Vanya Silk Reeling
Recently Completed Project
Study on evaluation of cocoon stifling process on cocoon storage, reeling performance and quality of muga raw silk
S.N. Mishra, Naveen Padaki, Aswatha Reddy & D. Ravi Kumar
Optimum muga cocoon stifling and storage achieved. The standardized cocoon drying procedure will result in uniform cooking of cocoons and hence better reeling performance and raw silk quality. Stakeholders can use this technology and achieve significantly better results. Technology is being propogated by installing more number of driers in the field.
Modification of eri spinning preparatory machines for productivity and quality
Aswatha Reddy, K.P.Shivakumar & Subhas V. Naik
The design of opening machine required for eri cocoon opening cum lap forming machine has been conceived. Fabrication of the eri cocoon opening cum lap forming machine has been completed. This machine would help in improvement in productivity and quality of eri spun yarn significantly.
Studies on silk carpets: Influence of structure on carpet properties
Kiran B. Malali, Naveen V. Padaki, Jagannath Sardar & Subhas V. Naik (CSTRI, Bangalore); Sanat Pal & K. K. Goswami (IICT, Bhadoi)
Mulberry, vanya and eri spun silk yarns were procured through NHDC, dyed with acid colours in different colour shades and carpet samples using three different hand knot structures were prepared. These samples were tested for various carpet parameters at IICT, Bhadohi and recommendations have been made on the suitability of type of knot structure for particular applications.
Industry showed positive response to carpets produced from mulberry and vanya spun silks, particularly eri spun silk. The developed carpet samples will be displayed in important silk carpet clusters to popularize the use of spun silk yarn. The outcome will help in product development and diversification (for domestic and export markets).
Development of suitable cooking technology and characterization of raily cocoon
Uday C. Javali, Kiran B. Malali, Naveen V. Padaki & Subhas V. Naik
Cooking process of raily tasar cocoons for both dry and wet reeling has been optimised. Reeling parameters of the same have been standardised. Vis-à-vis silk yarn characteristics. Reeling performance of the improved cooking technology is significantly better than the conventional cooking method.
This cooking technology will help in uniform cooking of cocoon layers, requires lesser cooking time, improves reelability and silk recovery and reduced silk waste (deflossing and reeling) and suitable for wet reeling process (sunken system). The technology will help to consume raily cocoons for reeling, instead of spinning which is being practiced presently.
