Embodiment 1

[0058] In this embodiment, the fluffy nonwoven fabric layer 13 is cut into three fluffy nonwoven fabric strips. Wherein, take the fluffy nonwoven fabric strip 13b located in the longitudinal midline region as the reference fluffy nonwoven fabric strip 13b, and respectively apply a reference tensile force to the two longitudinal ends of the reference fluffy nonwoven fabric strip, and the tensile force passes through the adjustment line The speed is achieved by making the loose nonwoven fabric deform and narrow in the width direction. Specific steps are as follows:

[0059] Step 1. Set the reference line speed of the fluffy nonwoven fabric strip 13b, whose width ratio is 80%.

[0060] Step 2. Set the fluffy nonwoven fabric strips 13a and 13c on both sides of the reference fluffy nonwoven fabric strips, adjust the line speed, and the width ratio is 80%.

[0061] Narrowing through the above-mentioned differential stretching, the fluffy nonwoven fabric 13a is deformed with refere...

Embodiment 2

[0064] In this embodiment, between the fluffy nonwoven fabric strip 13a, the reference fluffy nonwoven fabric strip 13b, and between the fluffy nonwoven fabric strip 13b and the fluffy nonwoven fabric strip 13c, different proportions of deformations are produced in the width direction, Narrowing, forming a ladder-like linear velocity relationship between the reference fluffy nonwoven fabric strip and the fluffy nonwoven fabric layer measurement boundary. Therefore, the difference between the present embodiment and embodiment 1 is only that the reference line speed of the reference fluffy nonwoven fabric strip 13b in this embodiment, the fluffy nonwoven fabric strips 13a, 13c located on both sides of the reference fluffy nonwoven fabric strip The aspect ratio (line speed) setting is different.

[0065] Step 1. Set the reference line speed of the fluffy nonwoven fabric strip 13b, whose width ratio is 80%.

[0066] Step 2. Set the line speed of the fluffy non-woven fabric strips...

Embodiment 3

[0069] The difference between the present embodiment and embodiment 1 is only that the present embodiment refers to the reference line speed of the fluffy nonwoven fabric strip, and the width ratio (line speed) of the fluffy nonwoven fabric strip on both sides of the reference fluffy nonwoven fabric strip. speed) settings are different.

[0070] Step 1. Set the reference line speed of the fluffy nonwoven fabric strip 13b, whose width ratio is 80%.

[0071] Step 2. Set the line speed of the fluffy non-woven fabric strips 13a, 13c, and their width ratios are both 70%.

[0072] The flow-guiding permeable through-holes 105, 106 greatly enhance the flow-guiding effect of the composite absorbent core. The diversion and penetration through holes 105, 106 greatly improve the diffusion of the composite absorbent core, and obtain a composite absorbent core that can conduct infiltration rapidly, and its absorption speed, plane absorption performance and U-shaped pressure absorption perf...

Abstract

The invention relates to a disposable absorption product capable of rapidly conducting infiltration, which comprises a liquid-permeable surface layer, a liquid-tight bottom layer and a composite absorption core body, wherein the composite absorption core body comprises a first expanded paper layer, a first super absorbent resin layer, a fluffy non-woven fabric layer, a second super absorbent resin layer and a second expanded paper layer from top to bottom. The disposable absorption product is formed by sequentially stacking and connecting all the layers and structurally characterized in that (1) the fluffy non-woven fabric layer is cut into a plurality of fluffy non-woven fabric strips arranged in the width direction of the fluffy non-woven fabric layer in the width direction of the fluffy non-woven fabric layer; and (2) certain stretching force is applied to the two longitudinal ends of each fluffy non-woven fabric strip, the breadth ratio of each fluffy non-woven fabric strip subjected to stretching deformation is 60%-80%, the transverse width of the fluffy non-woven fabric strip is made to be synchronously narrowed, flow guide permeation through holes with long slits or long grooves are formed between the stretched fluffy non-woven fabric strips, and after the composite absorption core body absorbs the liquid in a saturated manner, the composite absorption core body is folded at the crotch position to form a fit concave shape.

Description

technical field [0001] The invention belongs to the field of absorbent products, in particular to a disposable absorbent product that conducts infiltration rapidly. Background technique [0002] The invention relates to a production process for modifying the production process of the composite core body so that the core body has a diversion effect. At the present stage, the absorbent core body of sanitary products in the domestic market is mainly composed of five-layer composite core bodies, and the wood pulp polymer core body (traditional Core) has big problems in the strength and dryness of the core, but the composite core is limited by the distribution of polymers and the conductivity of the material itself, and the conduction of liquids cannot make the absorbent core rely only on the material itself and the liquid permeability of the polymer itself. The body is fully utilized, and the low utilization rate of the absorbent core is a major disadvantage of the composite cor...
