Natural Modified Starch and Synthetic Sizes in Function of Characteristics of Sized Yarn
Journal Title: Fibres and Textiles in Eastern Europe - Year 2016, Vol 24, Issue 1
Abstract
The aim of this study was to investigate the changes in properties of yarn made by sizing with synthetic and natural modified corn starch. Different procedures for obtaining modified natural (corn) starch and various combinations of natural and synthetic sizes were used to explore the differences in the properties of sized yarn. The sizing process was carried out under with constant conditions in a newly developed laboratory sizing machine on twisted cotton yarns of 20×2 tex and 30×2 tex. According to the results obtained, yarn sized with synthetic sizes has substantially better properties than those which are naturally sized with modified starch. However, sometimes these differences are not significant or they do not exist at all. Twisted yarn is not always necessary in sizing in order to increased its strength but rather to protect the surface from wear and refine projecting fibers; in this case natural modified starch from corn can meet the requirements. The significance of this research is the application of natural sizes, improvement of the sizing process with natural modified sizes using new achievements in the development of the sizing process, and thus creating a positive environmental and economic impact.
