Description

  The present invention relates to a textile product provided with a hook-and-loop fastener as an engaging member, and more particularly, a loop hook-and-loop fastener is attached to the textile product body, and the loop hook-and-loop fastener is provided via a separately prepared double-side hook hook-and-loop fastener. It is related with the textile product with the hooked surface fastener.

Hook fasteners with hook-like engagement elements that use hook and loop fasteners known as Velcro (trade name) and Velcro (trade name) as locking members used in diaper covers for children and adults And a loop surface fastener having a loop-like engaging element are used. It is recognized as an advantage that the hook-and-loop fastener is flexible and can be easily attached to a diaper cover or the like, and can be easily engaged and detached.
However, the hook hook-and-loop fastener attached to the diaper cover when washing the diaper cover engages with other fibers, damages the other fibers, and the hook hook-and-loop fastener itself takes in lint or hook-like fasteners. There is a problem that the combined element itself is damaged and the engaging force is reduced.
To solve this problem, the hook-and-loop fastener member is composed of a loop hook-and-loop fastener portion and a hook hook-and-loop fastener portion, and when the hook hook-and-loop fastener is not used, the hook hook-and-loop fastener portion is engaged with the loop hook-and-loop fastener portion to A structure that does not expose the hook-and-loop fastener has been proposed. (See Patent Document 1)

  The hook hook-and-loop fastener of the diaper cover described in Patent Document 1 is folded in half to engage the hook hook-and-loop fastener and the loop hook-and-loop fastener to prevent the hook hook-and-loop fastener from being exposed. If it is forgotten or the engagement is insufficient, the engagement is released and the hook surface fastener is exposed. In particular, during washing, a force is applied to the engaging portion by a water flow or other laundry, so there is a high possibility that the engagement is disengaged.

  An object of the present invention is to provide a textile product with a hook-and-loop fastener that completely solves the problem of damaging other textile products during washing. In addition, the present invention completely solves the problems of hook hook fasteners of hook fasteners attached to diaper covers in particular, and an object thereof is to improve the durability of the diaper cover.

  That is, the present invention provides a hook surface fastener having a loop surface fastener at a predetermined portion of a textile product to be engaged and having hook-like engagement elements on both sides between the two loop surface fasteners of the portion to be engaged. And a hook-and-loop fastener that can be removed from the textile product as needed. It is a textile product.

According to the present invention, it is a problem in diaper covers, linen products, clothing, etc., product damage due to a series of washing processes, reduction in engagement force due to breakage of hook-and-loop fastener, fiber waste entangled in the hook, etc., and durability of the product The improvement of convenience, improvement of convenience and hygiene, and reduction of lint removal work can be realized, and a textile product with a hook-and-loop fastener that can be applied to general clothing, other special clothing, and other textile products in general can be obtained.
Moreover, the textile product with a hook-and-loop fastener of this invention is used suitably especially for a diaper cover. Only flexible loop hook-and-loop fasteners are attached to the diaper cover, so there is no trouble of hook hook-and-loop fasteners engaging with other textile products when attaching to the human body, and the double-side hook surface Engagement with the fastener in between is easy and reliable. Further, when washing the diaper cover, the problem of the hook hook-and-loop fastener attached to the diaper cover is completely solved simply by peeling the engagement surface and removing the double-side hook hook-and-loop fastener.

The loop surface fastener and the double-sided hook surface fastener used in the present invention can be used without particular limitation as long as they have surface engaging elements.
The loop surface fastener may be a pile specification made of knitted fabric in which loop-like engagement elements are erected on a base fabric, a non-woven fabric, a brushed woven fabric, a knitted fabric, or the like that engages with the hook surface fastener. There is no particular limitation. In particular, as a loop surface fastener attached to the diaper cover, a nap specification, that is, a brushed knitted fabric is preferable in terms of engagement, flexibility, and cost.

On the other hand, as double-side hook hook-and-loop fasteners, hooked engagement elements such as hooks and mushrooms are erected on both sides of a knitted and woven base fabric, or molded from synthetic resins such as polyethylene, polypropylene, and polyester. A hook-like engagement element such as a hook, mushroom, arrowhead, or table type can be used on both sides of the substrate.
Since the double-sided hook surface fastener used for the diaper cover is not normally expected to be used many times, a thin and low-cost one is preferable. From this point, a resin-molded hook surface fastener is preferably used. As a specific example, the hook-shaped engagement elements are erected on both sides of the substrate by using a technique in which molten resin is press-fitted onto a roller having a large number of micro holes and the hook-shaped engagement elements are integrally formed on the substrate. Examples include hook-and-loop fasteners.
Also, the molten resin is extruded through a die shaped to form a plurality of rows of ridges on the substrate and its surface, the ridges are cut laterally at small intervals, and then the substrate is stretched to form a continuous row. A hook-and-loop fastener in which hook-like engagement elements are erected on both surfaces of a substrate by using a technique for forming a large number of hook-like engagement elements from the ridges of the stripes can be mentioned.
By applying the above technique and appropriately setting the thickness of the substrate and the size of the hook-like engagement element, a double-side hook hook-and-loop fastener suitable for the purpose of the present invention can be easily manufactured.

