Non-woven bags are generally used screen printing process, which is often said that “silk screen”, which has also been a lot of manufacturers more commonly used printing process. Generally artificial printing, so the process of colour control is not good control, so the emergence of many new non-woven printing methods, where we introduce the current mainstream of the market several:
Because of its use of water-based rubber mortar as the printing medium and named in the textile printing more common, also known as printing. When printing the colour paste and water-based plastic glue to reconcile. Wash the plate without chemical solvents, can be washed directly with water. Its characteristics are good colouring ability, with strong cover and fastness, washable, basically no smell.
The finished product processed in this way is usually called non-woven bag. This process is divided into two steps, that is, the first use of the traditional gravure printing process will be printed on the film, and then use the coating process will be printed on the pattern of film composite in the non-woven fabrics. General large-scale colour pattern printing of non-woven bags are used in this process. Its characteristics are beautifully printed, full use of machine production, production cycle is short. In addition, the product has excellent waterproof performance, the durability of the finished product than other non-woven bags produced. A film with light and matter two options, matte scrub effect! The disadvantage is that there is a conflict with the concept of environmental protection because the film is difficult to degradation.
Thermal transfer in the printing is a special printing! The method requires an intermediate medium, i.e., the graphic is printed on the thermal transfer film or the thermal transfer paper, and the pattern is transferred to the nonwoven fabric by warming with the transfer apparatus. The medium commonly used in textile printing is a thermal transfer film. Its advantages are printing fine, rich version of the version, comparable to the photo. Suitable for small area colour image printing. The disadvantage is high prices, high printing costs.
