Frequently Asked Questions | FAQs

What is knotting in weaving?

Knotting in weaving textiles refers to the process of tying two or more yarns together to create a new length of yarn. Knotting can be done manually or with the help of a knotting machine.
In textile weaving, knots are typically used when a yarn runs out and needs to be replaced with a new yarn. The weaver can simply tie a knot between the two yarns, and then continue weaving with the new length of yarn. The knot is usually placed at the selvage edge of the fabric, where it will be less noticeable.
However, knots can also be a source of problems in weaving, especially if they are not tied properly or if they are tied in an area where they will be visible in the finished fabric. Knots can create bulk in the fabric, which can affect the drape and appearance of the finished product. They can also be more prone to breaking, which can result in a weaker fabric.
To minimize the negative effects of knotting in weaving, some weavers prefer to use techniques such as splicing or overlapping to join two lengths of yarn. Splicing involves fusing the ends of two yarns together using heat or a special adhesive, while overlapping involves weaving the new yarn into the fabric for a short distance before cutting off the old yarn. These techniques can create a smoother transition between the two lengths of yarn, resulting in a stronger and more uniform fabric.

What types of knots are used in the handloom sector?

In the handloom sector, different types of knots may be used depending on the specific weaving technique, yarn type, and desired effect. Some common types of knots used in handloom weaving include:
1.Square knot: This is a basic knot that is commonly used to tie two yarns together. It is made by tying an overhand knot and then tying another overhand knot in the opposite direction.
2.Weaver’s knot: This is a knot that is commonly used to join two yarns of different thicknesses or materials. It is made by tying a square knot and then tucking the loose ends of the yarn back through the knot to create a more secure join.
3.Bow knot: This is a simple knot that is commonly used to tie off the end of a length of yarn. It is made by creating a loop with the yarn and tying a simple knot with the two loose ends.
4.Slipped knot: This is a knot that is commonly used to create a decorative effect in the fabric. It is made by tying a simple knot and then pulling one of the yarn ends through the knot to create a loop.
5.Lark’s head knot: This is a knot that is commonly used to attach a length of yarn to a loom or other weaving tool. It is made by folding the yarn in half, placing the folded end over the loom or tool, and then pulling the two loose ends through the folded end to create a loop.
These are just a few examples of the types of knots that may be used in handloom weaving. The specific knots used will depend on the weaver’s preferences and the requirements of the weaving project.
