Warp knitting is defined as a loop-forming process in which the yarn is fed into the knitting zone, parallel to the fabric selvage. It forms vertical loops in one course and then moves diagonally to knit the next course. Thus the yarns zigzag from side to side along the length of the fabric. Each stitch in a course is made by many different yarns. Each stitch in one wale is made by several different yarns.
Basic pattern of warp knitting. Parallel yarns zigzag lengthwise along the fabric, each loop securing a loop of an adjacent strand from the previous row.

Elisabeth Félix, better known only as Mademoiselle Rachel or simply Rachel, was a French actress. She became a prominent figure in French society, and was the mistress of, among others, Napoleon III, Prince Napoléon, and Alexandre Colonna-Walewski, the illegitimate son of Napoleon I. Efforts by newspapers to publish pictures of her on her deathbed led to the introduction of privacy rights into French law.
