Description

High osmosis 3D surface layer with embossing

Technical field

The utility model relates to absorbent device technical fields, in particular to have the high osmosis 3D surface layer of embossing.

Background technique

Infant and other people that can't take care of oneself are often required to wear absorbent device, such as diaper.The function of absorbent device It can be that it can accommodate excreta, and keep apart the body of these excretas and wearer and clothes and bedding.Absorbent device Usually can simultaneously it be accommodated by fluidity surface layer, opaque liquid bottom and the absorption between permeable top layer and opaque liquid bottom The absorbent cores of liquid form.

The surface material of disposable absorbent article can be divided by the net-forming process of material: hydrophily spun-bonded non-woven fabrics, hydrophilic Property fabric hot rolled nonwoven fabrics, hydrophily hot-wind nonwoven cloth.It can be divided by aftertreatment technology: hydrophily plain weave non-woven fabrics, hydrophily punching Non-woven fabrics, embossing non-woven fabrics, 3D salient point non-woven fabrics.Usual surface material gets following purpose in disposable absorbent article: first, Surface material provides some fluid conveying performances, these performances include quick collection across the surface layer and are absorbed what wicking was received Fluid, and the fluid " rehumidifying " for preventing the absorbent cores from absorbing, that is to say, that as long as fluid is absorbed by the absorbent cores, It does not pass through above-mentioned surface layer and bleeds back leakage, to get the skin of wearer wet.In general, the surface for contacting skin is drier, Absorbing articles just make one to feel more comfortable.Second, the surface layer due to compliance, soft feel, it is dry and to wearing Person's skin is non-stimulated, to provide skin comfort.

The 3D protrusion surface layer disclosed in the prior art, is generally made of upper layer and lower layer non-woven fabrics, in the surrounding of protrusion Or 8 thermal bonding points or special hot embossing process are formed at 6 points, to realize the bonding of upper and lower level non-woven fabrics and to protrusion Fixation, and be not dispersed with water conservancy diversion hole the same approximation of thermal bonding point is circumferentially spaced about.Such as:
