Investigating an Appropriate Temperature for Heat Setting in a Stenter Machine to Control the Stretch and Growth of a Cotton Spandex Woven Fabric

Abstract

The aim of this project is to support the cotton spandex woven industry by manufacturing a wide variety of stretched clothes where, some friendly performance like wearer comfort, super stretch, elasticity and recovery can be achieved powerfully. This project is a practical based project, which can help not only the textile learners but also the fabric developer in a massive way to manufacture cotton spandex fabric and also to control their properties strongly. The difficulties found during manufacturing cotton spandex woven fabric were enlisted them cordially and after that all of them were solved earnestly. Cotton spandex woven fabric cannot be manufactured without trial, all of which are strongly discussed in this project briefly. This project work is just not a paper work, but it is an achievement, which has been achieved by working strongly in the textile mills. It is to be mentioned that, “stretch or super stretch” is a welcoming property which can increase the comfort level of wearer, on the other hand there remains another paradoxical property named “growth” which has some de-welcoming properties on fabrics for which it is strongly needed to be controlled and all these things are carefully discussed in this project. Growth basically has an increasing relative property with the increment of stretch, but at a stage, this increased growth brings about some negative effect in fabric which creates some bad impression to wearer. Although, growth is proportional to its stretch but this growth should not be increased with the increment of stretch due to which, it is required to be controlled through some additional but necessary treatment like heat setting through stenter machine at fabric’s wet processing zone. What actually happened due to heat setting the cotton spandex woven fabric and what changes happened in its internal structure that is also seen in microscope and analysed the differences and discussed it here in this project work.
