How to distinguish knitted fabrics and woven fabrics?

At present, the vast majority of fabrics in my country are divided into knitted and woven. Woven fabric is a fabric formed by intertwining the warp and weft yarns perpendicularly to each other. Knitted fabrics are formed by knitting needles to form loops of yarn or filaments, and then the loops are strung together. Today we will introduce the difference between the two.

"Due to the different weaving methods of knitted fabrics and woven fabrics, they have their own unique characteristics in terms of processing technology, fabric structure, fabric characteristics, and finished product uses. Here are some comparisons.

1 Basic Concepts

Knitted fabric:

Knitting refers to the process of using knitting needles to form loops of various raw materials and varieties of yarn, and then connecting them into knitted fabrics through strings. It can be done transversely or longitudinally, transverse weaving is called weft knitted fabric, and longitudinal weaving is called warp knitted fabric.

The loop is the smallest basic unit of knitted fabric, and the loop is composed of the loop stem and the extension line in a space curve.

Woven fabric:

Woven is a fabric made of two or more sets of mutually perpendicular yarns interwoven at a 90-degree angle for warp and weft. Longitudinal yarns are called warp yarns, and horizontal yarns are called weft yarns.

Each intersection point between warp and weft is called a weave point and is the smallest basic unit of a woven fabric.

2. Fabric weave characteristics

Knitted fabric:

Because the coils are formed by bending yarns in space, and each coil is composed of one yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the coils changes, and the height of the coils also increases. The width of the loop is reduced. If the tension is transversely stretched, the situation is the opposite. The height and width of the loop can obviously be converted to each other under different tension conditions, so the knitted fabric has great extensibility.

It can extend in all directions and has good elasticity. Because the knitted fabric is formed by hole-shaped loops, it has greater air permeability and feels soft.

Woven fabric:

Because the place where the warp and weft are intertwined is somewhat curved, and the moraine is bent in the direction perpendicular to the plane of the fabric, the degree of bending is related to the mutual tension between the warp and weft, and the stiffness of the yarn. When the woven fabric is subjected to external tension, such as longitudinal direction. When stretching, the tension of the warp increases, the bending decreases, and the bending of the weft increases, such as longitudinal stretching, until the warp is completely straightened, and the fabric shrinks laterally. When the woven fabric is stretched laterally by external tension, the tension of the weft yarn increases, the bending decreases, and the warp yarn bending increases, such as the lateral stretching continues until the weft yarn is completely straightened, and the fabric shrinks longitudinally. The warp and weft yarns do not change, unlike knitted fabrics.

The warp and weft extension of woven fabrics have little relationship with shrinkage and do not change, so the fabrics are generally tight and stiff.
