[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.

[0037] The directional terms mentioned in the present invention, such as "up", "down", "front", "back", "left", "right", "inside", "outside", "side", "top" and "bottom", are only for reference to the orientation of the drawings. The directional terms used are used to illustrate and understand the present invention, but not to limit the present invention.

[0038] The terms "first", "second", etc. in the present invention are used for descriptive purposes only and should not be understood as indicating or implying relative importance, and should not be used as a limitation on the order of precedence.

[0039] Most zippers in the prior art have an anti-fouling layer on the interlocking chain teeth to prevent moisture, dust and dirt from entering through the zipper, but the effect is not good. As the length of use increases or the zipper is pulled, the expansion and contraction deformation will cause the anti-fouling effect to decrease significantly.

[0040] The following is a preferred embodiment of a nylon anti-fouling and easy-to-clean zipper provided by the present invention that can solve the above technical problems.

[0041] Please refer to Figure 1 and Figure 3 ,in Figure 1 Schematic diagram of the structure of a preferred embodiment of the nylon antifouling and easy-to-clean zipper of the present invention. Figure 3 for Figure 2 The cross-sectional structure in FIG. 1 is a structural diagram when the cross-sectional structure is not covered with a reinforcing membrane layer.

[0042] In the figures, structurally similar elements are denoted by the same reference numerals.

[0043] The present invention provides a nylon anti-fouling and easy-to-clean zipper, which comprises a slider 13, a chain tooth row 11, a core wire 19, a zipper tape 17 and an anti-fouling film layer 18.

[0044] The two mutually engaged fastener rows 11 are sewn one by one along the side edges of the two zipper tapes 17 and connected, and the core wire 19 passes through the fastener row 11 along the length direction of the fastener row 11. Figure 2 The fastener element row 11 connected with the core thread 19 is sewn and fixed on the zipper tape 17 by the sewing thread 111, and the anti-fouling film layer 18 is arranged on one surface of the zipper tape 17.

[0045] The chain tooth row 11, zipper tape 17 and anti-fouling film layer 18 are all connected in the locking groove of the slider 13. The slider 13 is used to engage or disengage the two chain tooth rows 11. When the two chain tooth rows 11 are engaged with each other, the two anti-fouling film layers 18 are in contact with each other to form a seal. Anti-fouling agent is applied to the anti-fouling film layer 18, the chain tooth row 11 and the core wire 19. The anti-fouling agent can form a hydrophilic and durable film on the surface of the fabric, which can play an anti-fouling role and can be easily cleaned even if there is dirt.

[0046] In the present invention, the zipper tape 17 and the fastener element row 11 are made of polyethylene terephthalate, the antifouling agent is an antifouling agent containing polysilazane, and the antifouling film layer 18 is made of TPU (thermoplastic polyurethane elastomer rubber).

[0047] Please refer to Figure 2 ,in Figure 2 For along Figure 1 The cross-sectional structure diagram made by the AA cutting line in.

[0048] like Figure 2 In the embodiment, one side of the chain tooth row 11 is the inner side. With the increase of the use time and the deformation of the zipper, a gap is easily formed between the two anti-fouling film layers 18, and dirt such as dust and moisture can easily enter into the space between the chain tooth row 11 and the anti-fouling film layer 18. Although the chain tooth row 11 with anti-fouling agent can play a barrier and anti-fouling effect, in order to further enhance the anti-fouling performance, the nylon anti-fouling and easy-to-clean zipper of the present invention can also be provided with a reinforcing film layer 12.

[0049] The reinforcement film layer 12 is disposed on the antifouling film layer 18 and is located outside the slider 13. Figure 1 The middle slider 13 is located between the anti-fouling film layer 18 and the reinforcing film layer 12. When the two tooth rows 11 are engaged with each other, the two reinforcing film layers 12 are laminated and sealed. Figure 1 The middle pull tab is outside the reinforcing film layer 12 , but in order to clearly show the reinforcing film layer 12 , the pull tab of the slider 12 is shown with a dotted line.

[0050] Of course, around the slider 12, since the reinforcing film layer 12 is squeezed and lifted up, there is an open gap, and the reinforcing film layer 12 has a poor sealing and anti-fouling effect on the surrounding area, but for example Figure 1The sealing and anti-fouling effect of the two areas at the lower part of the middle slider 12 that engage with the chain element rows 11 is better.

[0051] The reinforcing film layer 12 is made of elastic rubber material, and its flexibility is greater than that of the anti-fouling film layer 18 , so that when the slider 13 slides, the slider 13 can better squeeze the reinforcing film layers at different positions to deform them.

[0052] like Figure 3 In the figure, the reinforcing film layer 12 on the two zipper tapes 17 is provided with a deformation section of a set width near the slider 13. The thickness of the deformation section gradually becomes thinner from the end away from the slider 13 to the end close to the slider 13, so as to facilitate the laminated sealing of the reinforcing film layer 12. At the same time, the gradual change in thickness is also more conducive to the bending deformation of the slider 13 when it is squeezed.

[0053] For the sake of clarity, the reinforcement film layers 12 on the two zipper tapes 17 are respectively the first reinforcement film layer and the second reinforcement film layer. Figure 2 The membrane layer at the middle left end, the second reinforcement membrane layer is as follows Figure 2 The membrane layer at the middle right end, the first reinforcement membrane layer is laminated and sealed on top of the second reinforcement membrane layer, the bottom surface of the deformation section of the first reinforcement membrane layer gradually becomes thinner, and the top surface of the deformation section of the second reinforcement membrane layer gradually becomes thinner. The bottom surface of the deformation section of the first reinforcement membrane layer and the top surface of the deformation section of the second reinforcement membrane layer are both smooth surfaces, and the smooth surface makes the fitting effect better and the sealing stronger.

