Background: The practice of rearing eri silkworm is extensively practice in Bishnupur district of Manipur. The current study aimed to access the input factors for production as well as major constraints faced by the respondents during its production and marketing. Methods: The present research investigation was carried out during the agricultural year 2020-21 with a total of 120 respondents were selected by following a multi-stage simple random quota sampling technique. Result: Study reveals that the majority of the female respondents were actively doing Eri-rearing; the total cost of cultivation of Eri-rearing was ₹ 8,530 per 100 dfls with 90 kgs cocoon produce with gross and net returns viz; ₹ 13,500 and ₹ 4,970 respectively on semi-medium farm category.

“…11 Modern processing techniques like ultrasonic, microwave and supercritical fluid carbon dioxide (CO 2 ) have also been explored to remove sericin from silk. 12,13 The plant origin bio-surfactants like Sapindus mukorosssi, Sapindus laurifolia, Acacia concinna, and Acacia auriculiformis due to their amphiphilic nature, have been widely studied in various types of applications. The soapnut tree is native to China and southern India but has now spread to nearly every country on the planet.…”

“…Unlike synthetic chemicals, soapnut saponin is a natural substance with no environmental risks. 15,16 Sapindus mukorossi commonly known as Reetha, a plant-based non-ionic bio-surfactant obtained from the fruit's pericarp, is used as a substitute for synthetic soap and detergent in India. The pericarp of the fruit of Reetha or soapnut containing saponin (6-10 wt%) has surfactant properties.…”

The present investigation aims to develop a method for degumming Eri silk using Sapindus (soapnut) extract and optimise it using response surface methodology (RSM). The initial experiment was conducted with 10 g/L Sapindus extract for 60 min at a boil, and the initial experiments indicated effective degumming. Further degumming experiments were conducted using RSM to optimise the process parameters, with weight loss being the primary response. The results revealed an optimised recipe for degumming was 9 g/L Sapindus extract at 92°C for 30 min, and the desirability value for this optimised recipe is 0.376. Eri silk that has been alkali‐degummed loses more weight than silk degummed with Sapindus extract and soap. Comparatively speaking, degumming with Sapindus extract has a lesser impact on tensile strength than degumming with alkaline and soap. The whiteness, yellowness, brightness, and absorbency values between Sapindus extract and conventional degumming do not significantly differ. Compared with soap and Sapindus extract degumming, alkaline degummed fabric exhibits higher dye uptake. After being degummed with soap and Sapindus extract instead of alkaline, the fabric felt softer. Overall, the results show that both degumming with Sapindus extract and traditional methods are equally effective.
