Production Analysis of Disposable Diaper Pads
Disposable Diaper Pads are an important accessory used with baby diapers or adult care products. They absorb and lock in urine, preventing leaks and keeping the baby or adult dry. These pads are made from various materials, with the front side often made of absorbent and soft materials, while the back side is typically made of waterproof and impermeable materials. High-quality Diaper Pads are designed with four layers: the top layer, the absorbent layer, the waterproof layer, and the bottom layer. The waterproof layer is made of TPU (thermoplastic polyurethane) waterproof and breathable membrane. This design effectively balances absorbency, waterproofing, breathability, and comfort, ensuring the baby stays comfortable.
Below, we will detail the production method for disposable Diaper Pads.
Selection of Raw Materials The primary raw materials for disposable Diaper Pads include absorbent materials, surface materials, glue, and paper cores. Among these, absorbent materials are the main component, generally made from a composite of super absorbent polymer (SAP) and wood pulp fiber. The surface material, coated with a waterproof layer and breathable pores, is typically non-woven fabric or soft cotton. Glue is used to bond the absorbent materials and surface materials together.
Manufacturing Process The manufacturing process for disposable Diaper Pads typically includes the following steps:
Preparation of Raw Materials Prepare and cut the absorbent materials, surface materials, and paper cores into the appropriate sizes.
Preparation of Absorbent Material Mix the super absorbent polymer (SAP) with wood pulp fiber to create the absorbent material, then blend according to a specific ratio.
Making the Urine Pad Core Layer the absorbent material, surface material, and paper core in a specific sequence and method, then use a hot press machine to heat and press them into shape.
Surface Treatment Treat the surface of the urine pad, including applying a breathable waterproof layer and leaving breathable holes.
Packaging and Inspection Package the finished product and conduct inspections to ensure quality standards are met.
Product Inspection The inspection of disposable urine pad products includes the following aspects:
Appearance Check Inspect the appearance and dimensions of the Diaper Pads to ensure they are smooth and meet specifications.
Absorbency Test Test the absorbency by adding a certain amount of liquid to the urine pad and checking the absorption time and amount.
Leakage Test Test the pad's performance under conditions that simulate leakage to ensure it does not leak.
Breathability Test Test the breathability of the urine pad to ensure it meets the required standards.
