System for injecting functional solution for fabric and method for manufacturing fabric using same

A system for injecting a functional solution for fabric, comprising:

• a first supply portion provided with a supply roll for winding fabric;
• a second supply portion provided with a tank for manufacturing a functional solution by mixing functional materials having insulation, waterproofing, antifouling, antibacterial, and/or flame retardant properties with solvents, and a distributing device for discharging the functional solution stored in the tank;
• an injection portion provided with a needle for injecting the functional solution supplied from the distributing device to inside the fabric transferred from the first supply portion, wherein the injection portion further comprises:
• a supporting member arranged across the direction of progress of the fabric;
• a first robot installed at both ends of the supporting member so that the supporting member moves reciprocally backward and forward with respect to the direction of progress of the fabric;
• a second robot mounted on the supporting member;
• a needle block mounted on the lower part of the second robot configured to move upward and downward by the second robot;
• a needle valve mounted on the needle block and configured to receive the functional solution from the distributing device;
• and
• a needle socket mounted with the needle, the needle socket installed on the needle block to introduce the functional solution received from the needle valve and passing through the needle block;
• a drying portion provided with a hot air blower or a blower for discharging hot air of a temperature higher than a boiling point of the solvent in order to evaporate the solvent from the fabric passing through the injection portion;
• and
• a collection portion provided with a collecting roll for winding the fabric passing through the drying portion.
