    Chenille yarn has an increasing share of use in the upholstery fabric sector recently. To have an important place in chenille yarn production in the world, it has become necessary for manufacturers to improve the quality, durability, and performance of their products and to carry out innovative studies in this field. Increasing the abrasion resistance of the yarns that form the basis of upholstery fabrics will significantly affect the service life performance. In this study, two raw materials selected with different production parameters were examined. These raw materials are determined as viscose and polyester, which are mostly used for chenille yarn in the production facility. The parameters covered in this study are determined and evaluated as the fixed/unfixed state of the yarn, the state of having different twist values, and the presence or absence of melted yarn added to ensure better adhesion of the pile and binder yarn with each other. In this direction, to test the abrasion resistance of the yarns produced from 6 polyester raw materials and 6 viscose raw materials with different properties, they are woven into fabrics by weaving on a 65-density jacquard loom. Each fabricated sample is realized by Martindale test. This test is realized to see the result of friction force and impact effect on the fabric surface. Also, it is aimed to determine the resistance of the samples against pilling and surface change. Based on the results, different parameters affecting the abrasion resistance of upholstery fabrics obtained from chenille yarn were interpreted and it was aimed to be a pioneering study in this field.

    Mechanical Drive Random Short Pattern Machine Prototype

    One of the important producers of the industrial industry in our country is the textile sector. The importance of the textile industry for our country is growing day by day with increasing production and employment. In order to keep up with this growth, manufacturers need to go beyond their existing systems, show their differences and make the right innovations in their production. Considering these values, changes to be made in the yarn structure or dyeing process come to the fore. In this study, the dyeing process is discussed. Weaving and home textiles, which are an important part of the textile industry, have a wide market. There are different dyeing systems that have an important market for the products made in these areas. Spaced and smart painting, which are among these painting systems, do not meet the needs in the desired direction. A new machine design is needed to provide the desired features. In the study conducted in this direction; A commercially unavailable machine has been implemented, designed and manufactured to generate random short patterns with mechanical drive. In project scope; First of all , the paint stand to be integrated into the system was designed . Different yarn lifters and godet systems have been designed. Paint container, drive system and electronic panel are also mounted on the system. In addition, new software has been developed within the scope of the project to provide automatic control of the system. Studies were carried out with PLC and Arduino electronic circuit board. In the first stage, motor driver circuits were designed with PLC and Arduino. Then, with the software loaded on the PLC and Arduino processor board, the frequency values to be given to the inverter were started by changing the threshold ranges we wanted. Lifters and painting cylinders are connected to each other so that the same sequence is not repeated. Thus, in this study carried out in line with the needs, both a new machine and a new textile product with different dye patterns emerged.
