Problems solved by technology

[0007] In addition, the installation interval (pitch) of the fastener elements should be set in consideration of the expansion and contraction of the fastener tape. When the zipper elements are tilted or slightly moved, the spacing between them will be widened and the meshing strength will be reduced.

no. 1 Embodiment approach

[0036] First, refer to Figure 1 to Figure 7 1st Embodiment of the slide fastener which concerns on this invention is demonstrated.

[0037] Such as figure 1 As shown, the slide fastener 10 of the present embodiment includes: a pair of left and right zipper tapes 20 of textile; a pair of left and right cores 20a, which are respectively arranged along the opposite tape side edges of the left and right pair of zipper tapes 20; a pair of left and right zipper tapes Element rows 30, which are respectively mounted on the left and right pair of core parts 20a, have a plurality of metal zipper elements 31; slider 40, which engages and separates the left and right pair of zipper element rows 30; the upper stop part 11 , which are respectively arranged on the upper end of the left and right pair of zipper element rows 30; In addition, although the application of the slide fastener 10 is mentioned, clothing, a bag, a shoe, industrial goods etc. are mentioned, It is not limited to this...

no. 2 Embodiment approach

[0055] Next, refer to Figure 8 The second embodiment of the slide fastener of the present invention will be described. It should be noted that the same or equivalent parts as those of the above-mentioned first embodiment are assigned the same reference numerals in the drawings, and descriptions thereof are omitted or simplified.

[0056] In this embodiment, silica (silicon oxide) S (refer to Figure 4 ), and on the left and right fastener tapes 20, an anti-seepage agent and a fluorine-based compound are attached. and, if Figure 8 As shown, a predetermined pattern (color) P is formed by inkjet printing (coloring) on ​​the fastener tape 20 , the fastener element 31 , and the fastener tape 20 portion in the vicinity of the fastener element 31 .

[0057] In addition, an opener 13 is provided instead of the lower stopper portion 12 of the first embodiment described above, and the opener 13 includes a box bar 14 and a box body 15 provided at the lower end of the zipper element ...

Embodiment

[0066] Next, in order to confirm the effects of the present invention, a top strength test was performed on the slide fasteners of the present invention and the slide fasteners of the comparative example.

[0067] In this test, slide fasteners 1 to 5 (No. 1 to No. 5) described below were prepared. In addition, as a general specification of the slide fasteners 1 to 5, a fastener tape woven from a polyester thread material is used, and fastener elements are made of red copper. also, Figure 9 The manufacturing process of slide fasteners 1-5 is shown in .

[0068] The slide fastener 1 is a slide fastener in which fastener elements are attached to the core of the fastener tape, and corresponds to a normal slide fastener.

[0069] The slide fastener 2 attaches fastener elements to the core part of a fastener tape, after making an anti-seepage agent adhere to a fastener tape.

[0070] The slide fastener 3 attaches the fastener element to the core part of the fastener tape after a...

Abstract

Provided is a slide fastener that is capable of maintaining the operability of a slider while improving the engagement strength of a fastener element. The present invention comprises a pair of fastener tapes (20), a pair of cores (20a) that are respectively disposed along opposing tape side edges of the pair of fastener tapes (20), and a pair of fastener element rows (30) that are respectively attached to the pair of cores (20a) and include a plurality of metallic fastener elements (31). Silica (S) is adhered to surfaces of the cores (20a) and the fastener elements (31).

Description

technical field [0001] The present invention relates to zippers. Background technique [0002] As a slide fastener, there is known a slide fastener as follows, which includes: a pair of slide fastener tapes; a pair of core ropes, which are respectively provided on opposite tape side edge portions of a pair of slide fastener tapes; a pair of slide fastener element rows, which are respectively provided on A pair of core ropes has a plurality of metal zipper elements; a slider engages and separates a pair of zipper elements. [0003] In addition, it is important for the zipper to maintain the meshing state, and various tests are performed in order to have a prescribed meshing strength. As this test, there are, for example, a test for measuring the meshing strength between fastener elements by holding a pair of fastener tapes in a meshed state and pulling the tapes on a horizontal plane in a direction in which the tapes are separated from each other (flat pull strength test), ...
