Abstract
The present invention relates to: a light-blocking fabric usable in blinds for shading or wind protection; and a manufacturing method therefor. The light-blocking fabric including: two light-shielding parts which are made of a non-transparent fabric; and a light-transmitting part located between the two light-shielding parts, and attached to a position that is at least half of any one surface of the light-shielding parts so as to overlap therewith in the longitudinal direction, wherein the light-shielding parts and the light-transmitting part can be attached together by various methods such as hot melting, an adhesive, sewing, or ultrasonic welding.
Claims6
A manufacturing method for a light-blocking fabric, the manufacturing method comprising:
- (a) a first injection step of unwinding two light-shielding part fabrics wound in two separate roll forms, respectively, and injecting the two light-shielding part fabrics into a fabric processing apparatus in a longitudinal direction;
- (b) a coating step of coating an adhesive onto at least half of a width of each of the two light-shielding part fabrics in the longitudinal direction while the two light-shielding part fabrics move along a guide part of the fabric processing apparatus;
- (c) a second injection step of unwinding a light-transmitting mesh fabric wound in a roll form, horizontally arranging, and injecting the light-transmitting mesh fabric into the fabric processing apparatus in the longitudinal direction such that the light-transmitting mesh fabric overlaps each of the two light-shielding part fabrics on which the adhesive has been coated in the coating step in the longitudinal direction;
- (d) a manufacturing step of manufacturing the light-blocking fabric by attaching, to the light-transmitting mesh fabric injected in the second injection step, the two light-shielding part fabrics on which the adhesive has been coated in the coating step such that two opposite sides of an inner surface of the light-transmitting mesh fabric at both ends in a width direction thereof are attached to the two light-shielding part fabrics, respectively, wherein the longitudinal direction is perpendicular to the width direction, and wherein the light-transmitting mesh fabric starts bonding with each of the two light-shielding part fabrics at a position that is at least half of the width of each of the two light-shielding part fabrics;
- and
- (e) a winding step of winding, in a roll form, the light-blocking fabric manufactured in the manufacturing step about an axis perpendicular to the longitudinal direction, wherein the light-blocking fabric is not cut between the first injection step and the winding step.
