Abstract
Description
Technical Field
[0001] This application relates to the field of nonwoven fabric processing technology, and in particular to a calendering device for antibacterial nonwoven fabric. Background Technology
[0002] Nonwoven fabrics have wide applications in numerous fields such as medical and health, packaging, clothing, home furnishings, and automobiles. For example, in the medical and health field, they are used for surgical gowns and masks, requiring good barrier properties and comfort; in the packaging field, they are used for shopping bags, requiring a certain level of strength and flexibility. As various industries continuously raise their performance requirements for nonwoven fabrics, they drive continuous innovation and development in nonwoven fabric production technology. In nonwoven fabric production, calendering machines primarily further compact and flatten the initially formed nonwoven fabric, making the fibers more tightly bonded and improving the appearance and performance of the nonwoven fabric.
[0003] In the existing technology, calenders generally consist of two or more rollers arranged in a certain form, which press the material at a certain temperature, so that the material is subjected to compression and stretching as it passes through the rotating rollers.
[0004] Regarding the aforementioned technologies, the inventors believe that during the operation of calendering equipment, impurities such as fiber debris and dust will accumulate. These impurities may mix into the nonwoven fabric during the calendering process, causing surface defects, spots, and other problems, thus reducing the quality of the nonwoven fabric. Utility Model Content
[0005] The purpose of this application is to provide a calendering device for antibacterial nonwoven fabrics to improve the problem of accumulation of impurities such as fiber debris and dust during the operation of the calendering device.
