Mother Yarn And Mono Yarn For Warp Knitting
Mother yarn and mono yarn are two types of yarn used in warp knitting. The main difference between the two is their structure and composition.
Mother yarn is a type of yarn that is made up of multiple strands of yarn twisted together. The strands are twisted in a way that they form a rope-like structure. This type of yarn is used as the base yarn for warp knitting. It provides strength and stability to the fabric.
Mono yarn, on the other hand, is a single strand of yarn that is smooth and without any twists. It is used as the top yarn for warp knitting. Mono yarn provides a smooth surface to the fabric and enhances the appearance.
In warp knitting, mother yarn is placed on the warp beam and is used as the base yarn. Mono yarn is then threaded through the needles and is used as the top yarn. The needles move up and down, interlocking the two yarns to create the fabric.
Both mother yarn and mono yarn come in different materials such as cotton, wool, silk, and synthetic fibers. The choice of yarn depends on the desired properties of the fabric, such as drape, texture, and durability.
In summary, mother yarn and mono yarn are two types of yarn used in warp knitting. Mother yarn provides strength and stability, while mono yarn provides a smooth surface and enhances the appearance of the fabric. Both types of yarn come in different materials and are chosen based on the desired properties of the fabric.
