What kind of hem finish is the 'turn-back bonding' often seen in pants descriptions?
While browsing pants products, I noticed that 'turn-back bonding' was commonly written in the hem descriptions of different garments, so I became curious about its characteristics.
It is a finish where the edge of the fabric is folded inward and bonded instead of sewn with thread, creating a clean look without visible stitching marks on the outer surface.
Looking at JEONGLI's pants lineup, the same finishing method repeatedly appears at the hems. KARMAN Slacks Grey (KARMAN 슬랙스 그레이) finishes its hem with turn-back bonding[1], and Softshell Slash Trousers Matcha (소프트쉘 슬래시 트라우저 말차) also applies a turn-back bonding design to the hem[2]. Both pants, which differ in fabric and purpose, chose the method of folding and bonding the inside of the hem when finishing the edge.
Turn-back refers to folding the edge of the fabric inward, and bonding refers to processing where fibers are joined together using heat or adhesive tape. Unlike conventional blind-stitch sewing that secures the hem with thread, its characteristic is that no needle marks or stitches show on the outer surface.
Because stitches are not visible on the outside, the trouser line extending from the waist to the ankle connects smoothly without interruption. Additionally, the folded area is firmly held by the bonded surface, preventing the hem from flipping over or flapping while walking, and helping maintain a neat silhouette by falling straight over shoes.
The specific ingredients of the adhesive material or detailed specifications for the bonding width used in the hem turn-back bonding process have not yet been confirmed.
