How to distinguish knitted fabrics and woven fabrics?

At present, most of the fabrics in my country's knitted fabric manufacturers are divided into knitted and woven fabrics. Woven fabrics are fabrics formed by weaving warp yarns and weft yarns perpendicular to each other. Knitted fabrics are made by forming loops of yarn or filaments with knitting needles, and then stringing the loops into each other. Today we will introduce the difference between the two.

"Knitted fabrics and woven fabrics have their own characteristics in terms of processing technology, fabric structure, fabric characteristics, and use of finished products due to different weaving methods. 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 yarns, and then connect them to form a knitted fabric. It can be done transversely or longitudinally, transverse knitting is called weft knitting, and longitudinal knitting is called warp knitting.

The loop is the small basic unit of the 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 with warp and weft at a 90 degree angle. The longitudinal yarns are called warp yarns, and the transverse yarns are called weft yarns.

Each intersection point between the warp and weft is called the weave point, which is the small basic unit of the woven fabric.

2. Fabric weave characteristics

Knitted fabric:

Because the loops are formed by bending the yarn in space, and each loop is composed of one yarn, when the knitted fabric is subjected to external tension, such as longitudinal stretching, the bending of the loop changes and the height of the loop increases. The width of the loop is reduced. If the tension is horizontal stretching, the situation is reversed. Under different tension conditions, the height and width of the loop can obviously be converted to each other, so the stretchability of the knitted fabric is large.

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 a soft feel.

Woven fabric:

Because the place where the warp and weft interweave is somewhat bent, 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 yarns and the yarn stiffness. When the woven fabric is subjected to external tension, such as longitudinal When stretching, the tension of the warp yarn increases and the bending decreases, while the bending of the weft yarn increases, such as longitudinal stretching continuously until the warp yarn is straightened, and the fabric shrinks in the transverse direction. When the woven fabric is stretched transversely by external tension, the tension of the weft yarn increases, the bending decreases, and the warp yarn bending increases, such as the transverse stretching continues until the weft yarn is straightened, and the fabric shrinks longitudinally. The warp and weft will not be converted, which is different from knitted fabrics.

The warp and weft yarns of the woven fabric have little relationship with the extension and contraction, and no conversion occurs. Therefore, the fabric is generally tight and stiff.
