In the traditional garment manufacturing process, garment pieces are stitched together. However, the thickness of the seams and the stitch marks can affect the comfort and aesthetics of knitted garments, especially tight-fitting and body-shaping ones. To address the discomfort and damage to the appearance caused by the stitching process in tight-fitting and body-shaping knitted garments (which were mainly undergarments at that time), the seamless knitting technology emerged as the times require.

The development of seamless clothing into outerwear is a future trend in the textile and apparel industry. Its product range has expanded from basic undergarments alone to include sports and outdoor clothing (such as beachwear, specialized sportswear, outdoor travel clothing, etc.), casual wear (such as home wear, pajamas, etc.), fashion clothing (youth clothing, urban wear, etc.), and specialized medical and health care clothing. The seamless clothing industry has become a huge market in the textile and apparel sector.

In 2023, the global underwear market reached a size of 450 billion US dollars, with products made using seamless technology accounting for approximately 18% of this total. As the world's largest underwear market, China saw the penetration rate of seamless underwear reach 25% in 2023, significantly higher than the global average. Driven by the growing consumer demand for comfort, functionality, and personalization, the seamless underwear market is expected to expand at an average annual growth rate of 12.3%.

An increasing number of Chinese enterprises are engaging in the production of seamless knitted products. Whether for domestic sales or foreign trade processing, China's seamless clothing market holds tremendous potential. The booming sales of seamless clothing have directly stimulated the development of the seamless knitted clothing industry both domestically and internationally. The 2026 Guangzhou International Seamless Textile and Apparel Industry Technology Exhibition will serve as a platform integrating industry exhibitions and technical exchanges.
