LIGHT-BLOCKING FABRIC AND MANUFACTURING METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2019/146887
Kind Code:
A1
Abstract:
The present invention relates to: a light-blocking fabric usable in blinds for light blocking or wind protection; and a manufacturing method therefor, the light-blocking fabric comprising: two blocking parts which is made of a non-transparent fabric; and a transparent part located between the two blocking parts, and attached to a location that is at least half of one surface of the blocking parts so as to overlap therewith in the longitudinal direction, wherein the blocking parts and the transparent part can be attached by various methods such as hot melting, an adhesive, sewing or ultrasonic welding. The method for manufacturing a light-blocking fabric comprises: (a) a first injection step of unwinding two blocking part fabrics wound in a roll form, and injecting the same into a fabric processing apparatus; (b) a coating step of coating, with an adhesive, the position of a half or more of any one surface of the two blocking part fabrics in the longitudinal direction while the two blocking part fabrics move along a guide part of the fabric processing apparatus; (c) a second injection step of unwinding a mesh fabric wound in a roll form, horizontally arranging and injecting the same into the fabric processing apparatus such that the same overlaps between the two blocking part fabrics on which the adhesive is coated in the coating step; (d) a manufacturing step of manufacturing a light-blocking fabric by attaching, to the mesh fabric injected in the second injection step, the two blocking part fabrics on which the adhesive is coated in the coating step along the guide part of the fabric processing apparatus; and (e) a winding step of winding, in a roll form, the light-blocking fabric manufactured in the manufacturing step.
