DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hook and loop mixed surface fastener, and more particularly to a hook and loop in which hook-shaped engaging elements and loop-shaped engaging elements having different heights are arranged adjacent to one surface of a base cloth. It relates to a mixed type surface fastener.

[0002]

2. Description of the Related Art Conventionally, a hook-and-loop fastener marketed under the trade name "Maji-Touch" has a male surface provided with a large number of hook-shaped engaging elements made of a resin molded body having an enlarged head on one surface of a base cloth. It is composed of a fastener and a female surface fastener provided with a large number of loop-shaped engaging elements. By engaging these two engaging elements, the two surface fasteners can be tightly integrated with each other.

However, since the conventional male fastener and female fastener use two types of surface fasteners, it is necessary to work while distinguishing the two types of surface fasteners, for example, when attaching them to clothing or the like. Also, if a male fastener is mistakenly attached to the part where the female fastener is attached, the male fasteners cannot adhere to each other, so remove one of the male fasteners and replace it with a female fastener. There is a need. However, if the male surface fastener is adhered to a garment or the like with a hot melt adhesive or the like, the replacement is substantially impossible. In the case of sewing with a sewing machine or the like, it is possible to replace the sewing machine, but it is a time-consuming operation.

In contrast to the method using two kinds of hook-and-loop fasteners, a hook-shaped engaging element and a loop-shaped engaging element made of a resin molded body having an enlarged portion on one surface of a base cloth are mixed. A hook and loop mixed type hook-and-loop fastener provided has been proposed (see JP-A-49-33745). In such a hook-and-loop fastener, a hook-shaped engaging element and a loop-shaped engaging element are provided on one surface of the base cloth in a mixed manner, so that one type of hook-and-loop fastener can be closely adhered to and integrated with each other. It can be peeled and separated.

[0005]

The hook and loop mixed type hook-and-loop fastener has an excellent feature that one type of hook-and-loop fastener can be closely adhered to and integrated with one another. Because the height of the hook-shaped engagement element is set higher than the height of the loop-shaped engagement element,
When the hook-and-loop fasteners are not tightly integrated with each other,
The hook-shaped engaging element engages with a fiber product made of a nonwoven fabric, a knitted fabric, a nap blanket, a thin woven fabric, or the like to damage the fiber product and sometimes attaches dust such as lint. Further, since the surface of the hook-and-loop fastener is rough, it has the drawback of the male hook-and-loop fastener as it has an inferior feel when attached to clothes or the like.

Further, the hook-and-loop mixed type surface fastener may be formed because the density of the hook-shaped engaging elements and the loop-shaped engaging elements provided on one surface of the base cloth is low and the ratio of the hook-shaped engaging elements is extremely low. Tensile strength and peeling strength (hereinafter referred to as "engagement strength") when they are brought into close contact with each other are remarkably inferior to those when the male and female fasteners are brought into close contact with each other. There was a disadvantage that there was no. For this reason, a practical hook / loop mixed type hook-and-loop fastener has not yet been commercialized.

Therefore, an object of the present invention is to make the engaging strength, which is a drawback of the conventional hook and loop mixed type surface fastener, equal to or practically equivalent to the conventional male / female type surface fastener. An object of the present invention is to provide a hook-and-loop mixed type hook-and-loop fastener with high practicality which has solved the drawbacks of the conventional male hook-and-loop fastener. Another object of the present invention is to provide a method for efficiently manufacturing the hook and loop mixed surface fastener.

[0008]

The present inventor has studied the conventional hook and loop mixed type surface fastener from the viewpoint of manufacturing technology. Since there is a risk that adjacent loop-shaped engaging elements may be damaged when implanting, the density of hooks and loops is reduced, and the ratio of hook-shaped engaging elements is reduced as much as possible. Presuming that the joining element had to be set extremely higher than the loop-shaped engaging element, manufacturing hook-and-loop mixed surface fasteners that would not damage adjacent loop-shaped engaging elements After examining the method, surprisingly, if the hook-shaped engaging element is set lower than the loop-shaped engaging element, the hook-shaped engaging element can be implanted without damaging the loop-shaped engaging element. It was also found that the density of the hook and the loop could be increased, the ratio of the hook-shaped engagement elements could be increased, and an improvement in the engagement strength could be expected. Things.

