Description
Technical Field
The utility model relates to a zipper tooth belt for a zipper. In addition, the present invention relates to a slide fastener and an article provided with the slide fastener.
Background
In addition to daily necessities such as clothing, bags, footwear, and miscellaneous goods, slide fasteners are often used as openers and closers in industrial goods such as tents. In general, a slide fastener is mainly configured by a fastener element tape to which element rows as coupling portions of the slide fastener are attached along side edges of a pair of longitudinal tapes, and a slider which is inserted between the pair of right and left fastener element tapes and controls opening and closing of the slide fastener by coupling and separating the element rows.
As a tape for a slide fastener, a tape made of a woven fabric obtained by weaving warp and weft is often used. The basic structure of a woven tape for a slide fastener is shown in fig. 8. This is shown in FIG. 1 of Japanese examined patent publication (Kokai) No. 5-42731 (patent document 1). The belt is provided with: a fastener element mounting part (4) woven from warp (2) and weft (3); and a belt body portion (5) sewn to the body portion of the article. The element (1) is attached to the element attachment portion (4) by an attachment wire (6). In addition, a border line (7) for preventing fraying can be arranged at the end of the belt main body part (5).
Further, conventionally, there has been known a slide fastener in which a synthetic resin film having waterproofness is attached to fastener tapes in order to impart waterproofness, and the synthetic resin films of the right and left fastener tapes are brought into close contact with each other at the time of engagement to thereby exert waterproofness. For example, international publication No. 2014/013616 (patent document 2) describes the following: a waterproof film made of a thermoplastic elastomer synthetic resin is bonded to an outer surface of a tape member constituting a fastener tape, and a fastener element attaching portion of the tape member is composed of a woven structure of 2/2.
On the other hand, a slide fastener is known which improves the wear resistance of the slider. U.S. patent No. 5596793 (patent document 3) describes a slide fastener (10) of the following type: as shown in fig. 9 of the present application, a core thread (12) penetrates a spiral fastener element (11) formed of a thermoplastic resin, the fastener element (11) is sewn to a side edge of a fastener tape (13) by a double-thread lockstitch means based on a synthetic fiber thread, and when the sewing is performed, a larger tension is applied to a needle thread (15) than a looper thread (14), so that an upper looper portion of the looper thread (14) is melted and cut in a state where a lower looper portion (16) of the looper thread (14) is drawn into the core thread (12), thereby forming a fixed portion (17), and the thread is not exposed to an upper surface of the fastener element (11) fixed to the fastener tape (13).
Further, japanese patent application laid-open No. 2003-47506 (patent document 4) describes the following slide fastener (20): as shown in fig. 10 of the present application, a core material (22) is inserted between upper and lower leg portions (21a, 21b) of a spiral continuous fastener element row (21), and the continuous fastener element row (21) is attached along longitudinal side edges of a fastener tape (23) by upper and lower sewing threads (24a, 24b), and the melting point and the heat shrinkage rate of a constituent material of the core material are lower than the melting point of a constituent material of the continuous fastener element row (21) and higher than the heat shrinkage rate of a constituent material of the continuous fastener element row (21).

SUMMERY OF THE UTILITY MODEL
Problem to be solved by utility model
Currently, in the development of outdoor products, importance is attached to functionality while visual properties such as images and colors are desired. For example, a function of suppressing water penetration from the fastener part can be imparted by attaching a resin film having water repellency to the fastener tape. However, since the resin film is attached to the fastener tape, a problem that the sliding resistance of the slider is increased and the operability of the slide fastener is lowered is likely to occur. Therefore, it is desirable to reduce the sliding resistance of the slider.
In patent document 2, since the element attaching portion of the tape member has a weave structure of 2/2, the main surface of the tape member has a weave structure with many irregularities. When the waterproof film is attached to the tape member, the waterproof film has many recesses reflecting the irregularities of the main surface of the tape member. As a result, the appearance of the waterproof film is impaired, and the slide resistance when the slider is slid to open and close the slide fastener is increased.
