Definitions

the invention relates to a composite element for a hook-and-loop fastener, in particular for a diaper closure, comprising a backing and a textile material laminated to the backing, which comprises a base structure formed from threads or fibers and threads incorporated into the base structure by knitting into the base structure integrated threads for connection with Velcro hook provided loops and wherein at least a portion of the threads or fibers of the basic structure of polyamide is formed.
Velcro closures consist according to their usual design of a loop part and a hook part. Corresponding hook-and-loop fasteners are also referred to as hook-and-loop systems. Velcro fasteners are used for both multiple use and disposable items such as diapers, especially baby diapers or adult incontinence articles.
the textile material may be formed of polypropylene, polyester or polyamide.
the object of the present invention is to provide a composite element with a carrier and a textile material laminated to the carrier, which has an improved hook-and-loop action especially in bonded areas.
the composite element should furthermore be inexpensive and in particular also suitable for disposable articles.
the object is achieved according to the invention in that the threads integrated into the basic structure by knitting have polyolefin, in particular polypropylene, as the main constituent.
the present invention thus teaches to use different materials for at least some of the filaments or fibers of the basic structure on the one hand and the threads incorporated into the basic structure on the other hand, taking into account the respective different requirements for the basic structure and the loops intended for use with the Velcro hooks.
the basic structure must have a high strength and be laminated well with the carrier, which is preferably a film, by adhesive.
the carrier which is preferably a film, by adhesive.
Polyamide meets these requirements, because it not only has a high strength, but also due to its polarity very well with an adhesive, such as a laminating adhesive based on polyurethane, can be bonded.
the inventively provided in the basic structure fibers or threads of polyamide ensure a secure bond with the carrier and high strength.
the present invention further teaches, for the threads knitted into the basic structure which form the loops provided for connection with the hook and loop, to use another material which comprises polyolefin, in particular polypropylene, as the main constituent.
Main ingredient means the polyolefin content of the material is at least 50% by weight and preferably at least 80% by weight.
the corresponding thread may also consist entirely of polyolefin, in particular propylene.
Polyolefins, in particular polypropylene have no or only a comparatively low polarity and can therefore usually be glued poorly.
the basic structure of the textile material can be formed in different ways in the context of the invention.
a nonwoven formed from fibers which is then formed from polyamide fibers or a fiber mixture with a considerable proportion of polyamide fibers.
the basic structure is woven, knitted or knitted.
at least one thread type made of polyamide, which participates in the formation of the basic structure is provided.
a knitted basic structure may in principle be formed from a thread type, ie a plurality of threads, all of which are processed according to the same laying pattern.
a knitted basic structure two types of thread with a different leveling are provided. This makes it possible to adjust the strength and other properties of the knitted textile material.
the polyamide threads have polyamide as a main component. In the usual way, however, it is also possible to provide additives, fillers, processing aids, dyes, coatings or the like which, for example, have a weight fraction of less than 30%, preferably less than 15% of the total thread material.
wales form in the effective direction, ie in the direction of production of the knitted fabric, and courses of stitches in the transverse direction.
a laying pattern is provided for the first type of thread, according to which this type of thread at least two wales, in particular two adjacent wales, connects.
the threads of the second thread type are largely free in the context of such a configuration between the wales and therefore can be glued well.
the threads running between the wales may also be subject to great tensile forces when using the composite element, so that it is precisely these which must have high stability, which is why polyamide is also suitable as a tensile material, especially for this first type of thread.
the second type of thread on the other hand, can run exactly along a wale in the effective direction. Depending on the requirements and thread thickness of the described second thread type can then be formed from cost polyolefin, in particular polypropylene. However, if higher tensile strengths are necessary, the filaments of the second type of thread may be formed of polyamide.
monofilament threads and / or multifilament threads can in principle be used.
first thread type is provided as a monofilament thread and / or if the threads forming the loops are multifilament threads.
Multifilament threads are particularly suitable for connection with Velcro hooks, because a certain Velcro effect is already achieved if only a part of the filaments of Kletthaken is under attack. Especially with the free-running loops results in a multifilament thread also a much softer surface.
the composite element as a diaper closure only a limited number of opening and closing operations are provided. Thus, if a part of the filaments breaks when opened on a loop, there still remains some of the filaments of the multifilament thread, which can be used for a further connection.
the threads of the second type of thread may optionally be formed as multifilament threads or monofilament threads.
the carrier in addition to a conventional film in principle also a nonwoven material into consideration, the carrier is often printed with a decor, which is then visible through the laminated textile material.
the carrier is formed from a single- or multi-layered film, this preferably has at least on the surface which is laminated with the textile material, a polyolefin, in particular polyethylene, as a main component. Particularly preferred is a low-cost single or multilayer polyethylene film.
both a full-surface and a partial-area adhesion can take place, in which case in the bonded areas improved Velcro is achieved because the loops there are less bonded due to the polyolefin material used, in particular polypropylene.
the basic structure with at least a proportion of threads of polyamide ensures a high stability and bond strength, so that in principle a non-full-surface bonding is sufficient, as in the EP 1 579 779 B1 and the EP 1 690 976 B1 is described.
the measures described there can also be used without restriction in the context of the present invention, so that then the adhesive is applied in a pattern which is composed of adhesive surfaces and adhesive-free areas.
