2.4 Yarn Spinning
The extracted lotus fibers were spun on box (peti) Charkha. Spinning of yarns was
done by Mr. Bakul Shah at Sardar Bhavan Trust, Vadodara. Thus, handspun yarns
were prepared.
Extracted fibers were wounded on pern. The spinner first sets the charkha. To
start the spinning process, the researcher slowly unwound the extracted fiber from
the pern and the spinner hold the fiber from right hand taking the fiber forward toward
the point of spindle. The spindle rotated; meanwhile, spinner also rotates the main
wheel from left hand in clockwise direction. The twisted yarn was collected on the
spindle and later winded on a wooden winder and hanks were prepared as shown in
Fig. 4.
2.5 Yarn Testing
Based on standard test method ASTM-D 885 [12], yarn testing was done at the testing
lab of Century Rayon (under the management and operation of Grasim Industries
Limited, Shahad, Mumbai).
2.5.1 Determination of Yarn Fineness
Using direct system of yarn numbering, denier of the yarn was determined by using
motorized wrap reel. 90 m of yarn was winded on wrap reel. The hank was taken out
from the reel and weighed on digital balance.
