ABSTRACT

Today, microcapsule application to textile materials is a widely used for the production of functional textile products. Microcapsule application methods used in practice have some significant disadvantages. There is a need for innovative methods to eliminate or minimize these disadvantages. From this point of view, in this study, it was aimed to develop an alternative method based on integrating microcapsule particles into the open staple fiber bundle before the spun yarn formation on the classical ring spinning. It was thought that this application method could allow the incorporating microcapsules not only the fibers on the yarn surface but also to the surface of the fibers in the yarn structure. Microcapsule doped and undoped ring spun yarns having Ne 16 yarn count with knitted twist were produced from viscose fibers. Obtained ring spun yarns were subjected to winding and knitting processes in order to analyze the effect of friction on the microcapsule presence. SEM images taken from yarn and fabric samples were examined. Additionally, yarn properties were analyzed. In order to evaluate the performance of the alternative method, microcapsule dispersion at the same concentration was applied to the knitted fabrics using pad-dry-cure method, which was widely used for production of the functional textile products. Two types of microcapsule applied knitted fabric samples were washed several times and presence of microcapsules was evaluated with SEM images. Furthermore, thermal properties of the both types of application methods were compared by examining T-history curves. The findings indicated that the alternative method offers comparable yarn and thermal properties with environmentally friendly application as well as washable and durable to the friction effects occurring in industrial processes.

摘要

如今，微胶囊应用于纺织材料已广泛用于生产功能性纺织产品。实践中使用的微胶囊应用方法有一些明显的缺点。需要创新方法来消除或最小化这些缺点。从这个角度来看，本研究旨在开发一种替代方法，该方法基于在经典环锭纺纱形成细纱之前将微胶囊颗粒整合到开纤短纤维束中。据认为，这种应用方法不仅可以将微胶囊掺入纱线表面上的纤维，还可以将微胶囊掺入纱线结构中的纤维表面。由粘胶纤维生产具有Ne 16纱支和针织捻度的微胶囊掺杂和未掺杂环锭纱。对获得的环锭纺纱进行卷绕和针织过程，以分析摩擦对微胶囊存在的影响。检查了取自纱线和织物样品的 SEM 图像。此外，还分析了纱线特性。为了评估替代方法的性能，使用轧干固化方法将相同浓度的微胶囊分散体应用于针织物，该方法广泛用于生产功能性纺织品。两种类型的应用微胶囊的针织物样品被洗涤数次，并用 SEM 图像评估微胶囊的存在。此外，通过检查 T 历史曲线比较了两种应用方法的热性能。
