Dongguan located in South China's Guangdong province known as the capital of China's garment industry to combat mounting competition, the industry, which is labor-intensive, has turned to technology. Most of the factory owners are planning to invest in robotic technology to increase the bottom line and end their struggle against rising labour costs and cutthroat competition.

Garment-making machines can be operated by fewer workers and this can cut costs by more than 30 percent as well as boosting productivity by 40 percent.

According to Chen Yaohua, chairman of Dongguan Association of Textile and Garment Industry, high-end garment machines have become popular with factory owners as they reduce spending on training skilled workers.

Most of the factories in Dongguan have installed high tech cloth-making machines imported from Germany, Italy, the US and Japan along with homegrown technology as clothing companies strive to recruit unskilled staff in the battle against cheaper rivals from Vietnam, Cambodia and Bangladesh.

Last year, the city's 520 manufacturers exported $7.5 billion worth of apparel products and fashion accessories, according to Huangpu Customs. This was a rise of 3.8 percent compared to 2013, but a far cry from 2008 when the city shipped goods worth $113 billion. In a bid to retain global market share, investment has increased and even skilled staff have been trimmed.

Although nearly all the garment factories in the city are equipped with different types of machines and levels of technology, many are still short of hands.

Wages have also become a problem. The average monthly salary of a garment worker soared to about 3,200 yuan ($516) in March, a 12 percent increase compared to the same period last year.

Part of the reason for the increase is that factory owners need to pay employees more for working extra shifts. This comes at a time when cheaper fashion products are rolling off the production lines in India, Pakistan, Vietnam, Cambodia and Bangladesh.

By introducing robotic technology in different workshops, a medium-sized factory can bring down its workforce from 1,200 to 800. They can also help prevent material waste and increase manufacturing accuracy.

Although this rush to bring in technology will not completely automate factories, the number of workers needed will be reduced as garment companies look at new ways to survive in a changing business landscape.

The switch will also help address the chronic labor shortage in the industry as China moves to more upmarket manufacturing. In Dongguan, the shortage of workers in the garment sector could last for another decade, said Yu Changyan, managing director of Huifeng Industry Co in Humen, Dongguan,. So, they are dependent on automation to make stable profits.

In the past two years, the industry has upgraded technology in factories as workers' pay started to climb. This has created a business opportunity for the Dongguan Humen International Garment Machinery Market, which is owned by Yu's company.

Since 2010, the subsidiary of Huifeng Industry has invested nearly 110 million yuan in the sector. Even though the shift is still in its early stage, it indicates a deeper economic motivation as it comes at a time when factory owners are depending more on machines to boost production.

There are 16 companies, such as Sanflag Fashion (Dongguan) Co Ltd, Joneaa Jeans Co Ltd and Hong Kong Sky Max Garment Ltd's Dongguan factory, involved in the high-tech automation side of the clothing industry. They have brought a comprehensive range of equipment from high-speed sewing machines, and printing and laser-cutting technology, to advanced production lines.

Nearly 80 percent of the companies specializing in automated production deal with Chinese brands, while the rest have expanded their reach to foreign firms.

According to Gao Yupeng, deputy secretary-general of Dongguan Association of Textile and Garment Industry, the rising demand for machines is just a part of China’s upgrading boom. In 2014, Dongguan Humen International Garment Machinery Market sold 102 million yuan worth of machines.
