Description

The invention relates to a rainproof clothing a zipper construction that a two-part has zipper with teeth facing each other arranged opposite each other on a support are the ver with the associated garment is sewing, with at least one of the two leads manure parts with a zipper to the front outstanding stripes is provided as a transition.

The invention also relates to a production method for waterproof or rainproof clothing.

Problematic and a weak point in rainproof  Clothing is the place where zippers are are arranged. To prevent water or water from entering It is to prevent moisture in this area known with the clothing parts in this area To transgress and to undertravel, respectively protrude the zipper parts forward, and the overlap accordingly. In this way a direct penetration of water is prevented changes, but the problem continues to be the carrier, which is generally made of a textile material stands, and the seams. All known attempts, the Solving the problem in terms of clothing technology did not lead to the desired success. About the textile structure the moisture is submerged by the capillary effect the crossover transports and can over the seam thread in through the puncture hole or infiltrate an overlap on the side. This leads to the penetration of moisture can spread inside. You got stuck represents that the propagation speed 1 cm per Minute, which means that it is within a short time zem to moisturize the underlying be clothes can come. The sense of a rain or what This means that waterproof clothing is no longer ge give.

The present invention is based on the object a waterproof or rainproof clothing at the beginning to create the kind mentioned in which an intrusion of Water or moisture in the area of a zip final construction is better prevented.

According to the invention, this object is achieved in that the carrier to the rear - based on the teeth of the Zipper - is extended, and that between the extended part of the carrier and the outside clothing over it a water dense coating is applied.

By extending the carrier and attaching it a waterproof coating in this area becomes a moisture wicking which then results over the seams due to the sewing of the zipper would take place on the garment, ver avoided. In addition to a direct entry of moisture and wetness also becomes an indirect penetration about the suction effect of the clothing stone on top les avoided.

Another advantage of the solution according to the invention is that this water resistance is simple re and thus more cost-effective way is achieved.  

By the zipper construction according to the invention can on the training of a previously common over occurs in a separate operation poses and must be sewn on, to be dispensed with.

This eliminates the otherwise usual additional seam seal, resulting in an overall more cost effective Manufacturing leads. By the water according to the invention dense coating can also be used if necessary the customization of the tailoring technology fall.

In a very advantageous and not obvious Further development of the invention can be provided that the coating layer with a thermoplastic adhesive cover line is provided.

Instead of a previous application of the thermopla tical adhesive top coat on the carrier, the water in a simple way even when sewing on the zipper conclusion of the clothing part at the same time be applied. It is only necessary for this Lich, for a corresponding heating device or ul trasound device and optionally a feed device for the thermoplastic adhesive to sor gen. This procedure has the further considerable Advantage that the seams at the same time  the sewing are glued or sealed so that penetration of moisture and moisture through the Be fastening seam for the zipper is prevented. It is also conceivable that sewing at all is dispensed with and the attachment of the fiction moderate zip through the thermoplastic Glue is done alone.

It is an advantage if between the adhesive top coat and a base coat is applied to the support. The This base line does not have to be made of a thermoplastic Glue exist because its essential task be is mainly just about the structure of the to compensate for underlying carrier material or to ensure a smooth surface.

In such a case it is not him either required that the adhesive layer cover the entire Surface of the carrier is applied. If necessary it may be sufficient if only a partial increase is carried out, which is of course a requirement is that in this case the bottom line is also off is made of a waterproof material. With a par The existing layer can be applied use the technology of a seam sealing machine  be generally used for processing from tape material in a width of 19 to 22 mm is laid.

For the baseline, a material can be made on polyurethane base.

For the adhesive top coat z. B. a material on bottom lyurethane or polyvinyl chloride base who used the.

The coating itself can have one or more layers be built.

In a further, not obvious embodiment the invention can be provided that inside or under the protruding strip of the Garment part (transition) a waterproof ges adhesive tape is arranged.

Through the waterproof tape under the strip there is also penetration of moisture in this area action or wetness due to "infiltration" different.

In a simple manner, the adhesive tape can also be used  a thermoplastic adhesive on the strip be increased.

The garment can be known as a Dreila gene or two-layer laminate. With Ver Using a two-layer laminate is an advantage the lining fabric sewn on the inside sew on in the area of the extension of the strap.

The following are exemplary embodiments based on the drawing games of the invention and a manufacturing process described in principle. It shows:

Fig. 1 detail of a garment with egg nem three-layer laminate and the inventive zipper construction as a front closure;

Figure 2 shows a detail of a zipper construction without a trained bottom;

Fig. 3 is a partial clothing part as a two-ply laminate with the inventive slide fastener structure;

Fig. 4 is a schematic representation of a sewing machine with the additional parts according to the invention for bringing up or activating a thermoplastic adhesive top coat.

