DEVELOPMENT OF BIO-DEGRADABLE BABY DIAPERS

Abstract

A diaper or nappy is an absorbent garment worn by babies until they are potty trained. The disposable baby diapers are multi-layer structures consisting of layers of different materials. The disposable diapers are comprised of a polypropylene top cover stock, an absorbent layer, a polyethylene back sheet and elastic bands. The top polypropylene sheet is a Hydrophilic non-woven sheet which permits the urine to pass through it and reaches the absorbent core. The middle portion is a super absorbent polymer which helps to hold the urine away from the skin and faecal enzymes. The diapers back/bottom-most sheet is hydrophobic non-woven films made up of polypropylene fibers. In our project an attempt was made to produce a bio degradable baby diaper by eliminating the polypropylene non-woven with specially finished bio degradable viscose non-woven so that the pollution will be reduced and expecting the product will fulfil the functional properties of the diaper.
