At present, most of China's fabrics are divided into knitted and woven. A woven fabric is a fabric formed by interlacing warp and weft perpendicularly to each other. Knitted fabrics are made by knitting needles to form yarns or filaments, and then stitching the coils to each other. Today we will introduce the difference between the two.

Knitted fabrics and woven fabrics have their own unique characteristics in terms of processing techniques, fabric structure, fabric properties, and finished products, due to their different methods of weaving, and some comparisons are made here mattress fabrics.

1, the basic concept

Knitted fabric:

Knitting refers to a process in which a yarn of various raw materials and varieties is formed into a loop by a knitting needle, and then connected into a knitted fabric through a string. It can be carried out laterally or longitudinally, the transverse weave is called weft knit, and the longitudinal weaving is called warp knit.

The coil is the smallest basic unit of the knitted fabric, and the coil is composed of a circle and a stretched line in a spatial curve.

Woven fabric:

Woven is a fabric in which two or more sets of mutually perpendicular yarns are interlaced at a 90 degree angle. The longitudinal yarn is called warp yarn, and the horizontal yarn is called weft yarn.

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

2, fabric texture characteristics

Knitted fabric:

Since the coil is a yarn which is bent 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 coil changes, and the height of the coil also increases, and at the same time The width of the coil is reduced. For example, the tension is transversely stretched. On the contrary, the height and width of the coil are obviously mutually convertible under different tension conditions, so that the stretchability of the knitted fabric is large.

It can be extended in all directions and has good elasticity. Because the knitted fabric is formed by a hole-shaped coil, it has a large air permeability and a soft hand feeling.

Woven fabric:

Since the warp and weft are interlaced somewhat, and the weir is bent in a 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 yarn stiffness, when the woven fabric is subjected to external tension, such as in the longitudinal direction. When stretched, the tension of the warp yarn increases, the bending decreases, and the bending of the weft yarn increases, such as longitudinal stretching, until the warp yarn is completely straightened, while the fabric shrinks laterally. When the woven fabric is stretched in the transverse direction by the external tension, the tension of the weft yarn is increased, the bending is reduced, and the warp yarn bending is increased, such as the transverse stretching, until the weft yarn is completely straightened, and the fabric is longitudinally contracted. However, the weft yarn does not change, unlike the knitted fabric.

The warp and weft stretches and shrinkage have little relationship and do not change, so the fabric is generally tight and quite hard.

3, fabric properties

Abrasion - Knitted fabric

Comfort - Knitted Fabric > Shuttle Fabric

Warmth - Knitted Fabric > Woven Fabric

Breathability - Knitted Fabric > Woven Fabric

Tear strength - knitted fabric > woven fabric

Anti-pilling pilling - knitted fabric < shuttle fabric
