Silk, being the “queen of textiles”, passes through various procedures to ensure its quality. Pre-treatment is the process of soaking raw silk in a solution consisting of soap, oil, and water. Its primary purpose is to smoothen and elasticize the raw silk to expedite throwing operations. This paper aimed to modify the soaking solution for raw silk being used at DMMMSU-Sericulture Research and Development Institute, to improve the quality of fabric produced. The study utilized an experimental research design, using raw silk from silkworm hybrid DMMMSU 406. Pre-treatment was done using three types of edible oils such as castor oil, corn oil, and coconut oil as soaking agents with a material liquor ratio of 1:4:5:6. All the treatments passed the standards for breaking strength, dimensional change, and colorfastness. Results revealed that coconut oil had the lowest registered number of breaks, and the highest registered reflectance percentage. The same treatment also performed better in terms of cleanness, evenness, and neatness test.