That is, according to the first aspect of the present invention, the hook-shaped engaging element and the loop-shaped engaging element, which are formed of a molded body having an enlarged head at the tip, are provided on one surface of the base cloth. A hook and loop mixed surface fastener, comprising a hook-shaped engaging element having a height of 0.5 to 4.0 mm on one surface of the base cloth and a height of 0.7 to 2.0 mm higher than the hook-shaped engaging element. 4.2mm
With a loop-shaped engagement element of 40 to 150 pieces / cm ↑ 2,
A hook-and-loop mixed type surface fastener is provided so that the ratio of the loop-shaped engaging elements is 30 to 60%.

According to a second aspect of the present invention, at least one row of at least one hook-shaped engaging element row formed of a molded body having a height of 0.5 to 4.0 mm and having a bulging portion at one end is formed on one surface of the base cloth. After planting, adjacent to the row of hook-shaped engaging elements, the composite yarn of synthetic fiber is set to 0.2 to 2.0 m higher than the height of the hook-shaped engaging elements.
A method for manufacturing a hook and loop mixed-type hook-and-loop fastener , characterized in that at least one loop row is provided by forming the loop into a m-high circular loop.

Further, according to a third aspect of the present invention, a single thread of synthetic fiber is formed in a circular loop on one surface of the base cloth, and at least one loop row is provided in a plurality of loops. Adjacently, forming a composite yarn of a synthetic fiber into a circular loop, providing at least one loop row, cutting the top of the circular loop formed of a single yarn of the synthetic fiber, and then formed by melting the top of the single yarn is the cutting in the pressurized heat unit, 0.2 to 2.0 mm less than the circular loop consisting doubling of synthetic fiber, a molded body having a膨頭portion height 0.5~4.0mm This is a method of manufacturing a hook and loop mixed type hook-and-loop fastener.

[0012]

According to the present invention, since the hook-shaped engaging element and the loop-shaped engaging element are provided on one surface of the base cloth, the hook-and-loop fasteners having the same structure can be tightly integrated with each other or separated by peeling. can do. Moreover, since the height of the loop-shaped engaging element is set higher than that of the hook-shaped engaging element, the density of the hook-shaped engaging element and the loop-shaped engaging element can be increased. Therefore, the hook-and-loop mixed type surface fastener of the present invention has the same engagement strength as the conventional male fastener and female surface fastener when used. In addition, since the loop-shaped engaging element is set higher than the hook-shaped engaging element, the feel of the surface is excellent, and the hook-shaped engaging element is locked by other textiles, for example, during washing, and is damaged. There is an advantage that there is no fouling or adhesion of lint.

According to the method for manufacturing a hook and loop mixed type hook-and-loop fastener of the present invention, at least one loop row and a loop-shaped engaging element row forming a hook-shaped engaging element are formed on one surface of the base cloth. Since at least one loop row to be formed is provided in a plurality of rows and the height of the latter loop row is set higher than that of the former loop row, the loop-shaped engaging element can be easily woven into the base cloth.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of an embodiment of a hook and loop mixed surface fastener according to the present invention. FIG. 1 is a perspective view of a hook-and-loop mixed type surface fastener according to the present invention. The surface fastener 1 has a hook-shaped engaging element on one surface of a base cloth 2 made of a woven cloth, a knitted cloth, a plastic sheet or the like. 3 and a loop-shaped engagement element 4 are provided. The base fabric made of a woven fabric or a knitted fabric usually has a thickness of 0.3 to 3.0 mm. The hook-shaped engaging elements 3 and the loop-shaped engaging elements 4 are provided in a row on the base cloth 2 as shown in FIG. The engaging elements 3 and 4 are provided alternately every one row or every three or four rows. However, the hook-shaped engaging elements 3 are formed from the viewpoint of ease of implantation of the resin molded body when the hook-shaped engaging elements 3 are formed. 3 is
Usually, it is preferable to provide every two rows. The arrangement of the hook-shaped engagement elements 3 and the loop-shaped engagement elements 4 may be, for example, a parallel arrangement along the longitudinal direction of the base cloth, a staggered arrangement, in addition to the parallel arrangement at an angle in the longitudinal direction of the base cloth shown in FIG. Various arrangements such as a zigzag arrangement, every other or every two staggered arrangements, and a cyclic arrangement can be employed. Usually, a parallel arrangement along the longitudinal direction of the base fabric is preferable because it is easy to manufacture.

