Problems solved by technology

However, in the above-mentioned process, it is easy to appear that the melted hot-melt fibers stick to each other into sheets or strips. After cooling, these sticky areas will form hard lumps on the non-woven fabric, which not only affects the The feel of the non-woven fabric, and the formed hard area will greatly affect the softness and water absorption performance of the non-woven fabric, resulting in a decrease in the performance of the non-woven fabric

Embodiment Construction

[0016] See figure 1 As shown, the composite non-woven fabric consolidation equipment 100 provided by the first embodiment of the present invention is used to consolidate the non-woven fabric fiber composite body 200, and the non-woven fabric fiber composite body 200 includes the first hot-melt fiber layer 210 and a hydrophilic fiber layer 220 stacked under the first heat-melt fiber layer 210 . The composite non-woven fabric consolidation device 100 includes a supporting mesh curtain 10 , a hot air source 20 , a plurality of injection ports 30 and a vacuum device 40 .

[0017] The supporting net curtain 10 is used to support the non-woven fiber composite 200 and transport it at a certain speed, so as to facilitate the consolidation of the non-woven fiber composite 200 by the composite non-woven consolidation device 100 Knot handling.

[0018] It can be understood that, in the present invention, the supporting mesh curtain 10 may be a part of the nonwoven fabric manufacturing ...

Abstract

The invention relates to a solidifying device for composite non-woven fabrics and is used for solidifying a non-woven fabric fiber composite body. The non-woven fabric fiber composite body comprises a first hot melt fiber layer and a hydrophilic fiber layer overlapped under the first hot melt fiber layer. The solidifying device for the composite non-woven fabrics comprises a hot air source and an injection orifice, wherein the hot air source is used for supplying pulse hot air, the injection orifice is communicated with the hot air source and used for enabling the pulse hot air to pass through so as to form at least one beam pulse hot gas jet which is used for performing jet impact on the non-woven fabric fiber composite body so as to soften hot melt fibers of the first hot melt fiber layer, and the softened hot melt fibers are brought into the hydrophilic fiber layer to form solidifying points. The invention further relates to a solidifying process for the composite non-woven fabrics.

Description

technical field [0001] The invention relates to a composite non-woven fabric consolidation equipment and process. Background technique [0002] Most high molecular polymer materials are hot-melt, that is, they will soften and melt after being heated to a certain temperature, and become a viscous fluid with a certain fluidity, and then solidify again after cooling to become a solid. The thermal bonding non-woven process is to use this characteristic of the hot-melt polymer material to soften and melt part of the fiber or hot-melt powder after the fiber web is heated, and produce adhesion between the fibers. After cooling, the fiber web is strengthened and becomes a thermal bond. Composite nonwoven materials. Currently widely used thermal bonding processes mainly include hot-melt bonding, hot-roll bonding and ultrasonic bonding, among which hot-melt bonding and hot-roll bonding are the most widely used. [0003] The hot-melt bonding method generally adopts the method of hot ...
