Measured value of surface roughness in the case of calendering

1st:

Arithmetic mean height Sa = 0.078mm

Maximum height Sz=0.477mm

Aspect ratio of surface features Str = 0.513

The expanded area ratio of the interface Sdr=0.0056255

2nd:

Arithmetic mean height Sa = 0.096mm

Maximum height Sz=0.521mm

Aspect ratio of surface features Str = 0.733

The expanded area ratio of the interface Sdr=0.0054392

Measured value of surface roughness without calendering

1st:

Arithmetic mean height Sa=0.107mm

Maximum height Sz=0.964mm

Aspect ratio of surface features Str = 0.135

The expanded area ratio of the interface Sdr=0.0475920

In the calendering process ST3, the calendering process by heat-pressing processing is performed with respect to the upper surface 22 of the fastener tape 20 using the calendering process apparatus 50 shown in FIG. The heating and pressure treatment refers to a treatment of applying pressure to the fastener tape 20 so that the dimension in the vertical direction of the fastener tape 20 is smaller than that in the case of non-pressurization, while applying heat to the fastener tape 20 .

As shown in FIG. 4 , the calendering apparatus 50 includes a heating roll 51 made of metal such as iron, and a rigid roll 52 formed of an epoxy resin or the like and arranged to face the heating roll 51 . Moreover, as shown in FIG. 5, the width|variety of the rotation axis direction of the heating roller 51 and the width|variety of the rotation axis direction of the rigid body roller 52 are set to the dimension which can handle a pair of fastener element tapes 10 at the same time.

In addition, the rigid body roller 52 may be an elastic roller, a paper roller, a cotton roller, or the like.

When the pair of fastener element tapes 10 are calendered using the calendering apparatus 50 configured in this way, after heating the heating roll 51 to a predetermined temperature, the heating roll 51 and the rigid body roll 52 are heated to a predetermined temperature. A pair of fastener element tapes 10 are supplied between the rotating heating roller 51 and the rigid body roller 52 .

At this time, the fastener tape 20 is passed between the heating roller 51 and the rigid roller 52, and the heating roller 51 and the rigid roller 52 press the fastener tape in the tape thickness direction while heating the upper surface 22 of the fastener tape 20 by the heating roller 51. 20.

For example, in the case of polyester yarn, the heating temperature of the fastener tape 20 is preferably 150°C to 250°C. In addition, the roll pressure is preferably 100 mN to 200 mN, for example. In addition, when the fastener tape 20 is comprised by the yarn which consists of multiple resins, the heating temperature of the fastener tape 20 is set to be lower than the lowest softening point among these yarns. Furthermore, by setting the heating temperature of the fastener tape 20 as described above, the fusion of the yarns constituting the fastener tape 20 and the fusion of the yarns can be prevented, and the softness of the fastener tape 20 can be maintained.

And the fastener tape 20 is heated and pressurized, maintaining the shape of the fastener element row 30 by applying the above-mentioned calendering process to the fastener element tape 10. Thereby, the cross section of the yarn constituting the fastener tape 20 is deformed into a flat shape, and the upper surface 22 of the fastener tape 20 is flattened.
