Description
Technical Field
The present invention relates to a fastener chain in which a widthwise intermediate portion is closed, and a slide fastener including a slider for opening and closing the widthwise intermediate portion of the fastener chain in a longitudinal direction of the fastener chain, and the fastener chain.
In the present specification, the expression "a tab" and a back "will be used to refer to a case where a slide fastener is attached to a product such as clothing or a bag, and the case where the slide fastener is exposed to the outside in a normal use state of the product, in other words, a case where the slide fastener is attached to the tape tab side of the slider. The expression front and back are also used in the same sense in this specification.
Background
As an example of a conventional hydrophobic treatment method for a fastener chain, a technique is known in which the fastener chain is passed through a water repellent agent filled in a container, and thereafter the fastener chain is dried to attach the water repellent agent to the fastener chain (patent document 1). Generally, the fastener forms a small gap in the engagement portion of the fastener element, and forms a gap between the pair of right and left tapes to a certain extent, so that water is likely to permeate therethrough. Accordingly, in the slide fastener disclosed in patent document 1, in addition to the specification of using the fastener element side as the back side, commonly called "specification for the back side", a liquid-tight surface formed of a resin film or the like is further provided on the entire front surface of the fastener tape on the front side, and in order to prevent water from penetrating through a gap between the pair of left and right tapes, the fastener chain is passed through a water repellent, and the fastener element portion and the back surface of the fastener tape are subjected to a water repellent treatment.
As another example of the conventional hydrophobic treatment method of the fastener chain, the following techniques are known: the lower part of the roller is immersed in a water repellent filled in a container, and the roller is rotated, whereby the water repellent is attached to the upper front surface of the roller, the fastener elements of the fastener chain are pressed against the upper front surface of the roller to apply the water repellent, and thereafter the fastener chain is passed through a vacuum part so that the water repellent is attached to a wire for fixing the fastener elements to the tape and a hole through which the tape is passed (patent document 2). Although the slide fastener described in patent document 2 is not clearly for the back side or the front side, not only the tape but also the fastener element is coated with a water repellent agent in advance. The "front face" is a specification in which the element side is used for the front face.
Patent document 3 also describes that in order to prevent the water from penetrating through the gap between the element engaging portion and the gap between the pair of left and right bands, it is considered to perform a waterproof process on the element.
In order to provide a fastener with a sufficient water repellent effect, it has been conventionally thought to positively apply a water repellent to fastener elements.
In recent years, environmental protection awareness of the entire society has increased, and it has been demanded to prevent environmental pollution as much as possible. In recent years, environmental protection has been increasing, and the amount of water repellent and substances which have been considered to be used without any particular problem have been limited, and there is a demand for reducing the amount of fluorine-based water repellent which has a good effect as a water repellent material.
Under such a change in environmental awareness, a technique disclosed in patent document 4 has been proposed as a technique capable of performing a water repellent treatment on an object even if a large amount of water repellent is applied without using water and then dried.
Patent document 4 discloses, as an example of a hydrophobic treatment method for a substrate, the following: the curable coating composition containing a polymerizable monomer is applied to a substrate, and the polymerizable monomer is polymerized under specific conditions, so that the curable coating composition becomes an organic polymer coating layer, and as a result, the organic polymer coating layer is attached to the substrate. The hydrophobic treatment method of the base material disclosed in patent document 4 is described as a representative example of use, but is also described as being widely applicable to leather products, electronic parts, and the like other than fibers, and is also described as being applicable to buttons and zippers.

Disclosure of Invention
However, as the water repellent treatment method of the base material disclosed in patent document 4, there is no description of an example actually applied to a fastener chain, and there is no study on how to treat the fastener element portion of the fastener chain. As described above, in order to provide a fastener with a sufficient water repellent effect, it is currently considered to positively apply a water repellent agent to fastener elements. However, the fastener chain and the slide fastener are required to have not only hydrophobicity but also flexibility.
However, the inventors of the present invention have found that when the water repellent treatment method of the base material disclosed in patent document 4 is applied to a fastener chain as in conventional patent documents 1, 2 and 3, and a curable coating composition containing a polymerizable monomer is applied not only directly to a tape of the fastener chain but also to a fastener element, the fastener chain becomes hard after polymerization of the polymerizable monomer, and the flexibility required as a fastener chain is deteriorated.
The present invention has been made in consideration of the above-described circumstances inherent in a fastener chain and a slide fastener, and an object thereof is to provide a fastener chain and a slide fastener having both hydrophobicity and flexibility. The present invention relates to a special technology of chain and zipper.
