Terry Towelling and Loop Pile Constructions
topic
Terry towelling uses an uncut loop pile formed by a specially controlled pile warp delivered at high overfeed ratio of 3:1 to 5:1 relative to ground warp, with the pile loops formed by the fast advancing pile warp against a periodically retarded fell position that allows pile loops to project from both fabric faces, producing the characteristic loop pile surface of towelling with pile height of 3 to 8 millimetres governed by the difference between pile warp delivery speed and ground warp take-up rate.
Role
Produces the high-absorbency loop pile surface of terry towelling through the mechanical interaction between pile warp overfeed and the periodic beating mechanism that forms pile loops, with terry construction being the most direct application of extra warp pile principles to commercial absorbent textile production where the uncut loop pile provides greater surface area for water absorption than cut pile at equivalent pile density and height.