[0054] Please refer to Figure 2 The reinforcing film layer 12 is coated on the outside of the antifouling film layer 18 and the zipper tape 17. The reinforcing film layer 12 includes an upper layer covering the surface of the antifouling film layer 18 and a lower layer covering the surface of the zipper tape 17. The upper layer, the antifouling film layer 18, the zipper tape 17 and the lower layer are sewn and reinforced by a reinforcing line 121. The position of the reinforcing line 121 can be combined with reference to Figure 1 and Figure 2 .

[0055] Please refer to Figure 1 Along the length direction of the zipper tape 17, fixing parts 16 are provided at both ends of the reinforcing film layer. The fixing parts 16 include an upper clip and a lower clip. The upper clip and the lower clip are made of a harder plastic material. The upper clip is pressed on the surface of the upper layer, and the lower clip is pressed on the surface of the lower layer.

[0056] On the other hand, the rivets 161 may penetrate the upper clip, the upper layer, the antifouling film 18, the zipper tape 17, the lower layer and the lower clip to form a fixed structure.

[0057] In order to enhance the fit and sealing of the reinforcing film layer 12, a plurality of magnet segments 122 may be spaced apart along the length direction on the deformation section of the reinforcing film layer 12. The magnet segments 122 are magnet sheets with a thickness of less than 0.5 mm and may be integrated into the reinforcing film layer 12. At the same time, by spaced apart the magnet segments 122, the bending performance of the zipper is less affected. The two reinforcing film layers 12 form a magnetic seal through their respective magnet segments 122, and the sealing effect is good.

[0058] The zipper of the present invention also includes a front stopper 14 located at one end of the zipper tape 17 and a rear stopper 15 located at the other end. The rear stopper 15 includes an insert, a socket, and a seat tube connected to the socket. The reinforcing film layer 12 and the rear stopper 15 are staggered to form an avoidance position so that the slider 13 can be paired with the rear stopper. The reinforcing film layer 12 is pressed and fixed in the front stopper 14.

[0059] Please refer to Figure 4 ,in Figure 4 The present invention is a flow chart of a method for manufacturing a nylon antifouling and easy-to-clean zipper.

[0060] The present invention also includes a method for manufacturing the above-mentioned nylon anti-fouling and easy-to-clean zipper, which comprises the following steps:

[0061] Step S101: applying an antifouling agent to the core wire 19;

[0062] Step S102: inserting the core wire 19 in step S101 into a pair of mutually engaged fastener element rows 11;

[0063] Step S103: applying the antifouling agent to the pair of fastener element rows 11 in step S102, and performing the antifouling agent application operation before the core wire 19 is connected and after the core wire 19 is connected to the fastener element row 11, so that the application is more comprehensive;

[0064] Step S104: sewing the pair of fastener element rows 11 in step S103 onto the corresponding pair of zipper tapes 17;

[0065] Step S105: bonding or welding the anti-fouling film layer 18 on the pair of zipper tapes 17 in step S104. At this time, the anti-fouling film layer 18 is an integral anti-fouling film layer covering the two zipper tapes 17.

[0066] Step S106: applying an antifouling agent to the antifouling film layer 18 in step S105 to further improve the antifouling effect;

[0067] Step S107: heat-treating the zipper in step S106 so that the antifouling agent settles and the antifouling agent is more tightly bonded to the chain element row 11, the core wire 19 and the antifouling film layer 18;

[0068] Step S108: After the antifouling film layer 18 in step S107 is bonded and stabilized, it is cut and separated, and an antifouling agent is applied to the cut of the antifouling film layer 18. First, an integral antifouling film layer 18 is formed on a pair of zipper tapes 17 that are occluded and connected, and heat-treated, and then cut and separated. The thermal deformation is small, so that the two antifouling film layers 18 formed are neatly butted against each other, and the sealing effect is better.

[0069] Step S109: The outer surface of the antifouling film layer 18 and the zipper tape 17 in step S108 is covered with a reinforcing film layer 12, and the upper layer, the antifouling film layer 18, the zipper tape 17 and the lower layer are sewn and reinforced into a more stable overall structure through a reinforcement line 121;

[0070] Step S110: installing the front code 14 and the rear code 15;

[0071] Step S111: Install the fixing member 16 and use the rivet 161 to penetrate the upper clip, the upper layer, the anti-fouling film layer 18, the zipper tape 17, the lower layer and the lower clip to fix them.

[0072] Among them, the application of waterproofing agent can be carried out by immersion and spraying.

[0073] The nylon antifouling and easy-to-clean zipper of the preferred embodiment is antifouling by the combination of the antifouling film layer and the antifouling agent, and has a good antifouling effect. Even if it is deformed after long-term use, the antifouling effect can still be obtained through the antifouling agent.

[0074] In addition, by providing a reinforcing film layer, when two tooth rows are engaged with each other, the two reinforcing film layers are laminated and sealed. Even if the laminated sealing structure is deformed after long-term use, it is not easy to separate and can still maintain a good seal, further improving the anti-fouling effect.

[0075] In summary, although the present invention has been disclosed as above in terms of preferred embodiments, the above preferred embodiments are not intended to limit the present invention. A person skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be based on the scope defined in the claims.