The fastener chain of the present invention comprises: a pair of belts which are opposed in the width direction and made of fibers; a pair of element rows in an engaged state, which are respectively fixed to opposite side edge portions of the front and back surfaces of the pair of tapes; and an organic polymer and a non-fluorine-based hydrophobic component. The organic polymer and the non-fluorine-based hydrophobic component are attached to the pair of tapes in a state of entering the inside of the tapes from the front surface to the back surface of the tapes. The organic polymer and the non-fluorine-based hydrophobic component do not pass through the gap between the pair of tapes, and are not substantially attached to the element rows. In addition, substantially free of adhesion means that trace components that have been accidentally adhered in a manufacturing process different from the process of directly applying the element row are not included in the case where strict component analysis is performed. Whether or not the organic polymer and the non-fluorine-based hydrophobic component pass through the gap between the pair of tapes and adhere to the element rows is a matter that can be easily recognized by those skilled in the art by merely observing the condition of the front element row of the tape.
In addition, another fastener chain of the present invention includes: a pair of belts which are opposed in the width direction and made of fibers; a pair of element rows in an engaged state, which are respectively fixed to opposite side edge portions of the front and back surfaces of the pair of tapes; and an organic polymer and a non-fluorine-based hydrophobic component. On this basis, the organic polymer and the non-fluorine-based hydrophobic component are attached to the pair of tapes in a state of entering the inside of the tapes. The amount of the non-fluorine-based hydrophobic component attached to the element rows is less than 0.14% of the amount of the non-fluorine-based hydrophobic component attached to the tape. The amount of less than 0.14% also includes 0%, that is, the concept that the non-fluorine-based hydrophobic component is not attached to the element row at all.
In addition, another fastener chain of the present invention includes: a pair of belts which are opposed in the width direction and made of fibers; a pair of element rows in an engaged state, which are opposite side edge portions fixed to the opposite sides of the front and rear surfaces of the pair of tapes, respectively; and an organic polymer and a non-fluorine-based hydrophobic component. On this basis, the organic polymer and the non-fluorine-based hydrophobic component are attached to the pair of tapes in a state of entering the inside of the tapes. The amount of the organic polymer and the non-fluorine-based hydrophobic component attached to the tape was as follows: based on JIS-L-1096: in the softness test of method C (ring compression method) of 8.22.3 of 2010, the maximum load measured so that one of the tapes has a width of 16mm and a length in the longitudinal direction of the ring portion in the ring compression method is 80mm was set to 0.1N or less.
The following is an example, regardless of whether or not the organic polymer and the non-fluorine-based hydrophobic component are attached to the core rope.
That is, the organic polymer and the non-fluorine-based hydrophobic component are attached to the core string extending along the side edge portion of the tape along the thread line for fixing the pair of element rows to the tape.
Although there is no relation to how much of the non-fluorine-based hydrophobic component adheres to the front and back sides of the tape, it is expected to improve flexibility as described below.
That is, the amount of non-fluorine-based hydrophobic component attached is smaller on the reverse side than on the front side of the tape.
The following is an example, regardless of the amount of the product including the organic polymer and the non-fluorine-based hydrophobic component attached to the pair of tapes per unit surface area.
That is, the adhesion amount per unit surface area of the product including the organic polymer and the non-fluorine-based hydrophobic component to the pair of tapes is 9 to 22.5g/m 2 。
Further, whether or not the organic polymer and the non-fluorine-based hydrophobic component adhere to the pair of element rows as described above is not a matter of example.
That is, the organic polymer and the non-fluorine-based hydrophobic component are not only attached to the pair of tapes, but also attached to the tape-facing installation region in the front surface of the pair of fastener element rows, that is, the surface facing the tape side, in a state of being impregnated from the inside of the pair of tapes.
In addition, although it is not concerned with which surface of the tape the organic polymer and the non-fluorine-based hydrophobic component are attached, the following is an example.
That is, the organic polymer and the non-fluorine-based hydrophobic component are attached to the opposite surfaces of the pair of tapes.
As described above, although it is not related to whether or not an organic polymer and a non-fluorine-based hydrophobic component are attached to the pair of fastener elements, the following is an example.
That is, the organic polymer and the non-fluorine-based hydrophobic component are not attached to the pair of element rows.
The following is an example, regardless of whether the fastener chain includes a tape, a fastener element row, an organic polymer, and a non-fluorine-based hydrophobic component, and regardless of the detailed structure of the fastener element row.
