The wet processing of regenerated cellulosic fabrics involves a complex interplay of chemical treatments, process control parameters, utility consumption, and associated costs. This review provides a comparative study of different regenerated cellulosic fabrics – such as viscose, lyocell, modal and Bamboo by evaluating the chemical recipes used, process control parameters employed, utility consumption patterns, and the cost per kg of fabric during the wet processing phase.

According to CPCB the status of sewage sludge treatment in India is currently inadequate, with most sludge generated being disposed of in dumpsites due to a lack of proper treatment facilities. Despite recent improvements in overall sewage treatment capacity; only a small percentage of generated sludge is actually treated, highlighting a significant gap in management practices across the country. Radiation Technology provides an excellent route to safely and effectively recycling and agronomically use of sewage sludge.

Commercial sanitary napkins typically consist of three to four distinct layers, each engineered to perform a specific function. Most branded products incorporate a permeable top sheet composed of polypropylene to facilitate fluid transfer, an absorbent core consisting of superabsorbent polymers (SAPs) or cotton fibers for fluid retention, and an impermeable back sheet made of polyethylene to prevent leakage.
