Problems solved by technology

Repeated fiber web transfers lead to long production lines and low production efficiency. At the same time, pulp is likely to remain on the felt, making the thickness of the non-woven fabric uneven, affecting its air permeability and uniformity, and even small holes visible to the naked eye.

Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] Such as figure 1 The shown wet process manufacturing device includes a raw material trough 1, a cage roll 2, a suction roll 3, a polyester mesh belt 4, a work roll 5, a drying cylinder 6, a winding roll 7, and a dehydration device 8. Wherein the work rolls include 5a, 5b, 5c and so on.

[0020] The shown polyester mesh belt 4 turns around and between the work rolls 5a, 5b, 5c and the suction roll, any one of which is set as a power roll, so that the polyester mesh belt 4 can turn around in the counterclockwise direction. This device replaces the complex web forming equipment in the prior art by directly setting the mesh cage roller 2 in the raw material tank 1, shortening the production process and production line. Contact with the polyester mesh belt 4 under rotation, and the negative pressure environment in the suction roller 3 ensures that the fiber web c...

Abstract

The invention discloses a wet-process non-woven fabric manufacturing method. The wet-process non-woven fabric manufacturing method sequentially comprises a web-forming procedure, a vacuum-transferring procedure and a drying procedure of a sizing agent. The web-forming procedure comprises that the sizing agent is adhered on a mesh cage roller to form a fibre web. The vacuum-transferring procedure comprises that a vacuum-transferring roller matched with the mesh cage roller transfers the fibre web to a polyester mesh belt through vacuum suction, wherein the polyester mesh belt is wound around multiple working rollers and the vacuum-transferring roller. The wet-process manufacturing method and the manufacturing equipment which are applicable to 15 - 150 g / m2 non-woven fabric are provided. According to the wet-process non-woven fabric manufacturing method and the manufacturing equipment, a felt is no longer used, and meanwhile the whole production line is shortened.

Description

technical field [0001] The invention relates to a method and equipment for manufacturing wet-laid non-woven fabrics, in particular to the manufacture of 15-150 g / ㎡ non-woven fabrics. Background technique [0002] In the conventional manufacturing process of wet spunlace nonwoven fabrics, in the wet forming process, raw material fibers and water are simultaneously supplied to a mesh conveyor belt for a specified purpose to form a fiber web, and the felt is in contact with the aforementioned mesh conveyor belt. , due to the difference in surface roughness between the aforementioned wire mesh conveyor belt and the felt, once the fiber web on the wire mesh conveyor belt is transferred to the felt, the fiber web will be transferred to the fiber interlacing process by the felt. For example, patent CN99119106.4 is representative of this type of technology. This type of method can be realized for relatively thick non-woven fabrics, and the residual slurry on the felt has little infl...
