Why sublimation transfer printed T-shirt turning yellow,how to deal with it?

If we simply say thermal transfer paper, or sublimation transfer printed T-shirt , I believe that there are many people who don’t know. But you can look at the various patterns on your t-shirt, is it a simple understanding of the thermal transfer paper. Let's talk about why the thermal transfer paper will change color.

With the arrival of summer, many thermal transfer practitioners have started using sublimation printer to produce t-shirts. For some experienced friends,the production of thermal transfer t-shirts is relatively simple. However, for some novice friends,thermal transfer t-shirts are still prone to various minor problems. Below, the relevant personnel of the thermal transfer paper company will introduce the common problems of thermal transfer t-shirts. Solution.

Question 1: Thermal transfer t-shirt turning yellow

The case of thermal transfer t-shirt yellowing is more common, and the reasons for this phenomenon are often the following.

 Sublimation Transfer Printed T-shirt

1. The heating time is too long. It is well known that cotton t-shirts will appear yellow after a long period of high temperature. This is mainly due to the material of the t-shirt and is not unique to thermal transfer technology. Therefore, everyone must pay attention to the time in the production of thermal transfer t-shirts. Usually 20-25s is enough, don't increase the heating time privately because you are afraid of the transfer is not complete.

2, t-shirts contain cotton. A lot of friends don't know much about cotton materials. In fact, the t-shirts we usually see are usually low in cotton, usually 80. The less the cotton content, the less likely it is to yellow during the transfer process, but if it reaches 130 or more, everyone should pay special attention, and the t-shirt will often appear yellow. Therefore, when you choose a t-shirt, you must choose the right one. Do not blindly pursue the cotton content.

Question 2: T-shirts fall off after transfer

Image peeling after t-shirt transfer is also common, and most of this problem is caused by the quality of the thermal transfer t-shirt. Thermal transfer t-shirt paper must choose some more reliable companies, do not covet cheap, with some small manufacturers or t-shirts of companies that are just beginning to do thermal transfer, often caused by quality, but caused by Shedding situation.

Another situation is caused by insufficient pressure on the heat press machine. In fact, this is also a quality problem, so as with the above, there is not much explanation.

Question 3: Maintenance of thermal transfer t-shirt

Sublimation Printer

The thermal transfer t-shirt is actually no different from the ordinary t-shirt. The only thing that needs everyone's attention is not to expose it to ultraviolet light for a long time (the ink is easy to decompose). When not wearing it, put it in a dry environment. Avoid image shedding caused by moisture.

In fact, it is essentially a problem we often encounter in the use of dye sublimation paper to make thermal transfer t-shirts, which is what we still need to improve. I believe that we will be able to overcome this weakness in the near future.
