AI Technical Summary
Existing oil-absorbing cleaning paper has problems such as mediocre oil absorption speed and amount, easy backflow, powder shedding, scratches, and poor user experience, especially when using natural fibers as the main raw material. In addition, the existing methods increase the operation steps and costs.
By combining nanocellulose and polyhydroxy fatty acid ester emulsion with Pickering emulsion method, and adding hemp pulp Lyocell fiber, filler particles are added into the pulp. The auxiliaries succinic acid and sodium hypophosphite are cross-linked with cellulose at high temperature to form a stable paper structure, which improves oil absorption and tensile strength.
It achieves high oil absorption capacity, stability and tensile strength of oil-absorbing cleaning paper, improves the user experience, enhances softness and breathability, and improves the safety and environmental friendliness of the product.
