EXAMINING THE RESISTANCE OF THE FABRICS KNITTED FROM METALIZED YARNS PRODUCED BY USING LAMINATION TECHNIQUE AGAINST TO TEXTILE FINISHING PROCESSES

The pre-finishing, finishing, and dyeing processes applied to the fabrics are carried out at high temperatures, in acidic or alkaline environments. Conventional metalized yarns which are produced by metalized yarn companies cannot resist these conditions that change due to raw material type. Metalized parts exfoliate when exposed to these conditions, and shiny appearance disappears completely. Therefore, in order to be a solution for this problem for the products that the use of metalized yarn is required, companies produce fabrics by using metalized yarns that were colored in bobbin form and choose proper application conditions for metalized yarns. However, because this solution increases production time and workmanship, the production costs and the product’s sale price increase correspondingly. The use of metalized yarns with untreated fiber is more advantageous than the method mentioned above for companies in terms of both cost and ease of production process. For this purpose, in this study, the resistance of metalized yarns that were produced by using lamination technique was tested against the chemicals which metalized yarns can be exposed during textile finishing processes, and the appearances of the fabrics were evaluated. Because metalized yarns are commonly used in the production of cotton and polyester fabrics, finishing processes that are applied to cotton and polyester fabrics were applied to metalized fabrics in a textile finishing laboratory. Then post-processing appearances of fabrics were evaluated subjectively. © 2020. Journal of Textiles and Engineer. All Rights Reserved.