The resin constituting the double-side hook hook-and-loop fastener is not particularly limited as long as it is a thermoplastic resin, and includes polyethylene, polypropylene, polyamide, polyester, and the like. In consideration of the fact that the hook surface fastener is discarded, when the water-soluble resin is used, the hook surface fastener can be put into a washing machine without being removed before washing, and the hook surface fastener is being washed. It is preferable because it is dissolved in Moreover, if it is an easily decomposable resin, the burden of a disposal process can be reduced.
Specific examples of the water-soluble resin include water-soluble polyvinyl alcohol polymers and water-soluble polyacrylic acid polymers. Examples of the easily degradable polymer include a microbial degradable polymer and a material that generates a small amount of heat and does not generate harmful gases during combustion, and a polylactic acid-based polymer, a modified starch-based polymer, and the like are preferably used.

Hereinafter, the example which applied the textiles with a hook_and_loop | surface fastener of this invention to the diaper cover is demonstrated concretely using drawing.
FIG. 1 is a developed plan view showing an example of a diaper cover to which the fiber product with a hook-and-loop fastener of the present invention is applied.
The diaper cover has a substantially T shape in which the body portion 1 and the crotch portion 2 are connected to each other, and is formed of a waterproof fabric including a plastic sheet or the like. In addition, FIG. 1 has shown the inner side (human body contact side) of a diaper cover.
Loop surface fasteners 3 and 3 ′ are attached to both end portions on the surface side (outer side) of the body portion 1, and loop surface fasteners 4 are attached to the inside of the lower portion of the crotch portion 2.

FIG. 2 is a schematic plan view showing a shape when the diaper cover shown in FIG. 1 is used.
As shown in FIG. 2, the both ends of the trunk | drum 1 are bend | folded inside, and it engages with the double-sided hook hook-and-loop fastener 5 prepared separately so that it may connect with the loop hook-and-loop fasteners 3 and 3 'of the trunk | drum surface. Next, the crotch part 2 is stacked on the body bending part, and the double-side hook surface fastener 5 and the loop surface fastener 4 inside the crotch part are engaged to fix the shapes of the body part 1 and the crotch part 2. That is, the diaper cover shown in FIG. 1 has only loop hook-and-loop fasteners, and is engaged through a separately prepared double-side hook hook-and-loop fastener.

FIG. 3 is a schematic cross-sectional view showing an example of the structure of the double-side hook hook-and-loop fastener used in the present invention.
The double-side hook hook-and-loop fastener used in the present invention does not need to have an engagement element on the entire surface, and if it is in the form of a tape, it may be preferable to have no engagement element in the center. Furthermore, if the double-side hook hook fasteners on both ends are combined with stretchable fabrics or sheets, it will be easier to follow when the distance between the ends of the torso is enlarged or reduced according to the movement of the human body. It is preferable because an improved wearing feeling can be obtained.

FIG. 4 is a developed plan view showing another example of the diaper cover according to the present invention. FIG. 5 is a schematic plan view showing a shape when the diaper cover shown in FIG. 4 is used.
The overall structure of the diaper cover of FIG. 4 is almost the same as that of FIG. 1, and the arrangement location of the hook-and-loop fastener is different. Loop surface fasteners 6 and 6 ′ are attached to both end portions on the surface side of the body portion 1, and a loop surface fastener 7 is attached to the inside of the end portion of the body portion 1. Further, loop surface fasteners 8, 8 ′ are attached to both sides inside the body portion 2.

As shown in FIG. 5, both end portions of the body portion 1 are bent inward so that the hook-and-loop fasteners 6 and 7 at the end portions are stacked. Both end portions are locked between the loop surface fasteners 6 and 7 to be stacked through a double-side hook surface fastener (not shown). Next, the crotch portion 2 is stacked on the body bent portion, and the loop surface fastener 6 on the surface of both ends of the body portion and the loop surface fastener 8 on both ends of the crotch portion are stacked, and they are hooked on both sides. It engages via a hook-and-loop fastener (not shown), and the shape of the trunk | drum 1 and the crotch part 2 is fixed.
The diaper cover shown in FIG. 5 has many advantages in that it is possible to more firmly fix the torso, although there are many laying of hook-and-loop fasteners and the number of operations is increased.

When washing after using the diaper cover described above, the hook-and-loop hook fastener 5 is removed and stored or discarded after the hook-and-loop fastener engagement between the crotch portion 2 and the trunk portion 1 is peeled in the reverse procedure. As a result, only loop hook-and-loop fasteners are attached to the diaper cover, so that it does not engage and damage other textile products during washing, and many diaper covers can be washed at the same time, or other textile products. There is no problem with washing together.
The diaper cover after washing and drying does not get entangled with fiber waste unlike conventional products, so there is no need to remove them and it is more hygienic if a new double-side hook hook-and-loop fastener is used.

  The fiber product with a hook-and-loop fastener of the present invention can be applied not only to the above-described diaper cover but also to linen products, underwear, general clothing, sports clothing, uniforms, work clothes, and the like.
