Why Does Flexible Light Box Cloth Have This Series Of Advantages?

Why does flexible light box cloth have this series of advantages?Why so many flex banner manufacturers to product flexible light box? Based on a lot of experimental analysis and investigation and research, we found that this is mainly due to the special performance characteristics of light box cloth. The following is a simple summary of these performance characteristics Description.

1. High modulus and high strength
In the process of making the light box, the light box cloth must be tightened on the side frame of the light box, so the light box cloth is under certain tension.

In addition, wind power will also have a great impact on the light box cloth. Despite these external forces, the light box cloth still needs to remain stiff, so the light box cloth is required to have the characteristics of high modulus, high strength, and good dimensional stability, so that it is not prone to slack deformation.
The main factors affecting the modulus and strength of the light box cloth are the types and specifications of the yarns used, the organizational structure of the base cloth used, and the process conditions of the subsequent calendering process. Currently, high-strength polyester filament yarns are widely used, which have high modulus and strength. The organization structure is generally biaxial warp-knitted organization, which can give full play to the high modulus and high strength characteristics of yarn. On this basis, the use of appropriate formulas and reasonable control of the calendering process conditions can improve the overall modulus and strength of the film and the product.

2. High tear strength and burst strength
Flexible light box cloth needs high tearing and bursting strength to meet the strict requirements of design and processing. In order to prevent holes from being accidentally impacted and expanding to form large structural tears, high tear and burst strength are necessary.
The main factors affecting the tearing strength and bursting strength of the light box cloth are the specifications of the yarns used, the structure of the base fabric and the strength of the PVC film.

3. Bonding fastness between film and fabric
The adhesion of the film to the base fabric fibers is a very important quality indicator. In the actual use process, the light box cloth is subject to a certain tension due to tension, and it is also damaged by wind and other climatic factors. There will be a partial separation between the resin layer and the fabric layer and gradually expand, which will affect the light box cloth. Strong, light and so on. Therefore, the light box cloth is required to have high peel strength, that is, it has excellent bonding fastness. This is generally improved by adding a binder that has good affinity with polyester fabrics in the formulation.

What is PVC light box film?
Laying the legal light box cloth is to form the upper and lower layers of the PVC film, which are heated under the pressure of the heat roller and bonded with the light guiding fiber net in the middle, and then cooled to form. The biggest feature of this process is its excellent ink-jet ink absorption and strong color expression. Therefore, with the rise of large-scale inkjet printing, this kind of light box cloth has also brought unlimited vitality. At present, the market share of this kind of light box cloth in China has exceeded 70%.
