What are the advantages and disadvantages of knitwear and woven garments?

Knitwear and woven fabric difference

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.

(1) The composition of the fabric:

(A) Knitted fabric: the yarn is sequentially bent into a coil, and the coils are sleeved to form a fabric, and the process of forming the stitch of the yarn can be carried out laterally or vertically, the transverse weaving is called weft knitting, and the longitudinal weaving is It is called warp knit.

(B) woven fabric: It is made up of two or more sets of mutually perpendicular yarns, which are interlaced by warp and weft at a 90-degree angle. The longitudinal yarn is called warp yarn, and the horizontal yarn is called weft yarn.

(ii) Basic unit of fabric organization:

(A) Knitted fabric: 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.

(B) Woven fabric: Each point of intersection between warp and weft is called the tissue point and is the smallest basic unit of the woven fabric.

(3) Fabric structure characteristics:

(A) Knitted fabric: Since the coil is a yarn that is bent in space, 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 coil The height of the coil is also increased, and the width of the coil is reduced. For example, the tension is transversely stretched, and the opposite is true. 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.

(B) woven fabric: the warp and weft are interlaced with some curvature, and the crepe is bent in a direction perpendicular to the plane of the fabric, the degree of bending and the mutual tension between the warp and weft, as well as the yarn stiffness, when the woven fabric is affected External tension, such as stretching in the longitudinal direction, increases the tension of the warp, and the bending decreases, while the bending of the weft increases, such as longitudinal stretching, until the warp 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.

(iv) Characteristics of fabric organization:

(A) Knitted fabric: 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 touch.

(B) woven fabric: Due to the woven fabric, the weft extension and shrinkage have little relationship, and no conversion occurs. Therefore, the fabric is generally compact and quite hard.

(5) Physical and mechanical properties of fabric tissue:

(A) Knitted fabric: physical and mechanical properties of fabrics, including longitudinal density, transverse density, square gram weight, elongation properties, elasticity, breaking strength, abrasion resistance, curling, thickness, dispersibility, shrinkage, coverage Sex, bulk density.

(B) woven fabric: physical and mechanical properties of the woven fabric, including yarn density of warp and weft, hem, front and back, reverse wool direction, fabric coverage.
