Many people confuse seamless underwear with adhesive (hot pressed) underwear, and the core difference between the two lies in the molding process, with emphasis on wearing comfort and durability.
Seamless underwear adopts the integrated knitting process of cylindrical circular knitting machine, and the yarn is directly woven into a cylindrical body. The main body of the pants has no side seams, and the waist and hip elasticity and shape are shaped by the weaving method changes, belonging to the whole piece fabric forming. The fabric has uniform elasticity, strong structural stability, is not easy to peel off after washing, is wear-resistant and durable, and is more suitable for sports and long-term daily wear. The waist and leg edges can be cut normally or paired with hot pressed locking edges. The disadvantage is that the fabric selection is limited, and the ultra-thin and ultimate invisible effect is slightly weaker than the adhesive version.
Adhesive underwear (hot press seamless) is a process of cutting multiple pieces of fabric, followed by laser trimming and TPU hot melt adhesive film hot press bonding. It does not require needle and thread splicing, and the edges are extremely thin and light. When wearing tight skirts or yoga pants, the contours are almost invisible, and the invisible effect is outstanding. The fabric is made of ice silk, nylon, and spandex, providing a smooth and bare feel. The weakness lies in the adhesive film bonding at the joint. Long term high-temperature washing and strong twisting can easily cause poor quality products to peel off, and the aging of the adhesive layer can affect its use.
Summary
Seamless is a woven one-piece pants that excels in durability and stable elasticity; Adhesive bonding is the process of hot pressing and bonding cut pieces, with a focus on ultimate invisibility. When making a purchase, you can choose according to the dressing scene, pursue invisible adhesive, and prioritize seamless styles for durable and sporty wear.
