Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric technology, specifically to a nonwoven fabric with a dustproof structure. Background Technology

[0002] Non-woven fabric, also known as non-woven cloth, needle-punched cotton, and needle-punched non-woven fabric, is made of polyester fiber and is produced through a needle-punching process. It can be made in different thicknesses, feels, and hardnesses. Non-woven fabric is moisture-proof, non-toxic, odorless, inexpensive, and recyclable, and can be used in various industries.

[0003] The dustproof ability of conventional nonwoven fabrics mainly comes from their fiber structure. Conventional nonwoven fabrics include spunlace nonwoven fabrics, spunbond nonwoven fabrics, and needle-punched nonwoven fabrics. Nonwoven fabrics are nonwoven fabrics made by bonding fibers through mechanical, chemical, or thermal methods. There are certain gaps between the fibers. These gaps can block some dust and particulate matter, but their dustproof effect is relatively weak. Based on this, a nonwoven fabric with a dustproof structure is proposed. Utility Model Content
