Description

Technical Field

[0001] The utility model relates to the technical field of sanitary napkin production, in particular to a novel non-woven fabric cutting device. Background Art

[0002] Non-woven fabrics, also known as non-woven fabrics, needle-punched cotton, and needle-punched non-woven fabrics, are made of polyester fiber and polyester fiber. They are made through a needle-punching process and can be made into different thicknesses, feels, and hardness. Non-woven fabrics have no warp and weft, so they are very convenient to cut and sew. They are also light and easy to shape because they do not require textile gauze. Instead, they are made by directional or random arrangement of textile staple fibers or filaments to form a fiber mesh structure, which is then reinforced by mechanical, thermal bonding, or chemical methods. Non-woven fabrics are made of polyester, polypropylene, cotton, spandex, acrylic, etc. according to their composition. The surface layer of pure cotton sanitary napkins is made of pure cotton material. Its main material is pure cotton non-woven fabric. Pure cotton non-woven fabric is made of natural fiber pure cotton. The cotton is opened and loosened, and the pure cotton is arranged into a net using a cutting-edge carding machine, a web laying machine and a stretching machine. The high-density and numerous needle-shaped water columns formed after pressure are used to promote the entanglement of cotton fibers into cloth through a water spunlace machine. It only takes five minutes from raw cotton to finished cloth, which saves the spinning and weaving links compared to traditional woven fabrics, shortens working hours, and saves a lot of energy consumption, labor and equipment.
