Sewing Robot: See how the robot cooperates with the sewing m

Most of the work in garment making is still done by hand. Nowadays, some manufacturers intend to end this state of affairs.
Take a look at the labels on your clothes. If you are in the United States, then your clothes are probably made in China or Thailand and shipped to the United States.
Jonathan Zornow is the owner and sole employee of the startup Sewbo. He intends to take practical action, through the automation of the garment processing industry, so that the outflow of garment manufacturing industry gradually returned to the mainland.
At present, the work of feeding cloth to sewing machines is still done manually. Zornow designed a process for the manipulator to grab the specially hardened fabric and feed it to a commercial sewing machine.
In fact, in the fabric processing industry, mechanization has become the leading role.
According to Cynthia Istool, a textile/apparel researcher at North Carolina State University, fabrics are first woven mechanically and then cut on demand by computer-controlled cutting machines. In addition, there are some small garment parts, such as the collar cuffs of formal shirts, which can also be manufactured by machines.
However, the work of sewing these fabrics into a whole still depends on manual work. The worker puts the fabric into the sewing machine and delivers the stitched fabric to the next part of the assembly line.
Before founding Sewbo, Zornow was a programmer who was fascinated by highly automated mechanical projects. He has studied a water-soluble thermoplastic polymer material, which is often used as a raw material for 3D printing and is also commonly used in the textile industry.
Zornow realized that as long as soft cloth was immersed in molten polymers, hard fabrics could be produced automatically.
Before stitching, the fabric is "stitched" together by ultrasonic welding technology. After sewing, the finished clothes are immersed in water and the polymer "reinforcement" is washed off.
To complete this process, a spot sewing machine and a mechanical arm named UR5 are needed. The arm, built by Universal Robots, is priced at around $35,000. UR5 can perform specified tasks repeatedly. The setting process is very simple. It only needs to be taught once by hand
Zornow shows us how to sew a T-shirt. Of course, UR5 can also learn different behavioral patterns.
Clothing companies will open factories in countries and regions with low labor prices in pursuit of low costs.
In a 2011 report, the Center for American Progress pointed out that the average monthly wage paid to Chinese workers by the 15 major clothing importers in the United States was only 324.9 dollars (about 2166.5 yuan). Bangladesh's cheap labor earns less, with only $91.45 a month (about 609.8252 yuan).
By comparison, according to the Bureau of Labor Statistics, the average monthly salary of sewing machine operators in the United States is $1922 (equivalent to RMB 12816.66).
At present, Zornow is seeking like-minded business partners to work together to solve obstacles on the way forward. The company's goal is to set up a robotic production line, each robot has its own duties, cloth specialization.
Despite Zornow's claim that cloth hardening solvents can be reused, Istool still believes that this could lead to overuse of chemicals and water resources. With the addition of extra time-consuming production links, this will offset the cost and resource advantages of automation.
One of Sewbo's biggest selling points is that manufacturers can put new designs into mass production within a day. Following the traditional process, it takes months for a new design to be manufactured and transported. This advantage of Sewbo will certainly give a new meaning to the word "Fast Fashion".
