A team of research scholars from the Indian Institute of Technology, Hyderabad has developed sanitary napkins which have a greater absorption capacity than commercially available ones. The most interesting property of these napkins is that they can be disposed safely thanks to their bio-dgradable nature.
The team, under the supervision of Professor Chandra Shekhar Sharma of the Chemical Engineering Department and his associates, Mani Pujitha Illa, Sheetal Yadav, have introduced the use of electrospun cellulose acetate nanofibers as a material for an absorbent core in the sanitary napkins which leads to better absorption. Not just that, the product is also safer and a lot more comfortable.
It's benefit is that it eliminates the use of harmful, non-biodegradable SAP (Super Absorbent Polymers) prevalent in commercially available sanitary napkins without compromising the performance. Instead, it's a better version because it comes with greater absorbency and comfort. Unlike commercially available napkins that use microfibre, nanofibre is smooth and has uniform roughness. These make the nanofibre samples more comfortable
The current sanitary napkins contain chemicals that are petroleum-based products which are harmful and do not degrade readily in landfills, definitely far from eco-friendly. Additionally, poor quality napkins have been known to cause toxic shock syndrome and ovarian cancer. Negligence about menstrual hygiene increases the vulnerability towards reproductive tract infections. Finally, we may have a safer alternate.
