When making PLA non-woven fabric, a template is made according to a certain specification and the role of the template is to predetermine the fiber path and shape. In this process, precise calculations and templates must be made to ensure that the fibers can flow according to the predetermined path.
Swap the tow as per the template requirements, ie, swap the polyester fiber to the desired tow type and number. In this process, it is necessary to pay attention to the type and quality of the tow to avoid problems such as mismatch or poor quality.
In the process of making PLA non-woven fabric, heat setting is done after spinning, that is, the spinning liquid is discharged through the spinneret hole and cured on the heating plate. This process must pay attention to the temperature and pressure of the heating plate and the flow rate and speed of the fiber to ensure the quality and performance of the non-woven fabric. At the same time, it is also necessary to avoid blockages and other situations.
Finally, the non-woven fabric that has been cured is wound and packaged for further use. This process must pay attention to the quality and integrity of the non-woven fabric to avoid problems such as damage or contamination.
The main parameters that need attention in the operation process include temperature, pressure, traction speed, etc. Temperature is an important factor affecting fiber cure, pressure can control fiber flow and shape, and traction speed determines fiber speed and path. Precise control of these parameters can ensure the quality and performance of non-woven fabrics.
With the continuous progress of science and technology, the production process of PLA non-woven fabric is also continuously developing. In the future, the production process of PLA non-woven fabric will be more environmentally friendly, efficient and intelligent. Specifically, the following aspects will guide future development:
Production Process Optimization: In the future, PLA non-woven fabric production process flow and parameter control will be further optimized to improve the quality and performance of non-woven fabric. At the same time, new production process methods are developed to meet the needs of different sectors.
Material cost reduction: In the future, the production cost of PLA non-wovens will be reduced by developing new biological resources or by optimizing production processes and other methods to improve market competitiveness.
Intelligent Manufacturing Equipment: Achieving automation and remote control of future manufacturing processes will strengthen the intelligent development and application of manufacturing equipment to improve manufacturing efficiency and product quality.