In addition, in patent document 3, since the lower looper portion 16 of the looper thread 14 is drawn into the core thread 12 by applying a larger tension to the needle thread 15 than the looper thread 14, the looper thread 14 is further fixed to the core material, the degree of freedom of movement of the fastener element 11 is reduced, and the sliding resistance of the slider is likely to be increased.
In fig. 10 of the present application showing the cross-sectional structure of the fastener stringer described in patent document 4, an interlacing point (25) at which an upper thread (24a) and a lower thread (24b) of a double-lock stitch are interlaced between the fastener elements (21) appears to be located on the upper leg portion (21a) side. However, the cross-sectional configuration of fig. 10 is merely a schematic diagram, and actually: the interlacing point (25) is located on the lower leg portion (21b) side in order to stitch each element (21) to the fastener tape (23). The reason for this is that: as also described in patent document 4, in double lock sewing, a looper thread (24b) as a lower thread (24b) is sewn on a needle thread (24a) as an upper thread (24a) which pierces a fastener tape (23) so as to strongly fasten each element (21) of a continuous fastener element row (21) to the fastener tape (23). Therefore, as in the patent document 3, the degree of freedom of movement of the fastener element (21) is reduced, and the sliding resistance of the slider is likely to be increased.
In the slide fastener provided with the resin film, there is still room for improvement in a means for reducing the sliding resistance of the slider.
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a fastener tape including a resin film and capable of reducing sliding resistance of a slider.

Detailed Description
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. However, the present invention is not limited to the following embodiments, and it should be understood that changes and improvements in design can be appropriately made based on general knowledge of those skilled in the art without departing from the scope of the present invention.
Fig. 1A is a schematic front view of an embodiment of a slide fastener of the present invention. Fig. 1B is a schematic rear view of an embodiment of the slide fastener of the present invention. Fig. 2 is a schematic X-X cross-sectional view of fig. 1B. The slide fastener (100) is provided with: a pair of right and left fastener tapes (101); a resin film (102) which is adhered to the 1 st main surface (101a) of the fastener tape (101); a spiral element row (104) attached to the 2 nd main surface (101b) of each fastener tape (101) along a side edge (103) of the element attachment portion; and a slider (106) which separates and engages the element rows (104) and to which a pull tab (105) is attached. Further, an upper stop (107) is provided at the upper end of the element row (104), and a separable insert (108) is provided at the lower end.
The specific configuration of the slide fastener (100) of fig. 1 is described in detail below. A resin film (102) is stuck to the 1 st main surface (101a) side of the fastener tape (101). The resin film (102) can be attached by using an adhesive or by lamination. The side edge of the resin film (102) on the element row (104) side protrudes relative to the side edge (103) of the fastener tape (101), and abuts against the side edge of the resin film (102) that is opposite thereto. This prevents water from entering through the gap between the right and left fastener tapes (101), and contributes to improvement in waterproofness. The material of the resin film (102) is not limited, but examples thereof include synthetic resins of thermoplastic elastomers such as polyurethane and polyurethane urea.
On the other hand, a spiral resin element is sewn to one side edge (103) of the 2 nd main surface side (101b) of the fastener tape (101) with a sewing thread. As shown in fig. 2, a core wire (110) penetrates through the element row (104). The slider (106) is slidable along the pair of element rows (104), and when the element rows (104) pass through the slider (106), the element rows (104) are engaged or disengaged according to the sliding direction of the slider (106). For example, the element rows (104) are engaged by sliding the slider (106) in the direction of the top stop (107), and the element rows (104) are disengaged by sliding the slider (106) in the direction of the separable bottom end stop (108). Here, the sliding direction coincides with the longitudinal direction (L) of the fastener tape (101). A direction parallel to the main surfaces (101a, 101b) of the fastener tape (101) and orthogonal to the longitudinal direction (L) is referred to as a width direction (W) of the fastener tape (101). In addition, a direction perpendicular to the main surfaces (101a, 101b) of the fastener tape (101) is referred to as a thickness direction (T) of the fastener tape (101).
