In the production process of non-woven fabrics, the high-speed cross-lapper, as the core equipment, bears the heavy responsibility of evenly spreading the fiber raw materials into the fiber web. However, during the web laying process, the deviation of the leather curtain has always been one of the k...

1. Working principle of air-laid machine and fiber dispersion mechanismThe working principle of air-laid machine is based on the fluidity and distribution characteristics of fiber raw materials under the action of high-speed airflow. During the mixing and forming process, the fiber raw materials are...

Pretreatment of non-woven fabric substrate is the first step in the production of three-dimensional molded sound insulation felt, and it is also the key to ensure the quality of the final product. The pretreatment process mainly includes the steps of fiber opening, mixing, combing and substrate shap...

Heat setting is one of the core processes of the room-temperature PTFE filter felt production line in non-woven production equipment. This process precisely controls the heating temperature and duration to treat the pre-pretreated plain felt at high temperature to achieve the desired setting effect....

In the production process of non-woven fabrics, the spunlace process is undoubtedly the most critical link. It uses high-pressure water flow to spray the fiber web, and through the action of physical force, the fibers form a tight and stable connection, thus giving the non-woven fabric excellent phy...

The core of the independent tension function of the high-speed slitting machine is that each winding arm is equipped with an independent tension control system. This system consists of a high-precision tension sensor, an intelligent controller and an actuator, which can monitor and adjust the materi...
