The machines for Garneting, washing, Lap formation sealing, autoclave were sourced from small scale manufacturers Assembly line was created for effective manufacturing Packaging was done with Instruction sheets Instruction sheet for Belt less napkins The unit with machines could be set up in a room in any village or sub urban area Total cost of machines was about 100, 000 Rupees (500 BHD) Workshops were conducted for local women to train Instruction sheet for them for manufacturing, Packaging and selling Belted napkins
Distribution networks were created 03/01/2020 RUW CONFERENCE ON WOMEN AND SOCIETY 19 Conclusion Low cost sanitary napkins can be developed using alternate materials like cotton knitwear waste and Bagasse pulp as the absorbent web. Quality of the sanitary napkins thus made are comparable in quality to branded sanitary napkins in terms of various physical and hygiene parameters. This will enable the women from the lower economic strata to use disposable sanitary napkins, thus ensuring improved status of menstrual hygiene. The assembly line can easily be established in rural, semi urban areas and trainers trained to implement it as an entrepreneurial venture. This fulfils the needs of women and society.
