Production equipment of compound non-woven fabric absorber, process and compound non-woven fabric absorber

Abstract

The invention relates to production equipment of compound non-woven fabric absorber, which comprises a transmission unit, a lapping unit and a consolidating unit. The lapping unit is used to form a non-woven fabric fiber compound on the transmission unit and the non-woven fabric fiber compound is formed by at least a first thermally melting fiber layer and a hydrophilic fiber layer that are laminated. The transmission unit is used to transmit the non-woven fabric fiber compound in a predetermined transmission direction. the consolidating unit is used to provide at least a pulse hot air which is used to spray and impact the non-woven fabric fiber compound so as to soften the thermally melt fiber of the first thermally melting fiber layer and introduce the softened thermally melt fiber into the hydrophilic fiber layer so as to form consolidating points. The invention further relates to a preparation process of the compound non-woven fabric absorber and the compound non-woven fabric absorber.

Description

Technical field [0001] The invention relates to a composite non-woven fabric absorber production equipment, a process and a composite non-woven fabric absorber. Background technique [0002] High-molecular polymer materials are mostly hot-melt, that is, they will soften and melt when heated to a certain temperature, and become a viscous fluid with a certain fluidity. After cooling, they will re-solidify and become a solid. The thermal bonding nonwoven process uses this characteristic of hot-melt polymer materials to soften and melt part of the fiber or hot-melt powder after the fiber web is heated, resulting in adhesion between the fibers. After cooling, the fiber web is reinforced to become a hot adhesive. He non-woven materials. The currently widely used thermal bonding processes mainly include hot melt bonding, hot rolling bonding and ultrasonic bonding, among which hot melt bonding and hot rolling bonding are the most widely used. [0003] The hot-melt bonding method generall...

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 striping, so that hard blocks are formed in the hot-melt area or hot-pressed area of ​​the composite non-woven fabric absorbent. The softness and water absorption performance of the absorbent body will lead to a decrease in the performance of the composite non-woven fabric absorbent body.
