Abstract
The invention discloses a kind of hasp part and production method thereof, this fastener member comprises on backing and backing protruding, wherein said projection comprises bar portion and is positioned at the cap on top, bar portion, described cap has at least one over-hang part laterally stretched out from described bar portion, described over-hang part comprises a kind of elastomer, the feature of the soft comfortable of elastomer can be utilized, make the fastener member of preparation for disposable sanitary articles, such as diaper, when using with ring collocation, under same peel strength, the noise sent is little and because soft skin-friendly is good.
Description
Technical field
The present invention relates to a kind of fastener member and production method thereof, particularly relate in a kind of machanical fastener for ring phase
In conjunction with hasp part and production method.
Background technology
Machanical fastener is known in the art, it is also possible to be called " hook and ring " securing member (" hook and loop "
Fasterners).Machanical fastener is made up of separable two parts, and a portion is to have end-boss in a substrate
Mushroom-shaped or become J-type hook be also surface fastener, another part is the ring with ring-type functional layer.By surface fastener
When part and ring pressing, owing to being embedded in ring of surface fastener and ring are mutually wound around, so that the fastening obtained
Part can be combined closely, difficult drop-off.When suitable peeling force applies on it, surface fastener and ring can be separated again.
Separated by combination between the two, it is possible to achieve use repeatedly.
At present it is prepared material and is typically thermoplastic, the non-elastic material such as such as polypropylene, polyethylene, polyamide.
The surface fastener prepared when these materials, for disposable sanitary articles field, during such as diaper, then has many defects.Example
As, after the surface fastener prepared when these materials is combined with ring, then when tearing, ear-piercing sound can be sent, wake up and sleep soundly
Baby；Simultaneously because the plastic sense of these materials is heavier, during with contact human skin, discomfort can be brought to user, sternly
Erythema even can be caused during weight.
Summary of the invention
It is an object of the invention to provide what one was above combined with ring for disposable sanitary articles (such as diaper)
Hasp part and production method thereof.This hasp part, on the one hand has the applicable intensity needed for being combined with ring and peel off；
On the other hand, when this fastener member is torn after being combined with ring, ear-piercing sound will not be sent, simultaneously gentle with human contact, will not
Discomfort is brought to user.
For achieving the above object, the solution of the present invention is:
A kind of hasp part, comprises on backing and backing protruding, it is characterised in that: described projection comprises bar portion and is positioned at bar
The cap on top, portion, described cap has at least one over-hang part extended laterally from described bar portion, described over-hang part
Comprising elastomer, described over-hang part exceeds bar portion 0.02 to 0.4mm.
Described elastomer is including but not limited to polyurethane elastomer, styrenic elastomer, polyolefin elastomer, poly-
One or more in esters thermoplastic elastomer (TPE).
Described cap is ailhead shape, umbrella shape, dish type or pyramid.
Described protruding height is 0.1 to 0.8mm.
Described projection density on described backing is 50 to 1000/cm2。
Described backing thickness is 30 to 300 μm.
The production method of a kind of hasp, concrete grammar is as follows: elastomeric material and inelastic thermoplastic's material are divided
Not melted in surface layer extruder and bottom extruder, then mix at die head, forming surface is elastomer, and bottom is non-ballistic
The sheet material of gonosome, eventually passes forming processes and forms the hasp that over-hang part comprises elastomer.
Use such scheme, make full use of the comfortable feature of elastomer soft-touch, elastomer is applied to hasp
Cap so that when the hasp part of preparation is torn after being combined with ring, harsh noise will not be sent, from without waking up and
Scaring baby, hasp cap has at least one over-hang part simultaneously, and over-hang part is beyond bar portion certain length, is effectively ensured
Hasp can firmly combine with ring, is difficult to disengage during use.

Detailed description of the invention
Below in conjunction with accompanying drawing explanation embodiments of the present invention:
As it is shown in figure 1, present invention is disclosed a kind of hasp part, can be used for the surface combined in machanical fastener with ring
Fastener member.This fastener member comprises projection 2 on backing 1 and backing, and protruding 2 comprise bar portion 3 and are positioned at the cap 4 on top, bar portion 3, institute
The cap 4 stated has at least one over-hang part 5 laterally stretched out from described bar portion 3, and over-hang part 5 comprises elastomer 13.
In practice when hasp departs from ring, harsh noise can be sent, have time simultaneously with human contact
Discomfort, even friction produce erythema.This is to disposable sanitary articles, especially diaper application, is to need improvement badly
's.Therefore elastomer 13 is used just can to overcome this defect.Elastomer 13 is soft, thus can be prevented effectively from ear-piercing noise and with
Discomfort during human contact.Elastomer 13 can include polyurethane elastomer, styrenic elastomer, polyolefin elastic
Body, polyester-type thermoplastic elastomer etc..The proportion of elastomer is 5% to 70%.Too low accounting, elastomer 13 does not has effect；
And too high accounting, then will cause surface fastener fracture or large deformation so that cannot effectively buckle with ring and separate.With
Time, the hardness of elastomer 13 is 20A-90A, and the lowest then because surface is too soft, ring easily departs from from projection, it is impossible to formed enough
Tensile strength；Too high, the comfort of elastomer 13 and quietness when departing from ring will decline to a great extent.
Protruding 2 density on backing 1 are too low, then, when fastener member contacts with ring, ring is inadequate with the winding of protruding 2, it is impossible to
Form enough tensile strength, when being applied on disposable sanitary articles, it may occur that depart from.The most too low density meeting
Sense of touch is made to be deteriorated.And density is too high, then when being applied on disposable sanitary articles, peel strength can be caused excessive, stripping is got up
Difficultly.In the present invention, protruding 2 density on described backing 1 that have selected preferentially are 50 to 1000/cm2.Non-woven fabrics
The ring made, wherein the thickness of circular layer is generally less than 1mm.H is too low then cannot for projection 2 height of fastener member with matching
Being combined with circular layer, too high then fastener member activity space is excessive, is equally easy to from ring depart from.Projection described in the present invention
The height h of 2 is 0.1-0.8mm.When ring is combined with fastener member, if the over-hang part of cap 45 is inadequate beyond the length in bar portion 3,
Then ring easily slips from bar end, affects shear strength.And beyond excessive, then protruding 2 are difficult to pass through ring, ring and protruding 2
Twining amount is few, it is impossible to form enough tensile strength, the over-hang part of cap 4 of the present invention 5 beyond bar portion 3 length between
0.02 to 0.4mm.Backing 1, as the supporting layer of protruding 2, directly affects the performance of fastener member.The thickness d of backing 1 is excessive, the most whole
Individual fastener member seems very hard, lacks sense of touch.Backing 1 is the thinnest, then cannot provide protruding 2 intensity needed thereon, and protruding 2 cannot
Proper alignment, affects the joint of fastener member and ring equally.Heretofore described backing 1 thickness d is 30 to 300 μm.
Noise Testing
Instrument: psophometer model DT-815 Shenzhen Huashengchang Machinary Industry Co., Ltd
Material: fastener member, ring (model L6511, Xiamen and clean bonded fabric product company limited)
Testing procedure: fastener member is cut to 35mm × 15mm, then the ring with same model is combined.When this hasp part
Noise decibel value is surveyed with psophometer in detection at its 50mm when separating with ring.
