How to distinguish knitted fabrics from woven fabrics?

Date of release:2019-04-16 Author: Click:

At present, most of the knitted fabrics in China are divided into knitting and shuttle fabrics. Shuttle fabric is a fabric that interweaves warp yarn and weft yarn vertically. Knitted fabrics are made of yarns or filaments which are coiled by knitting needles and then coiled in series with each other. Today we will introduce the difference between the two.

"Knitted fabrics and shuttle fabrics have their own characteristics in terms of processing technology, fabric structure, fabric characteristics and finished product use, due to their different knitting methods.

1. Basic concepts

Knitted fabrics:

Knitting refers to the process of making coils of yarns of various raw materials and varieties by knitting needles and then connecting them into knitted fabrics through series. It can be done horizontally or vertically. Lateral braiding is called weft braiding, while vertical braiding is called warp knitting.

The coil is the small basic unit of knitted fabric, and the coil consists of a space curve of the loop stem and the extension line.

Shuttle fabrics:

Shuttle weaving is a fabric made of two or more sets of mutually perpendicular yarns interwoven at 90 degrees of warp and weft. Longitudinal yarn is called warp yarn and transverse yarn is called weft yarn.

Each intersection point between warp and weft yarn is called weaving point, which is the small basic unit of shuttle fabric.

2. Texture characteristics of fabrics

Knitted fabrics:

Because the coil is formed by bending the yarn in space, and each coil consists of a single yarn. When the knitted fabric is subjected to external tension, such as longitudinal tension, the bending of the coil changes, while the height of the coil increases, while the width of the coil decreases. If the tension is transverse tension, on the contrary, the height and width of the coil. Under different tension conditions, it is obvious that knitted fabrics can be converted to each other, so the extensibility of knitted fabrics is great.

It can extend in all directions and has good elasticity. Knitted fabrics are formed by porous coils, which have great air permeability and soft handle.

Shuttle fabrics:

Because warp and weft interweave somewhat bent, and loops bend in the direction perpendicular to the fabric plane, the degree of bending is related to the tension between warp and weft, and yarn stiffness. When shuttle fabric is subjected to external tension, such as longitudinal tension, warp tension increases, warp bending decreases, while weft bending increases. In addition, if the longitudinal tension does not stop until the warp stretches, while the fabric shrinks horizontally. When shuttle fabrics are drawn horizontally under external tension, the weft tension increases while the warp bending decreases, while the warp bending increases, such as the transverse tension does not stop until the weft stretches, while the fabric shrinks longitudinally. Warp and weft will not change, unlike knitted fabrics.

The warp and weft extensions of shuttle fabrics have little relation with shrinkage and do not change, so the fabric is generally compact and stiff.

3. Fabric properties

Wear Resistance-Knitted Fabric <Shuttle Fabric

Stretchability - Knitted Fabric > Shuttle Fabric

Comfort - Knitted Fabric > Shuttle Fabric

Warmth retention - knitted fabrics > shuttle fabrics

Air Permeability - Knitted Fabric > Shuttle Fabric

Tear Strength - Knitted Fabric > Shuttle Fabric

Anti-fuzzing and pilling-knitted fabric <shuttle fabric

Dimensional Stability-Knitted Fabric <Shuttle Fabric

4. Application

Knitted fabrics: T-shirt, T-shirt, sportswear, sweater.

Shuttle fabrics: shirts, suits, down clothes, jeans.
