Knitted fabrics and woven fabrics have their own unique 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. The composition of fabric:
(A) Knitted fabric: the yarn is sequentially bent into loops, and the loops are intertwined to form a fabric. The process of forming loops by the yarns can be carried out horizontally or vertically. Horizontal knitting is called weft knitting, and longitudinal knitting It is called warp knitted fabric.
(B) Woven fabric: It is made of two or more sets of mutually perpendicular yarns interlaced with warp and weft at a 90 degree angle. The longitudinal yarns are called warp yarns, and the horizontal yarns are called weft yarns.

2. The basic unit of fabric organization:
(A) 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 spatial curve.
(B) Woven fabric: Every intersection point between warp and weft is called the weave point, which is the smallest basic unit of woven fabric.

3. Fabric weave characteristics:
(A) 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 loop The height of the loop is also increased, while the width of the loop is reduced. If the tension is horizontally stretched, the situation is the opposite. The height and width of the loop are obviously interchangeable under different tension conditions, so the stretchability of the knitted fabric is large.
(B) Woven fabric: Because the warp and weft interlace are 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 and the yarn stiffness. External tension, for example, when stretched in the longitudinal direction, the tension of the warp yarn will increase and the bending will decrease, while the bending of the weft yarn will increase, such as stretching in the longitudinal direction until the warp yarn is completely 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 fully straightened, and the fabric shrinks longitudinally. The warp and weft will not change, which is different from knitted fabrics.
