The Secrets of Diaper Production Process

With the development of modern technology, diapers have become an indispensable part of the parenting process. So, how are these seemingly simple but powerful diapers produced? This article will take you to reveal the production process of diapers and understand the sophistication and technological content of each step.

1. Selection and preparation of raw materials

The production of diapers starts with the selection of raw materials. The main raw materials include super absorbent polymers (SAP), fluff pulp, non-woven fabrics, elastic materials and adhesives. All kinds of raw materials undergo strict quality inspections to ensure the safety and comfort of the final product.

Super absorbent polymer (SAP): This material has a strong ability to absorb water and is one of the core materials of diapers.

Fluff pulp: A chemically treated wood pulp used to increase water absorption and softness.

Non-woven fabric: Used for the inner and outer layers of diapers, it has soft, breathable and leak-proof properties.

2. Production of the absorbent core

The absorbent core is the core part of the diaper, consisting of super absorbent polymers and fluff pulp. The steps to make the absorbent core include:

Crushing of fluff pulp: crushing large pieces of fluff pulp into fine fibers.

Mixing and molding: mixing the crushed fluff pulp with superabsorbent polymer to form the absorbent core. This process requires the use of special mixing equipment to ensure that the two materials are evenly distributed.

Pressing and cutting: pressing the mixed material into sheets of fixed thickness and cutting into the required shape and size.

3. Processing of non-woven fabrics

The inner and outer layers of diapers are mainly made of non-woven fabrics. Non-woven fabrics are given soft, breathable and leak-proof properties through specific processing processes.

Inner layer of non-woven fabric: directly in contact with the baby's skin, it needs to be softened to ensure comfort.

Outer layer of non-woven fabric: usually waterproof material to prevent urine leakage.

4. Assembly and molding

In this step, the various parts of the diaper are assembled together to form the final product.

Combination of absorbent core and non-woven fabric: fix the absorbent core on the inner layer of non-woven fabric, and cover the outer layer of non-woven fabric on the absorbent core.

Adding elastic materials: Add elastic materials to the waist and leg areas to ensure the fit and leak-proofness of the diapers.

Leak-proof sides and Velcro: Add leak-proof sides on both sides of the diapers, and install Velcro or other fixings on the waist for easy wearing and taking off.

5. Quality inspection and packaging

Each diaper needs to undergo strict quality inspection before leaving the factory to ensure that it meets safety and functional standards.

Appearance inspection: Check the appearance of the diaper to ensure that there are no defects and stains.

Functional testing: Test key properties such as water absorption, breathability, and leak-proofness.

Packaging and storage: After passing the inspection, the diapers are neatly packaged and stored in a dry and clean warehouse waiting for shipment.

The production process of diapers is not just a simple assembly, but involves a combination of multiple high-tech materials and complex processes. Each step requires delicate operation and strict control to ensure the safety, comfort and functionality of the final product. Understanding these production processes has given us a deeper understanding of diapers, and we are more grateful to the workers and technicians who have silently contributed behind the scenes.
