The development and application of new types of fibres and their wider application influence the continuous invention of a more economical starching process, as one of the most expensive stages in the technological process of woven fabric production. For example, aramid fibres are increasingly used in clothing with effective protection from mechanical, thermal and abrasion exposure. Simultaneously, comfort and regulation of metabolic heat are extremely important, and this is achieved by using cotton woven fabrics. For such a woven fabrics to satisfy the protective properties and the possibility of all-day wear, fibre is needed, and thus a yarn, that will enable the efficient production of fine, light and comfortable protective woven fabrics. This paper investigates the influence of starching on the mechanical properties of aramid yarns and their comparison to cotton yarns of the same fineness. This will lead to knowledge about the efficiency and necessity of aramid yarn starching. The tests were carried out on an industrial and laboratory starching machine. According to the obtained results, the necessity and the improvement of the physical-mechanical properties of cotton and aramid yarns can be determined, both by industrial and laboratory starching. Finer yarn starched by the laboratory starching process achieves greater efficiency in the yarn's strength and resistance to wear, which indicates the need for starching aramid yarns, especially fineness 16.6 × 2 tex, but also finer ones.
新型纤维的开发与应用及其更广泛的应用，影响着更经济的上浆工艺的不断发明，因为上浆是机织织物生产工艺流程中最昂贵的阶段之一。例如，芳纶纤维越来越多地用于具有有效抵御机械、热和磨损作用的服装中。同时，舒适性和代谢热调节极为重要，而这可通过使用棉机织物来实现。为使这种机织物满足防护性能和整日穿着的可能性，需要能高效生产出细、轻且舒适的防护机织物的纤维，进而需要纱线。本文研究了上浆对芳纶纱线机械性能的影响，并将其与相同细度的棉纱线进行比较。这将得出有关芳纶纱线上浆效率和必要性的认识。试验在工业和实验室上浆机上进行。根据所得结果，通过工业和实验室上浆均可确定棉和芳纶纱线物理机械性能的必要性及改善情况。经实验室上浆工艺上浆的较细纱线在纱线强度和耐磨性方面实现了更高的效率，这表明需要对芳纶纱线进行上浆，尤其是细度为16.6×2特克斯的纱线，以及更细的纱线。
