Problems solved by technology

[0005] The purpose of the embodiments of the present invention is to provide an absorbent core for diapers, which improves the absorbent core in the prior art, can effectively solve the problem of lumping and faults in the fluff pulp core, and at the same time improve the ultra-thin composite core. Liquid diffusibility and core utilization, the obtained diapers achieve a better balance in terms of "thinness", "overall absorbency" and "comfort in each part", so as to obtain an ultra-thin diaper with instant suction function Diapers

Embodiment 1

[0039] Such as figure 1 As shown in FIG. 1 , a schematic cross-sectional view of the main body of the absorbent core of a diaper provided by an embodiment of the present invention is shown. The main body comprises an upper covering layer 1 , a first polymer absorbing layer 2 , a fluffy cotton layer 3 , a second polymer absorbing layer 4 and a lower covering layer 5 stacked sequentially from top to bottom. The upper cladding layer 1 is 13gsm wet strength paper, and the lower cladding layer 5 is 30gsm direct lay spunlace non-woven fabric. The fluffy cotton is mixed with 4-denier ES fibers and 6-denier PET fibers and bonded by hot air to obtain a fluffy nonwoven fabric of 35 gsm.

Embodiment 2

[0041] Such as figure 2 As shown, a schematic cross-sectional view of the absorbent core of a diaper provided by an embodiment of the present invention is shown. The absorbent core can be seen as figure 1 The two side ends 7, 8 of the main body in the body are bent to the upper covering layer 1, and after the bending, the two side ends 7, 8 face each other at intervals, so that grooves 6 are formed on the upper surface of the absorbent core. The left side of the groove 6 is a left bending part 9 , and the right side is a right bending part 10 . The groove 6 is arranged in the middle of the upper surface of the absorbent core, so that the left bending part 9 and the right bending part 10 are symmetrical to the groove 6 . The groove 6 is linear in longitudinal direction, rectangular in cross section and 15mm in width.

Embodiment 3

[0043] Such as image 3 As shown in FIG. 1 , it shows a schematic diagram of the production line of the method for preparing the absorbent core of a diaper provided by an embodiment of the present invention. The pipeline includes the following steps:

[0044] S1. Fluffy cotton unwinding process: After the finished fluffy cotton is unrolled 11, it is continuously conveyed to the direction of the first particle hopper 12 and the second particle hopper 13 of the second polymer absorbent material through an auxiliary device; wherein the first particle hopper 12 Contain superabsorbent resin (SAP) particles of different size gradations in the second particle hopper 13;

[0045] S2. The second polymer absorbent material blanking process: the hoppers 12 and 13 evenly spread the second polymer absorbent material graded in different sizes on the fluffy cotton transported here through the S1 process;

[0046] S3. Lamination process of the lower cladding layer: Unwind the finished roll ...

Abstract

The embodiment of the invention discloses a paper diaper absorption core and a preparation method thereof. The absorption core comprises a body, and the body comprises an upper cladding layer, a firstpolymer absorption layer, a fluffy cotton layer, a second polymer absorption layer and a lower cladding layer which are sequentially overlaid from top to bottom. The absorption core is implemented bybending the two side ends of the body towards the cladding layers on the body, the intervals between the two side ends after bending are opposite, so that a groove is formed in the upper surface of the absorption core. The absorption core is improved based on an absorption core in the prior art, the problem of lump formation and fault of a fluff pulp core can be effectively solved, and the liquiddiffusion property of an ultra-thin composite core and the core utilization rate are improved.

Description

technical field [0001] The invention relates to the technical field of sanitary care products for infants and young children, in particular to a diaper absorbent core and a preparation method thereof. Background technique [0002] Diapers are disposable sanitary products for infants and young children composed of non-woven fabrics and absorbent cores, and are mainly used to absorb urine from infants and young children. The part of diapers that absorbs urine is the absorbent core, which is one of the main components of disposable sanitary products such as diapers, sanitary napkins, and panty liners. Diaper cores in different regions of the world have different designs, mainly divided into fluff pulp cores and composite cores. [0003] The fluff pulp core is mainly composed of superabsorbent resin (SAP) particles dispersed in fluff pulp fibers. This kind of core is widely used in European and American countries. The presence of fluff pulp in this core can provide a temporary ...
