Distinguish knitted fabric, woven fabric and non-woven fabric

Fabric is a material commonly used in human life, which is a product created by combining fibrils by weaving or knitting or attaching multiple fibers to a fabric with a large surface to meet. Many different needs of use, with certain thickness and strength.

In general, the 3 basic processes that produce fabrics are classified as follows:
Woven:

Weaving is the process of creating a combination of two warp systems: warp and warp (weft) perpendicular to each other. In which, depending on the different weaving styles, the weft will be knit with warp yarns with different specifications to create different types of weaving. The yarn that is run vertically (lengthwise) of the fabric (Woven fabric), called the warp yarn (Warp yarn) and the yarn that runs horizontally (widthwise) of the fabric, called the weft or filling yarn.
General characteristics of woven fabric:

– The fabric has a relatively durable structure.

– Tightly covered surface.

– Elongation and elongation less horizontal.

– Easy to get dirty, especially with some fabrics like cotton, linen …

– Fabrics are not curled edge, not slip round.

– Diverse and abundant types of weaving and materials.

Knitting:

The process of forming a fabric by linking a system of loops together. The loops (eye threads) are linked together by the loom holding the old loop while a new loop is formed in front of the old loop. The old loop then goes through the new loop to form the fabric.

Knitting fabric consists of horizontal rows called courses and a vertical column is called a loop (Wales).

General characteristics of knitted fabric:

– Open surface, soft, porous.

– High elasticity and elasticity When bearing force, the stretch of the fabric is much larger than the woven fabric.

– Maintains good heat but does not hinder the metabolism between the human body and the surrounding environment.

– Few, easy to store and clean.

– Good hygiene in apparel.

– Create a pleasant feeling of wear.

– Cons: curly edges and easy to slip around.

Non-woven (Non-Woven)

In this process, fabric is called l; à non-woven fabric, made by attaching fibers together by not weaving or knitting but held together by a chemical binder or possibly by melt one of the fiber components within the fabric itself.
Conventional non-woven fabric is technical fabric so it can have very short shelf life, or is very durable; Can carry special functions for many different application areas such as: Can absorb water (absorbency) very well, can be hydrophobic (water repellency) or waterproof (water proof); Flame retardancy is very high; Softness (softness); Elasticity (Stretch); High strength (Strength); Insulation (Insulation); Anti-bacteria….

The scope of application of nonwoven fabric is very wide covering many areas of human life.

These are just basic concepts, providing visualization of the main and traditional methods of fabric creation. Nowadays, a lot of modern technology weaves into fabric which makes the traditional names no longer really appropriate. For example, we still use the traditional name as woven fabric, but actually weft weaving in “woven” fabric is no longer the role of “shuttle”, as on rapier, air weaving machine, water weaving … Or some fabric is a combination of woven and nonwoven method … We will discuss each method separately in the following articles.