Adhesive pattern with continuous lines and arranged therebetween adhesive-free cells are formed. It is also conceivable to provide a substantially rectangular lattice pattern, in which case individual wales are not fastened or only attached to crossing adhesive strips in conjunction with a knitted textile material.
the proportion of the bonded area is typically between 10% and 40%, preferably between 14% and 28% of the total area in the case of non-full-area application of adhesive.
Suitable are conventional laminating adhesives, in particular adhesives based on polyurethane.
the textile material which should be as light as possible for reasons of cost but nevertheless must have sufficient stability and Velcro effect, preferably has a basis weight between 10 g / m 2 and 40 g / m 2 , preferably between 14 g / m 2 and 28 g / m 2 on.
the backing When a film is used as the backing, it can usually be made relatively thin because it is essentially intended to handle the composite element easily and, for example, in the waist region to be able to apply a diaper.
the thickness of the preferably made of polyolefin, in particular polyethylene film may for example be between 10 .mu.m and 40 .mu.m, in particular between 15 .mu.m and 25 .mu.m.
Fig. 1 shows a composite element for hook-and-loop fasteners, in particular for a diaper closure, with a carrier 1 and with a clad on the support 1 2 textile material, which has a filament (L1, L2) formed basic structure and incorporated into the basic structure by knitting threads L3.
the threads L3 incorporated into the basic structure by knitting form loops 3 provided for connection with hook-and-loop hooks.
the presentation of the Fig. 1 shows the threads L1, L2, which form the basic structure, and the loops forming thread L3 greatly simplified.
the threads L1, L2, L3 do not run exactly in the direction of knitting or transversely thereto in a knitted basic structure, but are meshed together according to a given laying pattern, whereby a mutual wrapping of the threads L1, L2, L3 results at the individual stitches.
Fig. 2 and 3 which show an exemplary laying pattern for a knitted textile material as well as the corresponding textile material itself.
At least one of the threads L1 of the basic structure of polyamide is formed as an essential component, while the loop forming thread L3 as a main component polyolefin, in particular polypropylene.
the threads L1, L2 of the basic structure are securely connected to the carrier 1, in particular the first thread L1 or thread type of polyamide because of his Polarity can be glued very well.
Fig. 1 exemplified an embodiment is shown in which the adhesive is not applied over the entire surface, in which case the basic structure and in particular the relatively stable thread L1 made of polyamide ensure high strength.
the forces acting on the non-bonded areas during use of the composite element can be transmitted via the sufficiently stable basic structure into the bonded areas.
Fig. 2 shows by way of example a laying pattern for the textile material 2 of the composite element.
the entire textile material 2 is formed from three types of threads, ie three threads guided differently over the needles of a knitting machine and uniformly recurring in the transverse direction.
the basic structure is made of a first type of thread L1 and a second type of thread L2, wherein in the working direction W, ie the production direction, wales s and in the transverse direction form rows of stitches r.
the first thread L1 that is, the first thread type, is knitted so as to join two adjacent wales s, with the thread L1 going from stitch row r to stitch row r is led.
the first thread type L1 which gives the textile material 2 the stability in the transverse direction, consists of polyamide, for example PA6.
the second thread L2 or the second thread type of the basic structure is guided in the exemplary embodiment exactly along in each case one wale s in the direction W of the fabric.
this second thread L2 may be formed from polyamide or a polyolefin, in particular polypropylene. While in an embodiment of polyamide results in improved strength and bond strength, an embodiment of polypropylene allows a reduction of the total cost.
the third thread L3 or thread type is integrated into the basic structure and forms free loops 3.
the loops are produced by forming a free loop head between two loop loops entwined on one wale s, which does not interfere with the other threads L1 in the knitting process , L2 is meshed. After the kneading process, the loop 3 formed in this way can rise up and connect with Velcro hooks. Since the material of the loops 3 forming thread L3 is less strongly fixed in conventional laminating adhesives, the Velcro effect is improved in bonded areas.
