The invention relates to the technical field of 
digital printing T-shirts, and discloses a preparation process of a ventilated and breathable 
digital printing T-shirt, which is characterized by comprising the following steps: preparing raw materials: preparing 120-150g of cotton 
fiber, 10-20g of spandex 
fiber, 20-40g of 
polyester fiber and 10-20g of 
viscose acetal fiber, preparing the T-shirt: preparing 120-150g of cotton fiber, 10-20g of spandex fiber, 20-40g of 
polyester fiber and 10-20g of 
viscose acetal fiber, and preparing the T-shirt by uniformly mixing the raw materials with the cotton fiber, the spandex fiber, the 
polyester fiber and the 
viscose acetal fiber; 20-40 g of polyester fibers and 10-20 g of viscose fibers are made into the T-shirt through a conventional technology, and 
pattern selection is conducted, specifically, a webpage is browsed on a computer, a pattern which finally needs to be printed is selected, then the pattern is edited, and the final pattern is made. According to the preparation process of the ventilated and breathable 
digital printing T-shirt, by arranging the 
air purification device, peculiar smell generated during ink jetting can be filtered and purified, in this way, the process has the peculiar smell removal function, the generated peculiar smell can be adsorbed and filtered when ink jetting is conducted on the T-shirt, the air quality of a workshop is improved, and the production cost is reduced. And the damage to the body health of workers is reduced.
