PURPOSE: A roll-up shade is provided to alternately arrange an aluminum plate and a metallic wire as transverse yarn and determine the width of a roll with a unit aluminum plate by weaving using polyester yarn as longitudinal yarn. CONSTITUTION: A roll-up shade is as follows. Weaving is made using an aluminum plate(1) as transverse yarn and polyester yarn(3) as longitudinal yarn. The aluminum plate has a lot of holes(2) and is formed as 0.5-1.5mm in thickness and 10-25mm in width. A metallic wire(4) is arranged as transverse yarn between the aluminum plates and polyester yarn is used as longitudinal yarn. The width of a roll by a unit aluminum plate is determined. The metallic wire represents the clear boundary of the roll.
