The "alkali cooking" procedure plays a crucial role in the production of medical gauze swabs. It serves the purpose of eliminating the slurry, grease, and wax present in the grey cloth, and its effectiveness directly impacts the quality of the final product. Due to the substantial amount of pollutants generated during this process, it is vital to give special attention and care to this task.
To minimize the production of harmful substances during the manufacturing of medical gauze swabs, a range of procedures are generally undertaken. After removing grease, wax, and impurities from the gauze and rags in a hot cylinder, the materials undergo gas steaming, washing, and bleaching. Unfortunately, pollutants from earlier stages are sometimes carried over to later phases. To ensure that the finished gauze complies with quality requirements and hygiene standards, additional clean water is required for washing.
The medical gauze swab undergoes rigorous testing before it is released from the factory. It possesses a soft and smooth texture, excellent water absorption capacity, evenly distributed fibers, and a pure white color. Furthermore, it is odorless and free from any acidic or alkaline substances. To ensure its quality, only high-quality, loose-woven pure cotton gauze fabric is selected. This fabric is then subjected to a meticulous process of chlorine-oxygen double bleaching, which not only removes impurities but also degreases the cloth. Subsequently, the degreased gauze fabric is mechanically cut into strips and further shaped into medical gauze swabs of various sizes, based on the specific requirements.