That is, the fastener chain includes a core string extending along a side edge portion of the tape, and the element row is a monofilament extending in a longitudinal direction of the core string so as to be wound around the core string. In addition, the organic polymer and the non-fluorine-based hydrophobic component are not only attached to the pair of tapes and the pair of monofilaments, but also attached to the core rope in a state of being impregnated from the front surfaces of the pair of monofilaments.
Although there is no reference to the amount of the non-fluorine-based hydrophobic component attached to the core rope or the tape, the following is an example.
That is, the amount of non-fluorine-based hydrophobic component attached is smaller on the opposite side of the core rope than on the opposite side of the belt.
Although the type of the non-fluorine-based hydrophobic component is not particularly limited, the following is an example.
That is, the non-fluorine-based hydrophobic component is a silicone oil-based.
The present invention relates not only to a fastener chain but also to a slide fastener. That is, the slide fastener of the present invention includes the above-described fastener chain and a pair of slider elements attached to the fastener chain.
Effects of the invention
The invention relates to a technology for optimizing the hydrophobic treatment of a zipper chain and a zipper, and the zipper chain and the zipper have both hydrophobicity and softness.

Detailed Description
As shown in fig. 1 and 2, a slide fastener 1 according to a first embodiment of the present invention includes: a fastener chain 2 in a state in which the intermediate portion in the width direction is closed by engaging a pair of element rows 6; and a slider 3 for opening and closing the intermediate portion of the fastener chain 2 in the width direction in the longitudinal direction of the fastener chain 2. The slide fastener 1 according to the first embodiment of the present invention includes, in addition to the fastener chain 2 and the slider 3, a 1 st stopper 4A and a 2 nd stopper 4B that are fixed to both end portions in the longitudinal direction of the fastener chain 2 and determine the movement range of the slider 3. The slide fastener 1 according to the first embodiment has a "back side" specification in which the side on which the element row 6 is located is used for the back side.
The fastener chain 2 includes: a pair of belts 5 opposed in the width direction; a pair of element rows 6 in an engaged state, which are fixed to the pair of bands 5; a core rope 7 extending along opposite side edges of each of the tapes 5 and wound around the element rows 6; and a suture 8 that fixes the pair of element rows 6 to the strap 5.
The tape 5 is a woven or knit fabric. The yarn, which is a raw material of a woven fabric or knit fabric, bundles a plurality of fibers into one. The core rope 7 also bundles a plurality of fibers into one. The thread 8 is thinner than the core rope 7, and is formed by bundling a plurality of fibers into one. The tape 5 is not particularly limited as long as it can attach an organic polymer and a non-fluorine-based hydrophobic component, which will be described later, in an internal state. For example, the nonwoven fabric may be a nonwoven fabric having a gap in which an organic polymer and a non-fluorine-based hydrophobic component can enter the interior.
The pair of element rows 6 are fixed to one side of the pair of tapes 5 in the thickness direction while being engaged with the opposite side edges. The 1 st stopper 4A and the 2 nd stopper 4B are fixed to the tape 5 in a state of abutting against the element row 6 on both sides in the longitudinal direction of the fastener chain 2.
In the present embodiment, the 1 st stopper 4A is fixed to each belt 5. In the present embodiment, the 2 nd stopper 4B is fixed to the pair of belts 5 in a state where the pair of belts 5 are connected. Further, the 1 st stopper 4A and the 2 nd stopper 4B collide with the slider 3 to determine the movement range of the slider 3.
The pair of element rows 6 are fixed to the opposite side edges of the pair of strips 5. In addition, the pair of element rows 6 are engaged or disengaged according to the direction in which the slider 3 moves. When the slider 3 moves upward in fig. 1, the pair of element rows 6 are engaged, and when the slider 3 moves downward in fig. 1, the pair of element rows 6 are separated. Further, the slider 3 includes: a main body 3a movably attached to the pair of element rows 6; and a pull tab 3b coupled to the main body 3a and used for performing an operation. The pair of element rows 6 are engaged or disengaged by the movement of the main body 3 a.
The direction is determined in the following manner with reference to the state in which the slide fastener 1 is placed on the flat surface.
The front-rear direction is a direction in which the slider 3 is moved. The front-rear direction matches the longitudinal direction of the fastener chain 2. The front-rear direction coincides with the up-down direction in fig. 1.
The left-right direction coincides with the width direction of the fastener chain 2. The left-right direction coincides with the left-right direction in fig. 1 and 2.
The up-down direction coincides with the thickness direction of the fastener chain 2. The up-down direction coincides with the up-down direction in fig. 2. And, the lower front surface of the belt 5 is the front surface of the belt 5, and the upper front surface of the belt 5 is the reverse surface of the belt 5. The lower front surface of the element row 6 is the front surface of the element row 6, and the upper front surface of the element row 6 is the back surface of the element row 6. The pull tab 3b is disposed on the front side of the fastener chain 2.
