Yarn classification

Yarn is a continuous slender structure made from textile fibers through processes such as twisting and doubling. It serves as the fundamental material for weaving and knitting. Below is detailed information about yarn:

Basic Concepts

Definition

Yarn (single yarn): A slender object with a certain strength and linear density, formed by arranging numerous short fibers or filaments in an approximately parallel state and twisting them axially.

Thread (plied yarn): A stranded thread made by twisting two or more single yarns together.

Structural Composition

Yarn forms a stable structure by twisting fibers or filaments. Its twist level, thickness, and uniformity directly affect the yarn's strength, hand feel, and end-use.

Classification Methods

By Raw Material

Pure yarn: Spun from a single type of fiber material, such as cotton yarn and wool yarn.

Blended yarn: Spun from two or more types of fibers, such as polyester-cotton blended yarn.

By Fineness

Coarse count yarn: 32 tex and above.

Medium count yarn: 21-32 tex.

Fine count yarn: 11-20 tex.

Extra-fine count yarn: 10 tex and below.(Note: "Tex" is a unit of linear density, representing the mass in grams of a 1000-meter-long yarn.)

By Spinning System

Combed yarn: Produced through a combing process, featuring high parallelism and straightness of fibers.

Carded yarn: Produced without a combing process, containing a relatively high proportion of short fibers.

Waste yarn: Spun from textile waste or mixed with low-grade raw materials, resulting in relatively poor quality.

By Spinning Method

Ring-spun yarn

Open-end yarn: Including rotor-spun yarn, vortex-spun yarn, etc.

Non-open-end yarn: Including self-twisted yarn, air-jet spun yarn, etc.

By Yarn Structure

Single yarn, Plied yarn, Monofilament

Textured yarn: Including high-stretch yarn, low-stretch yarn, etc.

Fancy yarn: Including slub yarn, metallic yarn, printed yarn, etc.
