(manufacture methods of 2. fastener chains)

Then, for the present invention fastener chain manufacture method an example, illustrated while with reference to Fig. 4.First, it is accurate Standby fastener chain 21, the fastener chain 21 possess a lateral margin a pair of of zipper strip of adjoining and installation at a prescribed interval each other Chain denture in the main surface of a foregoing lateral margin for each zipper strip.Form the explanation of the component of fastener chain 21 as previously described.

Next, the melt viscosity at 200 DEG C is in polyester and resin composition 22 in aforementioned range in mould 23 Exit is extruded at 150~250 DEG C, and is in the main surface as each zipper strip and the main surface with being provided with chain denture Conversely curtain coating polyester and resin composition 22 in the main surface of side and on foregoing interval (s).Polyester and resin composition squeezes Going out can for example implement by using the usual extrusion moulding of extruder 24 and mould 23.On polyester and resin composition The setting reason of melt viscosity at 200 DEG C of 22, as previously described.Make the polyester and resin composition 22 in the exit of mould 23 Temperature be 150 DEG C above is in order to make the resin combination become the viscosity that can be coated with.Polyester resin group at mould outlet The temperature of compound is preferably more than 170 DEG C, more preferably more than 190 DEG C.Make the temperature of the polyester and resin composition at mould outlet Spend for less than 250 DEG C be the resin combination in order to prevent heat deterioration.The temperature of polyester and resin composition at mould outlet Preferably less than 230 DEG C, more preferably less than 210 DEG C.

Polyester and resin composition is preferably coated in the main surface of zipper strip by curtain coating.Just from mould outlet The polyester and resin composition of discharge is high temperature and mobility is higher, if therefore being pressed into zipper strip, polyester with elevated pressures Resin combination is easily accessible in the gap produced by the interval (s) for being arranged on a pair of of slide fastener interband.If polyester resin composition Thing is excessively entering into the gap, then can be contacted with pull head, thus be likely to occur due to the slip of pull head waterproof coating it is damaged this The unfavorable condition of sample.

This point, in the case of curtain coating, from the molten polyester resin composition that mould outlet is discharged in discharge Pressure be discharged into air after, reach in the main surface of zipper strip, therefore, can make from polyester and resin composition to slide fastener The extruding of the main surface of band is smaller.Thus, it is possible to prevent polyester and resin composition from entering with inappropriate degree by being arranged on one In the gap produced to the interval (s) of slide fastener interband.

In addition, there is the polyester and resin composition of regulation melt viscosity by curtain coating, can be by intended shape and ruler Very little polyester and resin composition is laminated on zipper strip.Therefore, according to the shape and size of mould outlet, can be desirably Thickness, amplitude are coated with, and can also be coated with and become band with uniform thickness.While fastener chain is conveyed in its length direction, Then it is favourable in industrial production while implementing curtain coating.

Width of the mould outlet preferably across a pair of of zipper strip is overall and extends.Thus, it is possible in a pair of of zipper strip Main surface on along the width of band form continual waterproof coating.In addition, it is coated on the polyester resin on zipper strip The thickness of composition can be controlled by adjusting the slit width (w) of mould outlet.The reasons why being kept from the intensity of resin bed Set out, which is preferably set to more than 0.01mm, is more preferably set to more than 0.05mm, is still more preferably set to More than 0.1mm.In addition, weight increase and flexibility decline caused by the thickness of resin bed becomes larger in order to prevent, the slit Width (w) is preferably set to below 0.8mm, is more preferably set to below 0.4mm, is further preferably set to below 0.25mm.

Using curtain coating, the pressure to zipper strip main surface from the polyester and resin composition that mould outlet is discharged can be made For below 1MPa, if the pressure of the scope, then it can effectively inhibit polyester and resin composition depth and enter a pair of of slide fastener In the gap of interband.The pressure is preferably below 0.8MPa, more preferably below 0.5MPa.Wherein, if being discharged from mould outlet Polyester and resin composition it is too small to the pressure of zipper strip main surface, then resin will not enter zipper strip fiber between so that Contiguity degree declines, therefore the pressure is preferably set to more than 0.1MPa, is more preferably set to more than 0.2MPa.

In the present invention, which can measure as follows：Pressure gauge is set in the lower section of zipper strip, and makes polyester resin composition Thing continuously flows, so as to measure the pressure applied to zipper strip.

As shown in figure 4, the polyester and resin composition from mould outlet discharge can pass through the pressure of zipper strip main surface Adjust from distance (g) of the mould outlet untill the zipper strip main surface of curtain coating polyester resin to control, for example, should (g) It can be set to 0.1~2.0mm.It is preferred based on the viewpoint for not making mould be contacted with the surface irregular zipper strip of tool, the distance (g) More than 0.1mm is set to, is more preferably set to more than 0.3mm, is still more preferably more than 0.5mm.Go out from holding from mould outlet From the viewpoint of the shape come, which is preferably set to below 2.0mm, is more preferably set to below 1.5mm, further excellent Choosing is set to below 1.0mm.