The element row 6 is a monofilament. The monofilaments are made of synthetic resin and are linear. The monofilament is three-dimensionally curved in a coil-like or zigzag shape so as to be wound around the core rope 7 extending in a straight line. The monofilament may also be referred to as a coil element or a saw tooth element in correspondence with the curved shape. The portion of the monofilament that is engaged with and disengaged from each other per unit length is referred to as a fastener element 6a. Therefore, the monofilament has a structure in which a large number of fastener elements 6a are continuous in the longitudinal direction of the core rope 7. The elements 6a of the pair of element rows 6 are engaged with and separated from each other in accordance with the movement of the slider 3.
The element 6a includes: a lower leg 11 provided on the opposite side of the belt 5; an upper leg portion 12 facing the lower leg portion 11 at the upper side; an engagement head 13 that engages the upper leg 12 with the lower leg 11 on the other strap 5 side; and an engaging leg portion 14 that engages one of the upper leg portion 12 and the lower leg portion 11 with the adjacent fastener element 6a. As can be seen from fig. 3, the fastener element 6a is attached to the strap 5 such that the lower leg 11 is in contact with the strap 5 and the upper leg 12 is not in contact with the strap 5. That is, in the width direction of the fastener chain 2, the lower front face (front face) of the leg portion 11 is divided into a contact region with the tape 5 (a region 6c provided with respect to the tape 5 in the element row 6), and a region 6d on the side of the gap 5S of the pair of tapes 5. The gap 5S of the pair of belts 5 is a space portion formed between the pair of belts 5. The engagement head 13 engages with and disengages from the engagement head 13 of the other element 6a.
In the case of a coil element, as shown in the figure, the engagement leg portion 14 engages the upper leg portion 12 of the element 6a with the lower leg portion 11 of the adjacent element 6a.
In the case of the saw tooth element, although not shown, the element 6a at the midpoint of three front and rear adjacent elements 6a is joined to the upper leg 12 of the element 6a adjacent to the front side by the joining leg 14 extending from the upper leg 12 of the element 6a, and joined to the lower leg 11 of the element 6a at the midpoint by the joining leg 14 extending from the lower leg 11 of the element 6a adjacent to the rear side. The three teeth 6a adjacent to each other in the front-rear direction are saw teeth.
Organic polymer and non-fluorine-based hydrophobic component are attached to the front surfaces of the pair of fastener tapes 5 of the fastener chain 2. As a specific example of the organic polymer and the non-fluorine-based hydrophobic component, patent document 4 discloses. The organic polymer and the non-fluorine-based hydrophobic component contain an organic compound and are polymerized from a liquid curable coating composition containing a polymerizable monomer. More specifically, the liquid curable coating composition containing a polymerizable monomer, a non-fluorine-based hydrophobic component, and a heat-activated polymerization initiator is a substance that is chemically changed under predetermined conditions, the polymerizable monomer is polymerized, and the non-fluorine-based hydrophobic component is added to the organic polymer. Depending on the degree of polymerization, a non-fluorine-based hydrophobic component may not be added to the organic polymer. Examples of the non-fluorine-based hydrophobic component include silicone oil and hydrocarbon-based hydrophobic component, and silicone oil is preferably used. As an example of the silicone oil, a linear, branched or cyclic polysiloxane is exemplified, and a dimethylsiloxane is specifically exemplified. Examples of the hydrocarbon system include those in which the main chain is a urethane group and the side chain is a hydrocarbon group. Paraffin wax can be specifically mentioned. A specific example of the curable coating composition (hereinafter simply referred to as "coating composition") is EMPEL (trade name) sold by Green Theme Technologies, inc.
The coating composition is polymerized in the following steps 1) to 4) to impart hydrophobicity to the fastener chain.
1) The step (a) is a coating step of coating all the front surfaces of the fastener chain 2, that is, all the front surfaces of the pair of tapes 5, under non-polymerizable conditions. According to the coating conditions at this time, the coating composition does not pass through the gap 5S between the pair of tapes 5, and does not substantially adhere to the element rows 6. Depending on the coating conditions, the coating composition also passes through the gap 5S between the pair of tapes 5 and adheres to a part of the element rows 6. But the amount of the adhesive is very small. In the present invention, in either case, the element row is not directly coated with a hydrophobic component (coating composition) like the conventional hydrophobic slide fastener. In other words, the hydrophobic component (coating composition) is not directly coated from the reverse side (the side facing the opposite side to the tape 5) of the element rows 6.
