Effect of yarn structure on fabric comfort and durability

　1 Warmth retention

The structural characteristics of the yarn have a certain relationship with the warmth retention of the garment, because the structure of the yarn determines whether the fibers can form a static state. air layer.

The yarn structure is fluffy, and there are more gaps in the fabric, forming an air layer. When there is no wind, there is more still air and better warmth retention; when there is wind, When the air passes through the yarns smoothly, the cooling effect is better.

For yarns with a tight structure, the fabric structure woven from them is also relatively tight, so the air flow is blocked and the warmth retention is better; and the structure When it is too tight, the air trapped in the fabric will be reduced, that is, the static air will be reduced, and the warmth retention will be poor.

2. Hygroscopicity

The hygroscopicity of yarn depends on fiber characteristics and yarn structure . If the filament yarn is smooth, the woven fabric will stick to the body easily. If the fabric is tight, it will be difficult for moisture to penetrate the fabric. The surface of the short fiber yarn is furry, which reduces contact with the skin, improves breathability and makes wearing comfortable.

2. The influence of yarn structure on durability

① Stretching of yarn Strength, elasticity, and abrasion resistance affect the durability of clothing. Affected by yarn structure.

②The influence of yarn structure on pilling performance: after one fiber in the filament yarn is broken, one end is still attached to the yarn, and the broken end curls itself , pilling due to friction; blended short fiber yarn has poor cohesion and is easy to fall out.

③ Effect on elasticity

Staple fiber yarn: Apply a certain amount of elasticity to the staple fiber yarn External force, the short fiber is straightened from the curl, and the elasticity can be restored if the external force is removed; and if the force is continued to be applied to the short fiber after it is straightened, the short fiber will slip or slip out, and then the external force will be removed. Unrecoverable deformation.

Filament yarn: When external force is applied to the filament yarn, since it does not curl, the degree of extension depends on the performance of the fiber, so its elasticity is small.

Twist also has a great influence on elasticity: yarns with large twists have large friction between fibers, so within the elastic range, they are not easily stretched. The elasticity is relatively poor; yarn with small twist has small friction between fibers, is relatively easy to be stretched, and has better elasticity.