As each element constituting the spiral element row (104), an element having a flat cross section or an oblong cross section as shown in fig. 6 is preferably used from the viewpoint of facilitating engagement between the elements. By enlarging the cross-sectional shape of a monofilament constituting the fastener element in the longitudinal direction (L) than in the thickness direction (T) of the fastener tape (101), the gap between the fastener element and the core thread (110) penetrating the inside of the fastener element is increased, and the fastener element is more easily moved in the width direction (W) of the fastener tape (101) than when the fastener element is in a perfect circular cross-sectional shape. As a result, no load is applied to the slider (106), and the sliding resistance of the slider (106) is reduced. The fastener element having a flat cross section can be manufactured through a step of pressing a monofilament using, for example, a manufacturing apparatus for a fastener element provided with a core pin described in international publication No. 2015/186200.
Fig. 3 shows an example of a woven structure of a fastener tape (101) used in the present invention. The fastener tape (101) has an element attachment section (201) and a tape main body section (202). The element attaching part (201) is a part to which the element row (104) is attached, and the tape main body part (202) is a part to be sewn to a main body part of the article. The fastener tape (101) may further include an edge portion (203) provided with a ravel-preventing border on the side edge of the tape main body portion (202).
In one embodiment of the slide fastener of the present invention, the element attaching portion (201) is a woven structure of 1/1. In the present invention, the 1/1 weave refers to the following weave: after doubling or non-doubling, 1 warp yarn was placed on 1 weft yarn obtained by doubling two warp yarns, and then 1 weft yarn was sunk. When the element attaching portion (201) is formed of the woven structure of 1/1, the main surfaces (101a, 101b) of the fastener tape (101) are less uneven and smooth. As a result, even if the resin film (102) is stuck to the 1 st main surface (101a) of the fastener tape (101), the slider (106) can be smoothly operated without generating a large sliding resistance. On the other hand, when the fastener tape has a knitted fabric structure of 2/2 as described in patent document 2, unevenness is likely to occur on the main surface of the fastener tape, and the sliding resistance of the slider increases. An example of the weave pattern of 1/1 is a rib weave pattern as shown in fig. 3. The resurfacing tissue is the following: two warp yarns doubled to 1 warp yarn were placed on 1 weft yarn doubled to 1 weft yarn, and then 1 warp yarn was sunk.
In addition, the element attachment portion (201) is formed of a woven fabric of 1/1, so that the element attachment portion (201) is hardened. This can reduce the tension of the suture when the fastener element is sutured, and can facilitate the movement of the fastener element. On the other hand, when the element attaching part (201) is a soft woven structure (for example, twill structure), if the tension of the suture thread at the time of sewing the element is weakened, a defect such as thread fastening failure is likely to occur.
As described above, as a result of specifying the weave structure, in one embodiment of the slide fastener of the present invention, the thickness of the element attaching portion (201) of the fastener tape (101) can be adjusted to preferably 0.30mm to 0.6mm, more preferably 0.30mm to 0.5mm, and still more preferably 0.30mm to 0.35 mm. Further, the thickness of the fastener tape (101) is measured by japanese industrial standard JISL 1096: 2010, according to the JIS method described herein.
Since the element attachment portion (201) is a woven structure of 1/1, the thickness of the fastener tape (101) is small. Therefore, in order to improve the stability of the fastener element mounting form and the mounting strength, the warp threads in the fastener element mounting portion (201) may be doubled up by two or more. In order to improve the stability of the attachment form of the fastener element and the attachment strength, it is preferable to increase the number of the combined filaments. However, if the number of the parallel threads is excessively increased, the tape becomes excessively thick, and the sliding resistance of the slider (106) increases. Therefore, the number of the parallel yarns included in 1 warp yarn row is preferably two to 3, more preferably two. Further, by arranging 1 warp yarn with a shifted weaving position between adjacent warp yarn rows, excessive lifting of the yarn and deviation of the weave can be prevented.