2) The step (2) is an oxygen removal step of charging the coated fastener stringer 2 into a container under non-polymerizable conditions and removing oxygen from the container. The fastener chain 2 is put into the container in a roll shape (a state of being wound in a spiral shape).
3) The step (2) or the step (2) is followed by a pressurizing step of filling the container with a gas (for example, nitrogen gas) containing no oxygen and pressurizing the container to a predetermined gas pressure. The coating composition applied to the front surface of the fastener chain 2 passes through the pressurizing step and enters at least the inside of the tape 5. That is, the coating composition enters the inside of the tape 5 (gaps between fibers), and enters the inside of the core rope 7 (gaps between fibers) according to the coating conditions and the pressurizing conditions. The coating composition may also enter the core rope 7 through the thread 8 that fixes the pair of fastener element rows 6 to the tape 5. And then penetrates to the front surface of the element row 6 depending on the coating conditions and the pressurizing conditions. That is, the coating composition not only goes from the front side 5A to the back side 5B of the pair of tapes 5, but also goes to the front side of the element row 6 or goes to the inside of the core rope 7 (the gap between the fibers) through the lower leg 11 of the element row 6 depending on the coating conditions and the pressurizing conditions. In addition, depending on the coating conditions, the coating composition may pass through the gap 5S between the pair of element rows 6 and adhere to a part of the element rows 6 (generally, the region 6d on the gap 5S side in the front face), and therefore, in this case, the coating composition may also enter other parts of the element rows 6 and the core rope 7 through the pressurizing step. The amount of the coating composition to be applied per unit volume gradually decreases in accordance with the order in which the coating composition is introduced.
4) The step (a) is a heating step of heating the container while maintaining a pressurized state in the container. The thermoplastic polymerization initiator is activated by heating and the polymerizable monomer is polymerized, and the coating composition is finally attached to the fibers of the tape 5, the element rows 6, and the fibers of the core rope 7 as a product containing the organic polymer and the non-fluorine-based hydrophobic component. As described above, since the product contains the organic polymer and the non-fluorine-based hydrophobic component, whether or not the organic polymer and the non-fluorine-based hydrophobic component are attached to each member can be evaluated by extracting the non-fluorine-based hydrophobic component. Alternatively, the judgment can be made by observing the state of the front surface of each member. The difference in the amounts of the organic polymer and the non-fluorine-based hydrophobic component attached to the respective members can be evaluated by extracting the non-fluorine-based hydrophobic component and measuring the amounts thereof. Specifically, the evaluation can be performed by measuring the amount of silicone oil by a method described later. Assuming that the tape 5 is halved in the thickness direction, the adhesion amount of silicone oil per unit sample weight adhering to the tape 5 satisfies the inequality that the front side 5A of the tape 5 > the back side 5B of the tape 5. The amount of silicone oil attached to the tape 5 and the wick 7 per unit weight of sample satisfies the inequality that the front side 5A of the tape 5 > the back side 5B of the tape 5 > the wick 7. Further, since the element rows 6 are not fibers, silicone oil adheres to the outer front face of the element rows 6, not entering into gaps of the fibers like a tape. Therefore, the adhesion amount of the silicone oil adhering to the element rows 6 is not appropriately represented by the preceding inequality. The outer surface of the element row 6 includes the front and back surfaces of the element row 6.
As described in the above step 1), in the present invention, since the hydrophobic component is not directly applied to the element rows 6 as in the conventional hydrophobic slide fastener, the organic polymer and the non-fluorine-based hydrophobic component generated by directly applying the coating composition (water repellent) are not attached to the element rows 6 of the slide fastener obtained after the step 4). In other words, the organic polymer and the non-fluorine-based water repellent component, which are produced by directly applying the coating composition (water repellent) from the reverse side of the element row 6 (the side facing the opposite side of the element row 6 from the tape 5), are not adhered. The organic polymer and the non-fluorine-based hydrophobic component attached to the fastener element rows 6 are attached in a state of being impregnated from the inside of the pair of tapes 5 to the region 6c provided to the tapes 5, or the region 6d on the side of the gap 5S attached to the pair of tapes 5, or the organic polymer and the non-fluorine-based hydrophobic component generated when the back surface of the fastener chain 2 is wound into a roll shape in the steps 2) to 4) and the front surface of the tape 5 are brought into contact with each other, and the coating composition attached to the front surface of the tape 5 is attached to the back surface of the fastener element rows 6 in a very small amount, or is not attached at all.
