SUNSCREEN BLIND FABRIC USING UNCOATED PLY YARNS, METHOD FOR WEAVING SAME, AND SUNSCREEN BLIND CONSISTING OF SUNSCREEN BLIND FABRIC

The present invention relates to a method for weaving a sunscreen blind fabric using uncoated ply yarns. The purpose of the present invention is to provide a method for weaving a sunscreen blind fabric, a sunscreen blind fabric, and a sunscreen blind, the method using warps and wefts being formed of uncoated ply yarns and having different low-melting point yarn mixture ratios so that the migration, unweaving, chalking and drapability of the sunscreen blind can be improved and the method utilizing a plain weave which uses a two-ply body free of warp overlapping and twisting so as to achieve an openness factor of 3% or greater (less than 4%). The sunscreen blind fabric of the present invention is woven in the form of a plane weave by warps and wefts, and the warps and wefts are formed of uncoated yarns and are mixed with low-melting point (LM) yarns at different ratios. The warps are mixed with the LM yarns at a ratio in which the thickness of the LM yarn in a warp thickness D1 is 0.05 D1 to 0.08 D1, and the wefts are mixed with the LM yarns at a ratio in which the thickness of the LM yarn in a weft thickness D2 is 0.20 D2 to 0.3 D2. The LM yarn mixture ratio is controlled such that the total proportion of the LM yarns in the woven fabric is maintained within a range of 10 to 20 volume% and also a difference between the thicknesses of the warps and wefts does not exceed 20%. Accordingly, a sunscreen blind fabric, which can ensure an openness factor to be less than 4% and improve migration, unweaving, chalking, and drapability, can be woven. La présente invention concerne un procédé de tissage d'un tissu de store de protection solaire utilisant des fils retors non revêtus. L'objet de la présente invention est de fournir un procédé de tissage d'un tissu de store de protection solaire, un tissu de store de protection solaire, et un store de protection solaire, le procédé utilisant des chaînes et des trames formées de fils retors non revêtus et ayant des rapports de mélange avec des fils à bas point de fusion différents de telle sorte que la migration, le détissage, le farinage et la souplesse du store de protection solaire peuvent être améliorés et le procédé utilisant une armure toile qui utilise un corps bicouche exempt de chaîne se chevauchant et en torsion de façon à obtenir un facteur d'ouverture de 3 % ou meilleur (inférieur à 4 %). Le tissu de store de protection solaire de la présente invention est tissé sous la forme d'une armure plane par des chaînes
