Embodiment 1

[0024] Such as Figure 1 to Figure 5 As shown, the present invention provides a production device for stretching non-woven fabrics in any direction, including a frame and a first matching roll 1, a first creasing forming roll 2 and a pressing roll 3 arranged on the frame, and the first matching roll 1 and the first creasing forming roll 2 are squeezed together, and the pressing roll 3 is squeezed with the first creasing forming roll 2 to form an extrusion bonding gap for the basic non-woven fabric 91 and the elastic film 92 to pass through. The outer peripheral side of the indentation forming roller 2 is provided with first forming protrusions 21, the first forming protrusions 21 are in the shape of a truncated cone, and the first forming protrusions 21 are distributed at equal intervals in the axial direction of the first indentation forming roller 2 and in the The circumferential direction of the first indentation forming roller 2 is equally spaced, and the spacing of the fi...

Embodiment 2

[0029] Such as Figure 6As shown, the difference between this embodiment and Embodiment 1 is that the pressing roller is replaced by the second indentation forming roller 4, and the outer peripheral side of the second indentation forming roller 4 is provided with a second forming protrusion 41, and the second forming protrusion 41 is in the shape of a circular platform, and one side of the second indentation forming roller 4 is provided with a second mating roller 5, and the outer peripheral side of the second mating roller 5 is provided with a circular second mating groove, and the second mating groove is connected with the first mating groove. The two forming protrusions 41 correspond one-to-one, and the second matching groove and the second forming protrusion 41 squeeze each other so that the basic non-woven fabric is tensioned on the outer periphery of the upper second creasing forming roller 4, and the basic non-woven fabric 91 is tightened. The part of the top surface of...

Embodiment 3

[0034] Such as figure 1 and Figure 5 As shown, the present invention also provides a random stretch non-woven fabric 9, including a basic non-woven fabric 91 and an elastic film 92, and the basic non-woven fabric 91 is passed through the random stretch non-woven fabric production device described in Embodiment 1. The first cooperating roll 1 and the first indentation forming roll 2 are extruded to form a structure with a flat part 911 and evenly distributed natural bulges 912, and the flat part 911 and the elastic film 92 are extruded by the smooth roll and the first indentation forming roll Pressure bonding. The nonwoven fabric 9 stretched in any direction in this embodiment can obtain uniform good elasticity in any direction.

[0035] For other content not described in this embodiment, reference may be made to Embodiment 1.

Abstract

The invention discloses an arbitrary-direction stretching non-woven fabric production device, belongs to the field of non-woven fabric production, and solves the problem that in the prior art, a telescopic composite sheet does not have excellent elasticity in any direction. According to the technical scheme for solving the problem, first forming protrusions are arranged on the side face of the periphery of a first indentation forming roller, each first forming protrusion is in a circular truncated cone shape, circular first matching grooves are formed in the side face of the periphery of a first matching roller, the first matching grooves and the first forming protrusions extrude each other so that a basic non-woven fabric can be tensioned on the periphery of the first indentation forming roller, flat parts are formed on the portions, tightly attached to the top end faces of the first forming protrusions, of the basic non-woven fabric, natural bulges which are evenly distributed are formed on the portions, located between the adjacent first forming protrusions, of the basic non-woven fabric, and extrusion bonding gaps are located between the top end faces of the first forming protrusions and a press-fitting roller and enable the flat parts to be bonded with an elastic film. The device is mainly used for producing the arbitrary-direction stretching non-woven fabric. The invention further provides an arbitrary-direction stretching non-woven fabric.

Description

technical field [0001] The invention relates to the field of non-woven fabric production, in particular to a production device for stretching non-woven fabric in any direction and the non-woven fabric for stretching in any direction produced therewith. Background technique [0002] In the prior art, in order to obtain a non-woven fabric composite sheet with elasticity in multiple directions, after the non-woven fabric with excellent elasticity in the width direction (direction perpendicular to the flow direction and the thickness direction) is laminated with the elastic sheet, Both direction and flow direction can produce a stretchable composite sheet with excellent elasticity, such as the invention patent application 201980010818.2. However, this composite sheet not only requires the elastic direction of the nonwoven fabric used, but also does not have excellent elasticity in any direction. Contents of the invention [0003] The object to be achieved by the present inven...
