For different application fields, adjust the fiber ratio and process parameters of Spunlace Nonwoven Fabric (spunlace nonwoven fabric) to optimize its performance, mainly need to consider the following key aspects:
1. Fiber ratio adjustment
Chemical fiber staple fiber:
According to the requirements of strength and stability in the application field, the proportion of chemical fiber staple fibers such as polyester and nylon can be adjusted. For example, in the field of medical supplies, such as surgical gowns, masks, etc., higher strength and stability are required, so the proportion of fibers such as low melting point polyester and low melting point polyester can be increased.
For application fields that require softness and comfort, such as clothing, household goods, etc., the proportion of chemical fiber staple fibers can be appropriately reduced and the proportion of natural fibers can be increased.
High elastic fiber:
For application fields that require good elasticity, such as clothing, automotive interiors, etc., the proportion of high elastic fibers can be increased to improve the elasticity of spunlace nonwoven fabrics.
Other fibers:
According to specific needs, fibers with specific properties, such as antibacterial fibers, flame retardant fibers, etc., can be added to enhance the functionality of spunlace nonwoven fabrics.
2. Adjustment of process parameters
Spunlace pressure:
According to the fiber type and fiber ratio, adjust the water pressure and spray time during the spunlace process. Higher water pressure and longer spray time can increase the degree of interweaving between fibers and improve the strength and stability of spunlace nonwovens.
Fiber web thickness:
Adjust the thickness of the fiber web according to the needs of the application field. Thicker fiber webs can provide better filtration performance and strength, but may affect softness and comfort; thinner fiber webs are softer and more comfortable, but may sacrifice some strength and filtration performance.
Drying temperature and time:
The drying process is crucial to the stability and mechanical properties of spunlace nonwovens. According to the fiber type and fiber ratio, adjust the drying temperature and time to ensure that the spunlace nonwovens achieve the performance during the drying process.
Other process parameters:
According to needs, process parameters such as fiber pretreatment, mixing, and fiber web forming can also be adjusted to further optimize the performance of spunlace nonwovens.
In summary, adjusting the fiber ratio and process parameters of Spunlace Nonwoven Fabric requires comprehensive consideration of multiple factors such as application field, fiber type, fiber ratio, and process parameters. Through reasonable adjustment and optimization, spunlace nonwoven fabrics with performance can be prepared to meet the needs of different fields.
