Comparison of Several Cotton Yarn Properties before and after Conditioning

This article summarizes the effect of yarn conditioning on several yarn properties like moisture content, tenacity, elongation at break and yarn hairiness. At the early stages of fibre to yarn manufacturing, the range of moisture content in the cotton fibre lies around the standard level but after yarn manufacturing which becomes lowered, which creates several negative impacts on different yarn properties. To avoid this incident, presence of exact amount of moisture in the fibres is ensured through yarn conditioning process. During this research, yarn made from different fibre lots were tested before and after conditioning to analyze how conditioning puts significant impact on moisture content, tenacity, elongation at break and hairiness of yarn. The result showed around 5% increase in moisture content, around 4 to 6% decrease in hairiness, 12 to 13% increase in elongation at break, and a significant change in yarn tenacity. Besides these, this article also provides some explanations behind each impact.
