Production of bulky silk is the need of the hour as the same is required for weft in the production of silk sarees. So far raw silk produced in charkha reeling device was used for the purpose. But due to non-availability of skilled labourers and improper working atmosphere in charkha reeling sector, alternative methods of production of bulky raw silk were thought off. In this context, introducing PVA yarn in the process of silk reeling has been developed by CSTRI by modifying the multiend reeling machine for the production of bulky void raw silk. The bivoltine cocoons along with Indian PVA yarn is used for the production of bulky silk. Using the Box and Behnken design of experiments the process variables viz., Number of cocoons, croissure length, reeling basin water temperature and reel speed have been standardized with 27 combinations of experiments. The study indicates that process variables significantly influence the reeling performance and quality of bulky void raw silk produced viz., reelability, non-broken filament length, single cocoon filament denier, raw silk percentage, average denier, cross section view of bulky void raw silk. Based on the response optimization in statistical analysis, it was observed that 20 bivoltine cocoons reeled per end along with Indian PVA yarn with 6 mm croissure length, 50�C basin temperature and reel speed of 100 m/min is ideal for the production of bulky void raw silk on modified CSTRI multiend reeling machine. The bulky void raw silk is quite useful as weft in the production of silk sarees with unique surface characteristics.
