Textile Engineering · Knitting Technology

Consider the following statements regarding the structural terminology and construction parameters of knitted fabrics: I. A wale represents a predominantly vertical column of loops propagating in the lengthwise direction of a knit fabric, structurally corresponding to the warp direction in woven fabrics. II. A course is defined as a predominantly horizontal row of loops extending widthwise from one side to the other, structurally corresponding to the weft direction in woven textiles. III. In the structural analysis of a knitted textile, a specimen displaying 36 loops per inch horizontally and 48 loops per inch vertically categorically translates to a construction of 48 courses and 36 wales per inch. IV. Stitch density is calculated by determining the product of wales per inch and courses per inch. Which of the statements given above are correct?
