What is Yarn?
Yarns are the continuous, strands produced from a short and staple fibres. These materials vary in their sizes and texture and form a suitable for knitting, weaving or otherwise intertwining to form textile fabrics.
They are made from both natural and synthetic fibres.
Properties of Yarn
The properties of yarn are as follows:
- Plasticity
- Elasticity
- Elongation
- Strength variation in yarn
- Processing efficiency of yarn
- Twist variations
Types of Yarn
There are three main types of Yarns:
- Stapled
- Simple or complex
- Single or plied or cord
Yarns are usually twisted tightly by the rollers to hold the fibres together. The size, number and the weight of the yarn vary with the types of fibres from which they are produced. These yarns can be produced both from the natural or synthetic fibres.

Yarn to Fabric
The fabrics are the flexible materials, which consists of a network of natural or artificial fibres, produced by weaving cotton, nylon, jute, wool, silk, or other threads together.
The two common methods used for producing Fabrics are:
Knitting
It is a process of producing fabric by the joining or interlinking of loops of one set of yarn. Different fabrics including the T-shirts, Sweaters, coats, shawls are all produced by the process of Knitting.
Knitted fabrics are very popular and can be very easily produced either from the yarn or any other fibres including cotton, nylon, woollen and the polyester.
There are different types of knitting techniques and are produced both by computerized and machine-based knitting.

Weaving
It is a process of producing fabric by the interweaving of warp and weft yarn. It is mainly used to make woven fabrics. All Trousers are produced by the process of weaving.
There are two methods used for weaving the yarn:
- Lengthwise Weaving – In this method of weaving, the yarn is weaved up and down or lengthwise or longitudinal in the body of clothing. It is also called as the warp.
- Crosswise Weaving – In this method of weaving, the yarn is weaved across the body of clothing. It is also called as the weft or filling of yarns.
Types of Weaving
There are three basic types of weaving:
- Plain Weave – In this type of weaving, the yarn is weaved one above the other. This method of weaving is strong, durable and easy to sew. It is the most basic type of weaving used for fashion and furnishing fabrics.
- Twill Weave – In this type of weaving, the yarn is passed or glides over one or more yarns in the same direction.it is a type of diagonal parallel ribs. This method of weaving is durable, more attractive and wrinkle-free.
- Satin Weave – It is produced by the interweaving of warp and weft yarn. This type of weaving is characterized by four or more fill to give a smooth, shiny and droppable fabrics.
