What are the obvious differences between fabrics
Differences between knitted fabrics and woven fabrics Knitted fabrics and woven fabrics have their own unique characteristics in terms of processing technology, fabric structure, fabric characteristics, and finished product uses due to different weaving methods. Here are some comparisons.
1. The composition of the fabric structure:
(1) Knitted fabric: the yarn is sequentially bent into coils, and the coils are intertwined to form a fabric, and the process of forming the coils from the yarns can be carried out horizontally or vertically. It is weft knitted fabric, and longitudinal knitted fabric is called warp knitted fabric.
(2) Woven fabric: It is a fabric made of two or more sets of mutually perpendicular yarns interwoven at a 90-degree angle for warp and weft. The longitudinal yarns are called warp yarns, and the horizontal yarns are called weft yarns.
2. Basic unit of fabric organization:
(1) Knitted fabric: The loop is the smallest basic unit of the knitted fabric, and the loop is composed of the loop stem and the extension line in a space curve.
(2) Woven fabric: Each intersection point between warp and weft is called a weave point and is the smallest basic unit of a woven fabric.
3. Characteristics of fabric organization:
(1) Knitted fabric: Because the loop is formed by the bending of 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 loop The bending of the coil changes, and the height of the coil increases, while the width of the coil decreases. If the tension is transversely stretched, the situation is the opposite. The height and width of the coil can obviously be converted to each other under different tension conditions. Therefore, knitting The extensibility of things is large.
(2) Woven fabric: Because the warp and weft yarns are intertwined with some bending, and the moraine is bent in the direction perpendicular to the fabric plane, the degree of bending is related to the mutual tension between the warp and weft yarns, as well as the yarn stiffness. When the woven fabric is subjected to External tension, such as longitudinal stretching, the warp tension increases, the bending decreases, and the weft bending 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.
4. Characteristics of fabric structure:
(1) Knitted fabric: 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.
(2) Woven fabric: Because the warp and weft of the woven fabric have little relationship with the shrinkage, and no conversion occurs, the fabric is generally relatively tight and stiff.
5. Physical and mechanical properties of fabric structure:
(1) Knitted fabrics: physical and mechanical properties of fabrics, including vertical density, horizontal density, square gram weight, elongation, elasticity, breaking strength, abrasion resistance, curling, Thickness, release, shrinkage, coverage, bulk density.
(2) Woven fabrics: Physical and mechanical properties of woven fabrics, including warp and weft yarn density, selvedge, front and back, forward and reverse wool directions, and fabric coverage.