When the coating composition does not pass through the gap 5S between the pair of tapes 5, the organic polymer and the non-fluorine-based hydrophobic component are not substantially attached to the fastener element rows 6. Substantially non-adhering means that, in the case of performing a strict component analysis, a trace component is not detected to such an extent that it is accidentally adhered in a manufacturing process different from the process of directly coating the element row 6. For example, the organic polymer and the non-fluorine-based hydrophobic component may be attached to the pair of tapes 5 in a state of entering the inside of the pair of tapes 5 from the front side to the back side of the pair of tapes 5, and may be attached to the front side of the fastener element rows 6 in a state of being impregnated from the inside of the tapes 5. In addition, there are cases where an organic polymer and a non-fluorine-based hydrophobic component are attached to the element row 6 via the thread 8, and where the hydrophobic component in the impregnated core rope 7 is also attached to the element row 6 via the thread 8. Whether or not the organic polymer and the non-fluorine-based hydrophobic component pass through the gap 5S between the pair of tapes 5 is a matter that can be easily recognized by those skilled in the art by merely observing the condition of the front surface of the tape 5 and the fastener element rows 6. Specifically, when the amount of the organic polymer and the non-fluorine-based hydrophobic component adhered to the front surface of the tape 5 is compared with the amount of the organic polymer and the non-fluorine-based hydrophobic component adhered to the front surface of the element row 6 in the region 6d on the side of the space 5S, that is, when the amount of the organic polymer and the non-fluorine-based hydrophobic component adhered per unit area is significantly larger than the amount of the organic polymer and the non-fluorine-based hydrophobic component adhered to the front surface of the tape 5 in the region 6d on the side of the space 5S on the front surface of the element row 6, it can be said that the coating composition is not applied to the element row 6 through the space 5S of the pair of tape 5, and that the organic polymer and the non-fluorine-based hydrophobic component are not substantially adhered to the region 6d in the element row 6 on the side of the space 5S of the pair of tape 5. In addition, when the composition is positively applied to the fastener element rows 6 so that the application composition passes through the gap 5S between the pair of tapes 5, there is a case where the fastener chain strength such as the push-up strength is lowered, and it can be determined whether or not the organic polymer and the non-fluorine-based hydrophobic component pass through the gap 5S between the pair of tapes 5 from the strength measurement of the fastener chain 2. Further, it is also possible to determine whether or not the gap 5S has been passed based on electron microscopic observation, XRF-WDX analysis, and mapping of non-fluorine-based hydrophobic components.
In addition, satisfying the above inequality means that the coating composition is applied to the front surface of the fastener chain 2 and the application amount is optimized. If the coating amount is large, the hydrophobicity as the fastener chain 2 is also high, but the fastener chain 2 becomes hard, and the standard of flexibility as the fastener 1 is not satisfied. Accordingly, the present inventors have found that the coating amount (the adhesion amount of the organic polymer and the non-fluorine-based hydrophobic component) of the coating composition was adjusted by the following softness test and hydrophobicity test.
For the test, as shown in table 1 below, four sample fastener stringers 2 having different coating amounts of the coating compositions were prepared.
[ Table 1 ]
The coating amount was calculated in the coating step per unit surface area of the belt 5 (unit: 1m 2 ) The coating amount of the coating composition of (a). Specifically, the tape 5 is applied to a surface area per unit (unit: 1 m) in a state of the fastener chain 2 2 ) The amount of the coating composition in the range of (a). Since the fastener chain 2 having the element row 6 and the core rope 7 are present in addition to the tape 5 in the range of the unit surface area of the tape 5, the applied coating composition is not only adhered to the tape 5Also attached to the element row 6 and the core rope 7 existing in this range. The term "surface area" means the surface coated with the coating composition. In the hydrophobicity test, these four fastener stringers were used as samples as they are, and in the flexibility test, these four fastener stringers were decomposed, the element row 6 was detached from one tape 5 of the fastener stringers 2, and this one tape 5 was used as a sample.
The softness test is a method based on the C method (ring compression method) of 8.22.3 of JIS-L-1096:2010.
As shown in fig. 4, the outline of the softness test of this method is as follows: the belt 5 is overlapped at both ends in the longitudinal direction thereof, both ends in the longitudinal direction of the belt 5 are set as the sandwiching amount portion 21, and the middle portion in the longitudinal direction is set as the ring portion 22 pressed by the pressing head 32, the sandwiching amount portion 21 arranged under the ring portion 22 in the standing state is sandwiched by the sandwiching portion 31, the pressing head 32 is reciprocated in the up-down direction with respect to the ring portion 22, and the load applied to the pressing head 32 during reciprocation thereof is measured. As described in more detail below.