Basically, the clothing part can be of any construction, provided that the condition of water or rain tightness is given, one should also advantageously provide a water vapor permeability for breathability. The Beklei dung part 1 1 shown in Fig. And 2, as Dreilagenlami nat constructed with an outer fabric layer 1 A, a middle layer which is formed as a membrane 1 B, and represents the waterproof functional layer and an inner fabric layer 1 C, with the Membrane 1 B is glued and protects it against damage. The inner textile layer 1 C can be formed as a knitted fabric or knitted fabric (see enlarged detail in a circle).

The zipper construction 2 consists in the usual way of two zipper parts 2 A and 2 B, each of which is provided with teeth 3 , which cooperate when closing and comb-like interlocking fen.

A clothing part 1 (the left in the drawing) is provided in the usual way with a protruding strip as a transition 4 , on the front edge of which a lockstitch seam 5 is introduced. The zipper 2 A is quilted about 5 to 6 cm before the end edge of the transition 4 with a lockstitch seam 13 on the inside of the clothing part 1 .

The execution of a bottom 6 for the other loading clothing part with the zipper 2 B, which cooperates with the transition 4 , takes place in the same Wei se. The zipper 2 B is placed on the inside of the bottom 6 as far from the front end edge that the clothing part with the functional layer of the base material is forcibly folded outwards when the zipper is closed and forms a rain gutter. This method is well known from the confection technology.

The textile carrier 7 of the two zipper parts 2 A and 2 B is extended to the rear by about 15 to 20 mm. A base coat 8 based on polyurethane is applied to the extended part (and possibly also to the front beyond it), through which a smooth surface is created. On the base line 8 , a thermoplastic adhesive layer 9 is applied as an adhesive layer. In addition, a waterproof adhesive tape 10 can also be applied to the underside of the transition 4 by a thermoplastic adhesive. Pushbuttons 11 on the underside of the transition 4 , which work in the usual way with Druckknopfge counterparts 12 on the top of the undercut, serve in the usual manner after closing the zipper construction 2 for a good overlap of the transition 4 and under occurs 6 .

As can be seen, the two zipper parts 2 A and 2 B with lockstitch seams 13 with the clothing parts 1 connected, the lockstitch seams 13 in the extended part 7 A of the textile support 7 are introduced. Due to the sealing by the thermoplastic adhesive top coat 9 and in particular also with the additional use of the adhesive tape 10 can optionally be formed on a bottom 6 , which he stretches over the zipper 2 B to the front, can be dispensed with. This configuration is shown in FIG. 2. As can be seen in the sem case the clothing part 1 in the region of the lengthened part 7 A of the textile carrier 7 and is hemmed there accordingly and connected to the zipper 2 B by the lockstitch seam 13 .

The embodiment shown in FIG. 3 egg ner clothing construction is basically of the same structure, only a two-layer laminate is used instead of a three-layer laminate for the clothing part 1 . The two-layer laminate also has an outer fabric layer 1 A and an inner membrane 1 B as a waterproof functional layer. In addition to the connection of the zipper 2 A or 2 B over the extended part 7 A of the textile carrier 7 with the base coat 8 and the thermoplastic adhesive deck 9 stroked over the lockstitch seam 13 with the clothing part 1 , a lining material 14 is also on the inside quilted in the same place and with the same lockstitch seam 13 .

In this garment construction, the inside of the transition 4 is thus without an absorbent layer. If protection of the inner membrane 1 B or the thermoplastic coating is required, this can be achieved with known technologies, such as. B. by means of heat setting or incorporation egg nes loose lining material, which is sewn into the front seam and the bottom 6 . Likewise, the adhesive tape 10 shown in FIG. 1 in the form of a thermoplastic adhesive strip can optionally also be applied to the underside of the transition 4 .

From Fig. 4 is in principle shows how the zipper construction is sewn onto the garment 1 2. For this purpose, a conventional sewing machine 15 can be used, which is additionally provided with a heating cartridge 16 as a heating device. The heating cartridge 16 has hot air outlet nozzles 17 for activating a thermoplastic coating material or adhesive top coat, which has been previously applied to the carrier of the zipper construction.

If the thermoplastic adhesive is brought up immediately before the sewing process or as a replacement for the sewing process, the sewing machine is provided with a corresponding feed device 18 . When applied by sewing, the clothing part 1 is inserted laterally under the needle 19 of the sewing machine 15 in the usual manner. As can be seen, the feed opening 20 of the feed device 18 is also in the region of the needle or shortly before. The zipper 2 A and 2 B is defined such positio under the needle 19 so that a quilted stitch seam can be introduced into the extended part of the textile support. 13

Due to the heating of the thermoplastic coating composition that emerges from the opening 20 , the coating composition can be applied at the desired location, ie on the extended part of the textile backing. Then after inserting the lockstitch 13, the clothing part by pressing 21 roll pressed accordingly, so it follows a compression and thus a firm adherence of the thermoplastic adhesive top coat on the clothing part 1 and the textile backing 7 , which at the same time also resulted from sewing Punctures in the waterproof functional layer 1 B who sealed the.

The activation of the thermoplastic adhesive can also by other methods, such as. B. from the Hot wedge or ultrasound technology are known, successfully Corresponding mechanical equipment are known for this.
