This solution determines the loop density per square centimeter for a knitted fabric using the provided loop length, wale constant, and course constant.
Loop density ($D$) is the number of loops per unit area. For this calculation, using the given constants, the relevant formula is:
$ D = \frac{K_w \times K_c}{L^2} $
Where:
Identify Given Values:
Calculate Loop Length Squared:
$ L^2 = (0.5 \text{ cm})^2 = 0.25 \text{ cm}^2 $
Apply the Formula:
Substitute the known values into the formula:
$ D = \frac{4.2 \times 5.5}{0.25 \text{ cm}^2} $
Calculate the Numerator:
$ D = \frac{23.1}{0.25 \text{ cm}^2} $
Compute the Density:
$ D = 92.4 \text{ loops/cm}^2 $
Round to Nearest Integer:
Rounding $92.4$ to the nearest integer gives $92$.
The calculated loop density is 92 loops/cm$^2$.
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______.
