Men's Seamless Underwear Manufacturer
Nantong Tianhong Textile Technology Co., Ltd. is a China-based men's seamless underwear manufacturer and OEM/ODM factory. Since 2001, we have specialized in circular-knit seamless construction for men's underwear, combining advanced knitting technology with sustainable fabric development. Our range serves brands across Europe, North America, and China, with a focus on comfort, durability, and reduced friction for daily wear and active use.
Our Seamless Underwear Range
We produce a focused line of seamless men's underwear styles, each engineered for specific applications and consumer preferences. All styles are manufactured on circular knitting machines that create the garment in one piece, eliminating side seams and reducing material waste.
Men's Seamless Trunk

Recycled Spandex Trunk
Made with recycled spandex, this style supports sustainability goals without compromising stretch or recovery.
Knitted Jersey Trunk

Seamless Trunk Underwear

Each style can be customized in fabric blend, color, waistband type, and branding to align with your brand identity. Explore our Men's Seamless Underwear category for detailed product pages.
Application Fit and Process
Seamless underwear is particularly suited for sports, daily wear, and any application where friction reduction is critical. The absence of side seams eliminates pressure points, making these garments ideal for long hours of wear. Our manufacturing process uses circular knitting machines that produce the entire garment in one piece, reducing material waste and improving consistency.
We work with a range of fabrics, including organic bamboo, recycled nylon, recycled polyester, modal, and spandex blends. These materials are selected based on the desired properties: moisture-wicking, or high elasticity. Our R&D team continuously tests new blends to enhance performance and sustainability.

Our seamless underwear is produced to meet strict dimensional tolerances and performance criteria. We conduct in-house testing for fabric integrity, colorfastness, and elasticity. Key specifications include:
