Description

A kind of moisture absorption body of paper diaper

Technical field

The utility model belongs to the technical field of paper diaper, and in particular, to the moisture absorption core in a kind of paper diaper.

Background technique

The core of paper diaper is core, it determines the uptake of paper diaper, infiltration rate, water lock ability, comfortable Property, and whether tomography, therefore core quality directly decision paper diaper performance superiority and inferiority whether；Domestic ultra-thin baby's paper at present The absorber of urine pants, more traditional moisture absorber makees surface layer using extruding dust-free paper or hydrophilic non-woven, conventional resins are made For water absorption layer；The extruding dust-free paper characteristic: because being free of chemical adhesive, product is fluffy, good hygroscopicity, but intensity difference, wood pulp Fiber easily falls (when being processed into urine pants absorber and production urine pants, easily broken and dust is big), and single-point water filling absorbs rounded diffusion；This Sample absorber is plane average diffusion when absorbing water, and the width that will cause moisture absorption body in this way limits absorber suction Water efficiency.

Utility model content

The purpose of the utility model is to provide a kind of moisture absorption bodies of paper diaper, change to the moisture absorption body structure, To make to absorb, moisture is more efficient, and product is dryer and comfortableer.

The utility model adopts the following technical solutions:

A kind of moisture absorption body of paper diaper, it is characterised in that: including be sequentially overlapped surface layer, water absorption layer, bottom, it is described Surface layer be wood pulp composite spun-laced fabric.

One preferred technique feature: the water absorption layer includes bilevel hydroscopic high-molecular resin, is located at two layers of high score The bulk hot-wind nonwoven cloth of height between sub- water-absorbing resin.

One preferred technique feature: the bulk hot-wind nonwoven cloth base weight of height is 40-55gsm, with a thickness of 5-8mm, fiber Thickness is 2.0-3.5dtex.

One preferred technique feature: the bottom is hot wind

One preferred technique feature: its base weight of the hot-wind nonwoven cloth is 20-30gsm, fiber thickness 1.5- 2.0dtex。

Compared with prior art, the utility model has the beneficial effects that 1, use wood pulp composite spun-laced fabric as surface layer, due to Wood pulp composite spun-laced fabric has bar shaped capillary, which extends to absorber length direction, in this way to the infiltration of moisture It is to permeate along its length, i.e., is permeated along absorber rear and front end direction, relatively traditional use extruding dust-free paper penetration mode For, the utility model can quickly be spread the urine absorption of baby's discharge and to both ends, the service efficiency of absorber is improved, Surface is dryer and comfortableer；Baby's skin and urine time of contact are reduced, the risk of the red hip of baby is reduced；Also it can effectively avoid because absorbing What body local absorption generated rise stick together it is uncomfortable to baby bring.

Detailed description of the invention

Fig. 1 is the overall structure diagram of the utility model；

Specific embodiment

Below by way of specific embodiment, the utility model will be further described.

Referring to Fig.1, the moisture absorption body of a kind of paper diaper, is also Water-absorption core body, positioned at the internal layer of paper diaper；The moisture content is inhaled Acceptor includes the surface layer being sequentially overlapped, water absorption layer, bottom, and the surface layer is wood pulp composite spun-laced fabric；The water absorption layer packet Include bilevel antibacterial deodourizing hydroscopic high-molecular resin, the bulk hot wind nonwoven of height between two layers of hydroscopic high-molecular resin Cloth；The bottom is hot-wind nonwoven cloth.

Above-mentioned its production technology of wood pulp composite spun-laced fabric: wood pulp spunlace production technology, which is detailed in Zhang Zhijuan and is published in, " to be produced Industry textile " " production technology and application of wood pulp composite spun-laced fabric ", article number: 1004-7093 (2008) 12-0028- 04, characteristic: it is dustless, without fibre shedding in use process, Soft flocks are not generated, fiber networking is uniform, and fiber has excellent Vertically and horizontally pulling force；Especially its internal fiber combs in one direction at straight lapped fibers.

Since the wood pulp composite spun-laced fabric has bar shaped capillary, in this way in the infiltration of water also along bar shaped capillary direction Infiltration is bar shaped infiltration, therefore the wood pulp composite spun-laced fabric can be taken to replace now in the upper surface cloth for being fabricated to urine pants absorber Some non-woven fabrics, and the bar shaped capillary extending direction of the wood pulp composite spun-laced fabric is consistent with moisture absorption body length, in this way The diffusion of moisture content is spread in bar shaped, so that urine can be permeated along absorber rear and front end direction, is also prevented from urine and does not have also Having arrival reproduction portion rear end, just from the both sides of width, exudation comes；Efficiently solve the product strength of the existing non-woven fabrics used Difference, wood pulp cellulose easily falls and diaper service efficiency problem caused by the rounded diffusion of single-point moisture content.The baby's paper worked it out in this way Diaper product is thinner, more soft, flexible, dryer and comfortableer；2, equipment throughput rate is improved, the powder in process of producing product is reduced Dirt.

Above-mentioned hydroscopic high-molecular resin is the antibacterial and deodouring hydroscopic high-molecular resin of Yixing Dansen Technology Co., Ltd. (SAP)；It replaces traditional hydroscopic high-molecular resin (SAP) that urine ammonia concentration is effectively reduced to reaching antibacterial taste removal, drops The risk of the low red hip of baby.

It is thinner, flexible, dryer and comfortableer using surface while more suitable such as product in order to which product quality more preferably optimizes For producing, it is as defined below to make product:

The above-mentioned bulk hot-wind nonwoven cloth base weight of height is preferably 40-55gsm, with a thickness of 5-8mm, fiber thickness 2.0- 3.5dtex。

Its base weight of above-mentioned hot-wind nonwoven cloth is preferably 20-30gsm, fiber thickness 1.5-2.0dtex.

It is above-mentioned it is at all levels be to be bonded by wet strong structure glue, glue dosage is in 3-7gsm.

The above, the only preferred embodiment of the utility model, therefore the utility model implementation cannot be limited with this Range should still belong to this that is, according to equivalent changes and modifications made by present utility model application the scope of the patents and description In the range of utility model patent is covered.
