DMMMSU Research and Extension Journal, 8, 82–92. https://doi.org/10.62960/dmmmsu.v8i.480119-2035https://doi.org/10.62960/dmmmsu.v8i.48https://lakasa.dmmmsu.edu.ph/handle/123456789/684Sericulture products such as woven linen and novelty items were already sold at the market at premium-priced commodities. However, it was not given emphasis and sustainable support. One of the problems identified is the availability of cocoon silk production machinery and equipment. Humans can defloss 2 to 3 kg or 900 to 1,600 pieces of cocoon in an hour. Therefore, cocoon delfossing is a tiresome laborious job. This contributes to the market's poor production of silk and novelty items. Hence, a cocoon deflossing machine with a higher deflossing capacity than a manual is needed. To address this concern, a mechanically aided cocoon deflossing machine was designed, fabricated, and evaluated. Performance evaluation of the machine shows that it lessens deflossing cost from USD 0.53 /kg manual deflossing to USD 0.47/kg. It has a capacity of 4.80 kg/hr and 2,374 pieces of cocoons per hour.enSericulture--Equipment and suppliesSilk industry--MachineryCocoon processingAgricultural machineryPostharvest systemsSericultureSericulture--MachinerySericultureSilkworms--RearingMulberryCocoon productionAgricultural productivityArticle
