Warping Parameters Influence on Warp Yarns Properties: Part 2: Warp Yarn Material and Cone position on Warping Creel

Abstract

Dorgham ME

Warping is a low yield operation owing to the time needed for creeling; the creels are the frames on which the cones which feed the warper are pinned. The number of cones depends on the type of fabric to be produced. The yarns are wound side by side and parallel one another on the beam, Also keep in mind that the number of yarns per beam is in the hundreds or thousands and that there must, at least, be one supply package for each of these yarns, if possible with the same tension, so the cone position and their accessibility are two important factors for the operator.
This paper reports a study on producing 27 different material yarn samples by an indirect warping machine (Benninger, Ben-Ergotronic, Switzerland) used in part 1 with (V) shaped creel, the samples of the yarn manufactured from three different material (Cotton, Spun polyester and Polyacrylic) In addition, three different yarn count 30/2, 16/2, 8/2 Ne for cotton , spun polyester and 40/2, 28/2, 14/2 Nm for Polyacrylic yarns under the same yarn pressure, with three different distances between warping drum and cone position on warping creel 4 m, 8 m and 12 m with the same warping speed were tests measuring tensile strength and elongation.
The results of measurements of warp yarn under study for tensile strength and elongation for deferent warpmaterials and position of cone installation on warping creel for the properties of the yarn through laboratoryexperiments and make classification of preference for operating under different warping yarn conditions
