1054 Improvements to Eco-Friendly Sanitary Napkins made from Natural Fibres: Development and Characterization effort to meet the demands of sustainability and eco-friendliness on a global scale [2-4]. The revival of interest in products made from renewable resources is a result of ecological concerns. Natural fibres, agro-waste fibers and biodegradable polymers might be thought of as an environmentally safe option because of this [5]. All natural fibres and agro-waste fibers are low density, less harmful to technology used for processing them, economically viable, and biodegradable [6]. A unique aspect of female development is the use of sanitary napkins during the menstrual cycle, when a woman's body is most vulnerable and she needs to take the necessary safety steps to protect herself. A wear study conducted to assess the comfort of sanitary napkins revealed that a highly humid microclimate developed in the area between the napkin and the skin, which led to subjective pain. Inconvenience related to sultriness was reported by more than 60% of the individuals [7]. This discomfort is brought on by the increase in temperature inside the napkins, and adults who use diapers have also reported feeling it [8]. Due to the fact that vaginal bacteria like Candida albicans thrive in warm, moist environments and cause infections, women become more vulnerable to vulvo-vaginal infections as a result. A free flow of water vapor could lessen the pain caused by napkins [9]. The vulva region, which is made up of epithelial tissues, surrounds the vaginal opening. This tissue's structure, occlusion, moisture, and susceptibility to friction set it apart from other bodily parts. The vulva, like other epithelial tissues, defends the vagina from hazardous bacteria through the use of defense cells. However, inadequate ventilation, heated settings, and minor wounds brought on by friction between clothing and skin encourage the growth of microorganisms. This worsens if the user wears underwear, pantyliners, or sanitary napkins made of synthetic materials, which raise the temperature and pH of the vulva region and lead to a variety of skin infections that manifest as itchiness, soreness, redness, and swelling in the vaginal area [10]. The polypropylene (PP) spunbond nonwoven is used as the outer cover material for the majority of sanitary napkins, which are the absorbent pads worn externally by women during menstruation to absorb the menstrual flow [11]. This outer cover stock is better suited for sanitary napkins because it is in close contact with the skin of the vulva region [12]. This article discusses the various styles of sanitary napkins that have been produced from a variety of raw materials that have been improved and developed through earlier research.
2. Materials and Methods 2.1 Methods for Preparation of Sanitary Napkins from Natural Fibres 2.1.1 Assembly of sanitary napkins with prepared absorbent core layer Absorbent core
- 25 cm in length and 7.5 cm in width - 25 cm in length and 7.5 cm in width
Leak proof polyethylene sheet
+ (2 * Thickness of prepared absorbent core) Cover stock polypropylene sheet
- length-27 cm and width-18 cm Polypropylene sheet was used to cover the absorbent core and leak-proof polyethylene sheet at the bottom. They are joined by a seal. The sanitary napkin is subsequently manufactured and sealed. 2.1.2 Top Layer The top layer is made entirely of spun bamboo, which is hypoallergenic, soft, and biodegradable, by nature. A non-woven fabric with a web-like structure is produced by the spun lacing process, offering a soft and smooth surface.
