Abstract[English]
A projection screen (10), a preparation method for the projection screen (10), a projection system and a vehicle. The projection screen (10) comprises a black base fabric layer (11), a black flexible undercoating layer (12) and a white flexible surface layer (13) which are sequentially stacked; the black base fabric layer (11) comprises a loop structure, a weft insertion structure and a fabric stiffening agent; the loop structure is formed by weaving a ground yarn (11a); the weft insertion structure is formed from a weft insertion yarn (11b) inserted in the weft direction into the loop structure; the fabric stiffening agent fills gaps between the ground yarn (11a) and the weft insertion yarn (11b); the ground yarn (11a) is made of polyester and a fiber reinforced material; and the weft insertion yarn (11b) is made of glass fibers.[French]
L'invention concerne un écran de projection (10), un procédé de préparation de l'écran de projection (10), un système de projection et un véhicule. L'écran de projection (10) comprend une couche de tissu de base noir (11), une couche de sous-revêtement flexible noir (12) et une couche de surface flexible blanche (13) qui sont empilées de manière successive ; la couche de tissu de base noir (11) comprend une structure de boucle, une structure d'insertion de trame et un agent de raidissement de tissu ; la structure de boucle est formée par le tissage d'un fil de fond (11a) ; la structure d'insertion de trame est formée à partir d'un fil d'insertion de trame (11b) qui est inséré dans la structure de boucle dans le sens de la trame ; l'agent de raidissement de tissu remplit les espaces entre le fil de fond (11a) et le fil d'insertion de trame (11b) ; le fil de fond (11a) est constitué de polyester et d'un matériau renforcé par des fibres ; et le fil d'insertion de trame (11b) est constitué de fibres de verre.[Chinese]
