Description
Background technology
Conventional open diaper and incontinence product is produced by side-closed formula in recent years while still widely using
Product are substituted, and these products are commonly known as training pants and pull-up diaper, and this is due to that they make use of more according to often
The fact that the base design that rule underwear is modeled.Therefore, they generally include to use side seams by front waist cut-parts and low back
Portion's cut-parts link to form waist opening and leg opening.
Due to the property of the material for forming waist cut-parts, replace adhesive seam that side is made usually using heat fusing
Seam.Hot seam be more desirably because they due to corresponding front waist cut-parts and the fiber of rear waist cut-parts and/or its
The fusing and melting of his material and stronger combination can be formed.In order to form the side seams of such combination, employ some
Technology.A kind of to make that ultrasonic wave combines and another kind is conventional by thermal roller, it is usually using the roller of convex pattern and right
The smooth anvil roller or the roller of matched patterns answered, wherein the combination design on each roller matches each other.
It is important to produce good side seams and combine for the overall integrity of product.Without good side joint
In the case that seam combines, front waist cut-parts and rear waist cut-parts prematurely may be layered each other, cause product portion during use
Divide or be totally released, so as to cause many consequences undesirably.
Fortunately, this problem will not frequently encounter, because commonly, in the corresponding towards body of waist cut-parts
Surface and towards in both garment surfaces, the waist cut-parts material of front waist cut-parts and rear waist cut-parts is by identical material system
Into.
Unfortunately, as the progress of product design and the sustainable growth of the market demand, goods producer have increasing need for
Increasing function is incorporated to promote production marketing.The attribute especially needed is pliability.For many years, many pull-ups
Product forms fiber using conventional polyacrylic polymer, and these fibers, which enter, forms front waist cut-parts and rear waist cut-parts
The fibrous nonwoven web towards garment side and towards bodyside.
For waist cut-parts in itself, common design is that (one is used for using two outer layers of fibrous nonwoven web
Garment side, and one is used for towards bodyside), wherein one layer of elastomeric material be clipped in fiber non-woven net materials outer layer it
Between, and knife is linked to each outer layer with bonding mode.Elastic layer can be strand material, such as multiple to extend laterally and vertically
Elastic strands spaced apart.Alternately, elastic layer can be laminated between two outer layers of fiber non-woven net materials
Layers of elastomeric film or elastic mesh material layer.
In the case of such design, common formation technology is the outside material layer towards clothes (is formed waistband
Above the uppermost margin of elastomeric material) higher than the internal material layer towards body, it also extends into the elastic material to form waistband
Above the uppermost margin of material.This extra outside Waistband material is inwardly folding on body-facing layer, and then to
Under be folded on the topmost top edge of absorbent cores.This is done to protect a wearer from the unfinished of absorbent cores
Or the influence of the top edge otherwise exposed.Alternately, two layers, i.e. internal layer and outer layer is in the most upper of elastomeric material
Extend above portion edge, and be then inwardly folding on the top edge of absorbent cores, equally to protect a wearer from
The influence of the top edge of absorbent cores.In another embodiment, including all three parts (outer layer, elastic layer and internal layer)
A part for waistband inwardly product bodyside fold.Therefore, a part for outer layer turns into again is subjected to melt binding
The internal layer of side seams.In all previous embodiments, when internal layer and outer layer are by identical polymer or compatible polymer system
Cheng Shi, the side seams for forming the heat fusion with enough side seams intensity are not a problem.
However, in order to manufacture product more desirably, a solution is to carry out shape using polymer such as polyethylene
Into with polyethylene outer surface or the uniform fiber or bicomponent fibre of sheath and polyester or polypropylene inside or core.With poly- third
Alkene is compared, and polyethylene is considered to have more preferable feel and more perception pliabilitys.Attempt however, working as by polyethylene and poly- third
During alkene melt binding, it is possible that problem.Due to the incompatibility of polymer, form firm side joint and be seamed into problem, because
It can not be combined together for such polymer by standard construction technology using melt binding (heat and pressure).Will because working as
When outer layer is folded on the inside of product to cover the top edge of absorbent cores, outer layer is dispersed between internal layer.Therefore, hair is worked as
When raw melted by heating is combined to form side seams, the layer of different polymer can not be combined fully, and therefore be opened during use
Begin to be layered, so as to cause it is the unacceptable product of inferior quality from the point of view of consumer point.Therefore, it is necessary to a kind of design of replacement,
It allows to use incompatible polymers, while still forms firm side seams and the more soft product of sensigenous.

When 34, the material for forming the material of the garment side of waist cut-parts and the bodyside of formation waist cut-parts is possible incompatible.Such as fruit shape
Into the material of the outside of waist cut-parts or garment side and the inner side or lining side or the material towards bodyside that form waist cut-parts
Can not melt binding well, then when exterior material to interior folding to cover the top edge of absorbing structure when, the material of outer layer
By between the layer of incompatible inside material, and therefore the melt binding of the layer in side seams will likely be by shadow
Ring.Therefore, when outer layer is inwardly folding on the top of absorbing structure to cover its top edge with conventional manufacturing process, from
From the perspective of melt binding, the material of outer layer and internal layer for forming waist cut-parts must be compatible with each other.
In the case where current folding process and resulting product and side seams design, internal material and exterior material
It is whether compatible unimportant, the mode for being folded/shaping due to the design, it is not necessary to which cladding material is subjected to melt binding to be formed
Side seams interior section.Therefore, these layers and problem is not turned into the problem of material whether compatible with each other.
It should be appreciated that the present invention relates to side seams 34, it is fusion together by using heat and pressure, the heat and pressure
Such as by using such as by the generation of the combination technology of thermal roller and ultrasonic wave bonding apparatus.Above and below formation side seams 34
Wen Zhong, these melt binding technologies are referred to as combining or merged.This should be differentiated with forming side seams 34 using adhesive, to the greatest extent
Pipe can use supplement of the adhesive as foregoing combined/fused technology.It is, for example, possible to use protective layer 68 is attached by adhesive
To absorbing structure 38 towards body surface, and some in this adhesive may be alternatively located in the area of side seams 34.It is in addition, viscous
Mixture will likely be used at least certain part towards body surface of waist cut-parts clothes layer 60,64 being attached to corresponding waist
Portion's cut-parts backing layer 62,66 towards garment surface.
Fig. 3 A, Fig. 5 and Fig. 6 are turned to, when forming side seams 34, front waist cut-parts backing layer (62) and rear waist cut-parts lining
Nexine (64) and front waist cut-parts protective layer (68) and rear waist cut-parts protective layer (70) must be compatible with each other for suture
