Abstract
A method of producing a knitted brief blank of flat form. First, a preliminary tubular blank including a comparatively narrow portion of crotch fabric is produced by seamless knitting. Then this tubular blank is slit and opened out flat into a final brief blank. The preliminary tubular blank in one form comprises two circular knitted tubular portions extending relatively at an angle and connected by an interposed elbow-like pouch formed by reciprocatory knitting on to the point of which is knitted a comparatively narrow selvedged loop of crotch fabric. Alternatively, the preliminary tubular blank may be wholly produced by circular knitting and comprise aligned opposite end portions and an intervening waisted portion of reduced diameter constituting narrowed crotch fabric.
