24—WORSTED 1 × 1 RIB FABRICS PART II. SOME PHYSICAL PROPERTIES

The effects of changes in loop length and yarn diameter on the physical proproperties of wet-relaxed fabrics are investigated, and the results are discussed with reference to the cover factors of the fabrics studied. The widthwise extension of 1 × 1 rib fabrics is examined in detail, and the model of the rib stitch obtained in Part I of this series1 is used in an attempt to account for the observed extension in terms of the properties of the yarn and the geometry of the fabrics.
