Abstract

The present invention relates to a kind of water absorbing properties preferably with the amenities of foldable layer, the amenities is cream pad or diaper or sanitary napkin etc., the amenities includes hydrophilic layer, absorbed layer and the waterproof layer of successively lamination setting, the two sides of hydrophilic layer and/or waterproof layer are equipped with a pair of of foldable layer, or, being equipped with a foldable layer in the center of hydrophilic layer and/or waterproof layer；The absorbed layer is after drawing a certain amount of water, foldable layer is strutted outward, to provide enough expansion spaces to the hydroscopic high-molecular resin SAP in absorbed layer, so that SAP is sufficiently absorbed water and can finally reach saturation state, and then take full advantage of SAP, or in the case where absorbing equivalent amount of water, SAP can be used less.After tested, compared with the existing technology, under conditions of the SAP weight that the cream pad of the application uses is less than the prior art 10%, the water absorption of the application cream pad improves 15% to the water absorbing capacity of the application cream pad.

Description

The preferable cream pad of water absorbing properties

Technical field

The present invention relates to the technical field of amenities, specifically a kind of includes cream pad or diaper or sanitary napkin etc. Amenities.

Background technique

The cream pad amenities such as diaper or sanitary napkin of the breast feeding women of the prior art, including successively lamination point Hydrophilic layer, absorbed layer and the water repellent layer (also referred to as waterproof layer) of cloth；The bonding of the surrounding of hydrophilic layer and water repellent layer, absorbed layer is contained in Between hydrophilic layer and water repellent layer；Absorbed layer mainly includes the hydroscopic high-molecular resin (abbreviation SAP) by non-woven wraps, insufficient Place is: the space between hydrophilic layer and waterproof layer is smaller, so that the space expanded after absorbing water to the SAP in absorbed layer is not Foot, causes SAP to be unable to fully absorb water, and makes it far from reaching water suction saturation state, and then producer can only add SAP, do big production Product size meets the requirement of water absorption, forms the waste of relevant raw materials, SAP, also forms a level pressure to environmental protection Power.

The water imbibition for how improving the amenities such as cream pad as far as possible in the case where identical SAP dosage, is that this field is wanted The technical issues of solution.

Summary of the invention

Technical problem to be solved by the invention is to provide a kind of structures simply, the cream of SAP soaking effect can be substantially improved Pad.

To solve the above-mentioned problems, the present invention provides a kind of water absorbing properties preferably, the amenities with foldable layer, including Successively hydrophilic layer, absorbed layer and the waterproof layer of lamination setting, hydrophilic layer and/or waterproof layer are equipped at least one foldable layer.Institute State foldable layer be turn down outward it is primary and molding, can also fold inward it is primary.

Preferable scheme is that the two sides of hydrophilic layer and/or waterproof layer are equipped with a pair of of foldable layer；It is further preferred that this is right Foldable layer is symmetrical adjacent to the both sides of the edge of the hydrophilic layer.Or, foldable layer is arranged in hydrophilic layer and/or waterproof layer Centre.

Further preferred scheme is that the both ends of the foldable layer and the hydrophilic layer and waterproof layer edge pass through heat Pressure roller welding or ultrasonic bonding are connected.

The amenities is cream pad or diaper or sanitary napkin.

It is another Preferable scheme is that, the two sides of the hydrophilic layer are equipped with a pair of of foldable layer, and the center of waterproof layer is equipped with a folding Lamination.It is further preferred that this is symmetrical adjacent to the both sides of the edge of the hydrophilic layer to foldable layer.

On the basis of above-mentioned each scheme, Preferable scheme is that, one on the foldable layer of the hydrophilic layer and/or waterproof layer Point or the multiple spot to distribute alternately bonding or ultrasonic bonding are on waterproof layer, so that foldable layer is close to product side, to avoid production Product are whole excessively loose.

Technical effect of the invention: (1) in the preferable amenities of water absorbing properties of the invention, the absorbed layer is being drawn After a certain amount of water, foldable layer is strutted outward, and then supportted the space between the hydrophilic layer and waterproof layer big, in absorbed layer Hydroscopic high-molecular resin SAP provide enough expansion spaces, so that SAP is sufficiently absorbed water and can finally reach saturation shape State, and then SAP is taken full advantage of, or in the case where absorbing equivalent amount of water, SAP can be used less.After tested, the water suction of the application cream pad Ability compared with the existing technology, the application cream pad use SAP weight be less than the prior art 10% under conditions of, the application The water absorption of cream pad improves 15-20%.(2) in the present invention, foldable layer is set on waterproof layer, when can product be used SAP expands outward, avoids it and expands inwardly and directly act on human skin, influences comfort.(3) of the invention In, foldable layer is to turn down outward primary and molding, and outward when strutting foldable layer, the foldable layer turned down outward is opposite for SAP water suction Be easier to strut in the foldable layer of fold inward, be not easily susceptible to human body wearing amenities when foldable layer and skin generate pressure and Limitation foldable layer struts outward.
