Description

Velcro pad and its manufacturing method {VELCRO PAD AND MANUFACTURING METHOD THEREOF}

The present invention relates to a velcro and a method of manufacturing the same, and more particularly to a velcro used as an accessory for clothing.

Velcro is a subsidiary material in which the hook surface and the roof surface are used as a set. The hook surface has a hook-shaped hook formed on one side of the Velcro fabric, and the loop surface is brushed so that the hook is coupled. Or multiple, elliptical loops.

The velcro is used to secure the hook-side and loop surface to each other so that the hook-shaped hook is fastened to the loop so that the members on both sides are not separated from each other by the fastening force between the hook and the loop.

On the other hand, recently, the development of a technology for printing a logo, a picture, a picture on the hook surface and the loop surface of the Velcro so that consumers can visually identify it from the front or side of the Velcro.

However, according to the prior art, there are some problems as follows when printing the hook surface and the loop surface of the translucent Velcro.

First of all, the Velcro hook surface and the loop surface should be fixed upside down for the multi-color printing work, the hook surface and the loop surface of the Velcro is protruded or raised, it is difficult to accurately fix.

In addition, even if fixed correctly, there is a problem that the print quality is deteriorated because the loop and the hook of the front part do not maintain the plane due to the pressure applied during the back printing.

On the other hand, when using a conventional organic solvent type of ink in the multi-color printing operation on the back of the Velcro, there is a problem of detecting the toxicity and the Velcro shrinkage or deformation during natural drying or heat drying after printing.

In particular, when shrinkage or deformation occurs in the printing surface, there is a problem that the defective rate is greatly increased in the cutting process according to a predetermined size and shape.

On the other hand, when the thermal transfer operation on the back of the Velcro, the characteristics of the loop (napping surface) is lost by the heat applied by the heat press has a disadvantage that the original detachable function of the Velcro is greatly weakened.

In addition, due to the inherent durability of the printing ink, there is a problem in that the printed matter is dropped off when using the Velcro or when washing.

Accordingly, there is an urgent need for a new methodology for solving the above problems in printing or displaying a predetermined logo, picture, etc. on the back of the Velcro.

In the meantime, in order to clarify the present invention, contents not related to the configuration of the present invention will be omitted, and the same reference numerals in the drawings are used to refer to the same components.

On the other hand, when any one component "contains" another component in the specific details or utility model registration claims for carrying out the invention, it is limited to consisting of only the component unless otherwise stated, interpretation It is to be understood that the present invention is not limited to that, and may further include other components.

As shown in Figure 2, first, the Velcro pad according to the present invention can be manufactured through the following process.

First, a PET (polyethylene terephthalate) film for thermal compression is prepared, and an adhesive crosslinking agent is applied to the back side by a silk printing method. Then, it is dried at room temperature (S110).

At this time, preferably, the adhesive crosslinking agent may be a mixture of polyamide powder in a predetermined ratio in a liquid adhesive.

Thereafter, the adhesive crosslinking agent is sufficiently dried and then prints a predetermined logo or picture on the adhesive crosslinking agent coated surface (S120). In this case, a silk screen method may be used as the printing method, but is not limited thereto.

When the print 2 is sufficiently dried, a polyamide-based adhesive is applied to the printed surface and then dried at room temperature (S130).

This serves to prevent deformation of the print 2 when heat and pressure are applied to the print 2.

Thereafter, the adhesive crosslinking agent is applied to the dried adhesive coating layer by a silk printing method, and then dried again at room temperature (S140). At this time, the adhesive crosslinking agent used may also be a mixture of polyamide powder in a predetermined ratio in the liquid pressure-sensitive adhesive.

On the other hand, the translucent Velcro 1 is prepared separately from the Piti film.

The adhesive crosslinker is applied to the back surface of the prepared surface of the translucent Velcro 1 by the hook 10 or the loop 20 by a silk printing method and then dried at room temperature (S150).

