Description

Technical Field

[0001] The invention relates to the technical field of spunlace nonwoven fabric production, in particular to a spunlace nonwoven fabric composite processing technology. 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 webs. The resulting fabric is called spunlace nonwoven fabrics. The fiber raw materials processed by the spunlace method are of a wide variety, including polyester, nylon, polypropylene, viscose, etc. The principle of reinforcing fiber webs by spunlace is similar to that of acupuncture, but needles are not used. Instead, a spunlace machine that can generate multiple fine water jets through high pressure is used to spray the fiber webs. After the water jets pass through the fiber webs, they are supported by the net curtain and rebound, and then penetrate the fiber web again, so that the fibers in the fiber webs are displaced, interlaced, entangled, and embraced under the hydraulic action of high-speed water jets in different directions, thereby reinforcing the fiber webs. The traditional spunlace process for processing composite nonwoven fabrics is mostly a multi-layer composite reinforcement of the same type of fiber webs. The composite fabrics obtained have relatively simple functions and touch. In the field where there is a certain demand for the strength and comfort of the fabrics, the performance of the composite spunlace nonwoven fabrics obtained by the existing technology cannot meet the use requirements.

[0003] In addition, when hydroentanglement is performed on spunlace nonwoven fabrics, two layers of fiber webs need to be stacked together first and then placed in a hydroentanglement machine for hydroentanglement forming. If the fibers are wrinkled and offset during the stacking process, it is easy to cause deviations in the fiber stacking position, affecting the forming quality of the composite spunlace nonwoven fabric.
