These are the most recognized form of cellulose sponges. They are versatile and used for general household cleaning tasks. Their absorbent nature makes them perfect for wiping surfaces, cleaning dishes, and mopping spills. The soft texture ensures that they do not scratch or damage delicate surfaces.

Cellulose cloths

These are thin, flexible sheets made from the same material as traditional sponges but in cloth form. They are ideal for dusting and polishing surfaces like glass, stainless steel, and wood. Depending on the task, the cellulose cloths can be used dry or damp, and are particularly effective for streak-free cleaning.

Scrubbing pads

Scrubbing pads are thicker and often coarser than traditional sponges. They are designed for tougher jobs, such as removing baked-on food from pots and pans or scrubbing bathroom tiles. While they are abrasive, they are still safe for most surfaces without causing scratches.

How is a cellulose sponge made?

The manufacturing process of cellulose sponges is fascinating and environmentally conscious. It utilizes natural materials and advanced technology to create a versatile cleaning tool.

Step 1: Raw material preparation

The primary material used in cellulose sponges is wood pulp, which is rich in cellulose fibers. This pulp often comes from softwood trees like pine or spruce. To prepare the pulp for sponge production, it is mixed with other natural fibers, such as cotton or hemp, to enhance the sponge’s absorbency and durability.

Step 2: Fiber processing

The mixed fibers are then processed to remove any impurities and to ensure that the pulp is of uniform consistency. This involves cooking the fibers in a solution of water and chemicals, typically sodium hydroxide, which helps break down the plant material and turn it into a soft, gelatinous mixture.

Step 3: Molding

Once the cellulose mixture is ready, it is poured into large molds. These molds can be of various shapes and sizes, depending on the desired form of the final product, whether it is traditional rectangular sponges, pads, or custom shapes.

Step 4: Adding porosity

To transform the dense cellulose mixture into a sponge-like material, a blowing agent is added during the molding process. The most commonly used blowing agent is sodium sulfate, which helps create the open-cell structure typical of sponges. As the mixture heats up, the blowing agent generates tiny air bubbles throughout the cellulose matrix, forming pores that can absorb and hold water.

Step 5: Curing and washing

After molding, the sponge material undergoes a curing process where it is heated in an oven. This step solidifies the structure and ensures the sponge maintains its shape and texture. Following curing, the sponges are thoroughly washed to remove any chemical residues, primarily the sodium hydroxide and sodium sulfate used earlier in the process.

Step 6: Drying and cutting

The final steps involve drying the sponges to remove all excess moisture, ensuring they are completely dry before packaging. Once dry, the large blocks of sponge material are cut into the final shapes and sizes, from large sheets for industrial use to smaller, household sponges and everything in between.

Technology and innovations

Innovative technologies are employed throughout the production process to ensure efficiency and quality. Automated cutting machines provide precise dimensions, and computer-controlled mixing and curing systems ensure consistent results in every batch. Additionally, modern environmental technologies treat and recycle water and chemicals used during manufacturing, minimizing waste and environmental impact.
