In the world of textiles, where comfort meets durability, a recent study has shed light on how washing can significantly alter the properties of knitted fabrics, with implications for manufacturers and consumers alike. The research, led by Koviljka A. Asanovic from the Faculty of Technology and Metallurgy at the University of Belgrade, Serbia, and published in the Journal of Engineered Fibers and Fabrics (which translates to the Journal of Engineered Fibers and Fabrics in English), delves into the changes in dimensional, mechanical, and comfort properties of cotton and wool double-weft knitted fabrics after washing.
The study focused on two types of knit structures: 1×1 rib and Milano rib, and examined how yarn composition, knit structure, and washing conditions influence fabric performance. Asanovic and her team found that cotton fabrics exhibited greater dimensional changes after washing compared to wool fabrics. “Cotton fabrics, particularly those with a 1×1 rib structure, experienced notable reductions in bursting strength, compressibility, and air permeability,” Asanovic noted. This is a crucial finding for manufacturers, as it highlights the importance of selecting the right yarn and knit structure to enhance the dimensional stability and functional performance of knitted products.
On the other hand, wool fabrics, especially those with a 1×1 rib structure, showed improved mechanical properties after washing. This could be attributed to the coarser yarns and denser knit structures observed in wool fabrics. The study also revealed that comfort-related properties declined after washing, with cotton fabrics experiencing more significant deterioration. This is likely due to their increased sensitivity to the stresses of the washing process.
The findings provide valuable guidance for the textile industry, particularly in the energy sector where textiles are used in various applications such as insulation and filtration. Understanding how different fabrics respond to washing can help manufacturers develop more durable and efficient products. Asanovic’s research underscores the need for careful consideration of yarn composition and knit structure to optimize the performance of knitted fabrics.
As the industry continues to evolve, this research could shape future developments in textile technology. By understanding the impact of washing on fabric properties, manufacturers can innovate and create products that are not only comfortable and durable but also energy-efficient. The study serves as a reminder that even the most mundane processes, like washing, can have a profound impact on the performance of textiles, and that there is always room for improvement and innovation in the field.
