Yarn is a general term for yarns and threads, and yarns can be classified based on a variety of factors, including fiber composition, structure, twist, and manufacturing method. Yarn is a thin and soft continuous strip made of textile fibers with a certain thickness and physical and mechanical properties. Including yarn, thread and filament, etc.

There are many types of yarn, and yarns can be classified according to different starting points.

1. Staple yarn

Also known as single yarn, it is made of short fibers through spinning processing, so that the short fibers are arranged in the axial direction and twisted.

1) According to the spinning gauge and other process characteristics

Type yarn, wool type yarn, medium and long type yarn, linen spinning yarn, silk spinning yarn, uranium silk spinning yarn.

2) Subdivided according to the thickness of the yarn

Thickness classification of cotton and wool yarn

(The yarn count or special number range is only valid for the same fiber type)

2. Concept: continuous filament bundles directly spun from polymer solution.

According to the processing method after chemical fiber spinning.

(1) Draft yarn (FDY)

(2) Elastic yarn (DTY), including high elastic (deformed) yarn and low elastic (deformed) yarn

(3) Air textured yarn

(4) Network silk

3. Lines

Concept: It is made up of two or more single yarns combined and twisted; including composite yarn and structural yarn.

Multi-twisted strands: formed by combining and twisting two or more strands;

Fancy thread (yarn): It is a twisted combination of core yarn, decorative yarn and fixed yarn, with various special structural properties and appearance.

In addition to these classifications, yarns can be characterized by their count (thickness), density, elongation, color and performance properties such as abrasion resistance or moisture wicking capabilities.

The selection of yarn type depends on a variety of factors, including the intended use of the yarn, the desired properties of the fabric, and manufacturing considerations. Different yarn structures and compositions have specific properties suitable for various applications in the textile industry.
