“…On the contrary, the absorptive capacity of the developed sample (DS-02, DS-04, DS-05 and DS-06) is boosted by the incorporation of absorbent fibres such as cotton and viscose together with CMC and sodium alginate inside the core layer as an alginate containing large amounts of hydroxyl group, COOH groups and hydrophilic carboxyl group of CMC which really contributes to the absorption of a lot of water (Tang et al 2014). Although the commercial pad sample (CS-01) has a slightly higher absorptive capacity compared to newly developed samples (DS-01 to DS-06), but by using absorptive textile fibre such as viscose and eco-friendly available chemicals such as sodium alginate, CMC can eliminate environmental problems and offer not only safe environmental disposal but also body hygiene and comfort by minimizing irritation and other health issues on prolonged contact to human body (Berkley 1987;Yadav et al 2016).…”

“…The health-conscious female is nowadays following a multitude of products including sanitary pads, tampons, panty liners and menstrual cloth pad with three principal layers: the top sheet, the absorbing core of absorbing materials and the leaking barrier sheet (Yadav et al 2016). Traditionally, the absorbent core has been developed from wood pulp but continuous efforts are being made to substitute it with air-laid wood pulp and SAP to increase its efficiency of absorption (Zohuriaan-Mehr et al 2010).…”

“…The loosely cross-linked structure along with extended polymer chains with water enables them to attain additional absorbency. Despite this specific benefit, the commercial sample has some constraints, since SAP are petroleum-based polymers that do not easily deteriorate in earth (Yadav et al 2016). SAP also causes some adverse effects on the health of the user as long-term exposure causes severe reactions such as skin infections and even toxic shock syndrome (Berkley 1987).…”

Background Managing menstrual hygiene in the least developed countries represents a significant obstacle for women and girls. Commonly dirty stuffs are used to control the menstrual cycle which causes many diseases, while disposable hygiene-absorbent material during menstruation is an essential requirement. Most local commercial sanitary napkins offer high absorptiveness and flexibility; however, most of them, due to the use of synthetic superabsorbent polymer (SAP) within the core layer, are not biodegradable and harmful to human skin. This research aims to create a sanitized and biodegradable pad in order to replace SAP with environmentally sound biopolymer that give rural poor women competent performance and characteristics. Result For the construction of the model, some of the current sanitary pads from the local market are examined. Six models are designed using various biopolymers such as cotton, viscose, wood pulp, sodium alginate and carboxy methyl cellulose (CMC) in different proportions as the core absorbent layer to boost requirements such as absorption, fluid retention strength, coziness and cost reduction. The sanitized pads have gone through various investigations such as antimicrobial activity, wicking ability and water retention capacity to standardize vital features and value. The experimental results show the use of sodium alginate and CMC is a possible replacement for SAP as the best comparable result is observed in template consuming sodium alginate, CMC and cellulosic fibre. Non-woven fabric treated with neem extract forming the outer layer of sanitary napkin serving with antimicrobial activity of more than 90% against both gram-positive and gram-negative bacteria. Conclusion Outcomes recommend significant advancement and cost-effectiveness of the newly designed archetype. Sanitary napkins without SAP can be a safe disposal solution and can therefore have a sustainable environmental impact.

“…Furthermore, the easy processing for various shapes and the structural stability of nanofibers compared to powders are useful for a wide range of applications. Thus, the fabrication of superabsorbent nanofibers (SANs) has been widely attempted because of the advantages that nanofibers offer, such as a high surface area and a porous structure . However, most previous studies produced SANs by simply adding nanofibers to SAP substrates or by adding SAP particles to polymer nanofiber structures that requires an additional process.…”

Superabsorbent polymers (SAPs) have been widely studied and used in various industries. In this study, SAPs based on sodium polyacrylate (NaPAA) and poly(vinyl alcohol) were successfully prepared in the form of nanofibers using the electrospinning technique. The heat‐treated superabsorbent nanofibers (SANs) with 7 wt% of NaPAA and containing both crystal structures and crosslinks presented the best absorption performance, with up to 3.9 times and 134% increase in the absorption area and swelling ratio, respectively. Furthermore, the crystal structure and crosslinking of the SANs enabled them to maintain their fiber network during water absorption and recovery. The absorption rate of SANs having both crystal structures and crosslinks was slightly lower than that of nanofibers with only crystal structures, but it was still higher than that of SAPs because of the highly porous nature of the nanowebs. The easy processing and structural stability of SANs are expected to be useful in a wide range of applications. © 2019 Society of Chemical Industry

Super absorbent polymer based on methyl methacrylate (MMA), methacrylic acid (MAA) has been prepared during the present work for coating the top layer of feminine sanitary napkins. Synthesized polymers were coated on the needly punched cotton and adjusted as the top layer of the sanitary napkins, which has been prepared. The samples were evaluated by means of absorbency capacity, rewet back, strike through, and pH by the comparative study with commercially available sanitary napkin. The most suitable ratio of monomers (60 g MMA, and 40 g MAA) for synthesizing polymer was suggested. Absorbency capacity of the said ratio is competing with commercial sample with 63.68 g absorbent capacity. Specially, pH of prepared polymers suggested the acidic value and those are more preferable for maintaining the acidic pH of vagina at the menstrual time. Present work suggests the polymer, which can be utilize for coating the feminine napkin by the comparative result suggested by absorbency capacity, rewet back, strike through, and pH.
