Description
Technical field
When being weaved the present invention relates to a kind of injection molding zipper strap of new structure, the especially strap, in strap
Side centerline edge forms continuous, fixed intervals and aperture of the same size, thus improve injection molding zipper chain tooth and strap it
Between bond strength.
Background technology
There are thicker center line, injection material when slide fastener produces after hot melt in strap used in traditional injection moulding slide fastener, edge
Material injection zipper mould, clamps the thicker center line of cloth belt edge behind strap both sides, cooling in a mold, formed chain tooth with
The combination of strap.Since chain tooth material is plastic material, so such combination makes between injection molding zipper chain tooth and strap
Bond strength it is weaker always.Especially injection molding zipper is chiefly used in down coat, cold season, the occasion of special low temperature, modeling
Glue material is it is also possible to understand low temperature brittleness, so that risk of the injection molding zipper there are chain odontoptosis.
On 2 1st, 2006 China Intellectual Property Office disclose Japanese YKK Co., Ltd a Chinese invention patent (in
State's patent No.：200510084983.2 entitled " fastener stringer and its manufacturing method "), it is intended to it is strong to improve injection molding zipper
Degree, technical solution are：Warp thread exclusionary zone is formed in cloth belt edge (i.e. the side of center line), and its warp thread exclusionary zone
It is to dissolve and formed when strap dyes using the pre-set water-soluble yarn in region during ribbon, is excluded using the warp thread
Region, injected plastics material can penetrate strap when injection molding zipper produces so that chain tooth can be firmly installed on cloth band, and it is tied
Closing intensity can also get a promotion.Although strap forms warp thread exclusionary zone in this scheme, in the region, weft yarn is still
Exist with original condition mode, thus when injection molding zipper produces injected plastics material penetrate strap be it is difficult, it is insufficient, therefore
Promotion to chain tooth and strap bond strength is limited；Additionally due to the presence of strap marginal warp exclusionary zone, cloth band edge
Edge center line just reduces the part warp thread for playing fixation to it originally, and the position of center line, which is stablized, there is risk, this
Deviation will occur for positioning of the strap in zipper mould when sample injection molding zipper produces, and influence the normal life of injection molding zipper instead
Production.
In addition on January 5th, 2011, China Intellectual Property Office disclose an other patent of invention (China Patent No.：
200910057534.7, entitled " a kind of strap "), technical solution is：In the combination of strap and injection molding zipper chain tooth
By the setting of the structure organization to strap warp thread in the region of face, as shown in figure 4, warp thread a33, a35 are set to one on the other
The structure organization for cycling, intermediate warp thread a34 are set to the structure organization cycled on three times three；And warp thread a36, a38 and a37 then with
Warp thread a33, a35 and a34 are corresponding on the contrary, being set to the structure organization of next upper and Three Up Three Down Xun Huan.Such structure organization
Under the strap that is made into, due to the influence of warp tension effect, the intertwined point of weft yarn a21, a23 and warp thread a33, a35, a36, a38
It will be shifted over simultaneously tightly close to weft yarn a22, the intertwined point of similary weft yarn a24, a26 and warp thread a33, a35, a36, a38
It can be shifted over simultaneously tightly close to weft yarn a25；Simultaneously because the influence of weft tension effect, warp thread a33, a35 and weft yarn a21,
The intertwined point of a23, a24, a26 will shift and tightly close to warp thread a34, similary warp thread a36, a38 and weft yarn a21, a23,
The intertwined point of a24, a26 can also shift and tightly close to warp thread a37；So intertwined point be shifted over after just in warp thread a35, a36,
Aperture a4 is formed among weft yarn a23, a24.Every three latitudes are just formd while such ribbon between strap warp thread a35, a36
Yarn is the aperture a4 in a row at interval；Injected plastics material penetrates mutually in strap both sides when using the aperture slide fastener being produced,
So as to improve the combination power of injection molding zipper chain tooth and strap.This scheme is true using the setting of warp thread institutional framework and the tension of yarn
In fact aperture can be formed while ribbon, but due in strap in this scheme warp thread be arranged in order, strap weaves it
Afterwards, warp thread just no longer by ribbon when added tension affect, according to yarn always can to the principle of the movement of resistance minimum,
Warp thread a35, the a36 on so aperture both sides there is the trend moved to small hole center, and particularly strap is being subject to the feelings of external force
Under condition；And strap also has many production processes between the production of injection molding zipper is arrived after weaving, including sizing, around band, dyeing, baking
Dry, row's tooth etc., strap can be after multiple pendants such as idler wheel, pinch roller among each process, and bear repeatedly to tense, loosen
External force, the influence shunk through weft yarn during along with high-temperature dyeing, strap aperture both sides warp thread a35, a36 will be shifted over, to
Small hole center is drawn close, and the aperture formed during original ribbon is become smaller；Injected plastics material is in strap when so injection molding zipper produces
Both sides effectively penetrate mutually and there is uncertainty, so as to influence the combination power for improving injection molding zipper chain tooth and strap.
As the improvement to said program, as shown in figure 5, the patent No.：201410117840.6 patent name《A kind of note
Mould zipper cloth belt》Technical solution be：Set two groups of warp thread in the faying face region of the strap and injection molding zipper chain tooth, every group
Interior two warp thread form the insulating space on strap warp thread direction between two groups in a manner of every empty reed position；Two in every group
For warp thread separately and continuously to clamp the weft yarn of fixed quantity item number and be reversed, torsion every time is squeezed into sandwiched weft yarn
Weft yarn beam item, and the space between strap weft yarn beam item is formed, form aperture with the insulating space of warp thread direction.
The technical solution of the patent can actually be formed between two groups of warp thread in the faying face region of strap and chain tooth
The aperture of consecutive intervals, but since cloth belt edge has thicker upper center line 30A, lower center line 30B, positioned at cloth belt edge two
Side, it is necessary to up and down to just (in terms of strap section, referring to Fig. 3), it is impossible to have position deviation, when otherwise will influence follow-up row's tooth production
Positioning of the strap in Tooth arranging die, so as to influence the product quality of injection molding zipper.Therefore in strap and chain tooth faying face region
A certain number of warp thread, which are also needed to, between one group of warp thread b33, b34 and center line b30 of inside carrys out fixed center line, the warp thread number
If amount deficiency may cause center line up and down can not be to just, causing deviation；Quantity is enough, and it is right above and below center line to ensure
Just, but position or the size of the aperture b4 between above-mentioned two groups of warp thread can be influenced, it is possible to can exposed portion to strap and
Outside the faying face of chain tooth, zipper product quality and appearance are influenced, particularly for the injection molding zipper product compared with ting model；And or
If the interval that person reduces between above-mentioned two groups of warp thread can allow aperture to become smaller again, and the hole to become smaller is to the intensity of promotion injection molding zipper
