Classify yarns by structure

Yarn "is a continuous strip composed of textile fibers with certain mechanical properties, fineness, and flexibility.

The commonly referred to "yarn" actually refers to the collective term for "yarn" and "thread". "Yarn" is a slender object composed of many short fibers or long fibers arranged in an approximately parallel state, twisted and rotated along the axial direction to form a certain strength and linear density; And 'thread' is a strand of yarn made by twisting two or more single yarns together.

Yarn is the basic raw material of the textile industry, and its structure directly affects the feel, strength, and appearance of fabrics. According to its structure, it can be mainly divided into three categories: single yarn, stranded wire, and cable. Each type of yarn has its own specific purpose due to different forming methods.

Single yarn is the most basic yarn structure, which is composed of single or multiple fibers that are twisted and polymerized without the need for further twisting. It is divided into short fiber single yarn and long fiber single yarn. Short fiber single yarn is made by twisting short fibers such as cotton and wool, with natural feathers on the surface and a soft touch; Long filament single yarn is directly made from synthetic fibers, with a smooth surface and good glossiness. Single yarn has a simple structure and low production cost, but its strength is relatively low and it is prone to pilling and pilling.

Stranded yarn is made by combining and twisting two or more single yarns, also known as composite yarn. Its structure is compact, with strength and wear resistance far exceeding that of single yarn, and it is not easily deformed. The fuzz is also suppressed due to twisting. Common types of yarns include double stranded yarn and triple stranded yarn, with double stranded yarn and triple stranded yarn having higher strength. The luster and feel of the strands can be controlled by adjusting the single yarn specifications and twist.

A cable is made by combining and twisting two or more strands of wire again, with the most complex structure, extremely high strength, and good stability. It has a thicker diameter and is commonly used for heavy-duty fabrics.

In addition, there are some special structural yarns, such as core spun yarns, wrapped yarns, etc. Although they belong to derivative types, their essence is to optimize the structure based on single or stranded yarns to meet special functional requirements. Reasonable selection of yarns with different structures is the key to ensuring the quality and functionality of textile products.
