Embossing device and embossing process, composite non-woven fabric absorber, production device and process thereof

Abstract

The present invention relates to an embossing device, which comprises a first embossing roller and a second embossing roller, wherein the two embossing rollers are mutually cooperated, and the surface of at least one of the two embossing rollers is provided with embossing patterns. The first embossing roller further comprises a first hot air source and a first housing sleeved around the first hot air source, wherein the first hot air source has a first air outlet for outputting hot air gas to the outside. The first housing is provided with a first injection port corresponding to the first air outlet. When the first injection port rotates and reaches a position coinciding with the first air outlet, the hot air provided by the first hot air source is injected from the first ejection port to form at least a bunch of hot air jet. The present invention further relates to a process for carrying out embossing by using the embossing device, a composite non-woven fabric absorber production device comprising the embossing device, a composite non-woven fabric absorber production process and composite non-woven fabric absorber products.

Description

technical field [0001] The invention relates to an embossing device, a process, and a composite non-woven absorber production device, a process and a composite non-woven absorber product comprising the embossing device. 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 b...

AI Technical Summary

Problems solved by technology

[0004] In the existing production process, no matter whether the above-mentioned hot-melt method or hot-press method is used to produce the composite non-woven absorbent body, it is easy to cause the melted hot-melt fibers to stick to each other during the processing process. The phenomenon of banding, so that hard blocks are formed in the hot-melt area or hot-pressed area of ​​the composite non-woven fabric absorbent body. Absorbent softness and water absorption

In addition, when embossing is required on the surface of the above-mentioned composite non-woven fabric absorber, special embossing equipment needs to be added to carry out, the process is cumbersome, and the cost investment is relatively large.
