Meltblown non-woven fabric is a material commonly used in medical supplies such as masks and protective clothing, and its toughness and tensile strength are crucial to the quality of the product. This article will explore how to improve the toughness of meltblown fabrics from the aspects of material selection, process optimization, and quality control, so that they are not easily pulled apart.
Choose high-quality raw materials
1.1 Understand the composition of melt blown non-woven fabric
Melt blown non-woven fabrics are usually composed of polypropylene fibers, which have good melt and plasticity.Understanding the composition of meltblown non-woven fabric is helpful in selecting high-quality raw materials and improving the toughness of meltblown fabric.
1.2 Selecting appropriate fiber materials
Polypropylene fiber is the main raw material for melt blown non-woven fabrics, but different types of polypropylene fibers have different properties.Choosing polypropylene fibers with high tensile strength and toughness can improve the toughness of meltblown fabrics.
Optimize the melt spraying process
2.1 Control the melt spraying temperature
The melt blown temperature is an important factor affecting the toughness of melt blown fabrics, and excessively high or low temperatures can lead to a decrease in the toughness of melt blown fabrics.
By controlling the melt spraying temperature reasonably, the toughness of the melt spraying fabric can be improved, making it less prone to breakage.
2.2 Adjusting the melt spraying speed
The melt spraying speed also has a certain impact on the toughness of the melt spraying fabric, as too fast or too slow a speed can lead to a decrease in the toughness of the melt spraying fabric.By adjusting the meltblown speed, better toughness of meltblown fabric can be obtained, and the quality of the product can be improved.
Strengthen quality control
1. Strictly control the thickness of the meltblown fabric
The thickness of meltblown non-woven fabric is an important factor affecting its toughness, and excessively thick or thin meltblown fabric can lead to a decrease in toughness. By strictly controlling the thickness of the meltblown fabric, its toughness can be improved, making it less prone to breakage.
2. Test the tensile strength of meltblown fabric
Tensile strength is an important indicator for evaluating the toughness of meltblown fabrics. By detecting the tensile strength of meltblown fabrics, problems can be identified and adjusted in a timely manner. Strengthening the testing of the tensile strength of meltblown fabrics can help improve product quality and ensure that they are not easily broken.
Conclusion
By selecting high-quality raw materials, optimizing melt blown processes, and strengthening quality control, the toughness of melt blown non-woven fabrics can be effectively improved, making them less prone to breakage. This not only helps improve the quality of medical supplies such as masks and protective clothing, but also enhances the user experience and protects people’s health and safety. In the future development, we should constantly explore innovation, further improve the toughness of meltblown fabrics, and make greater contributions to the field of medical protection.