In order to reduce the sliding resistance of the slider (106), it is desirable to use a relatively thin thread as the thread constituting the fastener tape (101). By using thin thread, the unevenness of the main surfaces (101a, 101b) of the fastener tape (101) is reduced, and therefore, the sliding resistance of the slider (106) can be reduced. Therefore, the fineness of each thread is preferably 700 dtex or less, more preferably 522 dtex or less. However, if the thread constituting the fastener tape is too thin, a fastener tape having sufficient strength cannot be obtained, and therefore, the fineness of each thread is preferably 139 dtex or more, and more preferably 161 dtex or more.
The yarn may be formed of either a monofilament or a multifilament, but one yarn may be formed of a monofilament, may be formed of a multifilament obtained by bundling two or more monofilaments, or may be formed of a plurality of multifilaments. For example, a yarn composed of two multifilaments in which 50 monofilaments of 5 dtex are bundled is 1 yarn of 500 dtex.
In addition, from the viewpoint of making the fastener tape (101) flexible and reducing the sliding resistance of the slider (106), the warp and weft constituting the woven structure of at least the element attaching portion (201), preferably the warp and weft constituting the entire fastener tape (101), are preferably multifilament yarns formed by bundling filaments preferably at least 60, more preferably at least 70, further preferably at least 80, and further preferably at least 90. The fineness of the warp and weft is preferably 150 dtex or more, more preferably 200 dtex or more, further preferably 250 dtex or more, further preferably 300 dtex or more, and further preferably 350 dtex or more. The fineness is the fineness before the yarn is doubled. Therefore, for example, when a 167 dtex thread formed by bundling 96 monofilaments is used as the weft thread, the weft thread is substantially in a state of being doubled in the fastener tape (101), and therefore, the weft thread is 334 dtex thread formed by bundling 192 monofilaments.
As a material of the thread used for the fastener tape of the present invention, conventionally used polyester, polyamide, polypropylene, acrylic, or the like can be used, but polyester is preferable in view of the reason that the sewing property is good, the material strength is high, or the like.
On the other hand, in the belt main body portion (202), the weave is not particularly limited. In fig. 3, the belt body (202) is formed by a combination of a rib weave and a twill weave. Further, the twill weave is a weave pattern of 2/2: two warp yarns are placed on the 1 weft yarn formed by doubling two warp yarns, and then two warp yarns are sunk below the warp yarns.
Fig. 4 shows a modified example of the weave of the element attaching portion (201) which can be used in the present invention. In fig. 4, the element attaching portion (201) is formed of a plain weave. Further, the plain weave refers to a weave of: as shown in fig. 4, 1 warp (a) which is not doubled is placed 1 weft on which two warps are doubled to become 1 weft, and then 1 warp is sunk.
Fig. 5 is a schematic partial front view of an embodiment of the fastener stringer of the present invention. Fig. 6 is a schematic Y-Y cross-sectional view of fig. 5. Fig. 7 is a schematic Z-Z cross-sectional view of fig. 5. The element row (104) is attached along the side edge (103) of the element attachment portion (201) of the fastener tape (101) by a sewing thread (109). Here, as shown in fig. 6, each element of the element row (104) has: an upper leg portion (112) extending in the width direction (W) of the fastener tape (101) and spaced apart from the 2 nd main surface (101 b); and a lower leg portion (113) that extends in the width direction (W) of the fastener tape (101) and contacts the 2 nd main surface (101 b). Each element has an engaging head (114) for connecting the upper leg (112) and the lower leg (113). The coupling head (114) can be coupled to or separated from the coupling head (114) of the opposite element, and thus the open/close state of the slide fastener can be controlled. Each element has a coupling section (115) at a position facing the coupling head section (114) along the width direction (W) of the fastener tape (101). The connecting section (115) connects the adjacent elements of the spiral element row (104) between the upper leg section (112) and the lower leg section (113). The sewing thread (109) is composed of a 1 st thread (109a) and a 2 nd thread (109b), wherein the 1 st thread (109a) forms a 1 st sewing thread on the 1 st main surface (101a) side, and the 2 nd thread (109b) forms a 2 nd sewing thread on the upper leg portion (112) side, and is interwoven with the 1 st thread (109a) between the fastener elements.
