The main components of spunlace equipment and their main functions

The spunlace non-woven fabric manufacturing system is mainly composed of a pre-humidifier, a spunlace head, a conveyor screen, a dewatering device, a drying device and a water treatment system. 1. Spunlace head The spunlace head is one of the main components that produce high-pressure cluster water flow. It is composed of a water inlet tube cavity with water inlet channels inside, a lower water jet plate and a high-pressure sealing device (. The spunlace head adopts high-quality Made of stainless steel. High-pressure water is introduced into the upper water cavity, namely the dynamic water cavity, through the water inlet pipe on the side of the water spray cavity, and then enters the lower water cavity evenly from the equalizing hole. The lower water cavity is also called the equalizing cavity, that is, the static water cavity. After the flow, the water flow in the spunlace head system is more evenly distributed to ensure the consistency of the quality of the water jet. The high-pressure water is jetted to the fiber net through the small holes on the water spray plate, so that the fiber net absorbs the water needle energy and is consolidated 2. Conveyor curtains Conveyor curtains are woven with high-strength polyester or polyamide filaments according to the required mesh specifications, and some are made of stainless steel wires, which are generally made by weaving. Its functions are as follows (1) Support Hold and transport the fiber web into the spunlace area. (2) During the spunlace, the net curtain reflects the high-pressure water needle and participates in the fiber web reinforcement. (3) It can effectively filter water and exhaust. (4) Through the net curtain structure The mesh number and pattern change of the finished product can make the finished product form a certain appearance effect. (2) The net curtain structure is generally made of high-strength polymer material. The net curtain of the rotary drum spunlace machine adopts It is composed of multi-layer structure, the outer layer is made of impact-resistant metal nickel microporous round net or woven wire mesh with larger mesh, and the inner layer is multi-layer woven wire mesh, the mesh number gradually decreases from the outside to the inside. (1) Adopted The net curtain of a certain organization specification makes the product form the same grid structure as the net curtain. (2) Some processes add a jacquard spunlace device after the conventional spunlace, that is, use a rolling cylinder ( Rolling jig). The material of the roller is metallic nickel, and the pattern on the surface of the jig is made by photographic engraving. The spunlace head is installed in the jig, and the high-pressure water needle passes through the pattern holes on the roller to copy the pattern on the web.
