In this paper thermal properties of spun silk yarn produced from mulberry, muga, tasar waste, red eri and white eri cocoons on worsted system of spinning mill and three varieties of plain fabric woven on power loom by using 2/60s Nm in warp , 2/60s Nm , 2/80s Nm and 2/120s Nm yarns in the weft in each variety of silk have been studied. The thermal properties of fabric have been tested according to international standard testing methods. Results of investigations of thermal properties of fabric have been presented as per the requirement of industry. Results have been compared among each variety of fabric. The results indicate that variety of silk, weft yarn count and interaction effect are significantly affecting the thermal properties of spun silk fabrics. Source

In the reeling process, proper disposal of the leftover pupae remain a subject of concern for the entrepreneur. Sometimes, if the wet pupae are not disposed in the same day from the reeling unit the reeler is subjected to the wrath of the neighborhood as the heap of the pupae dumped in reeling unit produces loathsome stink around due to decaying. Due to lack of proper disposal techniques, the issue remains to be weary for the entrepreneur. Caught unaware of the additional revenue and owing to cumbersome process in drying and storage of the pupae, the disposal goes awry. With the perspective of doing away with the problems associated with conventional pupae drying (open air sun drying), a proto type of Silkworm Pupae Solar Dehydrator (SPSD) was designed, fabricated and tested successfully. The loaded SPSD cabinet temperature, moisture and pupae drying rate were examined in both fair and murky climatic conditions. The cost-benefit analysis suggests that the revenue through SPSD dried pupae is about 11 times that of the conventional open-air sun-drying method. Moreover, the payback period on the investment to manufacture the SPSD is around 7 months. Because of simple design and bountiful advantages associated with SPSD, the proposed commercial application seems to be viable for silk reeling sector. Source

The Jovar stalks that are used as reeds are responsible for effective weaving of costly silk sarees on hand looms with and pure zari threads. The prime advantages of these reeds are that they do not harm the silk and zari threads while weaving and impart better luster. Various types of reed are used in textile manufacture such as expanding, flexible, gauze, leasing and ordinary, 'v' type, zigzag, warp ondule, weft ondule and bamboo reeds. The Jovar reeds were earlier used with the height of only 2 inches, as the shed formed by the weavers in handloom weaving was very small and they could insert the shuttle by hand without any problem. The bamboo reeds are also used for saree weaving in handloom. The metallic reeds are being used in the power loom industry effectively. Source

Peddahiagari Mohan, residing in thickly populated bylanes of weaving neighborhood in Dharmavaram, is a connoisseur in embroidery designs on silk saris. He has created altogether new concepts of designing out of his sheer passion for innovation. Unlike traditional designing methods, he draws the designs directly on a plain silk sari with the help of a pencil. His unrelenting hunt for new designs brings in best collection into his digital design gallery. Accolades shower as hundreds of women, especially from weaker section, received training under his expertise. He is highly content as he finds many of them either working for some societies or leading their own design studios. While many of the talents quite often go unnoticed, he has braved the setbacks and kept afloat. In a situation where the behavior of the customers is converging upon to look for something new, he finds solace in finding his efforts fall in place, in near future. Source

To expand use of silk in diversified products, new silk yarns with new characteristics have to be developed. Production of blend silk yarns during silk reeling process is one of the attempts in this regard. The mechanism and gadgets required for production of blend silk yarns have been developed and fixed to CSTRI multi-end reeling machine. The blend silk yarns using polyester, viscose, nylon and cotton yarns in the core were developed and silk yarns equivalent in denier to each of these yarns were also developed for comparison. From the yarn characteristics it is observed that uniformity of blend silk yarns is significantly better than the corresponding silk x silk yarns. Strength of corresponding silk x silk yarns has been found to be significantly better than silk x polyester, silk x viscose and silk x cotton cover yarns. It is also observed that, elongation of silk x viscose yarn is significantly better than that of silk x silk yarn, whereas elongation of silk x silk yarn is significantly better than that of silk x cotton yarns. Quality characteristics of blend silk yarns indicate that these silk yarns can be utilized for the manufacture of innerwear, dress materials and furnishings with distinct characteristics. Source
