Konfeksiyon ürünlerini oluşturan malzemelerin farklı çekmesi, ürünün kalitesini etkileyen önemli bir faktördür ve onun etkisi yeterince araştırılmamıştır. Bu çalışmada; üst kumaş ile yapışkanlı teladan (ara astar) oluşan birleşmeyi oluşturan malzemelerin farklı boyutsal çekmesinin, birleşmenin kalitesine olan etkisi deneysel olarak araştırılmıştır. Bunun için aynı yapıştırıcı madde ile kaplanmış, fakat aynı koşullarda farklı boyutsal çekme gösteren kumaşlardan üretilmiş iki çeşit yapışkanlı tela ve aynı üst kumaştan fiksaj (yapıştırma) yardımıyla oluşturulmuş yapışkanlı birleşme numuneleri kullanılmıştır.

The effect of structural difference on the drying properties of various knitted fabrics was evaluated in this study. Drying time and water absorption behavior of various single and double jerseys knitted structures were measured. The relation between drying time and water absorption percentage to the fabric thickness, tightness factor and areal weight was statistically analyzed. Strong correlation was found between drying time and the studied parameters. A new parameter "fabric linear weight" was also derived from the studied parameters in order to model the drying time of knitted fabrics mathematically. When drying time was considered, it was found that pique knit dried faster, while it took longer time to dry the three-thread fleece knit. On the other hand, the water absorption percentage of eightlock sample was the highest among all samples. A new drying test approach was also proposed to measure the static drying time of knitted fabrics capable of comparing the effect of different knitted structures

Due to its stiffness, fragility and inelasticity, chicken feathers are not considered a valuable material and are mostly industrial waste, the volume of which is increasing. Therefore, chicken meat producers are trying to get rid of them in every possible way. In recent years, instead of getting rid of chicken feathers, research has been carried out towards using their wonderful properties from nature. Among these studies, a special place is occupied by the production of fibers from chicken feathers, which could be used in the textile industry. The presented work concerns the development of a mechanized method for the production of fiber from chicken feathers on an industrial scale. The proposed method is based on the separation of the fibrous part of the feather from the stem of the feather by mechanical cutting using an aerodynamic disperser. With this method, protein fibers with many valuable properties have been obtained, the weight of which is half that of chicken feathers. In addition to these fibers, called chicken feather fibers, a feather stalk is obtained as a by-product, which, due to its lightness and strength, is a suitable raw material for the production of composites. In this work, the properties of the products obtained by the above-mentioned method were studied, and it was determined that the materials obtained as a result of processing the produced chicken feathers are raw materials suitable for industrial use. The production parameters of the machine used to separate the fibers from the stem were also investigated and it was observed that the operating parameters of the machine did not adversely affect the natural properties of the fibers produced.

The purpose of this study is to examine the seam slippage in chenille fabric products which are widely used as upholstery fabrics and to research ways to decrease seam slippage. In this study, the theoretical analysis of the seam slippage mechanism has been performed by the literature analysis and the results of experimental studies which were obtained in Part I. In this analysis, seam slippage is examined as the sum of two factors: the deformation of sewing stitch and the slippage of the fabric yarns by sewing stitch chains. According to the theoretical analysis of the processes, it can be inferred that it is possible to decrease seam slippage by driving the energy of applied mechanical forces to other tasks. Based on the results, the ways to decrease seam slippage, which occur in sewn products, have been determined. Two of them are related to the selection of sewing yarn and sewing parameters based on...

For this purpose, polyester, polyester-cotton and cotton fabrics have been prepared followed by wet processing and drying. Drying is completed using conventional (convectional) and microwave methods. Fabric properties are determined both before and after drying and then compared. It is observed that the changes in group of properties for microwave drying are not much more than those in conventional drying method. In addition, some product properties get better by using microwave drying method. The results show that the drying method of textile products in electromagnetic field with extremely high changes is much more practicable.

So, the investigations about the chicken feather fibers reveal important properties of these fibers. Chicken feather fibers are obtained by mechanical cutting of the barbs which have fibrous structure, the structure branched from rachis and constitute the body of the feather. The rachis part of chicken feather constitutes approximately half of the weight of the feathers. So, it is necessary to examine the properties of the chicken feathers in order to gain their industrialization. This study is concerned with the mechanical and physical properties of the material that is taken as a by-product in the production of fibers from chicken feathers and constitutes the rachis part of the feathers.

Today, the presence of acoustic problems in transport vehicles such as airplanes, cars and train wagons has become one of the major problems of modern life. Many methods and materials have been developed to provide acoustic comfort in indoor spaces. One of them is the development and application of sound-absorbing materials. Nonwoven webs, which are considered to be the most ideal materials for sound insulation, have micron-sized pores as well as large surface areas. Among these materials, materials with double-layered porosity have greater effect. In recent years, researchers are increasingly turning to the development of sound-absorbing materials from production waste and natural materials that are easily decomposed in the environment. In this study, the sound-absorbing properties of nonwoven webs produced from chicken feather fibers, a by-product in chicken p...

The purpose of this study is to reduce the seam slippage in upholstery chenille fabrics, which are widely used in furniture production. This is the preliminary study, in which the effects of sewing direction and the number of interlaced chenille yarns over warp yarns on seam slippage were investigated for the first time. Aside from the effects of fiber content, sewing stitch step, weft densities of fabrics, sewing direction according to the weft and warp and the number of interlaced chenille yarns over warp yarns on seam slippage were studied with the use of multifactor experiment. On the basis of these experiments, effects and impact factors of the aforementioned parameters on seam slippage were shown with the use of mathematical models.
