What Is a Fabric Structure?

The fabric structure generally refers to the geometric structure of the fabric, which is the spatial relationship between warp and weft yarns in the fabric. The fabric structure has a great influence on the mechanical and physical properties of the fabric, and will affect the appearance effect of the fabric. Woven fabrics, knitted fabrics, and non-woven fabrics have different structural characteristics.

Fabric structure

Structural relationship of yarn

Cross relationship: The two groups of yarns contact each other alternately after the linear motion meets, forming a sine-cosine curve-like stable overlap relationship. Entanglement relationship: After the curved yarns meet, the inner side of the arc contacts to form a stable threading relationship. Connection relationship: Stable relationships between yarns that are close to or in contact with each other rely on external forces such as bonding.

Non-structural relationship

Point contact relationship, side-by-side contact relationship, separation relationship, these three relationships combined with the above three structural relationships together constitute a certain performance and stable fabric.

Generally composed of longitude and latitude

Knitted fabric (warp, weft) is mainly composed of longitudinal or horizontal

Yarn groups running in different directions, with adjacent yarns tangling forward and crossing each other after meeting, forming a new type of fabric, called the third fabric

The third fabric is a new fabric with a complete structure formed by intertwining the warp and weft yarns. The increased yarn density in the fabric makes it denser and denser. The existence of the two relationships makes the third fabric more elastic, more elastic than the woven fabric but not stiff, and less stretchable than the knitted fabric but not soft. (The warp knit loop-type entanglement has very little elasticity). The shape retention of the fabric is improved, and the problems of crimping, skewing, and loosening of the knitted fabric are reduced; the shortcomings of the woven fabric are easy to wrinkle, tear, and have low elasticity.

Textile fiber as raw material after bonding, fusing or

Fabric woven from three system yarns intersecting at an angle of 60 °

The yarn bends in different directions

If the yarn group is fixed by stitching and winding, a composite fabric can be formed.

Another important factor affecting the structure of various fabrics is the fiber material, the morphology and structure of the yarn. Due to the ever-changing fabric structure, the properties and morphology of the fabric also change. The modern textile processing methods are developing day by day, raw materials are constantly changing, and new products are emerging endlessly. The use of various fiber composites, mixed fibers, blended, mixed, mixed and different types of fabrics, and also added a variety of binders, compounds and coatings, to make the structure of textiles more complex, the finished product is also more colorful.
