When making PLA non-woven fabrics, a template is made according to a certain specification, and the role of the template is to preset the path and shape of the fiber. In this process, precise calculations and templates need to be designed to ensure that the fibers can flow according to the preset path.
Swap the tow according to the requirements of the template, that is, swap the polyester fiber into 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 mismatching or substandard quality.
In the process of making PLA non-woven fabric, heat setting is carried out after spinning, that is, spinning liquid is discharged through the spinneret hole and cured on the heating plate. This process needs to 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 blockage and other situations.
Finally, the non-woven fabric that has been cured is wound and packaged for subsequent use. This process needs to pay attention to the quality and integrity of non-woven fabrics to avoid problems such as damage or pollution.
The main parameters that need to be paid attention to in the operation process include temperature, pressure, traction speed, etc. The temperature is an important factor affecting the fiber curing, the pressure can control the flow and shape of the fiber, and the traction speed determines the speed and path of the fiber. The 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 fabrics is also constantly developing. In the future, the production process of PLA non-woven fabrics will be more environmentally friendly, efficient and intelligent. Specifically, the following aspects will be the direction of future development:
Optimization of production process: In the future, the production process flow and parameter control of PLA non-woven fabrics will be further optimized to improve the quality and performance of non-woven fabrics. At the same time, new production process methods are developed to meet the needs of different fields.
Reduction of material cost: In the future, the production cost of PLA non-wovens will be reduced by developing new biological resources or optimizing the production process and other methods to improve its market competitiveness.
Intelligent production equipment: The future will strengthen the intelligent development and application of production equipment, to achieve automation and remote control of the production process, improve production efficiency and product quality.