The test device used in the softness test includes: a clamping part 31 for clamping the object to be measured; a moving member 33 that moves up and down just above the clamp portion 31; a load cell 34 fixed directly below the moving member 33; and a pressurizing head 32 fixed directly below the load cell 34 and pressurizing the object to be measured of the fastener chain 2. The load applied to the pressurizing head 32 is converted into an electric signal proportional to the load by the load cell 34, and the load is measured from the electric signal.
The sample tape 5 used in the flexibility test is described in detail below. The sample tape 5 is a tape obtained by removing the fastener element rows 6 from the one-sided tape 5 of the fastener chain 2, and the width of the one-sided tape 5 is set to 16mm. The length of the belt 5 is 120mm or more. The middle portion in the longitudinal direction of the belt 5 is a portion for pressing the ring portion 22 of the pressing head 32, and the dimension in the longitudinal direction is 80mm. The two ends of the belt 5 in the longitudinal direction are located on both sides of the loop 22, and are portions to be the clamping amount portions 21 to be clamped by the clamping portions 31 of the flexibility test device, and the dimensions in the longitudinal direction are set to 20mm or more, respectively. Further, marks are provided at both ends of the ring 22, that is, at the boundary positions between the clamping amount portion 21 and the ring 22.
The belt 5 is folded, and the sandwiching portions 21 are formed by overlapping both end portions in the longitudinal direction of the belt 5, and the intermediate portion in the longitudinal direction is formed as an annular ring portion 22 pressed by the pressing head 32. In order to maintain the state where the clamping amounts 21 overlap, for example, the belt 5 is fixed so as to present a state where the clamping amounts 21 overlap.
The posture of the belt 5 is set so that the ring 22 is positioned right above the clamping portion 21, and the clamping portion 21 is clamped by the clamping portion 31. At this time, the mark coincides with the upper end of the clamp portion 31. The interval between the pressing head 32 and the upper end of the clamp 31 was set to 40mm. Thus, the pressurizing head 32 is disposed with a gap right above the ring 22. The pressing head 32 was reciprocated up and down at a movement speed of 50mm/min and a movement amount of 25 mm. The number of reciprocations was 5. The maximum load (unit N) applied to the pressurizing head at each time was measured, and the average value of the maximum load for all times was shown as the result in table 1. The maximum load is a value obtained by rounding the value of the 4 th bit after the decimal point.
According to the test results in Table 1, the coating weight was 9.0g/m 2 Example 1, coating weight 22.5g/m 2 The softness test values of example 2 were all 0.1N or less, and it was determined that softness was appropriate. On the other hand, the coating weight was 45.0g/m 2 Comparative example 1 of (B) with a coating weight of 75.0g/m 2 Since comparative example 2 of (a) was greater than 0.1N, it was judged that flexibility was not appropriate.
The hydrophobicity test is a jet test based on JIS-L-1092. As shown in fig. 5, the outline of the spray test was that 250mL of water was spread on the fastener chain 2 from the hopper 41 for 25 to 30 seconds, and then the water drops adhering to the fastener chain 2 were scraped off by indirectly applying an impact to the fastener chain 2, and the hydrophobicity of the fastener chain 2 was evaluated. As described in more detail below.
1) A circular jig 44 having a diameter of 150mm was prepared.
The jig 44 includes: a circular inner frame 45; a C-shaped outer frame 46 surrounding the outer periphery of the inner frame 45 in a range slightly shorter than the entire periphery of the outer periphery of the inner frame 45; fasteners 47 fixed to both ends of the outer frame 46; and a pair of holding portions 48 protruding from the outer frame 46 at two positions separated by about 1/4 of a circumference from the position of the fastener 47 along the outer side Zhou Shun of the outer frame 46.
The fastener chain 2 for sample is disposed on one side of the jig 44 while being kept in a state of passing through the center of the circular shape of the jig 44 in a state of extending straight without being creased, and both ends of the fastener chain 2 are inserted between the outer frame 46 and the inner frame 45, and the fastener 47 is closed to fix both ends to the jig 44. The portion of the fastener chain 2 protruding from the jig 44 is cut out.
2) 250mL of water was placed in the funnel 41, and it was confirmed that the dispensing was completed within 25 to 30 seconds after the start of the dispensing. A spray nozzle 42 is attached to the front end of the funnel 41, and water is discharged radially from a large number of holes of the spray nozzle 42.
