Description

Technical Field

[0001] The utility model relates to the technical field of spinning equipment, in particular to a weaving device for flash-spun spunlace non-woven fabrics. Background Art

[0002] Spunlace nonwoven fabrics are made by spraying high-pressure fine water streams onto one or more layers of fiber webs, so that the fibers are entangled with each other, thereby reinforcing the fiber web and giving it a certain strength. The resulting fabric is called spunlace nonwoven fabrics. Its fiber raw materials come from a wide range of sources, and can be polyester, nylon, polypropylene, viscose, chitin, microfiber, Tencel, silk, bamboo, wood pulp, seaweed, etc. In order to industrially produce spunlace nonwoven fabrics, corresponding nonwoven spunlace devices are usually used to process them. However, existing nonwoven spunlace devices are usually directly injected with high-pressure water sources, which increases the burden on the water pump, thereby affecting the durability and stability of the entire spunlace device. In addition, it is difficult to control the stacking thickness of the microfibers as needed when processing microfibers, and the spunlace device cannot be adjusted according to the stretching requirements of the nonwoven thickness, and the flexibility of use is poor.

[0003] In order to solve the deficiencies of the existing technology, people have conducted long-term exploration and proposed various solutions.

The filter box has a filtering mechanism, and the pressurizing box has a pressurizing mechanism that can increase the internal pressure.
