The basic characteristics of yarn include its appearance and shape, twisting characteristics, fiber transfer and distribution characteristics in the yarn, as well as the surface fuzz and internal looseness of the yarn. They are important features and expressions of yarn structure, determining the appearance and connotation quality of the yarn, and also affecting the properties of the fabric.

1. The influence of yarn structure on thermal insulation

The structural characteristics of yarn are inevitably related to the warmth retention of clothing, as the structure of yarn determines whether a stopping air layer can be formed between fibers.

The yarn structure is loose, with many gaps in the fabric, forming an air layer. When there is no wind, there is more air to stop, and the insulation is good; When there is wind, the air can smoothly pass between the yarns, so the coolness is better. For tightly structured yarns, the fabric woven from them also has a relatively tight structure, which obstructs air flow and provides better insulation; When the structure is too tight, the air trapped in the fabric is reduced, that is, the air reduction is stopped, and the insulation is poor.

2. The influence of yarn structure on moisture absorption

The moisture absorption of yarn depends on the fiber properties and yarn structure. If the long silk yarn is smooth, it is easy to stick to the body when woven into fabric. If the fabric is tight, it is difficult for moisture to penetrate the fabric. The surface of short fiber yarn has fuzz, which reduces contact with the skin and improves breathability, making it comfortable to wear.

3. The impact of yarn structure on durability

The tensile strength, elasticity, and wear resistance of yarn are influenced by the structure of the yarn.

The influence of yarn structure on pilling function: After one fiber in a long filament yarn cracks, one end still adheres to the yarn, and the cracked end bends on its own, causing pilling due to friction; Blended short fiber yarn has poor grip and is prone to detachment.

The effect on elasticity of short fiber yarn: Applying a certain external force to the short fiber yarn, the short fiber is straightened from bending, and the external force is removed, which can restore its elasticity; After the short fibers are straightened, if force is continued to be applied, they will slip or slide between each other, and withdrawing the external force will result in irreversible deformation.

Long filament yarn: When external force is applied to long filament yarn, its elasticity is relatively low because it does not bend and its degree of extension depends on the function of the fiber.

Twist also has a significant impact on elasticity: yarns with high twist have greater friction between fibers, making them less prone to stretching and relatively less elastic within the elastic range; And yarns with low twist have lower friction between fibers, making them relatively easier to stretch and have better elasticity.
