Embodiment Construction

[0011] like figure 1 It is the process flow chart of the present invention, a processing technology of composite non-woven fabric, the non-woven fabric surface layer 1 is introduced between the convex roller 2 and the concave roller 3 with concave-convex patterns and the contact surfaces mesh with each other, and the convex roller 2 to pressurize, and the extruded non-woven fabric surface layer 1 with concave-convex pattern is driven by the concave roller 3 and the non-woven fabric bottom layer 4, and then passes through the contact surface of the shaping hot roll 5 and the convex point on the concave roller 3 Compound together, and carry out pressure on the sizing hot roll 5. Composite composite non-woven fabrics such as figure 2 As shown, the non-woven fabric surface layer 1 and the non-woven fabric bottom layer 4 are combined together, the non-woven fabric surface layer 1 shows a concave-convex effect, and there is a hollow layer 6 between the non-woven fabric surface lay...

Abstract

The invention relates to the technical field of nonwoven fabrics, and in particular relates to a processing technology of a composite nonwoven fabric. The composite nonwoven fabric adopts a nonwoven fabric surface layer and a nonwoven fabric bottom layer and comprises the following steps in sequence: feeding the nonwoven fabric surface layer between a convex roll and a concave roll, wherein the convex roll and the concave roll are respectively provided with concave and convex patterns and are engaged to each other by contact surfaces; pressurizing the convex roll; driving the pressed nonwoven fabric surface layer with the concave and convex patterns by the concave roll to combine with the contact surfaces of convex points on the concave roll together with the nonwoven fabric bottom layer through a sizing hot roll; and pressurizing the sizing hot roll. The composite nonwoven fabric with the concave and convex patterns produced by the processing technology provided by the invention can be coated on the baby diaper and feminine napkin, therefore, the contact area between the nonwoven fabric and the skin is greatly reduced, and the comfort is improved; the surface area is increased, so that the effect of absorbing liquid is greatly improved; grooves formed by the concave and convex patterns are beneficial for guiding the liquid; and hollow bulges are generated and can highly keep the nonwoven fabric dry.

Description

technical field [0001] The invention relates to the technical field of non-woven fabrics, in particular to a processing technology of composite non-woven fabrics. Background technique [0002] As a new generation of environmentally friendly materials, non-woven fabrics have been widely used in various industries due to their soft texture, light weight and low price. However, non-woven fabrics currently used The large contact area with the skin leads to poor comfort, the liquid is not easy to divert, and the dry performance is poor. Contents of the invention [0003] In order to overcome the deficiencies of the existing technology, the invention provides a processing technology of composite non-woven fabric. [0004] The technical solution adopted by the present invention to solve the technical problem is: a processing technology of composite non-woven fabric, comprising a non-woven fabric surface layer and a non-woven fabric bottom layer, introducing the non-woven fabric ...
