Description
Technical field
This utility model is related to a kind of fastener member, particularly relates to be used for the bullet in combination with ring in a kind of machanical fastener
Property fastener member.
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 that have end-boss in a substrate
Mushroom-shaped or into J-type hook be also surface fastener, another part is the ring with ring-type functional layer.By surface fastener
When part and ring are pressed, because being embedded in ring for surface fastener mutually winds with ring, so that the fastening for obtaining
Part can combine closely, difficult for drop-off.When suitable peeling force applies thereon, surface fastener and ring can separate again.
Separated by combination between the two, it is possible to achieve use repeatedly.
At present it prepares material and is typically thermoplastic, such as non-elastic material such as polypropylene, polyethylene, polyamide.
When surface fastener prepared by these materials is used for disposable sanitary articles field, such as diaper, then there are many defects.Example
Such as, after surface fastener prepared by these materials is combined with ring, then when tearing, ear-piercing sound can be sent, wakes what is slept soundly up
Baby；Simultaneously because the plastic sense of these materials is heavier, during with contact human skin, discomfort can be brought to user, sternly
Even can cause erythema during weight.
Utility model content
The purpose of this utility model is to provide a kind of for disposable sanitary articles（Such as diaper）Upper and ring knot
The hasp part of conjunction.The hasp part, on the one hand with the suitable intensity needed for being combined with ring and being peeled off；On the other hand
When the fastener member is torn after being combined with ring, ear-piercing sound will not be sent, at the same it is gentle with human contact, user will not be given
Bring discomfort.
For achieving the above object, solution of the present utility model is：
A kind of hasp part, comprising raised on backing and backing, wherein described projection is comprising bar portion and positioned at bar portion
The cap on top, described cap has at least one over-hang part extended laterally from described bar portion, described over-hang part bag
Containing elastomer, described over-hang part is beyond 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 raised height is 0.1 to 0.8mm.
Density of the described projection on the backing is 50 to 1000/cm2.
The backing thickness is 30 to 300 μm.
Using such scheme, the comfortable feature of elastomer soft-touch is made full use of, elastomer is applied to into hasp
Cap so that when the hasp part of preparation is torn after being combined with ring, will not send harsh noise, so as to will not wake up and
Scaring baby, while hasp cap has at least one over-hang part, and over-hang part exceeds bar portion certain length, is effectively ensured
Hasp can be combined firmly with ring, be difficult to disengage during use.

Specific embodiment
Embodiment of the present utility model is explained below in conjunction with accompanying drawing：
As shown in figure 1, this utility model discloses a kind of hasp part, can be used to mutually be tied with ring in machanical fastener
The surface fastener of conjunction.The fastener member includes on backing 1 and backing raised 2, raised 2 comprising bar portion 3 and positioned at the top of bar portion 3
Cap 4, described cap 4 has at least one over-hang part 5 laterally stretched out from described bar portion 3, and over-hang part 5 includes elasticity
Body 13.
In practice when hasp and ring depart from, harsh noise can be sent, while having during with human contact
Discomfort, or even friction generation erythema.This is to need improvement badly to disposable sanitary articles, especially diaper application
's.Therefore this defect can just be overcome using elastomer 13.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 have effect；
And too high accounting, then surface fastener will be caused to rupture or large deformation so that cannot effectively buckle with ring and separate.Together
When, the hardness of elastomer 13 is 20A-90A, and too low then because surface is too soft, ring easily departs from from projection, it is impossible to form enough
Tensile strength；Too high, the comfort of elastomer 13 and quietness when departing from ring will decline to a great extent.
Raised 2 density on backing 1 are too low, then when fastener member is contacted with ring, winding of the ring with raised 2 is inadequate, it is impossible to
Enough tensile strength is formed, when being applied on disposable sanitary articles, it may occur that depart from.Simultaneously too low density meeting
Sense of touch is set to be deteriorated.And density is too high, then when being applied on disposable sanitary articles, can cause that peel strength is excessive, stripping is got up
Difficultly.In this utility model, raised 2 density on the backing 1 that have selected preferentially are 50 to 1000/cm2.Nothing
The ring that cloth is made is spun, the thickness of wherein circular layer is generally less than 1mm.The height h of projection 2 of fastener member with matching is too low then
Cannot be combined with circular layer, too high then fastener member activity space is excessive, be equally easy to depart from from ring.The institute in this utility model
The height h of the projection 2 stated is 0.1-0.8mm.When ring is combined with fastener member, if the over-hang part 5 of cap 4 is beyond bar portion 3
Not enough, then ring is easily slipped length from bar end, affects shear strength.And exceed excessive, then raised 2 it is difficult to pass through ring, ring
Part is few with raised 2 twining amount, it is impossible to form enough tensile strength, and the over-hang part 5 of cap described in the utility model 4 exceeds bar
The length in portion 3 is between 0.02 to 0.4mm.Backing 1 directly affects the performance of fastener member as raised 2 supporting layer.Backing 1
Thickness d is excessive, then whole fastener member seems very hard, lacks sense of touch.Backing 1 is excessively thin, then cannot provide what projection 2 needed thereon
Intensity, raised 2 cannot proper alignment, the equally engagement of impact fastener member and ring.The thickness d of backing 1 described in this utility model
For 30 to 300 μm.
Noise Testing
Instrument：Psophometer model DT-815 Shenzhen Huashengchang Machinary Industry Co., Ltd