In an embodiment of the fastener element tape of the present invention, as shown in fig. 5 to 7, the element row (104) can be sewn to the fastener tape (101) by a double-line lock stitch based on the 1 st thread (109a) and the 2 nd thread (109 b). A needle thread as a 1 st thread (109a) is sequentially pierced with a core thread (110) between the elements of the element row (104) from the 1 st main surface (101a) side to the 2 nd main surface (101b) side of the fastener tape (101), and is interlaced with a looper thread as a 2 nd thread (109b) across the upper leg portion (112) of each element (140), and the element row (104) is sewn to the fastener tape (101). The needle thread and the loop of the looper thread are interlaced, and each fastener element is attached to the fastener tape (101).
In an embodiment of the fastener stringer of the present invention, as shown in fig. 6, an intersection point (111) of the 1 st thread (109a) and the 2 nd thread (109b) is located closer to the upper leg portion (112) than a center point (C) of the fastener tape (101) between the upper leg portion (112) and the lower leg portion (113) in the thickness direction (T). The fact that the interlacing point (111) is located at such a position means that the force with which the 1 st thread (109a) fastens each element to the fastener tape (101) is weak, and the effect that each element is easily moved is obtained. This can reduce the sliding resistance of the slider (106).
In a preferred embodiment, from the viewpoint of ensuring the attachment strength of the fastener element row (104) to the fastener tape (101), the ratio (D/D) of the distance (D) from the intersection (111) of the lower end edge (113a) in the thickness direction (T) of the lower leg portion (113) to the distance (D) between the upper end edge (112a) in the thickness direction (T) of the upper leg portion (112) and the lower end edge (113a) in the thickness direction (T) of the lower leg portion (113) is, on average, 110% or less, more preferably 100% or less, still more preferably 90% or less. However, from the viewpoint of reducing the sliding resistance of the slider, D/D is preferably 40% or more on average, more preferably 50% or more on average, still more preferably 60% or more on average, and still more preferably 80% or more on average. The intersection (111) is a position of the 1 st line (109a) and the 2 nd line (109b) which are farthest from the 1 st line (109a) on the 2 nd main surface (101b) side of the fastener tape (101) in the thickness direction (T) in a portion where the 1 st line (109a) and the 2 nd line (109b) are interlaced between two adjacent fastener elements.
In the interval (P) (pitch) between the centers of two adjacent fastener elements in the longitudinal direction (L), the average length of the 1 st line (109a) is preferably longer than the average length of the 2 nd line (109 b). That is, by reducing the fastening degree of the 1 st thread (109a), friction between the fastener tape (101) or each element and the slider (106) during sliding is suppressed, and therefore, sliding resistance of the slider (106) can be reduced. When a cross section of the fastener tape (101) parallel to both the longitudinal direction and the thickness direction is observed in a CT image, the average length of the 1 st line (109a) is preferably 1.3 times or more, more preferably 1.5 times or more the average length of the 2 nd line (109 b). However, from the viewpoint of securing the attachment strength of the fastener element row (104) to the fastener tape (101), the average length of the 1 st thread (109a) is preferably twice or less, more preferably 1.9 times or less, the average length of the 2 nd thread (109 b). The lengths of the 1 st line (109a) and the 2 nd line (109b) are measured along the center line of the line when viewed in a CT image. Further, an average value is calculated based on the length measurement results of 10 or more sites.
In the case of double-thread lock stitch, in order to compensate for the attachment strength of the element row (104), as shown in fig. 7, it is preferable that the spiral element row (104) is sewn to the element attaching portion (201) by two needle threads and 1 looper thread.
