Abstract
Results are reported of a comparative evaluation of the properties of fabrics produced from the American-Egyptian Pima S-1, Egyptian Karnak, and a high strength Upland cotton, Hybrid Strain 330. Relationships of some fiber and yarn properties to fabric properties are shown. The reactions of fabrics woven from these cottons to chemical finishing treatments (mercerization, scouring, bleaching, and dyeing) are also discussed.
In general, it was found that the Pima S-1 cotton produced fabrics which were ap proximately equal in breaking and tearing strength to those made from Hybrid Strain 330 cotton and which were stronger than those made from Karnak. Grey fabrics made from Pima S-1 had higher elongation, greater resistance to flex abrasion, and better draping qualities than those made from the other two cottons. The finishing treat-- ments had varied effects on the fabrics, but in most cases those made from Pima S-1 re mained equal to or better than those made from the other cottons in the properties measured. Fiber and yarn properties were closely related to fabric properties.
