Detailed Description

For further understanding and appreciation of the invention, reference will now be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings.

Referring to fig. 1, the present invention is a water transfer film with environmental protection and without using an activator, comprising:

a high water absorption film 1 with strong water absorption; in a specific embodiment, the super absorbent film 1 is mainly made of Polyvinyl alcohol (PVA); in order to enhance the crosslinking effect of the super absorbent polymer film 1, in a preferred embodiment, the super absorbent polymer film 1 further comprises a polyvinyl alcohol emulsion resin and a surfactant;

a hydrophilic material layer 2, which is formed by hydrophilic materials in a layer shape, and the hydrophilic material layer 2 absorbs water from one end surface of the high water absorption film 1 and is softened, and then is cross-linked to the hydrophilic material layer 2 from the other end surface; in a preferred embodiment, the hydrophilic material layer 2 mainly comprises Polyvinylpyrrolidone (PVP); and

a message body 3 disposed on the hydrophilic material layer 2; in the embodiment, the message body 3 is ink and is dispersed in the hydrophilic material layer 2, so in a specific embodiment, the message body 3 is hydrophilic color master, so that the message body 3 and the hydrophilic material can be directly distributed on the surface of the super absorbent film 1 after being mixed to form a message with patterns, characters or a combination thereof; the hydrophilic material disposed on the super absorbent film 1 of this embodiment can be sprayed or directly coated by mechanical or manual methods, but is not limited thereto.

Accordingly, as shown in fig. 2, the flow of water transfer printing in this embodiment can be as follows:

s001: the high water absorption film 1 is laid on a water surface.

S002: the hydrophilic material layer 2 is formed by disposing the hydrophilic material containing the information body 3 on the upper surface of the super absorbent polymer film 1.

It should be noted that the sequence of steps S001 and S002 is not fixed and not changeable, and in one embodiment, the super absorbent film 1 may be laid on the water surface after the hydrophilic material layer 2 is formed on the super absorbent film 1.

S003: therefore, when the super absorbent polymer film 1 is laid on the water surface, the super absorbent polymer film is placed still, the standing time can be determined according to the time that the super absorbent polymer film 1 and the hydrophilic material layer 2 can be crosslinked, and can be about 10 to 60 seconds, so that the end surface of the super absorbent polymer film 1 contacting with the water surface absorbs water and is softened, and the other end surface is crosslinked on the hydrophilic material layer 2, so that the hydrophilic material is also softened synchronously, and the adhesiveness is generated.

S004: as in the conventional water transfer method, a transfer object is pressed into water toward the hydrophilic material layer 2, so that the hydrophilic material layer 2 and the super absorbent film 1 can be transferred to the transfer object according to the contour of the transfer object.

Then, as in the conventional water transfer printing technique, the transfer object is washed by water to dissolve and wash away the softened super absorbent polymer film 1, and the process such as baking can be performed, so that the information body 3 can be surely transferred and adhered to the transfer object.

According to the type, characteristics and requirements of the information body 3, the information layer does not need to be dispersed in the hydrophilic material layer 2, so in another embodiment, as shown in fig. 3, the information body 3 is layered to cover one end of the hydrophilic material layer 2 opposite to the super absorbent film 1, specifically for example, the information body 3 can be a water transferable laser coating with a metal material, which belongs to the prior art and is not described herein again.

Thus, as shown in fig. 4, the transfer method of the present embodiment generally includes the following steps:

s005: the high water absorption film 1 is laid on a water surface.

S006: a hydrophilic material is arranged on the upper surface of the high water absorption film 1 to form the hydrophilic material layer 2, and an information body 3 is arranged at one end of the hydrophilic material layer 2 opposite to the hydrophilic material layer 2, so that the information body 3 is covered on the top end of the hydrophilic material layer in a layered manner.

It should be noted that the hydrophilic material layer 2 of the present embodiment may be only a hydrophilic material, or may be a hydrophilic material layer 2 formed by a hydrophilic material including the information bodies 3 as described in the previous embodiments, so as to improve the layering, diversity and aesthetic property of the water-transferred graphics.

As mentioned above, the sequence of steps S005 and S006 is not fixed and can not be changed, and in one embodiment, the hydrophilic material layer 2 and the layered information body 3 can be formed in sequence before the super absorbent film 1, and then the super absorbent film 1 can be laid on the water surface.

S007: standing to ensure that the end face of the high water absorption film 1 contacting the water surface absorbs water and softens, and is crosslinked to the hydrophilic material layer 2 at the other end face; the standing time is determined by the time for the super absorbent film 1 and the hydrophilic material layer 2 to cross-link, which may be about 10 to 60 seconds, so that the super absorbent film 1 absorbs water and softens at the end surface contacting the water surface, and cross-links to the hydrophilic material layer 2 at the other end surface, so that the hydrophilic material is also softened simultaneously, and the layered information body 3 is provided with tackiness.

S008: as in the conventional water transfer method, the transfer object is pressed into water toward the hydrophilic material layer 2, so that the hydrophilic material layer 2 and the super absorbent film 1 are transferred onto the transfer object.

Then, as in the conventional water transfer printing technique, the transfer object can be washed by water to dissolve and wash away the softened super absorbent polymer film 1, and the process such as baking can be performed, so that the information body 3 can be surely transferred and adhered to the transfer object.

Therefore, the invention can generate cross linking with the hydrophilic material layer 2 after absorbing water through the high water absorption film 1 without using an activating agent, and can synchronously soften, so that the message body 3 can be transferred to the transfer object, thereby improving the transfer efficiency of the water transfer technology, avoiding the environmental ecological pollution caused by using the activating agent, achieving the effect of environmental protection, and avoiding the harm of the health of workers; in addition, because the whole high water absorption film 1 is laid on the water surface, the whole film can be cross-linked with the hydrophilic material layer 2, so that the message of the pattern, the character or the combination of the message body 3 is not easy to be deformed, and the precision, the aesthetic property and the production yield of the water transfer printing can be improved.

However, the above description is only a few preferred embodiments of the present invention, and it should be understood that the scope of the present invention should not be limited thereby, and that all equivalent changes and modifications made in the claims and the content of the present specification should be covered by the present invention.
