Study Notes
Carding Process
- The primary objective of the carding process is to align and clean the cotton fibers.
- One of the objectives of cleaning the cotton completely in the carding process is to remove impurities and dirt.
- Converting cotton into a regular, round strip in the carding process aims to achieve uniformity and orientation of fibers.
- The purpose of eliminating a specific percentage of very short cotton fibers in the carding process is to improve the strength and quality of the fibers.
Raschel Machines
- The gauge of Raschel machines is expressed by the number of needles per inch.
- Raschel machines typically have two warp groups and four bar guides.
- The function of the sinker in Raschel stitch formation is to form loops and guide the yarn.
- The primary characteristic of fabric structures produced on Raschel machines is their warp-knitted structure.
- During step 5 of Raschel stitch formation, the needle inserts the yarn into the existing loops to form a new loop.
