Problems solved by technology

However, the ink thermal transfer pattern feels hard, has no three-dimensional effect, poor resilience, and ink printing pollution is relatively large, which will cause great harm to the body of workers
Among the current printing materials, silicone printing has the advantages of good hand feeling, high temperature resistance, low temperature resistance, and not easy to age, and has become a representative of the new generation of printing materials. However, because silica gel itself is thermosetting, it is difficult to transfer.

Embodiment 1

[0018] Embodiment 1: A thermal transfer printing system of the present invention, which includes a release film, a hot melt glue, a thermal transfer printing silica gel and a positioning film arranged in sequence from bottom to top.

[0019] The release film is glass fiber cloth.

[0020] The hot-melt glue is formed by melting 30% of TPU colloidal particles and 70% of cyclohexanone in parts by mass.

[0021] The thermal transfer silicone rubber is an addition type liquid silicone rubber, and the addition type liquid silicone rubber contains 0.05% by weight of an aluminate coupling agent.

[0022] The positioning film is a polyurethane film.

[0023] A positive transfer printing process, comprising the following steps: sticking a glass fiber cloth release film on a screen printing table top, screen printing hot melt glue on the release film, cooling to room temperature to form a hot melt adhesive transfer layer, Print thermal transfer silicone on the hot melt adhesive transfe...

Embodiment 2

[0028] Embodiment 2, this embodiment is substantially the same as Embodiment 1, the difference is that the glass fiber cloth release film is pasted on the screen printing table top, and then TPU rubber particles with a mass fraction of 40% are printed on it Hot-melt glue composed of 60% cyclohexanone, printing thickness 0.2mm, cooled to room temperature after drying at 120 degrees, printing addition-type liquid silicone rubber on it, the addition-type liquid silicone rubber contains 0.1% by weight Aluminate coupling agent, baked in an oven at 110°C for 1 hour, and then laminated a polyurethane positioning film on it to obtain a positive transfer silicone product. Remove the release film from the product, press it on the knitted fabric at 150°C on a press machine for 15 seconds, and tear off the positioning film to obtain positive transfer silicone printing.

Embodiment 3

[0029] Embodiment 3, this embodiment is substantially the same as Embodiment 1, the difference is that the glass fiber cloth release film is pasted on the screen printing table top, and then TPU rubber particles with a mass fraction of 40% are printed on it Hot-melt glue composed of 60% cyclohexanone, printing thickness 0.2mm, after drying at 120 degrees, cool to room temperature, and print addition-type liquid silicone rubber on it, the addition-type liquid silicone rubber contains 0.05% by weight Aluminate coupling agent, then baked in an oven at 120°C for 30 minutes, and then laminated a polyurethane positioning film on it to obtain a positive transfer silicone product. Tear off the release film from the product, press it on the knitted fabric at 150°C on a pressing machine for 15 seconds, and tear off the positioning film to obtain positive transfer silicone printing.

Abstract

The invention discloses a thermal transfer printing system. The thermal transfer printing system comprises a release film, hot-molten glue, thermal transfer printing silica gel and a positioning film which are sequentially arranged from bottom to top. The invention further discloses a positive transfer printing process which comprises the following steps: silk-screen printing hot-molten glue on the release film, reducing a table temperature to the room temperature, and printing thermal transfer printing silica gel on a hot-molten glue surface according to a needed thickness, transferring the hot-molten glue surface to a drying oven to dry, and fitting a thermal transfer printing silica gel surface to the positioning film. The silica gel thermal transfer printing system has the advantages of being ultra soft in sample, easy to operate, good in bonding, resistant to pulling, resistant to washing and high in qualification rate. A thermal transfer printing sample obtained through the positive transfer printing process can adopt a pressing transfer-printing process, and keeps the surface effects such as super softness, easy operation, good bonding, pulling resistance, washing resistance and high qualification rate of directly printed silica gel.

Description

technical field [0001] The invention relates to the field of screen printing, in particular to a thermal transfer printing system and a positive transfer printing process. Background technique [0002] Silicone is a kind of high molecular polymer that is friendly to the environment and has the properties of both inorganic materials and organic materials. Because of its physiological inertness, adhesion and curing on the surface of fibers, it can modify, repair, beautify the appearance of fibers, and improve its functions. It is an excellent textile finishing agent. With the development of science and technology and the growing demand of people, the research on silicone in coating and screen printing emerges in an endless stream, and the part of the market that gradually replaces ink paste has also received more and more attention. [0003] Thermal transfer printing technology has been used in the fabric thermal transfer printing industry for a long time. With the rapid deve...