3) The jig 44 to which the fastener chain 2 is attached is placed on a table 51 having a slope inclined at an angle of 45 degrees with respect to the horizontal plane. With the front side of the fastener chain 2 facing upward. In addition, when the table 51 is viewed from directly above, the direction of the jig 44 is such that the traveling direction of the water flowing on the inclined surface of the table 51 is parallel to the fastener chain 2 extending in a straight line. The distance L between the center of the tip of the spray nozzle 42 and the center of the jig 44 in the up-down direction was set to 150mm.
4) 250mL of water was placed in the funnel 41, and the water was spread on the fastener chain 2 for 25 to 30 seconds.
5) The grip portion 48 on the grip side is removed from the upper side of the table 51, the fastener chain 2 is turned upside down, and the grip portion 48 on the opposite side to the grip portion 48 is gently collided with a hard object once to drop water. Then, the grip portion 48 that hits the hard object is gripped, and the grip portion on the opposite side is gently collided with the hard object once, so that the water drops. After the above treatment, the grade was evaluated in accordance with the following criteria in JIS-L-1092. From the viewpoint of quality required in normal use of the slide fastener 1, 3 or more stages are acceptable.
Stage 1: the front surface as a whole is moist.
2 stages: the front half of the front surface is wet and is in the state of each small wet-soaked cloth.
3 stages: the front surface presents wetting of individual small water droplets.
4 stages: the front side was not wetted and exhibited small water droplet adhesion.
5 stages: the front surface is not wet and no water drops are attached.
The slide fastener chain 2 for sample was washed 50 times and 100 times with JIS-L-1930C 4M. From the results shown in table 1, the washing durability after washing 50 times and 100 times was 3 in each of examples 1 and 2, and 4 in each of comparative examples 1 and 2, and the water repellency quality of 3 or more was satisfied.
Examples 1 and 2 were obtained according to the results of the softness test and the hydrophobicity test, and both of the washing durability and the softness were obtained. Regarding the samples of examples, the ratio of the average adhesion amount of silicone oil to each member was as follows.
The amount of silicone oil adhering to each of the element rows 6 and the core rope 7 is smaller than the amount of silicone oil adhering to the tape 5 in terms of weight ratio. The results are also estimated from the fact that the tape 5, not the element row 6 and the core rope 7, is directly coated with the coating composition of the organic polymer and the non-fluorine-based hydrophobic component (silicone oil) as described above. The amount of silicone oil adhering to the element rows 6 is extremely small and is less than 0.14% of the amount of silicone oil adhering to the tape 5 in terms of weight ratio. That is, when the amount of adhesion of the silicone oil to the tape 5 (the ratio of the weight of the silicone oil to the weight of the tape 5 added to the weight of the silicone oil: wt%) is set to 100%, the ratio of the amount of adhesion of the silicone oil to the element row 6 (the ratio of the weight of the silicone oil to the weight of the element row 6 added to the weight of the silicone oil: wt%) is lower than 0.14%. In addition, the amount of organic polymer attached to the wick 7 is less than 17% of the amount of organic polymer attached to the belt 5 by weight. That is, when the amount of adhesion of the silicone oil to the tape 5 (the ratio of the weight of the silicone oil to the weight obtained by adding the weight of the tape 5 to the weight of the silicone oil: wt%) is set to 100%, the ratio of the amount of adhesion of the silicone oil to the wick 7 (the ratio of the weight of the silicone oil to the weight obtained by adding the weight of the wick 7 to the weight of the silicone oil: wt%) is lower than 17%.
The difference in the amount of the hydrophobic component adhered to each member can be evaluated based on the amount of the silicone oil adhered, and the amount of the silicone oil adhered can be measured as follows. The respective samples of the tape 5, the element row 6 and the core rope 7, each having the organic polymer and the non-fluorine-based hydrophobic component (silicone oil) attached thereto, were measured at about 10g, and subjected to Soxhlet extraction with hexane for two hours. After the extract was dried and solidified, IR measurement was performed, and as a result, it was confirmed that the main component of the extract was silicone oil. The IR measurement is performed by an infrared spectroscopic method, and this time, the ATR method is used. Thus, the amount of the extract containing silicone oil as a main component attached to each sample was calculated.
The coating amount of the coating composition per unit surface area of the tape 5 can be calculated from the weight difference between the fastener chain before the coating composition is applied and the fastener chain after the coating composition is applied. The weight of the fastener chain after the application of the coating composition is substantially the same as the weight of the fastener chain after the chemical change of the coating composition into the polymerized product, that is, the weight of the fastener chain to which the polymerized product is attached.
The present invention is not limited to the above-described embodiments, and can be appropriately modified within a range not departing from the gist thereof.