When at least one hook-shaped engagement element row and loop-shaped engagement element row are alternately arranged as described above, the hook-shaped engagement element 3 and the loop-shaped engagement element 4 provided on the base cloth are provided.
Ratio is equal, it is desirable to be able to maximize the engagement strength when the surface fasteners of the present invention are tightly integrated with each other, but in order to improve the commercial value of the surface fasteners, both ends of the base fabric There may be a case where a row of hook-shaped engaging elements is arranged in the portion, or a row of loop-shaped engaging elements is arranged.
In consideration of such arrangement of the engaging elements, the ratio of the hook-shaped engaging elements or the loop-shaped engaging elements is 30 to 60%. If it is within the above range, there is no reduction in the engagement strength when the two surface fasteners are closely adhered to each other, but if it is outside the above range, the balance with the mating surface fastener to be engaged will be lost. When the hook-and-loop fasteners are closely integrated with each other, the strength of engagement is greatly reduced, which is not practical.

The height of the loop-shaped engaging element 4 provided on one surface of the base cloth 2 is suitably 0.7 to 4.2 mm, and usually 1 to 3 mm. If the height of the loop-shaped engaging element is less than 0.5 mm, it is difficult to lock the loop-shaped engaging element to the hook-shaped engaging element 3 on the other side, and it is impossible to obtain a practical engaging strength. On the other hand, if the height of the loop-shaped engaging element exceeds 4 mm, the engagement is likely to be released even when engaging with the hook-shaped engaging element on the other side.

The height of the hook-shaped engaging element 3 provided on one surface of the base cloth 2 is 0.5 to 4.0 mm, usually 1.5 to 2.5 mm.
It is. If the height of the hook-shaped engaging element 3 is 0.5 mm or less, it is difficult to engage with the loop-shaped engaging element on the other side.

Hook-shaped engaging element 3 and loop-shaped engaging element 4
The relationship between the heights of the loop-shaped engagement elements 4 as shown in FIG.
Is set higher than the hook-shaped engagement element 3. The difference in height is suitably 0.2 to 2.0 mm, usually 0.3 to 1.0 mm.
If the difference in height is less than 0.2 mm, the surface of the hook-and-loop fastener may be rough due to the influence of the hook-shaped engaging element, resulting in a poor feel when attached to clothes, and the hook-shaped engaging element may engage with other textiles. Or lint may adhere. On the other hand, if it exceeds 2.0 mm, it becomes difficult to engage with the hook-and-loop fastener of the other party due to the rebound of the loop-shaped engaging element, and even if it is engaged with the hook-and-loop fastener of the other party, the two hook-and-loop fasteners adhere to each other It is difficult to integrate them.

The height of the hook-shaped engaging element is 0.5 to 4.0 mm
By setting the hook engagement element 3 and the loop engagement element 4 on one surface of the base cloth, the density can be increased. In the present invention, 40 to 150 hook-shaped engagement elements and loop-shaped engagement elements are provided per 1 cm @ 2. The number of such engaging elements depends on the shape of the resin molded body forming the hook-shaped engaging elements and the diameter and the number of the yarns forming the loop-shaped engaging elements, but usually 60 to 120 engaging elements are provided. Is preferred. If the sum of the two engaging elements is less than 40 per cm 2, the engaging strength when the surface fasteners are closely adhered to each other is inferior, and it is difficult to say that the surface fastener is a practical surface fastener. If the sum of the two engaging elements exceeds 150, it is difficult to plant a resin molded body on the base cloth.

The resin molded body having a bulge used as the hook-shaped engaging element has a known shape such as a mushroom shape or an umbrella shape. Usually, a mushroom-like shape is preferably employed. In the case of adopting a mushroom-like shape, a molded body having a ratio (D / W) of the long side W of the support portion to the long side D of the bulging portion of 1.5 to 3.5 as shown in FIG. It is preferably used.

The loop-shaped engaging element has a diameter of 20 to 100.
μ, usually 35 to 95 μ in diameter, is used as a composite yarn in which single yarns of synthetic fibers are combined. The plying yarn is 2 to 50 single yarns, usually 3
~ 30 single yarns are used in combination.

Synthetic fibers and metal fibers are used as the thread forming the loop-shaped engaging element. Usually, fibers made of a thermoplastic synthetic resin such as polyamide, polyester, polypropylene, and polyethylene are used. In particular, polyester is preferably used because of its high engaging strength and excellent dimensional stability. A thermoplastic synthetic resin such as polyamide or polypropylene is used as the resin molded body forming the hook-shaped engagement element.

