Description
Technical Field
The invention discloses a production method of filament spunbonded non-woven fabric, relates to the technical field of non-woven fabric production and manufacturing, and particularly relates to a production method of filament spunbonded non-woven fabric without a pre-pressing roller or with an auxiliary air suction area.
Background
A lapper is one of the important equipment in the production line of spunbond nonwovens. The lapping machine has the main functions of uniformly lapping the fibers from the previous process and effectively and smoothly conveying the uniformly lapped fiber web to the next process. At present, on a production line of spun-bonded non-woven fabrics, when a fiber web passes through a lapping machine, the fiber web is attached to the lapping machine through lower air suction of a main air suction area of the lapping machine, a pre-pressing roller is required to be arranged behind the main air suction area of some lapping machines, and the fiber web pre-pressed by the pre-pressing roller enters consolidation equipment. The other lapping machine is provided with an auxiliary air suction area behind a main air suction area of the lapping machine, and enters the consolidation equipment after passing through the auxiliary air suction area. If the lapping machine is not provided with the prepressing roller or the auxiliary air suction area, the ambient air at the downstream of the lapping machine can be sucked to the main air suction area due to the air suction of the main air suction area, and the wind direction of the ambient air is opposite to the running direction of the fiber web, so that the fiber web on the lapping machine is easily influenced by reverse wind to turn over the web.
The pre-pressing roller is used for pre-shaping the disordered and fluffy fiber web under the action of a certain temperature, and then the fiber web is conveyed to the next procedure for consolidation through the front guiding device under the traction of the main transmission device, so that the fiber web is not easy to turn over due to reverse wind after being pre-pressed. However, by adopting the pre-pressing roller mode, static electricity is easily generated due to the friction effect when the tows run at a high speed, net turning can be caused, the product quality is influenced, the rollers are easily wound after the net turning and the static electricity are generated, and the rollers need to be cleaned by operators after the rollers are wound, so that the continuous production of equipment is influenced, and the production reduction is caused; in order to solve the problem, a static eliminator is generally added at the front and the back of the prepressing roll, but static electricity can not be completely eliminated, roll winding phenomenon caused by static electricity can occur, and roll winding phenomenon can only be manually eliminated by an operator in actual production, so that normal production is influenced. In addition, the pre-pressing roller of the lapping machine is high-temperature rotating equipment, and potential safety hazards also exist when workers frequently remove roller winding operation.
The auxiliary air suction area is arranged behind the main air suction area of the fiber web, so that the phenomenon of net turning can be reduced, but the net turning can not be completely eliminated due to the balance of environmental shadow and wind which is not easy to control, and the higher the production speed is, the more serious the net turning is, and the static eliminator can not eliminate static electricity.
In view of the above problems in the prior art, it is necessary to develop a new method for producing a filament spunbonded nonwoven fabric, so as to overcome the problems in the prior art.
