Have you ever experienced that your clothes shrank or became wrinkled after putting them in the dryer? The dryer dries clothes by blowing hot air, but the fibers in the fabric can deform or shrink due to the heat, resulting in the entire garment shrinking or wrinkling. Similarly, non-woven fabrics, which are also made of fibers, can also shrink or deform when heated. In this article, we will explain the reasons why fibers shrink and deform due to heat, using non-woven fabrics as an example, as well as methods to suppress the shrinkage and deformation of fibers caused by heat. *For more detailed information, please refer to the related links.

Separation membranes are essential in fields such as water treatment and healthcare, but the strength of the membranes themselves is very weak. Therefore, the presence of a support structure that enhances physical strength by supporting the separation layer is indispensable for them to function effectively. Non-woven fabric has played an important role as this support structure, but conventional technologies have faced the challenging issue of balancing pore size adjustment with ensuring strength and thickness. This article will provide a detailed overview of separation membranes and the necessity of support structures, while also explaining in detail the newly developed heterogeneous double-layer non-woven fabric as a technology to address the challenges of current support structures. *For more detailed information, please refer to the related links.

The "pore diameter" in wet non-woven fabric (non-woven fabric produced by the paper-making method) is a very important factor in product performance and quality control. For example, in filter and separator applications, the size of the pores in the sheet affects the separation performance, so it is necessary to appropriately design and manage the pore diameter to meet the specified performance. On the other hand, the functional requirements for non-woven fabrics are becoming increasingly sophisticated, and there are challenges in traditional technology to adjust to the desired pore diameter while ensuring the strength and thickness of the sheet. This column will provide a broad explanation of the important pore diameter for enhancing the functionality of wet non-woven fabrics, covering everything from basic concepts to control technologies in the manufacturing process, the impact on product performance, as well as application examples and future prospects, in a way that is easy to understand for those who are not specialists in wet non-woven fabric technology. *For detailed content of the column, please refer to the related links.