At this time, preferably, the adhesive crosslinking agent may be a mixture of polyamide powder in a predetermined ratio in a liquid adhesive.

Thereafter, the PTI is thermally compressed while being laminated on the back of the Velcro. Thereby, the polyamide powder mixed in the adhesive crosslinking agent is melted, and the printed matter 2 is adhered to the back surface of the velcro 1. Thereafter, the PTI is removed (S160).

Meanwhile, the Velcro 1 is laminated on the upper end of the detachable pad 3 prepared in advance separately, and then the detachable pad 3 is attached to the Velcro 1 by thermal compression (S170).

Looking at the process in detail, first, the Velcro 1 is laminated on the upper side of the detachable pad 3 and then placed on a thermocompression press, and the final result is obtained by compressing for a predetermined time at a constant temperature and pressure.

At this time, the detachable pad 3 is treated so that one side may be easily attached or detached from any material surface, and may be a foam having a predetermined thickness and elasticity.

Through the above process, as shown in FIG. 1, a Velcro 1 having a structure in which the printed matter 2 and the detachable pad 3 are sequentially stacked on the bottom may be manufactured.

On the other hand, the printed matter 2 may be preferably printed using a two-component curable ink prepared by blending epoxy and hardener in a predetermined ratio in a colored ink paint to secure sufficient durability of the printed matter.

The Utility Model Registration Application No. 20-2011-9523 filed by the applicant of the present application has disclosed a method of preparing ink for securing the durability of the printed matter, and in the present invention, the Utility Model Registration Application No. 20-2011-9523 It can print using the two-component curable ink known by the arc.

According to the prior art, when Velcro is used as an accessory for clothing, there is a problem in that the printed material is easily dropped due to frequent bending due to use and friction applied during washing. In particular, in the case of sublimation transfer, it is somewhat weak in washing or bending. Even when the transparent film is attached to the printed matter by high frequency bonding, the transparent film is also not easily bonded by the printed matter and tends to fall off easily due to warpage.

The two-component curable ink can be prepared by blending epoxy and hardener in a predetermined ratio in a colored ink to solve this problem.

In this case, the colored ink paint used may be a paint generally used in the field of garment printing technology.

However, the curing agent is preferably imidazole, polyamine, diethyl amino propylamine, phthalic acid anhydride, aliphatic amine, aromatic amine in view of the specificity of the printing process. (Aromatic amine), phthalic anhydride, polyamide resin, polysulfide resin, phenol (phenol), disadian diamide (or more) is used.

Experimental results showed that diethylene triamine cured at room temperature was suitable.

As for the ratio of an epoxy and a hardening | curing agent, about 6: 4-7: 3 are suitable. That is, 60-70 weight% of epoxy resins and 30-40 weight% of hardening | curing agents are mix | blended.

Thereafter, the mixture is mixed with a colored ink paint prepared in advance, and then stirred so that bubbles are not mixed.

At this time, when the viscosity is too high, a small amount of epoxy thinner can be added.

On the other hand, the Velcro pad according to the present invention may be manufactured by a method of directly printing on the back of the Velcro, unlike the embodiment described above.

As shown in Figure 3, first apply a primer to the back of the translucent Velcro (1) and then dried at room temperature (S210).

On the other hand, when the primer is sufficiently dried, a predetermined logo or picture is printed on the back of the translucent Velcro (1) (S220).

In this case, in order to ensure durability of the printed matter 2, the two-component curable ink as described above may be used.

On the other hand, as the printed material 2 is dried, the polyamide powder is mixed and applied to the liquid adhesive on a printing surface of the rear surface of the translucent Velcro 1 in a predetermined ratio (S230).

Thereafter, the upper side of the detachable pad 3 and the back surface of the velcro 1 are laminated to face each other, and then placed on a thermocompression press, and the upper and lower portions of the detachable pad 3 are compressed at a predetermined temperature and pressure for a predetermined time. (1) to be attached to the back (S240).
