Plain spunlace nonwoven fabric: How to accurately prevent cross infection in the surgical environment?

Plain spunlace nonwoven fabric is a nonwoven fabric. Its production process involves opening, combing, and laying the fiber raw materials, and then spraying the fiber net with high-pressure water flow to make the fibers entangled with each other to form a cloth. This process retains the original properties of the fiber, such as hygroscopicity, breathability, strength, etc., while giving the fabric new properties, such as good liquid barrier and particle filtration. The key to the excellent protective effect of plain spunlace nonwoven fabric in the surgical environment lies in the precise control and optimization of its fiber composition.

The fiber type of plain spunlace nonwoven fabric has a decisive influence on its performance. Common fiber raw materials include natural fibers (such as cotton and linen), synthetic fibers (such as polyester and polypropylene) and regenerated fibers (such as viscose fibers). In the surgical environment, in order to effectively block pollutants such as blood and body fluids, it is usually necessary to select synthetic fibers with excellent liquid barrier properties, such as polypropylene (PP) fibers. Polypropylene fiber not only has the characteristics of high strength, wear resistance and chemical corrosion resistance, but more importantly, it has low surface energy and is not easily wetted by liquids, so it can effectively prevent liquid penetration.

However, a single fiber type is often difficult to meet the needs of complex and changing surgical environments. Therefore, in the production process of plain spunlace non-woven fabrics, different types of fibers are mixed according to specific application requirements to optimize performance. For example, in order to increase the softness and breathability of the fabric, a certain proportion of natural fibers or recycled fibers can be mixed; in order to enhance the liquid barrier properties of the fabric, the proportion of synthetic fibers can be increased, or fibers with special surface treatments can be selected.

In addition to the selection of fiber types, the proportion and arrangement of fibers are also key factors affecting the performance of plain spunlace non-woven fabrics. In terms of fiber proportion, by precisely adjusting the proportion of different types of fibers, customized design of the overall performance of the fabric can be achieved. For example, in applications that require high liquid barrier properties, the proportion of synthetic fibers can be increased; in applications that require good breathability and comfort, the proportion of natural fibers or recycled fibers can be increased.

In terms of fiber arrangement, the production process of plain spunlace nonwovens allows for multi-level and multi-dimensional arrangement of fibers. By adjusting the fiber arrangement density, direction, and number of layers, the pore structure of the fabric can be precisely controlled, thereby affecting its air permeability and liquid barrier properties. For example, by increasing the fiber arrangement density and number of layers, the liquid barrier properties of the fabric can be significantly improved; by adjusting the fiber arrangement direction, the tensile strength and flexibility of the fabric can be optimized.

In surgical environments, plain spunlace nonwovens are widely used in surgical towels and dressing materials for their excellent liquid barrier properties and good comfort. As an important protective product during surgery, surgical towels need to be able to effectively prevent the spillage of pollutants such as blood and body fluids, while maintaining sufficient air permeability and softness to ensure the convenience of medical staff and the comfort of patients. Plain spunlace nonwovens achieve effective barrier to pollutants such as blood and body fluids by precisely controlling the type, proportion, and arrangement of fibers, while maintaining good air permeability and softness, meeting the high performance requirements of surgical towels.

The dressing material also needs to have good liquid barrier properties and air permeability to protect the wound from external contamination and promote wound healing. As an ideal choice for dressing materials, the precise control of the fiber composition of plain spunlace nonwovens not only improves the liquid barrier properties of the dressing material, but also achieves micro-regulation of the environment around the wound by optimizing the arrangement of the fibers, which is conducive to wound healing and recovery.

In the surgical environment, the risk of cross infection mainly comes from the spillage and spread of pollutants such as blood and body fluids. Plain spunlace nonwovens achieve effective barrier to these pollutants by precisely controlling the type, proportion and arrangement of fibers, thereby significantly reducing the risk of cross infection. On the one hand, its good liquid barrier properties can effectively prevent the spillage and spread of pollutants; on the other hand, its excellent air permeability and softness can keep the surgical environment clean and comfortable, reducing the anxiety and discomfort of medical staff and patients.