It is desirable that the 2 nd wire (109b) has a smaller moist heat shrinkage rate than the 1 st wire (109 a). With this arrangement, the contraction of the 2 nd thread (109b) is smaller than that of the 1 st thread (109a), and the elements are easy to move, so that the sliding resistance of the slider (106) can be reduced. Examples of the method for reducing the wet heat shrinkage rate include the following methods: for example, the 2 nd thread (109b) is a pre-dyed thread obtained by dyeing a thread before sewing the fastener tape (101) with a thread. On the other hand, the 1 st thread (109a) may be either a first dyed thread or a second dyed thread.
Here, the wet heat shrinkage rate is calculated based on the following formula (1).
Moisture-heat shrinkage (%) {1- (length of wire after moisture-heat treatment/length of wire before moisture-heat treatment) } × 100. equation (1)
The wet heat treatment conditions and the method of measuring the length of the wire are as follows.
< Condition of Wet Heat treatment >
Damp Heat treatment in pressurized Water of 0.2MPaG
Water temperature: 130 deg.C
Time: 30 minutes
< method for measuring line Length >
Load of 10 mg/dtex
In order to reduce the sliding resistance of the slider (106), in one embodiment of the slide fastener of the present invention, it is preferable that a softening agent is adhered to the entire surface of the element row (104). Examples of the softening agent include paraffin-based, cationic-based, nonionic-based, composite-based, and silicon-based ones.
The slide fastener of the present invention can be used as an opening/closing tool for articles by sewing the slide fastener to various articles, and can be used for openings of clothing, pockets, bags, shoes (e.g., boots, booties), tents, mattresses, vehicle seats, and the like.
[ examples ] A method for producing a compound
The following examples of the present invention are shown together with comparative examples, but these examples are provided for better understanding of the present invention and its advantages, and are not intended to limit the present invention.
(example 1)
A polyester fastener tape (101) (thickness: 0.35mm) having the fastener element attaching part (201) and the tape main body part both having the weave structure described in Table 1 was prepared. As warp and weft constituting the fastener tape (101), 167 dtex multifilament made of 96 monofilaments bundled together was used. Then, the element row (104) through which the core thread (110) has been inserted is sewn to the 2 nd main surface (101b) of the fastener tape (101) by a double-thread lockstitch sewing machine through a double-thread lockstitch along the side edge (103) on the element attaching portion (201) side. The sewing thread (109) is composed of a polyester needle thread (344 dtex) forming a 1 st sewing thread on the 1 st main surface (101a) side of the fastener tape (101) and a polyester looper thread (344 dtex) forming a 2 nd sewing thread on the upper leg portion (112) side of the fastener element.
With respect to the obtained element row, the interval (P) (pitch) in the longitudinal direction (L) between two adjacent elements was 1.25 mm. Further, the distance (D) between the upper end edge (112a) of the upper leg portion (112) in the thickness direction (T) and the lower end edge (113a) of the lower leg portion (113) in the thickness direction (T) is 1.35 mm.
Then, a 2-liquid-curable urethane resin was applied to the 1 st main surface (101a) of the fastener tape (101), and then cured to form a urethane resin film (102) (thickness: 0.05mm), thereby obtaining a fastener tape. At this time, a needle thread made of polyester, which forms a 1 st sewing thread on the 1 st main surface (101a) side of the fastener tape (101), is fixed by being brought into contact with the resin film. The obtained fastener element tape was used to assemble a waterproof fastener (100) having the structure shown in fig. 1 and 2.
< position of interleaving Point >
The obtained slide fastener (100) was cut so that the cross section was exposed along the longitudinal direction (L) of the fastener tape (101), the cross section of the slide fastener (100) shown in fig. 6 was observed by an X-ray CT scanner, the parameters (D/D) relating to the positions of the interlacing points of 10 portions were measured in accordance with the above definition, and the average value of these was taken as the measurement value. The results are shown in table 1.
< length of suture line >
From the obtained slide fastener (100), the average value of the lengths (lengths in cross section) of the needle thread and the looper thread between two adjacent fastener elements is measured by X-ray CT scanning, and the ratio of the average length of the needle thread to the average length of the looper thread in the interval (P) in the longitudinal direction (L) of the two adjacent fastener elements is determined.
