(2. fiber component)
It is illustrated for fiber component.In the component for constituting zipper, the component that can become fiber component is not limited,
It can be zipper strip, chain denture, core rope and reinforcing band etc..Pulling-on piece can also be constituted by fiber component.Alternatively, it is also possible to by lifting rope
Equal lanyards are mounted on zipper.Zipper strip generally has：The chain tooth mounting portion of the lateral margin of chain denture is installed；With its opposite side
The band main part sutured with the main part of article, can make zipper strip and carrying out tatting or knitting to fiber.As
The chain denture of threadiness, can enumerate monofilament being configured to coiled type, jagged continuous chain denture.Core rope is by along drawing
The lateral margin of the length direction of chain belt is incorporated into and the protrusion that is formed.By making chain tooth bite core rope so as to improving chain tooth
Installation strength.Core rope can be made of the knitting technology weave of core wire and the tubulose of covering core wire periphery.It is longitudinal from reducing for core wire
From the perspective of elongation, the line that do not twist preferably is closed up more to use.The breakage of zipper strip, reinforcing band can in order to prevent
Either upper end and lower end for being pasted onto zipper strip with the width direction along zipper strip or two sides, can be used plain weave
Reinforcing band made of equal tattings.It is effective that reinforcing band is pasted in the mode being clipped between the surface of zipper strip and the back side.
Fig. 5 shows the structural example of core rope 500.The radially arranged appropriate number of knitted yarn T around core wire 501
(the case where diagram be 4), knitted yarn T is bent into 8 fonts along the outer surface of core wire 501 in a circumferential direction, turned at it
Transfer part makes each needle loop L1、L2, make upper needle loop L1Successively it is wrapped in the next needle loop L2On, thus in core wire 501
Around construct the knitting technology weave of tubulose.Then, pass through the needle loop L of the knitting technology weave of tubulose1、L2With sinker loop l1、l2It can be with
Tighten core wire 501 securely towards central part.
Fiber component is since using polyethylene terephthalate (PET) resin as material, dyeability is excellent.But
It is that the injection moldability of chain tooth when tatting zipper strip becomes problem.In order to which chain tooth is injection moulded on zipper strip, zipper strip
Need twill.The nylon fiber that common polyester zipper strip uses several shrinking percentages high is as fastening line, via thermal finalization
Twill is consequently formed in dyeing process.But in the case where the zipper strip of whole polyester, since expansion and contraction is difficult difference occur, because
The straight band of not twill is formed after this thermal finalization dyeing.In the case where that can not form twill or the formation of twill is not filled
In the case where point, the engagement of generation core is bad when chain tooth is injection moulded, and yield rate is remarkably decreased.
The inventors discovered that retractility can be improved by the count of weft yarn when reducing tatting zipper strip, and
And it improves the row number of core rope and densification, reduces retractility and solve the problems, such as this.Generally, for zipper
Band manufactures, and in the heat-setting process after tatting, if sufficiently shrinking, in dyeing, band can slightly stretch in bath.This
Place, by improving the retractility of band, band becomes easy stretching, extension in dyeing, and on the other hand, core rope is being contaminated through densification
It becomes difficult to stretch when color, twill is consequently formed, be formed to injection molding band.Wherein, it can be achieved at the same time core engagement
The numberical range of the row number of the count and core rope of the band of both use intensities of undesirable elimination and band is relatively narrow.
It is considered that finding that the numberical range is also biggish technical contribution of the invention.
Specifically, it is preferable that the count of the weft yarn of zipper strip is set as 37~43 pieces/inch (2.54cm), by core rope
Row number be set as 24 rows/25.4mm or more.Alternatively, it is preferred that the count of the weft yarn of zipper strip is set as 37
~39 pieces/inch (2.54cm), the row number of core rope is set as 20 rows/25.4mm or more.Pass through the combination, energy
Core engagement when accessing chain tooth injection moldability is good and intensity also excellent zipper strip.It is further preferred that by zipper strip
The count of weft yarn is set as 38~42 pieces/inch (2.54cm), the row number of core rope is set as to 25 rows/
The count of the weft yarn of zipper strip is still more preferably set as 38~40 pieces/inch (2.54cm), by core by 25.4mm or more
The row number of rope is set as 25 rows/25.4mm or more.The row number of core rope is higher, twill more easy to form,
If but it is excessively high, core rope is hardened, flexibility reduces, and thus there may be the opening and closings of pull head to become heavy such problems, because
This preferably 30 or less, more preferable 27 or less.Herein, the row number of core rope refers to arranges in the transverse direction for constituting the knitted fabric of core rope
The quantity of the coil column of column.
For constituting the fiber number of the line of zipper strip, it is set as range used by usual zipper strip, such as can will be through
Yarn is set as 75~500dTex of fiber number, weft yarn is set as to 75~500dTex of fiber number, for typical, warp thread can be set as fiber number
100~400dTex, weft yarn is set as to 100~400dTex of fiber number.Any one of monofilament and multifilament, single line can be used in line
Can be made of monofilament, can also the multifilament made of the monofilament boundling by 2 or more constitute, and then can also be by more multifilament
It constitutes.For example, by 2, line that multifilament made of monofilament boundling by 50 5dTex is constituted is 500dTex 1
Line.Although also depending on the loom used, weft yarn is generally made of 2 multifilament.
(3. injection-molded parts)
Then, it is illustrated for injection-molded parts.In the component for constituting zipper, injection-molded parts can be become
Component does not limit, and for pull head, chain denture, upper stop member, lower stop member and can open from inlay etc..Pull head is for for chain denture
Across with mesh control and isolated component.Upper stop member and lower stop member are installed on the upper end or lower end of fastener chain, are to use
In the component for preventing pull head to be detached from.It opens and is usually made of seat stick, socket and plunger from inlay, to be installed under fastener chain
The component of end.It opens from inlay other than the function of preventing pull head to be detached from, also having can connect fastener chain and divide
From function.These are the components usually used in zipper.In addition to that mentioned above, such as pulling-on piece, various dresses can also be made
Ornaments are injection-molded parts.
Injection-molded parts can also be dyed, for the polyester of the such dyeability difference of PTT resin, can also be added
Pigment and be injection moulded.In addition, can also be dyed after injection moulding with further progress.
(4. other component)
The component for constituting zipper can be the component other than injection-molded parts and fiber component.For example, can be by
The transparent membrane of polyester constitutes the reinforcing band of zipper strip.It should be noted that adhesive used in stick carbon fiber band due to
It is not zipper " component parts ", therefore is not necessarily Polyester adhesive, but from the viewpoint of improving recycling property,
It is preferable to use Polyester adhesives.As Polyester adhesive, it is molten that thermoplastic polyester system hotmelt, ultrasonic wave can be enumerated
It connects, bi-component curing adhesive etc..
