim fabrics. Morphology of microcapsules was characterized by scanning electron microscopy analyses and color analyses of the garments were done and evaluated. © 2016 The Textile Institute

Investigation of some comfort properties of fabrics laminated with different types of membranes

The aim of this study is to determine and evaluate some comfort properties of laminated fabrics obtained with different membranes. In the study, 100% PES woven fabric was laminated using membrane materials as PU (polyurethane), PES (poliester) and PTFE (polytetrafluoroethylene). Water repellent finishing process was applied to these fabrics and some comfort tests of the fabric were carried out in two groups. These groups are; Group 1, subjected to lamination after the application of water repellent finishing process; group 2, subjected to water repellent finishing process after lamination process. The comfort tests included water repellent, air permeability, water impermeability, and water vapor transmission tests. The obtained results from experimental studies were compared with graphics and thus interpreted. In conclusion, it could be recommended to apply water repellent processes after lamination, in contrast to traditional method using water repellent process prior to lamination

An experimental study on sewability properties of 100% cotton denim fabrics

This paper presents an experimental study of the sewability properties of %100 cotton fabrics. In this study, denim fabrics woven with three different weft densities and three different weft count. Two different finishing processes were applied to all fabric samples. Therefore 18 samples having different specifications were obtained. Sewing needle penetration forces were determined for these fabrics for sewability properties. Also bending rigidity and air permeability tests were determined for these fabrics for investigated the relationship between sewability properties. This study investigated the effects of weft density, weft count, finishing process, bending rigidity and air permeability on the sewability properties of denim fabrics. © 2018 Ege Universitesi.
