Introduction to Carding Process

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.