< sliding resistance test >
The sliding resistance test was carried out according to japanese industrial standard JIS 3015: 2007 was calculated by the following method.
A pull tab (105) of a slider (106) of each of the slide fasteners (100) of the test examples was pulled up in the longitudinal direction (L) of the fastener tape (101) to close the slide fastener (100). Then, the slide fastener (100) was fixed to a jig of a tensile testing machine, pulled at a constant speed of 1000mm/min, set to a stroke of 100mm, and a stable value of the sliding resistance in the direction of opening the slide fastener (100) (an average value of values between 100mm excluding the maximum value and the minimum value) was measured. Then, a pull tab (105) of a slider (106) of the obtained slide fastener (100) is pulled down in the longitudinal direction (L) of the fastener tape (101) to open the slide fastener (100). Then, the slide fastener (100) was fixed to a jig of the tensile testing machine, and was pulled at a constant speed of 1000mm/min, the stroke was set to 100mm, and a stable value of the sliding resistance in the direction of closing the slide fastener (100) (an average value of values between 100mm excluding the maximum value and the minimum value) was measured. The value obtained by averaging the stable values of these sliding resistances is defined as the sliding resistance value. The results are shown in table 1.
< appearance of resin film >
The evaluation plane (projection plane) of the resin film (102) of the obtained slide fastener (100) was visually observed according to the following evaluation criteria. The results are shown in table 1.
Evaluation criteria
And 5, dividing: no opaqueness was observed, or generation of less than 0.2mm was discontinuous2White turbidity of size (D)
And 4, dividing: discontinuously generating 0.2mm2Above and less than 0.4mm2White turbidity of size (D)
And 3, dividing: continuously produce 0.2mm2Above and less than 0.4mm2White turbidity of size (D)
And 2, dividing: continuously produce 0.4mm2Above and less than 0.8mm2White turbidity of size (D)
1 minute: continuously produce 0.8mm2White turbidity of the above size
(example 2)
A slide fastener was produced in the same manner as in example 1 except that the fastener element attaching portion of the fastener tape and the loop weave of the tape main body portion were changed to a plain weave, and characteristic evaluation in the same manner as that in example 1 was carried out. The results are shown in table 1.
(example 3)
A slide fastener was produced in the same manner as in example 1 except that the rib structure of the element attaching portion and the tape main body portion of the fastener tape was changed to a twill structure, and characteristic evaluation similar to that of example 1 was performed. The results are shown in table 1.
(example 4)
A slide fastener was produced in the same manner as in example 1 except that the degree of fastening of the fastener elements with the needle thread was increased and the position of the interlacing point was changed as compared with example 1, and characteristic evaluation in the same manner as that in example 1 was performed. The results are shown in table 1.
(example 5)
A slide fastener was produced in the same manner as in example 2 except that the degree of fastening of the needle thread to the fastener element was increased and the position of the interlacing point was changed as compared with example 2, and characteristic evaluation similar to that of example 2 was performed. The results are shown in table 1.
Comparative example 1
A slide fastener was produced in the same manner as in example 3 except that the degree of fastening of the needle thread to the fastener element was increased and the position of the interlacing point was changed as compared with example 3, and characteristic evaluation similar to that of example 3 was performed. The results are shown in table 1.
[ TABLE 1 ]
(examination)
As can be seen from the results in table 1, it can be understood that: the element attachment portion is formed of a woven fabric of 1/1, so that the sliding resistance of the slider is intentionally reduced. In addition, it is known that: the resin film is smoothed and the appearance is improved. Further, it is also known that: by setting the position of the interlacing point to the upper leg portion side, the sliding resistance of the slider can be reduced.
Further, in the case where the upper thread is short, the sliding resistance does not differ greatly depending on the weave (example 4, example 5, and comparative example 1), but the warp threads are hard to move in example 4 and example 5 of the weave in which the element attaching portion is 1/1 as compared with comparative example 1, and therefore, such an advantage is obtained: the hole is difficult to expand during needling, and the needle thread is difficult to be tied into the belt.