The same thermoplastic synthetic resin is usually used for the resin molded body constituting the hook-shaped engaging element and the synthetic fiber constituting the loop-shaped engaging element. Alternatively, a different resin may be used. In this case, it is preferable to use a resin having a larger Young's modulus than the resin used for the loop-shaped engagement element, as the resin used for the hook-shaped engagement element, in order to improve the engagement strength. For example, a molded body made of a resin such as polyester for the hook-shaped engagement element,
Synthetic fibers made of a resin such as polyamide can be used for the loop-shaped engagement element.

A resin molded body having a bulging portion constituting a hook-shaped engaging element is planted on a base cloth. When a single yarn of synthetic fiber is used for the resin molded body, the single yarn is woven in a row in two base fabrics by a binding double weaving method, and the single yarn is cut between the base fabrics. Is heated to form a bulging portion, or a loop forming a hook-shaped engaging element and a loop-shaped engaging element is woven into a base cloth at the same time, and then the top of the loop for the hook-shaped engaging element is cut. The tip of the cut top can then be overheated and fused to form a bulge.

On the other surface of the base fabric 2 constituting the hook and loop mixed type hook-and-loop fastener 1, an adhesive material is usually applied to the entire surface or a part thereof, and the adhesive layer 5 is formed by the adhesive material. I have. On the surface of the adhesive layer 5, a protective sheet 6 that can be peeled off from the adhesive layer is attached. hook·
In the case of using a loop-type hook-and-loop fastener, the hook-and-loop fastener 1 can be easily attached by peeling the protective sheet 6 from the adhesive layer 5, and workability can be improved. A hook-and-loop fastener having no adhesive layer on the other surface of the base fabric 2 can be attached to clothing or the like with a sewing thread or the like.

FIGS. 3 to 5 are perspective views showing an example of use of the hook and loop mixed surface fastener of the present invention. FIG. 3 shows two hook and loop mixed surfaces of the same structure according to the present invention. The fasteners 1 and 1 'are integrated with each other in close contact with each other. In this case, the hook-shaped engaging element 3 provided on the one surface fastener 1 is engaged with the loop-shaped engaging element 4 'provided on the mating surface fastener 1'. The loop-shaped engaging element 4 is engaged with a hook-shaped engaging element 3 'provided on the mating surface fastener 1'.

The hook and loop mixed surface fastener of the present invention has a tensile strength of 1.26 kg / cm / 2 or more and a peel strength of 1 or more when two surface fasteners having the same structure are brought into close contact with each other.
A surface fastener of 76 g / cm or more is preferably used. The above tensile strength and peel strength are values measured according to the measuring method described in JIS L3416.

FIG. 4 shows an example in which the hook-and-loop mixed type surface fastener 1 of the present invention and the conventional male surface fastener 7 are tightly integrated, and the hook-shaped engaging element 9 provided on the male surface fastener 7 has a hook. -It is engaged with the loop-shaped engaging element 4 provided on the loop mixed surface fastener. FIG. 5 shows an example in which the hook-and-loop mixed type surface fastener 1 and the conventional female surface fastener 8 are tightly integrated.
Is engaged with the hook-shaped engaging element 3 provided on the hook-and-loop mixed type surface fastener. While hook and loop mixed type surface fastener of the present invention may also be engaged with a conventional male or Mesmin fastener as shown in FIG. 4 and FIG. 5, the engagement strength is hook and loop mixed forms of the present invention 2 hook-and-loop fasteners
It is lower than when the sheets are engaged with each other.

First, as shown in FIG. 6 two base fabrics 21,
The 21's are superposed at appropriate intervals, and the single yarns 22 are woven in a row by the binding double weaving method. Then by cutting the single yarn woven two base fabric between the base fabric, as shown in FIG. 7, single yarns 22 to one surface of the base fabric is protruded in a row 2
The base cloths 21, 21 'are obtained. Then, a heating means such as a heating plate heated to, for example, 500 to 600 ° C. is brought into contact with the top of the single yarn 22 to melt the top and form a mushroom-shaped bulge, and a height of 0.5 to 4.0 m. Form hook-shaped engagement elements. An arbitrary shape can be obtained for the shape of the bulging portion by appropriately selecting the heating temperature and the heating time. Next, between the hook-shaped engaging element rows woven into the rows, a loop-shaped engaging element row composed of a circular loop made of synthetic yarn of 0.2 to 2.0 mm higher than the hook-shaped engaging elements. By forming, a hook-and-loop mixed surface fastener comprising a hook-shaped engaging element and a loop-shaped engaging element formed of a molded body having a bulge at the tip can be obtained.
