Some of baby diaper pants factory use the most common material combinations include:
Cotton or microfiber inner layer
Provides softness, breathability and absorbency against the skin. Cotton and microfiber fabrics are very comfortable for babies.
Polyester or plastic outer layer
The outer layer serves as a moisture barrier and helps contain urine and stool leaks. Polyester or plastic laminates are durable and waterproof materials commonly used for the outer shell.
Elastic waistband
An elastic waistband made of spandex, latex or polyurethane elastic helps provide a snug and adjustable fit for maximum leak prevention. The elastic waist complements the absorbent inner layer and waterproof outer layer.
Adhesive tape closures
Adhesive tape tabs or strips are often used along with or instead of an elastic waistband to securely fasten the diaper pants. The adhesive tapes help achieve a customized, form-fitting closure.
Gel core or absorbent inserts
Some diaper pants include a gel core, absorbent inserts or absorbent pads to provide extra absorbency and prevent leakage from heavier wetness. Super absorbent polymers are often used in these inserts.
Reinforcements
Diaper pants may use reinforcements like double layers, elastic legs, stretch panels etc. at high-stress areas to improve durability, prevent damage and leakage. Reinforcements strengthen the critical functional areas of the diaper.
Breathable crotch
The crotch area is made of a lightweight, breathable and non-absorbent material like polyester to allow skin breathability without getting soaked. Some diaper pants use mesh fabrics for the crotch area.
Leg gathers or elastic legs
Leg gathers made of elastic or non-elastic fabrics are used to prevent leakage from the legs. Elastic legs provide a snugger, more adjustable fit around the legs.
These are some of the most popular material combinations and features used in baby diaper pants. Different brands and products may use different variants, but these tried-and-tested combinations work well for absorbency, containment, comfort, durability and adjustability.
