Core abstract: The scraping cloth is a kind of chemical synthetic material, which is thicker than ordinary lamp cloth. The front side of the knife scraping cloth is flexible and smooth, while the back side is rough, and the particles are thick and uneven. There are high-gloss surface and matte surface for the knife-scraping cloth, mainly due to different application ranges.

The PVC film formed on the upper and lower sides is used as the base material, and the optical fiber sticker is added between the double-sided PVC interlayers, and then a certain pressure is applied through the rotation of the hot roller, and the three-layer materials are combined and then cooled and formed. The main production method is knife scraping. Coating method, calendering method, bonding method (melting method), etc., with cloth base divided into four types: 320, 520, 530, 550

Features of scraping cloth:
1) High strength, good ductility, strong flexibility
This unique property makes this material widely used in the large-format high-end fine commodity market
2) The surface is smooth and has strong ink absorption
The chemical properties of the material determine that it has strong ink adsorption and can adhere with high strength under the condition of oily or water-based ink
3) Stable physical and chemical properties
Mainly manifested in anti-oxidation, acid and alkali resistance and severe cold resistance

Types of scraping cloth:
Originally, the special UV inkjet cloth is divided into two types: UV knife-scratched inner light cloth and UV knife-scratched outer light cloth (now two kinds of UV clip black double-sided spray knife scraping cloth & UV clip matte black bottom knife scraping cloth have been added), The main reason is that the scope of use is different.

Double-sided spraying, that is, there can be pictures on both sides, and because the material is black, the picture will not bleed under strong light and the picture will be misplaced.
Scraping cloth (black background): The surface is relatively smooth, and the material has certain toughness and is not easy to wrinkle. The black background knife scraping cloth has a certain light blocking property, and the light transmittance is only about 10%.
Knife scraping cloth (inner light): As the name implies, the picture quality is clearer when the light source is on the back of the screen
Knife scraping cloth (external light): suitable for external light boxes, such as spotlight billboards, the display effect will be perfect when the light is directly on the screen.
Scraping cloth (matte): The surface feels slightly rough, but the texture of the picture is strong.