As shown in figure 4, in the main surface of zipper strip after curtain coating polyester and resin composition 22, from polyester resin The metal roller 25 for being heated to 100~250 DEG C of composition coating surface side is with coming from the uncoated face (slide fastener of polyester resin Band) side 5~50 ° of hardness roller 26 between, while being pressurizeed with 0.1~10.0Mpa to fastener chain 21, while being passed to. By the process, polyester resin moderately enters in the fine bumps in the main surface of zipper strip, so that real based on anchoring effect The raising of existing bonding strength.After curtain coating, continuously implement the work when fastener chain is conveyed in its longitudinal direction Sequence, is favourable in industrial production.

In polyester and resin composition coating surface side following reasons are in order at using metal roller 25：It is mechanical strength, heat-resisting Property and flatness are excellent, and are coated on the polyester and resin composition on zipper strip and have difficulty adhering on roller.By the way that roller 25 is added To 100~250 DEG C, polyester and resin composition softens and enters further into the fine bumps of zipper strip heat, can obtain more Firm anchoring effect.The reasons why for the softening for promoting polyester and resin composition, preferably 120 DEG C of the heating-up temperature of roller 25 with On, more preferably more than 150 DEG C.In addition, from the viewpoint of the heat deterioration for preventing polyester and resin composition, the heating-up temperature of roller 25 It is preferred that less than 220 DEG C, more preferably less than 200 DEG C.

By using the soft roller 26 of 5~50 ° of hardness in the uncoated face of polyester and resin composition (zipper strip) side, then exist When fastener chain passes through roller, the surface of roller can follow the fine bumps of zipper strip main surface and deform, and therefore, further promote The bonding of polyester resin and zipper strip, can reduce Poor cohesion portion.The hardness of roller is set to 5 ° above is due to following reason： Prevent because being plastically deformed caused by the excessively softness of roller, be preferably more than 7 °, more preferably more than 10 °.In addition, by roller It is due to following reason that hardness, which is set to less than 50 °,：Prevent from hindering to follow fine bumps because roller is really up to the mark, be preferably 40 ° Hereinafter, less than 30 ° are more preferably.As the material of the hardness with above range, do not limit, organosilicon tree can be enumerated Fat, polyflon, rubber rollers etc., for prolonged flexibility it is lasting the reasons why, preferred organic siliconresin.

In the present invention, the hardness of roller measures by the following method.According to JIS K6253 (2006), hardometer is pressed against Roller surface measures hardness.

The roller 26 of the uncoated face of polyester and resin composition (zipper strip) side need not be heated.If heat zipper strip side Roller, then cause band to be themselves directly heated due to no coating resin, this allows for the thermal deformation of zipper strip itself Possibility.

Pressure during for the fastener chain that makes to be coated with polyester and resin composition by between these rollers, from making roller and tree From the viewpoint of oil/fat composition coated face reliably touches, more than 0.5MPa is preferably set to, is more preferably set to more than 1.0MPa, more Further it is set to more than 1.5MPa.From the viewpoint of the leakage of resin bed caused by preventing pressure too strong, which preferably sets For below 10MPa, below 5MPa is more preferably set to, is further set to below 2MPa.

In the present invention, for roller by when the pressure measure as follows：Between zipper strip is clipped in roller, basis is utilized The spring-tube pressure gauge of JIS B7505 (1999), surface side is coated with to the uncoated surface side roller extrusion resin composition of resin combination The pressure of roller is measured.

Then, by the way that the foregoing polyester resin on fastener chain is cooled and solidified, waterproof coating is securely fixed in slide fastener In the main surface of band.As cooling condition, air can be blowed to belt surface and cooled down.In the case of rapid cooling resin, Occur deformation excessive as caused by contraction, therefore for the reasons why preventing its generation, wind speed at this time be preferably 30m/s with Under, more preferably below 20m/s, is even more preferably below 10m/s.The refrigerating work procedure is also in roller pressurization back by slide fastener chain Bar conveys side in its longitudinal direction continuously to be implemented, this is industrially favourable.

In the present invention, which utilizes and is measured according to the airspeedometer of JIS T8202 (1997).

Afterwards, the waterproof coating that will be formed on the foregoing interval (s) of fastener chain is cut off between the interval.It is preferred that edge The center line A cut-outs at the interval.Such as cut off using cutting machine (not shown).The cut off operation is also that side will be drawn Chain chain is continuously implemented on its length direction conveying side, this is industrially favourable.
