Silk has long been used to produce luxurious textiles of the finest quality. However, a major issue of the silk industry is that a huge amount of waste is generated from preparatory processes to spinning. Only 45–48% of silk can be found based on weight which is shallow silk recovery during the reeling process and the huge quantum of the silk remains waste in the form of floss. The silk waste after the pierced cocoon cooking process, reeling process, half-reeled cocoon, unreelable cocoons, waste produced in the reeling, and non-twisted silk waste produced at the time of the re-reeling process can be reduced by recycling as it is a significant concept of modern waste management and utilizing it in the textile sector. To make use of silk waste for better applications and to increase its commercial value, an effort was made to produce a product from blended yarn using Muga silk waste and Tasar silk waste. And this will also help in the growth of the country’s economy. This study aims to deal with cleaner production by recycling waste silk fibers for products. In this study, blended yarns were prepared using Muga silk waste and Tasar silk waste in three different ratios: 30:70, 50:50, and 70:30. Fabrics were constructed in plain weave using the prepared blended yarn and tested for different properties, which shows that the fabrics were suitable for product development. It was found that the 50:50 blended fabric was the best among the three ratios.

摘要

Silk has long been used to produce luxurious textiles of the finest quality. However, a major issue of the silk industry is that a huge amount of waste is generated from preparatory processes to spinning. Only 45–48% of silk can be found based on weight which is shallow silk recovery during the reeling process and the huge quantum of the silk remains waste in the form of floss. The silk waste after the pierced cocoon cooking process, reeling process, half-reeled cocoon, unreelable cocoons, waste produced in the reeling, and non-twisted silk waste produced at the time of the re-reeling process can be reduced by recycling as it is a significant concept of modern waste management and utilizing it in the textile sector. To make use of silk waste for better applications and to increase its commercial value, an effort was made to produce a product from blended yarn using Muga silk waste and Tasar silk waste. And this will also help in the growth of the country’s economy. This study aims to deal with cleaner production by recycling waste silk fibers for products. In this study, blended yarns were prepared using Muga silk waste and Tasar silk waste in three different ratios: 30:70, 50:50, and 70:30. Fabrics were constructed in plain weave using the prepared blended yarn and tested for different properties, which shows that the fabrics were suitable for product development. It was found that the 50:50 blended fabric was the best among the three ratios.
