The question asks about the characteristics of knitting fabrics based on the type of loop formed: a standard knit loop versus a tuck loop.
In knitting, loops of yarn are interconnected to form fabric. The primary loop structure is the 'knit loop'. A 'tuck loop' is a variation where the yarn doesn't fully form a new loop but rather 'tucks' behind an existing loop on the needle from a previous course.
Let's analyze the impact of tuck loops compared to knit loops:
Because tuck loops consume more yarn and create a bulkier stitch structure by holding loops back, the resulting fabric is denser and thicker than a fabric made solely with knit loops under similar conditions.
The less compact structure formed by tuck loops tends to spread the stitches out more horizontally. This means that for a given number of wales (columns of stitches), a fabric with tuck loops will be wider than one made purely with knit loops.
Based on this analysis:
Therefore, the correct statements highlight that a fabric with tuck loops is both wider and thicker.
A circular weft knitting machine with 24 inch gauge and 20 inch diameter needle bed is used to make a tubular knitted fabric. If the fabric shrinks by 35 % in course-wise direction upon withdrawal from the machine, the circumference (inch) of the shrunk tubular fabric is approximately
Group I gives a list of terms related to woven fabrics and Group II contains equivalent terms related to knitted fabrics. Match the term from Group I with the equivalent term from Group II.
| Group I | Group II |
| P. Cover | 1. Interlock |
| Q. Double-cloth | 2. Wales |
| R. Warp | 3. Tightness |
| S. Weft | 4. Courses |
The wale constant and course constant are 4.2 and 5.04 respectively. If the loop length is 4.2 mm, then stitch density (number/cm$^2$) is______.
